DESCRIPTION
Clindamycin Phosphate Topical Solution USP, 1% contains clindamycin
phosphate USP at a
concentration equivalent to 10 mg clindamycin per milliliter.
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 solution contains isopropyl alcohol 50% v/v, propylene glycol,
purified water, and sodium
hydroxide (to adjust the pH to between 4.0 - 7.0).
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).
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
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 have
been decreased from approximately 14% to 2% following application of
clindamycin.
