Levonorgestrel

Descripción:
Levonorgestrel es un progestágeno sintético, utilizado principalmente en anticonceptivos hormonales y anticoncepción de emergencia. Se caracteriza por su capacidad para inhibir la ovulación, espesar el moco cervical y alterar el revestimiento endometrial, evitando así el embarazo. Químicamente, es un derivado de la norethisterona y pertenece a la clase de compuestos conocidos como derivados de 19-nortestosterona. Levonorgestrel se administra típicamente en varias formas, incluyendo tabletas orales, dispositivos intrauterinos (DIU) e implantes. Su fórmula molecular es C21H28O2, y tiene una lipofilia relativamente alta, lo que contribuye a su efectividad y duración de acción en el cuerpo. La sustancia generalmente es bien tolerada, pero puede tener efectos secundarios como náuseas, dolor de cabeza y cambios en los patrones de sangrado menstrual. Levonorgestrel también se utiliza en combinación con estrógeno en algunas formulaciones anticonceptivas. Su mecanismo de acción y farmacocinética lo convierten en un componente crucial en la gestión de la salud reproductiva.
