Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clindamycin is a lincosamide antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, blocking peptide bond formation.
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; 300-600 mg IM or IV every 6-8 hours; maximum 4.8 g/day IV.
600-2700 mg/day IV/IM in 2-4 divided doses. Typical: 600-900 mg IV q8h or 300-600 mg IM q12h.

2-3 hours in adults with normal renal function; prolonged to 8-12 hours in severe hepatic impairment; dialyzable but not clinically used for Clostridium difficile infection.
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% renal as active drug and metabolites, 90% fecal/biliary via enterohepatic circulation; <1% unchanged in urine.
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.
