Interactions

Clindamycin: May enhance the action of neuromuscular blocking agents (e.g. atracurium). May antagonise the effects of parasympathomimetics. May competitively inhibit the effects of macrolides, ketolides, streptogramins, linezolid and chloramphenicol. Increased coagulation tests (prothrombin time/INR) and/or bleeding w/ vit K antagonists (e.g. warfarin, acenocoumarol, fluindione). Tretinoin: Enhances percutaneous absorption of minoxidil. Increased risk of fatal thrombotic complications with antifibrinolytic. Increased tretinoin concentrations with azole antifungals. Enhances peeling action of sulphur, resorcinol, benzoyl peroxide, salicylic acid. Increased photosensitivity with photosensitising medications eg, thiazides, tetracyclines, fluoroquinolones, phenothiazines and sulfonamides.

Mechanism of Action

Clindamycin: Antibacterial agent that binds to the 50S ribosomal subunits of susceptible bacteria and prevents elongation of peptide chains by interfering with peptidyl transfer, thereby suppressing protein synthesis; reduces surface fatty acids on skin; exact mechanism of action in treating acne unknown Tretinoin: Exact mechanism unknown; appears to cohesiveness of follicular epithelial cells with decrease microcomedo formation; also increases turnover of follicular cells to cause extrusion of comedones
