|fdaLIADAdult=* Ampicillin and sulbactam for injection is indicated for the treatment of infections due to susceptible strains of the designated microorganisms in the conditions listed below.
|offLabelAdultNoGuideSupport=There is limited information regarding <i>Off-Label Non–Guideline-Supported Use</i> of Ampicillin-Sulbactam in adult patients.
* Skin and Skin Structure Infections caused by beta-lactamase producing strains of [[Staphylococcus aureus]], [[Escherichia coli]], [[Klebsiella spp]] (including K. pneumoniae*), [[Proteus mirabilis]], [[Bacteroides fragilis]], [[Enterobacter]] spp.*, and [[Acinetobacter calcoaceticus]].
|offLabelPedGuideSupport=There is limited information regarding <i>Off-Label Guideline-Supported Use</i> of Ampicillin-Sulbactam in pediatric patients.
* Intra-Abdominal Infections caused by beta-lactamase producing strains of Escherichia coli, Klebsiella spp. (including K. pneumoniae), Bacteroides spp. (including B. fragilis), and Enterobacter spp.
|offLabelPedNoGuideSupport=There is limited information regarding <i>Off-Label Non–Guideline-Supported Use</i> of Ampicillin-Sulbactam in pediatric patients.
* Gynecological Infections caused by beta-lactamase producing strains of Escherichia coli, and Bacteroides spp. (including B. fragilis).
|contraindications=The use of Ampicillin and Sulbactam for Injection is contraindicated in individuals with a history of serious hypersensitivity reactions (e.g., anaphylaxis or Stevens-Johnson syndrome) to ampicillin, sulbactam or to other beta-lactam antibacterial drugs (e.g., penicillins and cephalosporins).
* Efficacy for this organism in this organ system was studied in fewer than 10 infections.
 
* While ampicillin and sulbactam for injection is indicated only for the conditions listed above, infections caused by ampicillin-susceptible organisms are also amenable to treatment with ampicillin and sulbactam for injection due to its ampicillin content. Therefore, mixed infections caused by ampicillin-susceptible organisms and beta-lactamase producing organisms susceptible to ampicillin and sulbactam for injection should not require the addition of another antibiotic.
Ampicillin and Sulbactam for Injection is contraindicated in patients with a previous history of cholestatic jaundice/hepatic dysfunction associated with Ampicillin and Sulbactam for Injection.
* Appropriate culture and susceptibility tests should be performed before treatment in order to isolate and identify the organisms causing infection and to determine their susceptibility to ampicillin and sulbactam for injection.
|warnings=Hypersensitivity
* Therapy may be instituted prior to obtaining the results from bacteriological and susceptibility studies, when there is reason to believe the infection may involve any of the beta-lactamase producing organisms listed above in the indicated organ systems. Once the results are known, therapy should be adjusted if appropriate.
Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients on penicillin therapy. These reactions are more apt to occur in individuals with a history of penicillin hypersensitivity and/or hypersensitivity reactions to multiple allergens. There have been reports of individuals with a history of penicillin hypersensitivity who have experienced severe reactions when treated with cephalosporins. Before therapy with a penicillin, careful inquiry should be made concerning previous hypersensitivity reactions to penicillins, cephalosporins, and other allergens. If an allergic reaction occurs, Ampicillin and Sulbactam for Injection should be discontinued and the appropriate therapy instituted.
* To reduce the development of drug-resistant bacteria and maintain effectiveness of ampicillin and sulbactam for injection and other antibacterial drugs, ampicillin and sulbactam for injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
 
* Ampicillin and sulbactam for injection may be administered by either the IV or the IM routes.
Hepatotoxicity
* For IV administration, the dose can be given by slow intravenous injection over at least 10-15 minutes or can also be delivered, in greater dilutions with 50-100 mL of a compatible diluent as an intravenous infusion over 15-30 minutes.
Hepatic dysfunction, including hepatitis and cholestatic jaundice has been associated with the use of Ampicillin and Sulbactam for Injection. Hepatic toxicity is usually reversible; however, deaths have been reported. Hepatic function should be monitored at regular intervals in patients with hepatic impairment.
* Ampicillin and sulbactam for injection may be administered by deep intramuscular injection.
 
* The recommended adult dosage of ampicillin and sulbactam for injection is 1.5 g (1 g ampicillin as the sodium salt plus 0.5 g sulbactam as the sodium salt) to 3 g (2 g ampicillin as the sodium salt plus 1 g sulbactam as the sodium salt) every six hours. This 1.5 to 3 g range represents the total of ampicillin content plus the sulbactam content of ampicillin and sulbactam for injection, and corresponds to a range of 1 g ampicillin/0.5 g sulbactam to 2 g ampicillin/1 g sulbactam. The total dose of sulbactam should not exceed 4 grams per day.
Clostridium difficile-Associated Diarrhea
|offLabelAdultGuideSupport=There is limited information regarding <i>Off-Label Guideline-Supported Use</i> of Ampicillin sodium and sulbactam sodium in adult patients.
Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including Ampicillin and Sulbactam for Injection, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.
|offLabelAdultNoGuideSupport=* Infection of skin AND/OR subcutaneous tissue
 
* Infectious disease of abdomen<ref name="pmidPMID: 9576376">{{cite journal| author=Ersoy FF, Sezer T, Sarikaya M, Süleymanlar G, Yakupoglu G| title=Treatment of CAPD peritonitis with intraperitoneal ampicillin/sulbactam-aminoglycoside combination. | journal=Perit Dial Int | year= 1998 | volume= 18 | issue= 2 | pages= 233-4 | pmid=PMID: 9576376 | doi= | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=9576376  }} </ref>
C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial drug use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.
* Pelvic inflammatory disease
 
|fdaLIADPed======Pediatric Patients 1 Year of Age or Older=====
If CDAD is suspected or confirmed, ongoing antibacterial drug use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.
* The recommended daily dose of ampicillin and sulbactam for injection in pediatric patients is 300 mg per kg of body weight administered via intravenous infusion in equally divided doses every 6 hours.
===Precautions===
* This 300 mg/kg/day dosage represents the total ampicillin content plus the sulbactam content of ampicillin and sulbactam for injection, and corresponds to 200 mg ampicillin/100 mg sulbactam per kg per day.
General
* The safety and efficacy of ampicillin and sulbactam for injection administered via intramuscular injection in pediatric patients have not been established. Pediatric patients weighing 40 kg or more should be dosed according to adult recommendations, and the total dose of sulbactam should not exceed 4 grams per day. The course of intravenous therapy should not routinely exceed 14 days. In clinical trials, most children received a course of oral antimicrobials following initial treatment with intravenous ampicillin and sulbactam for injection.
A high percentage of patients with mononucleosis who receive ampicillin develop a skin rash. Thus, ampicillin class antibacterials should not be administered to patients with mononucleosis. In patients treated with Ampicillin and Sulbactam the possibility of superinfections with mycotic or bacterial pathogens should be kept in mind during therapy. If superinfections occur (usually involving Pseudomonas or Candida), the drug should be discontinued and/or appropriate therapy instituted. Prescribing Ampicillin and Sulbactam for Injection in the absence of proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.

Information for Patients
|contraindications=* The use of ampicillin and sulbactam for injection is contraindicated in individuals with a history of hypersensitivity reactions to any of the penicillins.
Patients should be counseled that antibacterial drugs including Ampicillin and Sulbactam for Injection should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Ampicillin and Sulbactam for Injection is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Ampicillin and Sulbactam for Injection or other antibacterial drugs in the future.
|warnings=* SERIOUS AND OCCASIONALLY FATAL HYPERSENSITIVITY (ANAPHYLACTIC) REACTIONS HAVE BEEN REPORTED IN PATIENTS ON PENICILLIN THERAPY. THESE REACTIONS ARE MORE APT TO OCCUR IN INDIVIDUALS WITH A HISTORY OF PENICILLIN HYPERSENSITIVITY AND/OR HYPERSENSITIVITY REACTIONS TO MULTIPLE ALLERGENS.
 
* THERE HAVE BEEN REPORTS OF INDIVIDUALS WITH A HISTORY OF PENICILLIN HYPERSENSITIVITY WHO HAVE EXPERIENCED SEVERE REACTIONS WHEN TREATED WITH CEPHALOSPORINS. BEFORE THERAPY WITH A PENICILLIN, CAREFUL INQUIRY SHOULD BE MADE CONCERNING PREVIOUS HYPERSENSITIVITY REACTIONS TO PENICILLINS, CEPHALOSPORINS, AND OTHER ALLERGENS. IF AN ALLERGIC REACTION OCCURS, AMPICILLIN AND SULBACTAM FOR INJECTION SHOULD BE DISCONTINUED AND THE APPROPRIATE THERAPY INSTITUTED.
Diarrhea is a common problem caused by antibacterials which usually ends when the antibacterial is discontinued. Sometimes after starting treatment with antibacterials, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibacterial. If this occurs, patients should contact their physician as soon as possible.
* SERIOUS ANAPHYLACTOID REACTIONS REQUIRE IMMEDIATE EMERGENCY TREATMENT WITH EPINEPHRINE. OXYGEN, INTRAVENOUS STEROIDS, AND AIRWAY MANAGEMENT, INCLUDING INTUBATION, SHOULD ALSO BE ADMINISTERED AS INDICATED.
|clinicalTrials=Adult Patients
* Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including ampicillin and sulbactam for injection, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.
Ampicillin and Sulbactam for Injection is generally well tolerated. The following adverse reactions have been reported in clinical trials.
* C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after administration of antibacterial agents.
 
* If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment C. difficile, and surgical evaluation should be instituted as clinically indicated.

|postmarketing=In addition to adverse reactions reported from clinical trials, the following have been identified during post-marketing use of Ampicillin and Sulbactam for Injection or other products containing ampicillin. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These events have been chosen for inclusion due to a combination of their seriousness, frequency, or potential causal connection to Ampicillin and Sulbactam for Injection.
:* Presence of RBC's and hyaline casts in urine.
 
* The following adverse reactions have been reported with ampicillin-class antibiotics and can also occur with ampicillin and sulbactam for injection.
Blood and Lymphatic System Disorders: Hemolytic anemia, thrombocytopenic purpura, and agranulocytosis have been reported. These reactions are usually reversible on discontinuation of therapy and are believed to be hypersensitivity phenomena. Some individuals have developed positive direct Coombs Tests during treatment with Ampicillin and Sulbactam for Injection, as with other beta-lactam antibacterials.
=====Gastrointestinal=====
 
* Gastritis, stomatitis, black "hairy" tongue and enterocolitis. Onset of pseudomembranous colitis symptoms may occur during or after antibiotic treatment.  
Gastrointestinal Disorders: Cholestatic hepatitis, cholestasis, hyperbilirubinemia, jaundice, abnormal hepatic function, gastritis, stomatitis, black “hairy” tongue and Clostridium difficile associated diarrhea (see CONTRAINDICATIONSand WARNINGSsections).
=====Hypersensitivity Reactions=====
 
* Urticaria, erythema multiforme, and an occasional case of exfoliative dermatitis have been reported. These reactions may be controlled with antihistamines and, if necessary, systemic corticosteroids. Whenever such reactions occur, the drug should be discontinued, unless the opinion of the physician dictates otherwise. Serious and occasional fatal hypersensitivity (anaphylactic) reactions can occur with a penicillin.
General Disorders and Administration Site Conditions: Injection site reaction
* Hematologic
 
:* In addition to the adverse laboratory changes listed above for ampicillin and sulbactam for injection, [[agranulocytosis]] has been reported during therapy with penicillins. All of these reactions are usually reversible on discontinuation of therapy and are believed to be hypersensitivity phenomena. Some individuals have developed positive direct Coombs Tests during treatment with ampicillin and sulbactam for injection, as with other beta-lactam antibiotics.

Nervous System Disorders: Convulsion.
 
Renal and Urinary Disorders: Tubulointerstitial nephritis.
 
Skin and Subcutaneous Tissue Disorders: Toxic epidermal necrolysis, Stevens-Johnson syndrome, and acute generalised exanthematous pustulosis (AGEP), urticaria, erythema multiforme, and exfoliative dermatitis (see CONTRAINDICATIONSsection).
|drugInteractions=Probenecid decreases the renal tubular secretion of ampicillin and sulbactam. Concurrent use of probenecid with Ampicillin and Sulbactam may result in increased and prolonged blood levels of ampicillin and sulbactam. The concurrent administration of allopurinol and ampicillin increases substantially the incidence of rashes in patients receiving both drugs as compared to patients receiving ampicillin alone. It is not known whether this potentiation of ampicillin rashes is due to allopurinol or the hyperuricemia present in these patients. There are no data with Ampicillin and Sulbactam and allopurinol administered concurrently. Ampicillin and Sulbactam and aminoglycosides should not be reconstituted together due to the in vitro inactivation of aminoglycosides by the ampicillin component of Ampicillin and Sulbactam.
Drug/Laboratory Test Interactions
Administration of Ampicillin and Sulbactam will result in high urine concentration of ampicillin. High urine concentrations of ampicillin may result in false positive reactions when testing for the presence of glucose in urine using Clinitest™, Benedict's Solution or Fehling's Solution. It is recommended that glucose tests based on enzymatic glucose oxidase reactions (such as Clinistix™ or Testape™) be used. Following administration of ampicillin to pregnant women, a transient decrease in plasma concentration of total conjugated estriol, estriol-glucuronide, conjugated estrone and estradiol has been noted. This effect may also occur with Ampicillin and Sulbactam.

|useInPregnancyFDA=Reproduction studies have been performed in mice, rats, and rabbits at doses up to ten (10) times the human dose and have revealed no evidence of impaired fertility or harm to the fetus due to Ampicillin and Sulbactam. There are, however, no adequate and well controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.

|mechAction=* Ampicillin is similar to benzyl penicillin in its bactericidal action against susceptible organisms during the stage of active multiplication. It acts through the inhibition of cell wall mucopeptide biosynthesis. Ampicillin has a broad spectrum of bactericidal activity against many gram-positive and gram-negative aerobic and anaerobic bacteria. (Ampicillin is, however, degraded by beta-lactamases and therefore the spectrum of activity does not normally include organisms which produce these enzymes.)
* A wide range of beta-lactamases found in microorganisms resistant to penicillins and cephalosporins have been shown in biochemical studies with cell free bacterial systems to be irreversibly inhibited by sulbactam. Although sulbactam alone possesses little useful antibacterial activity except against the Neisseriaceae, whole organism studies have shown that sulbactam restores ampicillin activity against beta-lactamase producing strains. In particular, sulbactam has good inhibitory activity against the clinically important plasmid mediated beta-lactamases most frequently responsible for transferred drug resistance. Sulbactam has no effect on the activity of ampicillin against ampicillin susceptible strains.
* The presence of sulbactam in the ampicillin and sulbactam for injection formulation effectively extends the antibiotic spectrum of ampicillin to include many bacteria normally resistant to it and to other beta-lactam antibiotics. Thus, ampicillin and sulbactam for injection possesses the properties of a broad-spectrum antibiotic and a beta-lactamase inhibitor.
* While in vitro studies have demonstrated the susceptibility of most strains of the following organisms, clinical efficacy for infections other than those included in the indications section has not been documented.
=====Gram-Positive Bacteria=====
* Staphylococcus aureus (beta-lactamase and non-beta-lactamase producing), Staphylococcus epidermidis (beta-lactamase and non-beta-lactamase producing), Staphylococcus saprophyticus (beta-lactamase and non-beta-lactamase producing), Streptococcus faecalis† (Enterococcus), Streptococcus pneumoniae† (formerly D. pneumoniae), Streptococcus pyogenes†, Streptococcus viridans†.
=====Gram-Negative Bacteria=====
* Hemophilus influenzae (beta-lactamase and non-beta-lactamase producing), Moraxella (Branhamella) catarrhalis (beta-lactamase and non-beta-lactamase producing), Escherichia coli (beta-lactamase and non-beta-lactamase producing), Klebsiella species (all known strains are beta-lactamase producing), Proteus mirabilis (beta-lactamase and non-beta-lactamase producing), Proteus vulgaris, Providencia rettgeri, Providencia stuartii, Morganella morganii, and Neisseria gonorrhoeae (beta-lactamase and non-beta-lactamase producing).
=====Anaerobes=====
* Clostridium species†, Peptococcus species†, Peptostreptococcus species, Bacteroides species, including B. fragilis.
† These are not beta-lactamase producing strains and, therefore, are susceptible to ampicillin alone.
=====Susceptibility Testing=====
======Diffusion Technique======
* For the Kirby-Bauer method of susceptibility testing, a 20 mcg (10 mcg ampicillin + 10 mcg sulbactam) diffusion disk should be used. The method is one outlined in the NCCLS publication M2-A4.1 With this procedure, a report from the laboratory of "Susceptible" indicates that the infecting organism is likely to respond to ampicillin and sulbactam for injection therapy and a report of "Resistant" indicates that the infecting organism is not likely to respond to therapy. An "Intermediate" susceptibility report suggests that the infecting organism would be susceptible to ampicillin and sulbactam for injection if a higher dosage is used or if the infection is confined to tissues or fluids (e.g., urine) in which high antibiotic levels are attained.
======Dilution Techniques======
* Broth or agar dilution methods may be used to determine the minimal inhibitory concentration (MIC) value for susceptibility of bacterial isolates to ampicillin/sulbactam. The method used is one outlined in the NCCLS publication M7-A2.2 Tubes should be inoculated to contain 105 to 106 organisms/mL or plates "spotted" with 104 organisms.
* The recommended dilution method employs a constant ampicillin/sulbactam ratio of 2:1 in all tubes with increasing concentrations of ampicillin. MIC's are reported in terms of ampicillin concentration in the presence of sulbactam at a constant 2 parts ampicillin to 1 part sulbactam.

* Ampicillin and Sulbactam for Injection, USP, ampicillin sodium/sulbactam sodium parenteral combination, is available as a white to off-white dry powder for reconstitution. Ampicillin and Sulbactam for Injection, USP dry powder is freely soluble in aqueous diluents to yield pale yellow to yellow solutions containing ampicillin sodium and sulbactam sodium equivalent to 250 mg ampicillin per mL and 125 mg sulbactam per mL. The pH of the solutions is between 8 and 10.
* Dilute solutions (up to 30 mg ampicillin and 15 mg sulbactam per mL) are essentially colourless to pale yellow. The pH of dilute solutions remains the same.
* 1.5 g of Ampicillin and Sulbactam for Injection, USP (1 g ampicillin as the sodium salt plus 0.5 g sulbactam as the sodium salt) parenteral contains approximately 115 mg (5 mEq) of sodium.
* 3 g of Ampicillin and Sulbactam for Injection, USP (2 g ampicillin as the sodium salt plus 1 g sulbactam as the sodium salt) parenteral contains approximately 230 mg (10 mEq) of sodium.
|PK======General=====
* Immediately after completion of a 15-minute intravenous infusion of ampicillin and sulbactam for injection, peak serum concentrations of ampicillin and sulbactam are attained. Ampicillin serum levels are similar to those produced by the administration of equivalent amounts of ampicillin alone. Peak ampicillin serum levels ranging from 109 to 150 mcg/mL are attained after administration of 2000 mg of ampicillin plus 1000 mg sulbactam and 40 to 71 mcg/mL after administration of 1000 mg ampicillin plus 500 mg sulbactam. The corresponding mean peak serum levels for sulbactam range from 48 to 88 mcg/mL and 21 to 40 mcg/mL, respectively. After an intramuscular injection of 1000 mg ampicillin plus 500 mg sulbactam, peak ampicillin serum levels ranging from 8 to 37 mcg/mL and peak sulbactam serum levels ranging from 6 to 24 mcg/mL are attained.
* The mean serum half-life of both drugs is approximately 1 hour in healthy volunteers.
* Approximately 75 to 85% of both ampicillin and sulbactam are excreted unchanged in the urine during the first 8 hours after administration of ampicillin and sulbactam for injection to individuals with normal renal function. Somewhat higher and more prolonged serum levels of ampicillin and sulbactam can be achieved with the concurrent administration of probenecid.
* In patients with impaired renal function the elimination kinetics of ampicillin and sulbactam are similarly affected, hence the ratio of one to the other will remain constant whatever the renal function. The dose of ampicillin and sulbactam for injection in such patients should be administered less frequently in accordance with the usual practice for ampicillin.
* Ampicillin has been found to be approximately 28% reversibly bound to human serum protein and sulbactam approximately 38% reversibly bound.
* The following average levels of ampicillin and sulbactam were measured in the tissues and fluids listed:

Overview

Ampicillin-Sulbactam is an antibiotic that is FDA approved for the treatment of beta-lactamase producing strains of Staphylococcus aureus, Escherichia coli, Klebsiella spp. (including K. pneumoniae), Proteus mirabilis, Bacteroides fragilis, Enterobacter spp., and Acinetobacter calcoaceticus. Common adverse reactions include diarrhea.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

  • Ampicillin and sulbactam for injection is indicated for the treatment of infections due to susceptible strains of the designated microorganisms in the conditions listed below.
  • Skin and Skin Structure Infections caused by beta-lactamase producing strains of Staphylococcus aureus, Escherichia coli, Klebsiella spp (including K. pneumoniae*), Proteus mirabilis, Bacteroides fragilis, Enterobacter spp.*, and Acinetobacter calcoaceticus.
  • Intra-Abdominal Infections caused by beta-lactamase producing strains of Escherichia coli, Klebsiella spp. (including K. pneumoniae), Bacteroides spp. (including B. fragilis), and Enterobacter spp.
  • Gynecological Infections caused by beta-lactamase producing strains of Escherichia coli, and Bacteroides spp. (including B. fragilis).
  • Efficacy for this organism in this organ system was studied in fewer than 10 infections.
  • While ampicillin and sulbactam for injection is indicated only for the conditions listed above, infections caused by ampicillin-susceptible organisms are also amenable to treatment with ampicillin and sulbactam for injection due to its ampicillin content. Therefore, mixed infections caused by ampicillin-susceptible organisms and beta-lactamase producing organisms susceptible to ampicillin and sulbactam for injection should not require the addition of another antibiotic.
  • Appropriate culture and susceptibility tests should be performed before treatment in order to isolate and identify the organisms causing infection and to determine their susceptibility to ampicillin and sulbactam for injection.
  • Therapy may be instituted prior to obtaining the results from bacteriological and susceptibility studies, when there is reason to believe the infection may involve any of the beta-lactamase producing organisms listed above in the indicated organ systems. Once the results are known, therapy should be adjusted if appropriate.
  • To reduce the development of drug-resistant bacteria and maintain effectiveness of ampicillin and sulbactam for injection and other antibacterial drugs, ampicillin and sulbactam for injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
  • Ampicillin and sulbactam for injection may be administered by either the IV or the IM routes.
  • For IV administration, the dose can be given by slow intravenous injection over at least 10-15 minutes or can also be delivered, in greater dilutions with 50-100 mL of a compatible diluent as an intravenous infusion over 15-30 minutes.
  • Ampicillin and sulbactam for injection may be administered by deep intramuscular injection.
  • The recommended adult dosage of ampicillin and sulbactam for injection is 1.5 g (1 g ampicillin as the sodium salt plus 0.5 g sulbactam as the sodium salt) to 3 g (2 g ampicillin as the sodium salt plus 1 g sulbactam as the sodium salt) every six hours. This 1.5 to 3 g range represents the total of ampicillin content plus the sulbactam content of ampicillin and sulbactam for injection, and corresponds to a range of 1 g ampicillin/0.5 g sulbactam to 2 g ampicillin/1 g sulbactam. The total dose of sulbactam should not exceed 4 grams per day.

Off-Label Use and Dosage (Adult)

Guideline-Supported Use

There is limited information regarding Off-Label Guideline-Supported Use of Ampicillin sodium and sulbactam sodium in adult patients.

Non–Guideline-Supported Use

  • Infection of skin AND/OR subcutaneous tissue
  • Infectious disease of abdomen[1]
  • Pelvic inflammatory disease

Pediatric Indications and Dosage

FDA-Labeled Indications and Dosage (Pediatric)

Pediatric Patients 1 Year of Age or Older
  • The recommended daily dose of ampicillin and sulbactam for injection in pediatric patients is 300 mg per kg of body weight administered via intravenous infusion in equally divided doses every 6 hours.
  • This 300 mg/kg/day dosage represents the total ampicillin content plus the sulbactam content of ampicillin and sulbactam for injection, and corresponds to 200 mg ampicillin/100 mg sulbactam per kg per day.
  • The safety and efficacy of ampicillin and sulbactam for injection administered via intramuscular injection in pediatric patients have not been established. Pediatric patients weighing 40 kg or more should be dosed according to adult recommendations, and the total dose of sulbactam should not exceed 4 grams per day. The course of intravenous therapy should not routinely exceed 14 days. In clinical trials, most children received a course of oral antimicrobials following initial treatment with intravenous ampicillin and sulbactam for injection.

Off-Label Use and Dosage (Pediatric)

Guideline-Supported Use

There is limited information regarding Off-Label Guideline-Supported Use of Ampicillin sodium and sulbactam sodium in pediatric patients.

Non–Guideline-Supported Use

There is limited information regarding Off-Label Non–Guideline-Supported Use of Ampicillin sodium and sulbactam sodium in pediatric patients.

Contraindications

  • The use of ampicillin and sulbactam for injection is contraindicated in individuals with a history of hypersensitivity reactions to any of the penicillins.

Warnings

  • SERIOUS AND OCCASIONALLY FATAL HYPERSENSITIVITY (ANAPHYLACTIC) REACTIONS HAVE BEEN REPORTED IN PATIENTS ON PENICILLIN THERAPY. THESE REACTIONS ARE MORE APT TO OCCUR IN INDIVIDUALS WITH A HISTORY OF PENICILLIN HYPERSENSITIVITY AND/OR HYPERSENSITIVITY REACTIONS TO MULTIPLE ALLERGENS.
  • THERE HAVE BEEN REPORTS OF INDIVIDUALS WITH A HISTORY OF PENICILLIN HYPERSENSITIVITY WHO HAVE EXPERIENCED SEVERE REACTIONS WHEN TREATED WITH CEPHALOSPORINS. BEFORE THERAPY WITH A PENICILLIN, CAREFUL INQUIRY SHOULD BE MADE CONCERNING PREVIOUS HYPERSENSITIVITY REACTIONS TO PENICILLINS, CEPHALOSPORINS, AND OTHER ALLERGENS. IF AN ALLERGIC REACTION OCCURS, AMPICILLIN AND SULBACTAM FOR INJECTION SHOULD BE DISCONTINUED AND THE APPROPRIATE THERAPY INSTITUTED.
  • SERIOUS ANAPHYLACTOID REACTIONS REQUIRE IMMEDIATE EMERGENCY TREATMENT WITH EPINEPHRINE. OXYGEN, INTRAVENOUS STEROIDS, AND AIRWAY MANAGEMENT, INCLUDING INTUBATION, SHOULD ALSO BE ADMINISTERED AS INDICATED.
  • Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including ampicillin and sulbactam for injection, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.
  • C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after administration of antibacterial agents.
  • If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment C. difficile, and surgical evaluation should be instituted as clinically indicated.

Adverse Reactions

Clinical Trials Experience

There is limited information regarding Ampicillin-Sulbactam Clinical Trials Experience in the drug label.

Postmarketing Experience

Adult Patients
  • Ampicillin and sulbactam for injection is generally well tolerated. The following adverse reactions have been reported.
Local Adverse Reactions
  • Pain at IM injection site - 16%
  • Pain at IV injection site - 3%
  • Thrombophlebitis - 3%
Systemic Adverse Reactions
  • The most frequently reported adverse reactions were diarrhea in 3% of the patients and rash in less than 2% of the patients.
  • Additional systemic reactions reported in less than 1% of the patients were: itching, nausea, vomiting, candidiasis, fatigue, malaise, headache, chest pain, flatulence, abdominal distension, glossitis, urine retention, dysuria, edema, facial swelling, erythema, chills, tightness in throat, substernal pain, epistaxis and mucosal bleeding.
Pediatric Patients
  • Available safety data for pediatric patients treated with ampicillin and sulbactam for injection demonstrate a similar adverse events profile to those observed in adult patients. Additionally, atypical lymphocytosis has been observed in one pediatric patient receiving ampicillin and sulbactam for injection.
Adverse Laboratory Changes
  • Adverse laboratory changes without regard to drug relationship that were reported during clinical trials were:
  • Hepatic
  • Increased AST (SGOT), ALT (SGPT), alkaline phosphatase, and LDH.
  • Hematologic
  • Blood Chemistry
  • Decreased serum albumin and total proteins.
  • Renal
  • Increased BUN and creatinine.
  • Urinalysis
  • Presence of RBC's and hyaline casts in urine.
  • The following adverse reactions have been reported with ampicillin-class antibiotics and can also occur with ampicillin and sulbactam for injection.
Gastrointestinal
  • Gastritis, stomatitis, black "hairy" tongue and enterocolitis. Onset of pseudomembranous colitis symptoms may occur during or after antibiotic treatment.
Hypersensitivity Reactions
  • Urticaria, erythema multiforme, and an occasional case of exfoliative dermatitis have been reported. These reactions may be controlled with antihistamines and, if necessary, systemic corticosteroids. Whenever such reactions occur, the drug should be discontinued, unless the opinion of the physician dictates otherwise. Serious and occasional fatal hypersensitivity (anaphylactic) reactions can occur with a penicillin.
  • Hematologic
  • In addition to the adverse laboratory changes listed above for ampicillin and sulbactam for injection, agranulocytosis has been reported during therapy with penicillins. All of these reactions are usually reversible on discontinuation of therapy and are believed to be hypersensitivity phenomena. Some individuals have developed positive direct Coombs Tests during treatment with ampicillin and sulbactam for injection, as with other beta-lactam antibiotics.

Drug Interactions

There is limited information regarding Ampicillin-Sulbactam Drug Interactions in the drug label.

Use in Specific Populations

Pregnancy

Pregnancy Category (FDA): B

  • Reproduction studies have been performed in mice, rats, and rabbits at doses up to ten (10) times the human dose and have revealed no evidence of impaired fertility or harm to the fetus due to ampicillin and sulbactam for injection. There are, however, no adequate and well controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.


Pregnancy Category (AUS): There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Ampicillin-Sulbactam in women who are pregnant.

Labor and Delivery

  • Studies in guinea pigs have shown that intravenous administration of ampicillin decreased the uterine tone, frequency of contractions, height of contractions, and duration of contractions. However, it is not known whether the use of ampicillin and sulbactam for injection in humans during labor or delivery has immediate or delayed adverse effects on the fetus, prolongs the duration of labor, or increases the likelihood that forceps delivery or other obstetrical intervention or resuscitation of the newborn will be necessary.

Nursing Mothers

  • Low concentrations of ampicillin and sulbactam are excreted in the milk; therefore, caution should be exercised when ampicillin and sulbactam for injection is administered to a nursing woman.

Pediatric Use

  • The safety and effectiveness of ampicillin and sulbactam for injection have been established for pediatric patients one year of age and older for skin and skin structure infections as approved in adults. Use of ampicillin and sulbactam for injection in pediatric patients is supported by evidence from adequate and well-controlled studies in adults with additional data from pediatric pharmacokinetic studies, a controlled clinical trial conducted in pediatric patients and post-marketing adverse events surveillance.

Geriatic Use

There is no FDA guidance on the use of Ampicillin-Sulbactam in geriatric settings.

Gender

There is no FDA guidance on the use of Ampicillin-Sulbactam with respect to specific gender populations.

Race

There is no FDA guidance on the use of Ampicillin-Sulbactam with respect to specific racial populations.

Renal Impairment

Impaired Renal Function
  • In patients with impairment of renal function the elimination kinetics of ampicillin and sulbactam are similarly affected, hence the ratio of one to the other will remain constant whatever the renal function. The dose of ampicillin and sulbactam for injection in such patients should be administered less frequently in accordance with the usual practice for ampicillin and according to the following recommendations:

Hepatic Impairment

There is no FDA guidance on the use of Ampicillin-Sulbactam in patients with hepatic impairment.

Females of Reproductive Potential and Males

There is no FDA guidance on the use of Ampicillin-Sulbactam in women of reproductive potentials and males.

Immunocompromised Patients

There is no FDA guidance one the use of Ampicillin-Sulbactam in patients who are immunocompromised.

Administration and Monitoring

Administration

Monitoring

There is limited information regarding Ampicillin-Sulbactam Monitoring in the drug label.

IV Compatibility

There is limited information regarding the compatibility of Ampicillin-Sulbactam and IV administrations.

Overdosage

  • Neurological adverse reactions, including convulsions, may occur with the attainment of high CSF levels of beta-lactams. Ampicillin may be removed from circulation by hemodialysis. The molecular weight, degree of protein binding and pharmacokinetics profile of sulbactam suggest that this compound may also be removed by hemodialysis.

Mechanism of Action

  • Ampicillin is similar to benzyl penicillin in its bactericidal action against susceptible organisms during the stage of active multiplication. It acts through the inhibition of cell wall mucopeptide biosynthesis. Ampicillin has a broad spectrum of bactericidal activity against many gram-positive and gram-negative aerobic and anaerobic bacteria. (Ampicillin is, however, degraded by beta-lactamases and therefore the spectrum of activity does not normally include organisms which produce these enzymes.)
  • A wide range of beta-lactamases found in microorganisms resistant to penicillins and cephalosporins have been shown in biochemical studies with cell free bacterial systems to be irreversibly inhibited by sulbactam. Although sulbactam alone possesses little useful antibacterial activity except against the Neisseriaceae, whole organism studies have shown that sulbactam restores ampicillin activity against beta-lactamase producing strains. In particular, sulbactam has good inhibitory activity against the clinically important plasmid mediated beta-lactamases most frequently responsible for transferred drug resistance. Sulbactam has no effect on the activity of ampicillin against ampicillin susceptible strains.
  • The presence of sulbactam in the ampicillin and sulbactam for injection formulation effectively extends the antibiotic spectrum of ampicillin to include many bacteria normally resistant to it and to other beta-lactam antibiotics. Thus, ampicillin and sulbactam for injection possesses the properties of a broad-spectrum antibiotic and a beta-lactamase inhibitor.
  • While in vitro studies have demonstrated the susceptibility of most strains of the following organisms, clinical efficacy for infections other than those included in the indications section has not been documented.
Gram-Positive Bacteria
  • Staphylococcus aureus (beta-lactamase and non-beta-lactamase producing), Staphylococcus epidermidis (beta-lactamase and non-beta-lactamase producing), Staphylococcus saprophyticus (beta-lactamase and non-beta-lactamase producing), Streptococcus faecalis† (Enterococcus), Streptococcus pneumoniae† (formerly D. pneumoniae), Streptococcus pyogenes†, Streptococcus viridans†.
Gram-Negative Bacteria
  • Hemophilus influenzae (beta-lactamase and non-beta-lactamase producing), Moraxella (Branhamella) catarrhalis (beta-lactamase and non-beta-lactamase producing), Escherichia coli (beta-lactamase and non-beta-lactamase producing), Klebsiella species (all known strains are beta-lactamase producing), Proteus mirabilis (beta-lactamase and non-beta-lactamase producing), Proteus vulgaris, Providencia rettgeri, Providencia stuartii, Morganella morganii, and Neisseria gonorrhoeae (beta-lactamase and non-beta-lactamase producing).
Anaerobes
  • Clostridium species†, Peptococcus species†, Peptostreptococcus species, Bacteroides species, including B. fragilis.

† These are not beta-lactamase producing strains and, therefore, are susceptible to ampicillin alone.

Susceptibility Testing
Diffusion Technique
  • For the Kirby-Bauer method of susceptibility testing, a 20 mcg (10 mcg ampicillin + 10 mcg sulbactam) diffusion disk should be used. The method is one outlined in the NCCLS publication M2-A4.1 With this procedure, a report from the laboratory of "Susceptible" indicates that the infecting organism is likely to respond to ampicillin and sulbactam for injection therapy and a report of "Resistant" indicates that the infecting organism is not likely to respond to therapy. An "Intermediate" susceptibility report suggests that the infecting organism would be susceptible to ampicillin and sulbactam for injection if a higher dosage is used or if the infection is confined to tissues or fluids (e.g., urine) in which high antibiotic levels are attained.
Dilution Techniques
  • Broth or agar dilution methods may be used to determine the minimal inhibitory concentration (MIC) value for susceptibility of bacterial isolates to ampicillin/sulbactam. The method used is one outlined in the NCCLS publication M7-A2.2 Tubes should be inoculated to contain 105 to 106 organisms/mL or plates "spotted" with 104 organisms.
  • The recommended dilution method employs a constant ampicillin/sulbactam ratio of 2:1 in all tubes with increasing concentrations of ampicillin. MIC's are reported in terms of ampicillin concentration in the presence of sulbactam at a constant 2 parts ampicillin to 1 part sulbactam.

Pharmacodynamics

There is limited information regarding Ampicillin-Sulbactam Pharmacodynamics in the drug label.

Pharmacokinetics

General
  • Immediately after completion of a 15-minute intravenous infusion of ampicillin and sulbactam for injection, peak serum concentrations of ampicillin and sulbactam are attained. Ampicillin serum levels are similar to those produced by the administration of equivalent amounts of ampicillin alone. Peak ampicillin serum levels ranging from 109 to 150 mcg/mL are attained after administration of 2000 mg of ampicillin plus 1000 mg sulbactam and 40 to 71 mcg/mL after administration of 1000 mg ampicillin plus 500 mg sulbactam. The corresponding mean peak serum levels for sulbactam range from 48 to 88 mcg/mL and 21 to 40 mcg/mL, respectively. After an intramuscular injection of 1000 mg ampicillin plus 500 mg sulbactam, peak ampicillin serum levels ranging from 8 to 37 mcg/mL and peak sulbactam serum levels ranging from 6 to 24 mcg/mL are attained.
  • The mean serum half-life of both drugs is approximately 1 hour in healthy volunteers.
  • Approximately 75 to 85% of both ampicillin and sulbactam are excreted unchanged in the urine during the first 8 hours after administration of ampicillin and sulbactam for injection to individuals with normal renal function. Somewhat higher and more prolonged serum levels of ampicillin and sulbactam can be achieved with the concurrent administration of probenecid.
  • In patients with impaired renal function the elimination kinetics of ampicillin and sulbactam are similarly affected, hence the ratio of one to the other will remain constant whatever the renal function. The dose of ampicillin and sulbactam for injection in such patients should be administered less frequently in accordance with the usual practice for ampicillin.
  • Ampicillin has been found to be approximately 28% reversibly bound to human serum protein and sulbactam approximately 38% reversibly bound.
  • The following average levels of ampicillin and sulbactam were measured in the tissues and fluids listed:
This image is provided by the National Library of Medicine.
  • Penetration of both ampicillin and sulbactam into cerebrospinal fluid in the presence of inflamed meninges has been demonstrated after IV administration of ampicillin and sulbactam for injection.
  • The pharmacokinetics of ampicillin and sulbactam in pediatric patients receiving ampicillin and sulbactam for injection are similar to those observed in adults. Immediately after a 15-minute infusion of 50 to 75 mg ampicillin and sulbactam for injection/kg body weight, peak serum and plasma concentrations of 82 to 446 mcg ampicillin/mL and 44 to 203 mcg sulbactam/mL were obtained. Mean half-life values were approximately 1 hour.

  • Data from a controlled clinical trial conducted in pediatric patients provided evidence supporting the safety and efficacy of ampicillin and sulbactam for injection for the treatment of skin and skin structure infections.
  • Of 99 pediatric patients evaluable for clinical efficacy, 60 patients received a regimen containing intravenous ampicillin and sulbactam for injection, and 39 patients received a regimen containing intravenous cefuroxime. This trial demonstrated similar outcomes (assessed at an appropriate interval after discontinuation of all antimicrobial therapy) for ampicillin and sulbactam for injection - and cefuroxime - treated patients:

  • Most patients received a course of oral antimicrobials following initial treatment with intravenous administration of parenteral antimicrobials. The study protocol required that the following three criteria be met prior to transition from intravenous to oral antimicrobial therapy: 1) receipt of a minimum of 72 hours of intravenous therapy; 2) no documented fever for prior 24 hours; and 3) improvement or resolution of the signs and symptoms of infection.
  • The choice of oral antimicrobial agent used in this trial was determined by susceptibility testing of the original pathogen, if isolated, to oral agents available. The course of oral antimicrobial therapy should not routinely exceed 14 days.
