Mechanism and action
Ativan: Le lorazépam se lie au site benzodiazépine du récepteur GABA-A et renforce de façon allostérique la conductance chlorure inhibitrice. 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 ».
