Drug Mode of Action ::  

Tretinoin is a trans-retinoic acid form of vitimin A. It stimulates mitosis and turnover of follicular epithelial cells and reduce their cohesiveness. This facilitates extrusion of existing comedones and prevents formation of new comedone. It also exhibits thinning effect on the stratum corneum. In acute promyelocytic leukaemia, it induces cellular differentiation and decreases proliferations.

Drug Interactions ::

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. Potentially Fatal: Increased risk of intracranial pressure with tetracyclines.
