After the diagnosis of pseudomembranous colitis has been established, therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation and treatment with an antibacterial drug clinically effective against C. difficile colitis.

Warnings

Pseudomembranous colitis has been reported with nearly all antibacterial agents, including erythromycin, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents.

Overdosage

FDA Package Insert for Erythromycin/Benzoyl Peroxide contains no information regarding overdose.

Pharmacology

There is limited information regarding Erythromycin/Benzoyl Peroxide Pharmacology in the drug label.

Mechanism of Action

The exact mechanism by which erythromycin reduces lesions of acne vulgaris is not fully known; however, the effect appears to be due in part to the antibacterial activity of the drug.

Benzoyl peroxide has a keratolytic and desquamative effect which may also contribute to its efficacy. Benzoyl peroxide has been shown to be absorbed by the skin where it is converted to benzoic acid.

Structure

Erythromycin/Benzoyl Peroxide® Topical Gel contains erythromycin [(3R*, 4S*, 5S*, 6R*, 7R*, 9R*, 11R*, 12R*, 13S*, 14R*)-4-[(2,6-Dideoxy-3-C-methyl-3-O-methyl-α-L-ribo-hexopyranosyl)-oxy]-14-ethyl-7,12,13-trihydroxy-3,5,7,9,11,13-hexamethyl-6-[ [3,4,6-trideoxy-3-(dimethylamino)-β-D-xylo-hexopyranosyl]oxy]oxacyclotetradecane-2,10-dione]. erythromycin is a macrolide antibiotic produced from a strain of Saccharopolyspora erythraea (formerly Streptomyces erythreus). It is a base and readily forms salts with acids.

Chemically, erythromycin is (C37H67NO13). It has the following structural formula:

Pharmacodynamics

FDA Package Insert for Erythromycin/Benzoyl Peroxide contains no information regarding Pharmacodynamics.

Pharmacokinetics

FDA Package Insert for Erythromycin/Benzoyl Peroxide contains no information regarding Pharmacokinetics.

Nonclinical Toxicology

CARCINOGENESIS, MUTAGENESIS AND IMPAIRMENT OF FERTILITY

Data from a study using mice known to be highly susceptible to cancer suggests that benzoyl peroxide acts as a tumor promoter. The clinical significance of this is unknown.

No animal studies have been performed to evaluate the carcinogenic and mutagenic potential or effects on fertility of topical erythromycin. However, long-term (2-year) oral studies in rats witherythromycin ethylsuccinate and erythromycin base did not provide evidence of tumorigenicity. There was no apparent effect on male or female fertility in rats fed erythromycin (base) at levels up to 0.25% of diet.

Clinical Studies

FDA Package Insert for Erythromycin/Benzoyl Peroxide contains no information regarding Clinical Studies.

How Supplied

This image is provided by the National Library of Medicine.

Prior to dispensing, tap vial until all powder flows freely. Add indicated amount of room temperature 70% ethyl alcohol to vial (to the mark) and immediately shake to completely dissolve erythromycin. Add this solution to gel and stir until homogeneous in appearance (1 to 1½ minutes). Erythromycin/Benzoyl Peroxide Topical Gel should then be stored under refrigeration. Do not freeze. Place a 3-month expiration date on the label.

Storage

Prior to reconstitution, store at room temperature between 15° and 30°C (59° – 86°F).

After reconstitution, store under refrigeration between 2° and 8°C (36° – 46°F).
