Mechanism and action
Avodart: Avodart inhibe les deux isoformes de la 5α-réductase, l'enzyme qui convertit la testostérone en dihydrotestostérone (DHT). Ovestin: L'estriol contenu dans Ovestin se lie aux récepteurs des estrogènes avec une occupation réceptorielle plus brève que l'estradiol, produisant un effet estrogénique dit « faible ».
