Action
Description: Tazarotene, a synthetic acetylenic retinoid, is a prodrug which is converted to tazarotenic acid then binds to 3 retinoic acid receptors but has relative selectivity for RARβ and RARγ. It regulates gene expression, thus modulating cell proliferation, differentiation, and hyperplasia.
Pharmacokinetics:
Distribution: Plasma protein binding: highly bound as tazarotenic acid (>99%).
Metabolism: Metabolised via esterase hydrolysis to tazarotenic acid and via oxidation to inactive sulfoxides, sulfones, and other polar metabolites.
Excretion: Via urine and faeces. Elimination half-life: Approx 18 hr.
