:Levonorgestrel
Descrizione:
Levonorgestrel è un progestinico sintetico, utilizzato principalmente nei contraccettivi ormonali e nella contraccezione d'emergenza. È caratterizzato dalla sua capacità di inibire l'ovulazione, ispessire il muco cervicale e alterare il rivestimento endometriale, prevenendo così la gravidanza. Chimicamente, è un derivato della norethisterone e appartiene alla classe di composti noti come derivati del 19-nortestosterone. Levonorgestrel è tipicamente somministrato in varie forme, tra cui compresse orali, dispositivi intrauterini (IUD) e impianti. La sua formula molecolare è C21H28O2 e ha una lipofilia relativamente alta, che contribuisce alla sua efficacia e durata d'azione nel corpo. La sostanza è generalmente ben tollerata, ma può avere effetti collaterali come nausea, mal di testa e cambiamenti nei modelli di sanguinamento mestruale. Levonorgestrel è anche utilizzato in combinazione con estrogeni in alcune formulazioni contraccettive. Il suo meccanismo d'azione e farmacocinetica lo rendono un componente cruciale nella gestione della salute riproduttiva.
