CLEOCIN PHOSPHATE vs CLINDAMYCIN HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clindamycin phosphate is a prodrug that is hydrolyzed to clindamycin. Clindamycin binds to the 50S subunit of bacterial ribosomes, inhibiting protein synthesis. It exhibits bacteriostatic activity against susceptible bacteria.
Binds to the 50S ribosomal subunit, inhibiting peptide bond formation and bacterial protein synthesis.
600-2700 mg/day IV/IM in 2-4 divided doses. Typical: 600-900 mg IV q8h or 300-600 mg IM q12h.
150-450 mg orally every 6 hours; maximum 1.8 g/day.

Terminal elimination half-life is 2-3 hours in adults with normal renal and hepatic function; may be prolonged to 4-5 hours in patients with severe hepatic impairment (Child-Pugh C). In neonates, half-life ranges from 8-12 hours, decreasing to adult values by 1 month of age.
The terminal elimination half-life of clindamycin is approximately 2-3 hours in adults with normal renal and hepatic function. In patients with severe hepatic impairment, half-life is prolonged to 8-12 hours. Renal impairment does not significantly alter half-life.
Approximately 10% as active drug and metabolites in urine, 3.6% in feces; major route is hepatic metabolism to inactive metabolites (N-demethylclindamycin and clindamycin sulfoxide) excreted in bile and feces. Renal excretion accounts for about 10% of the dose, with the remainder eliminated via biliary/fecal route.
Approximately 10-20% of clindamycin is excreted unchanged in urine; the remainder is hepatically metabolized and excreted in bile and feces as inactive metabolites. Fecal excretion accounts for about 4% of an administered dose as active drug and 60-70% as metabolites. Renal clearance is minor.
