Clindamycin phosphate is a water soluble ester of the semi-synthetic antibiotic produced by a 7(S)-chloro-substitution of the 7(R)-hydroxyl group of the parent antibiotic lincomycin. Chemically, clindamycin phosphate is (C 18 H 34 ClN 2 O 8 PS). The structural formula for clindamycin is represented below: Clindamycin phosphate has a molecular weight of 504.97 and its chemical name is Methyl 7-chloro-6,7,8-trideoxy-6-(1-methyl-trans-4-propyl-L-2-pyrrolidinecarboxamido) - 1-thio-L- threo-alpha-D-galacto-octopyranoside 2-(dihydrogen phosphate). Clindamycin and benzoyl peroxide topical gel, 1%/5% also contains benzoyl peroxide, for topical use. Chemically, benzoyl peroxide is (C 14 H 10 O 4 ). It has the following structural formula: Benzoyl peroxide has a molecular weight of 242.23. Each gram of clindamycin and benzoyl peroxide topical gel, 1%/5% contains, as dispensed, 10 mg (1%) clindamycin as phosphate and 50 mg (5%) benzoyl peroxide in a base of carbomer homopolymer type C, sodium hydroxide, dioctyl sodium sulfosuccinate, and purified water.

Side Effects Overview

ADVERSE REACTIONS During clinical trials, the most frequently reported adverse event in the clindamycin and benzoyl peroxide topical gel, 1%/5% treatment group was dry skin (12%). The Table below lists local adverse events reported by at least 1% of patients in the clindamycin and benzoyl peroxide topical gel, 1%/5% and vehicle groups. Local Adverse Events – all causalities in >/= 1% of patients Clindamycin and benzoyl peroxide topical gel, 1%/5% n=420 Vehicle n=168 Application site reaction 13 (3%) 1 (<1%) Dry skin 50 (12%) 10 (6%) Pruritus 8 (2%) 1 (<1%) Peeling 9 (2%) - Erythema 6 (1%) 1 (<1%) Sunburn 5 (1%) - The actual incidence of dry skin might have been greater were it not for the use of a moisturizer in these studies. Anaphylaxis, as well as allergic reactions leading to hospitalization, have been reported during post-marketing use of clindamycin/benzoyl peroxide products. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Pharmacokinetics: The pharmacokinetics (plasma and urine) of clindamycin from clindamycin and benzoyl peroxide topical gel, 1%/5% was studied in male and female patients (n=13) with acne vulgaris. Clindamycin and benzoyl peroxide topical gel, 1%/5% (~2g) was applied topically to the face and back twice daily for four and a half (4.5) days. Quantifiable (>LOQ=1ng/mL) clindamycin plasma concentrations were obtained in six of thirteen subjects (46.2%) on Day 1 and twelve of thirteen subjects (92.3%) on Day 5. Peak plasma concentrations (C max ) of clindamycin ranged from 1.47 ng/mL to 2.77 ng/mL on Day 1 and 1.43 ng/mL to 7.18 ng/mL on Day 5. The AUC (0-12h) ranged from 2.74 ng.h/mL to 12.86 ng.h/mL on Day 1 and 11.4 ng.h/mL to 69.7 ng.h/mL on Day 5. The amount of clindamycin excreted in the urine during the 12 hour dosing interval increased from a mean (SD) of 5745 (3130) ng on Day 1 to 12069 (7660) ng on Day 5. The mean % (SD) of the administered dose that was excreted in the urine ranged from 0.03% (0.02) to 0.08% (0.04). A comparison of the single (Day 1) and multiple (Day 5) dose plasma and urinary concentrations of clindamycin indicates that there is accumulation of clindamycin following multiple dosing of clindamycin and benzoyl peroxide topical gel, 1%/5%. The degree of accumulation calculated from the plasma and urinary excretion data was ~2-fold.
