CLEOCIN PHOSPHATE vs CLINDAMYCIN PHOSPHATE
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.
Clindamycin inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, preventing peptide bond formation.
600-2700 mg/day IV/IM in 2-4 divided doses. Typical: 600-900 mg IV q8h or 300-600 mg IM q12h.
600 mg IV every 8 hours or 300-450 mg PO every 6 hours

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.
Terminal half-life 2-4 hours (prolonged to 8-12 hours in severe hepatic impairment; unchanged in renal failure)
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.
Renal 10% unchanged, fecal/biliary 90% as metabolites (mostly inactive)
