Clindamycin is a lincosamide antibiotic. It is usually used to treat infections with anaerobic bacteria but can also be used to treat some protozoal diseases, such as malaria. It is a common topical treatment for acne and can be useful against some methicillin-resistant Staphylococcus aureus (MRSA) infections.

The most severe common adverse effect of clindamycin is Clostridium difficile-associated diarrhea (the most frequent cause of pseudomembranous colitis).Although this side-effect occurs with almost all antibiotics, including beta-lactam antibiotics, it is classically linked to clindamycin use.

Clindamycin is marketed under various trade names, including CLINCIN, Dalacin, Clindacin, Cleocin, and Evoclin (clindamycin by itself), Duac, BenzaClin, and Clindoxyl and Acanya (in combination with benzoyl peroxide), and Ziana (with tretinoin). Clindamycin is also available as a generic drug.

Pharmacodynamics

Pharmacokinetics

Clindamycin inhibits protein synthesis by reversibly binding to the 50S subunit of the ribosomal thus blocking the transpeptidation or translocation reactions of susceptible organisms resulting to stunted cell growth.


Absorption
90% absorbed from the GI tract (oral), absorbed from the skin (topical), systemically (intravaginal); rate of absorption may be reduced by the presence of food.

Distribution
Body tissues and fluids (wide), bone, bile (high concentrations), leukocytes, macrophages; crosses the placenta and enters breast milk. Protein-binding: >90%

Metabolism

Hepatic; converted to N-demethyl and sulfoxide metabolites and some inactive metabolites.

Excretion
Via urine (10% as active drug or metabolites), via faeces (4% as inactive metabolites); 2-3 hours (elimination half-life), may be prolonged in preterm neonates and severe renal impairment.
