PG - e13379 LID - 10.1111/dth.13379 [doi] AB - Androgenetic alopecia (AGA) is a multifactorial disease that carries a significant psychological burden with it. Dihydrotestosterone, the main pathogenic androgen in AGA, is produced by conversion of testosterone, which is catalyzed by the 5-alpha reductase (5-AR) isoenzyme family. Finasteride and dutasteride are inhibitors of these enzymes. Finasteride, which is a single receptor 5-alpha reductase inhibitor (5-ARI), acts by blocking dihydrotestosterone (DHT). Dutasteride, a dual receptor DHT blocker, has a higher potency than its predecessor, finasteride. This review corroborates the evidence of superiority of dutasteride over finasteride, and its comparable safety profile concerning fertility, teratogenicity, neurotoxicity, and hepatotoxicity.
