Clindamycin Phosphate

Clindamycin phosphate is a water-soluble ester of the semi-synthetic antibiotic clindamycin. It is used systemically via intravenous or intramuscular injection, topically for dermatological conditions like acne, or intravaginally. It works by binding to the 50S ribosomal subunit of susceptible bacteria, thereby preventing peptide bond formation and inhibiting bacterial protein synthesis.

Dosage by Body Weight

Dosage varies significantly based on the route of administration (topical, vaginal, or intravenous/intramuscular) and the severity of the infection. Systemic pediatric dosing is typically calculated by body weight at 20 to 40 mg/kg/day in 3 to 4 divided doses. Always follow a healthcare provider's precise instructions.
