Abstract

La presente invención se refiere a una composición farmacéutica de sildenafil de liberación pulsátil que comprende una fracción de liberación inmediata que contiene 5 a 100 mg de sildenafil y una fracción de liberación controlada que contiene 25 a 150 mg de sildenafil, en donde la fracción de liberación controlada está compuesta por partículas que contienen (a) un agente superdesintegrante, (b) un recubrimiento formado por al menos un polímero de solubilidad pH-dependiente y al menos un polímero de solubilidad pH-independiente y (c) opcionalmente otros excipientes farmacéuticos. La composición de la presente invención presenta un perfil de disolución más rápido en medio alcalino que en medio ácido, lo que permite obtener formulaciones mejoradas de liberación pulsátil.
