Overview

IBS is heterogeneous in its presentation and treatment of IBS is based on predominant symptoms in the patient. There are no strict guidelines for the treatment of IBS and treatment is symptom-based.

Medical Therapy

Medical therapy of IBS

  • The multimodal treatment regimen is preferred for Irritable Bowel Syndrome (IBS).[1][2][3][4][5]
  • IBS is heterogeneous in its presentation, which makes it difficult to treat.[6]
  • All subtypes of IBS
    • Preferred regimen (1): Dietary measures: Low FODMAP high fiber diet for six-eight weeks
    • Preferred regimen (2): Moderate-severe exercise: Exercise for 30-60 mins 3-5 days a week for 12 weeks
    • Preferred regimen (2): Psychiatric referral in all IBS patients
  • Diarrhea-predominant IBS
    • Preferred regimen (1):  Loperamide 2 mg 45 minutes prior to a meal, as needed
    • Alternative regimen (1): Ondansetron 4 mg for five weeks
    • Alternative regimen (2): Colesevelam 1.875 g q12h
    • Alternative regimen (3): Gluten free diet for 2 weeks
  • Constipation-predominant IBS
    • Preferred regimen (1): Psylium half-one tbsp q24h, titrated based on response to therapy
    • Preferred regimen (2):17 g of PEG powder dissolved in 8 ounces of water q24h, may be titrated upto 34 g daily
    • Preferred regimen(3) : Lubiprostone 8 micrograms q12h for 12weeks
    • Preferred regimen (4) : Linaclotide 266 micrograms q24h for 12 weeks
    • Alternative regimen (1): Tageserod
  • Pain-predominant IBS:
    • Preferred regimen (1): Dicyclomine 20 mg po q6h as needed
      • Alternative regimen (1): Hyoscyamine 0.125 to 0.25 mg po q6h as needed
      • Alternative regimen (2): Sustained release hyoscyamine 0.375 to 0.75 mg po q12 hours as needed
    • Preferred regimen (2): Amitriptyline, Nortriptyline, or Imipramine 10 to 25 mg hs as needed
      • Alternative regimen (1):  Desipramine 12.5 to 25 mg hs as needed
  • Refractory IBS:
    • Preferred regimen (1): Rifaximin 550 mg q8h for 2 weeks


Dietary Measures

  • General instructions:[7][8][9][10][11][12][13]
    • Careful dietary history must be taken
    • Caffeine and alcohol avoidance decreases anxiety in patients
    • Legume avoidance decreases symptoms of flatulence
    • Skipping entire meals may worsen IBS symptoms
    • Avoidance of large meals
    • Reduced fat intake
    • Elimination diets help remove the most common dietary allergens[14][15][16]
    • Judicious water intake for the constipation-predominant IBS patients to prevent stool dehydration
    • Fiber supplementation
    • Schedule times for bowel evacuations and ensure intake of stimulating substances such as coffee prior to the scheduled time
    • Individualized dietary recommendations are preferable
    • Avoidance of gluten as gluten sensitivity may manifest in a subset of IBS patients [17][18][19][20]

Exclusion of gas-producing foods:

  • Beans, onions, celery, carrots, raisins, bananas, apricots, prunes, cabbage, onions, brussels sprouts, wheat germ, pretzels, and bagels
  • Low FODMAP diet:
    • A diet low in fermentable oligo-, di-, and monosaccharides and polyols (FODMAPs) is preferred in IBS patients.[12]
    • Education consists of: [10][14]
      • Elimination of dietary FODMAPs for 6-8 weeks
      • Reintroduction of foods high in FODMAPs to determine individual tolerance to specific foods
    • High FODMAP foods include: [21][22]
      • honey, mangoes cherries, high-fructose corn syrup, apples, pears, or oligosaccharides such as wheat
      • mannitol, sorbitol, fructose, lactose, fructans, xylitol, and galactans
      • sugar-alcohols such as isomalt, maltitol, erythritol, lactitol, mannitol and xylitol
    • High FODMAP foods are poorly absorbed by the gut and are osmotically active short chain carbohydrates.
    • Rapid fermentation of high FODMAP foods results in symptoms of abdominal discomfort and flatulence.[10][22][23][24]
  • Lactose avoidance:
    • IBS patients have more subjective lactose intolerance complaints (flatulence and diarrhea) as compared to other individuals.[25][26]
    • Lactose ingestion leads to production of hydrogen gas.
    • Bacterial fermentation of the unabsorbed lactose causes symptoms of bloating and distension.
    • Lactose intolerance can be diagnosed using breath testing.[27]
    • IBS patients with lactose intolerance should be given a lactose-restricted diet.[16][28][29][30]
  • Fiber in the diet:
    • Dietary fiber decreases symptoms of bloating in IBS patients. [16][31][32][33][34][35]
    • Soluble fibers are preferred as compared to insoluble fibers for treating symptoms of constipation.[36]

Physical activity 

  • Exercise plays an important role in relieving IBS symptoms by the following mechanisms :[7][33][37][38][39][40][41][42]
    • Reduction of stress
    • Protection against GI symptom aggravation
    • Alleviation of flatulence
    • Maintenance of GI function
    • Elevation of sympathetic tone, which is found to be decreased in IBS-D patients

Psychological therapy and counseling

  • It is necessary to build a good physician patient rapport due to the following reasons:[2][43][44][21][45][46][47][48][49][50][51][52]
    • IBS has a remarkably high placebo response rate
    • Patient regimens need to be individualized in IBS patients
    • Appropriate goals need to be set with emphasis on the chronic nature of the syndrome
    • Patient counseling plays an important role
  • The 2009 American College of Gastroenterologists (ACG) states that a psychiatric referral must be considered in all IBS patients.
  • Patients may be given the following therapies for symptom control:[1]
    • Cognitive-behavioral therapy
    • Interpersonal psychotherapy
    • Dynamic psychotherapy
    • Hypnotherapy
    • Antidepressants: Selective Serotonin Reuptake Inhibitors (SSRIs) and Tricyclic antidepressants (TCAs)
    • Behavior modification used in conjunction with antidepressants[53]
    • Anxiolytics 
      • Used for short-term (less than two weeks) reduction of acute situational anxiety in IBS patients
      • Side effects:
        • Benzodiazepines may lower pain thresholds by stimulating gamma aminobutyric acid (GABA) receptors, thereby decreasing brain serotonin
        • Drug interactions
        • High risk of habituation
        • Rebound withdrawal

Adjunctive pharmacologic therapy

Pharmacologic therapy is only preferred in patients where symptoms of IBS are moderate-severe and impair the quality of life.

Chloride channel activators

  • Mechanism of action:
    • Chloride channel activators are used for the constipation-predominant subtype of IBS and act by enhancing chloride-rich intestinal fluid secretions via guanylate cyclase activation.[51][54]
    • Chloride ion secretion is accompanied by the passive diffusion of water and sodium to maintain isotonicity.
  • Examples of chloride channel activators include:

5-hydroxytryptamine (serotonin) 3 receptor antagonists

  • 5-hydroxytryptamine-3 receptor (5HT-3) antagonists are useful in patients with severe refractory diarrhea-predominant IBS.[58][59][60][61][62]
  • The enteric neurons of the GI tract bear 5-HT3 receptors.
  • Stimulation of 5-HT3 receptors causes intestinal hyperactivity and hypersensitivity.
  • Alosetron (Lotronex): 5-hydroxytryptamine-3 receptor (5HT-3) antagonist[34][59][63][64]
    • Mechanism of action: Alosetron improves abdominal pain and diarrhea by affecting the visceral afferent activity of the GI tract leading to decreased colonic secretion and motility.

Side effects:

  • Ischemic colitis
  • Complications of severe constipation

5-hydroxytryptamine-4 (5-HT4) receptor agonists

  • 5HT4 receptor agonists are prokinetics or secretagogues used for constipation predominant cases of IBS.[65][66]
  • Mechanism of action:
    • Agonism of the 5-hydroxytryptamine-4 (5-HT4) receptor leads to increased motility of the colon
  • Tageserod: Partial 5-HT4 receptor agonist
    • Increased cardiovascular side effects

Antispasmodic agents [67][67][68][1][6]

  • Antispasmodic agents are of two types:
    • Mebeverine and Pinaverine directly affect intestinal smooth muscle relaxation.
      • Mechanism of action:
        • Antispasmodic agents cause selective inhibition of gastrointestinal smooth muscle, thereby reducing stimulated colonic motor activity [32]
      • Indication: IBS patients with post prandial abdominal pain, discomfort,distension and fecal urgency
      • Side effect: Constipation[1]
    • Anticholinergics
      • Mechanism of action: Anticholinergics decreased abdominal pain and fecal urgency by inhibing acetylcholine action at parasympathetic sites loacted in the secretory glands, smooth muscle and the CNS.
      • Examples of anticholinergic agents include:[64][67][69][70][71][72][73]
      • Dicyclomine hydrochloride (Bentyl)
        • Preferred dose : 20mg po q6h
      • Hyoscyamine sulfate (Levsin)
        •  0.125 to 0.25 mg po q12h
      • Side effects:
        • Urinary retention
        • Visual disturbances
        • Constipation
        • Dry mouth

Opioids

  • Mechanism of action: Nonabsorbable synthetic opioids act by the following mechanisms:[1][45][34][74][75][76]
    • Reduction in visceral nociception due to inhibition of the afferent pain pathway
    • Reduction in secretions via µ-opioid receptors in the periphery
    • Prolongation of GI transit time leading to improvement in stool consistency and reduction of stool frequency and volume
    • Inhibition of GI motility and peristalsis
  • Examples of opioids that act as effective antidiarrheal agents include:
    • Diphenoxylate hydrochloride (2.5 mg) with atropine sulfate (0.025 mg) (Lomotil):
      • Diphenoxylate is a meperidine congener that has a constipating effect.
      • The presence of atropine discourages abuse, due to anticholinergic side effects.
    • Loperamide (Imodium)- preferred as initial treatment for diarrhea in IBS patients
      • Preferred regimen:  2 mg 45 minutes before a meal on regularly scheduled doses
    • Eluxadoline (Viberzi): [77][78][79]
      • kappa opioid receptor agonist
      • mu opioid receptor agonist
      • delta opioid receptor antagonist
      • Side effects of Eluxadoline include:
        • Nausea
        • Constipation
        • Abdominal pain
        • Pancreatitis in a small fraction of patients
  • Side effects of opioids:
    • Addiction potential
    • Severe constipation

Bile acid sequestrants

  • 50 percent of patients with diarrhea predominant IBS have bile acid malabsorption. [80][81][82]
  • Stimulation of colonic motility and secretions by bile acids leads to diarrhea in patients.
  • Bile acid sequestrants are used as second-line therapy in diarrhea predominant IBS patients.
  • Examples:[34]
    • Cholestyramine
    •  Colestipol
    • Colesevelam
  • Side effects of bile acid sequestrants:
    • Flatulence
    • Abdominal discomfort
    • Constipation

Antidepressants

  • Antidepressants have analgesic and antidepressive effects and acts by the following mechanisms: [1][21][67][83][84][85][86][87][88][89][90]
    • Inhibition of serotonin which is the pain neuromodulator
    • Inhibition of norepinephrine which leads to stimulation of descending inhibitory pain pathways
    • Stimulation of endogenous endorphin release leading to mood improvement
    • Visceral analgesic effect by incresing pain threshold in the GI tract [91]
    • Tricyclic antidepressants cause slowing of intestinal transit time via anticholinergic properties thereby reducing abdominal pain, stool frequency and mucorrhea
  • In IBS patients with persistent pain in the abdomen despite use of antispasmodics, a trial of antidepressants is recommended.
  • Before increasing the dose of antidepressants, it is advised to wait for three to four weeks of therapy due to delayed onset of action.
  • Examples of antidepressants used for IBS include
    • Tricyclic antidepressants (TCAs): may be started at a dose of 10-25mg hs[92][93][94]
      • Amitriptyline (Elavil) [95][96]
      • Nortriptyline
      • Imipramine (Tofranil)
      • Desipramine 
    • In case of patient intolerance to a TCA agent, another drug may be administered.
  • Side effects of TCAs include:
    • Sedation
    • Constipation

Antibiotics

  • Routine antibiotic use is not recommended as benefit is transient in most IBS patients.
  • Post infectious IBS is due to the overgrowth of intestinal bacteria and may benefit from antibiotic use.
  • In moderate-severe refractory cases of IBS, a two week trial of antibiotics may be administered to patients. [97][98][99]
  • Rifaximin (Xifaxan): a semisynthetic Rifampin derivative[100][101]
  • Mechanism of action:
    • Binds beta-subunit of bacterial DNA-dependent RNA polymerase causing inhibition of transcription and thereby impairing bacterial protein synthesis
  • Preferred dose of Rifaximin: 550 mg PO q8h for 14 d [97][102]

Probiotics 

  •  Probiotics are not routinely recommended in IBS patients.
  • Probiotics have the following properties:[6][34][72][103][104][105][106]
  • Indications:
    • Abdominal pain
    • Bloating
    • Normalization of bowel habit in IBS patients

Bulk-Forming Laxatives

  • Bulk forming laxatives have the following properties:[6][45][35][67][107][108][109][110][111][112][113][114][115][116][117]
  • Composition:
    • Natural or semi-synthetic hydrophilic polysaccharides and cellulose derivatives.
  • Mechanism of action:
    • They facilitate intestinal passage and stimulate persistalsis by forming emolient gels in the water and increasing stool bulk.
  • Examples of some of the bulk-forming laxatives include:
    • Methylcellulose (Citrucel)
    • Psylium (Metamucil, Fiberall, Reguloid, Konsyl
    • Polyethylene glycol (PEG)- inexpensive and improves stool frequency in refractory cases [34][118]
    • Isapghula husk
    • Lactulose
    • Milk of magnesia  

Other therapies 

  • Other therapies have been evaluated in patients with IBS but their role remains uncertain.
  • These therapies are as follows:  [105][106][119][120]
    • Herbal medicines
    • Tight-junction modulators: Larazotide may be used for patients with evidence of increased mucosal permeability or immune activation.
    • Mast cell stabilizers: Ketotifen prevents mast cell activation that contributes to visceral hypersensitivity. [121][122]
    • Apuncture:[123][124]
      • Acupuncture acts on serotonergic, cholinergic, and glutamatergic pathways and causes reductions in blood cortisol level [125][126]
    • Relaxation techniques [127][128]
