Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clindamycin hydrochloride is a lincosamide antibiotic that inhibits bacterial protein synthesis by binding to the 50S subunit of the ribosome, thereby interfering with peptide bond formation and chain elongation.
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.
150-450 mg orally every 6 hours (oral capsules). Maximum dose: 1.8 g/day.
600-2700 mg/day IV/IM in 2-4 divided doses. Typical: 600-900 mg IV q8h or 300-600 mg IM q12h.

Terminal elimination half-life is approximately 2.4 to 3.0 hours in adults with normal renal and hepatic function. In patients with severe hepatic impairment, half-life may be prolonged up to 8.5 hours. No significant change in renal impairment.
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.
Approximately 10% of the active drug is excreted in urine as unchanged clindamycin; about 3.6% in feces; remainder is metabolized primarily in liver. Renal excretion accounts for ~10% of elimination, biliary/fecal route accounts for ~90% including metabolites.
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.
