PRESCRIPTION DRUG
Clindamycin Phosphate Topical Solution USP, 1% is indicated in the treatment of acne vulgaris. In view of the potential for diarrhea, bloody diarrhea and pseudomembranous colitis, the physician should consider whether other agents are more appropriate. (See CONTRAINDICATIONS , WARNINGS and ADVERSE REACTIONS. ) Clindamycin Phosphate Topical Solution USP, 1% is contraindicated in individuals with a history of hypersensitivity to preparations containing clindamycin or lincomycin, a history of regional enteritis or ulcerative colitis, or a history of antibiotic-associated colitis.

CLINDAMYCIN PHOSPHATE- CLINDAMYCIN PHOSPHATE SOLUTION E. FOUGERA & CO. ---------- CLINDAMYCIN PHOSPHATE PLEDGETS 1% (CLINDAMYCIN PHOSPHATE TOPICAL SOLUTION USP, 1%) RX ONLY FOR EXTERNAL USE DESCRIPTION Clindamycin Phosphate Topical Solution USP, 1% contains clindamycin phosphate, at a concentration equivalent to 10 mg clindamycin per milliliter. Each Clindamycin Phosphate Topical Solution pledget applicator contains approximately 1 mL of topical solution. The solution contains isopropyl alcohol 50% v/v, propylene glycol, and purified water. 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. The structural formula is represented below: The chemical name for clindamycin phosphate is: Methyl 7-chloro-6,7,8-trideoxy-6-(1-methyl-_trans_-4- propyl-L-2-pyrrolidinecarboxamido)-1-thio-L-_threo_-α-D-_galacto_-octopyranoside 2-(dihydrogen phosphate). pH between 4.0 and 7.0. CLINICAL PHARMACOLOGY Although clindamycin phosphate is inactive _in vitro_, rapid _in vivo_ hydrolysis converts this compound to the antibacterially active clindamycin. Cross resistance has been demonstrated between clindamycin and lincomycin. Antagonism has been demonstrated between clindamycin and erythromycin. Following multiple topical applications of clindamycin phosphate at a concentration equivalent to 10 mg clindamycin per mL in an isopropyl alcohol and water solution, very low levels of clindamycin are present in the serum (0–3 ng/mL) and less than 0.2% of the dose is recovered in urine as clindamycin. Clindamycin activity has been demonstrated in comedones from acne patients. The mean concentration of antibiotic activity in extracted comedones after application of Clindamycin Phosphate Topical Solution USP, 1% for 4 weeks was 597 mcg/g of comedonal material (range 0–1490). Clindamycin _in vitro_ inhibits all _Propionibacterium acnes_ cultures tested (MICs 0.4 mcg/mL). Free fatty acids on the skin surface hav Baca dokumen lengkap
