  • Patent number: 11890380
    Abstract: A buccal tablet formulation has a polyvinylpyrrolidone K-90 as a solid dispersion polymer, a hydroxypropyl methylcellulose as a mucoadhesive polymer, a sodium deoxycholate as mucopenetration enhancer, a porous silicon dioxide (e.g., FujiSil), mannitol, and avanafil. The ratio of PVP K-90 to AVA is approximately 2:1 (e.g., 2.3:1 to 1.7:1) in the tablet. Methods of making the buccal tablet with enhanced bioavailability and prolonged duration and methods of using the formulation for the treatment of erectile dysfunction are also provided.

  • Patent number: 10653634
    Abstract: Dapoxetine nanoparticles comprising zein and alpha lipoic acid (ALA) are provided. When present in zein-ALA loaded nanoparticles, dapoxetine exhibits increased bioavailability (compared to conventional formulations) when administered to subjects for the prevention or treatment of premature ejaculation (PE). Thus, lower doses are administered, and side effects are attenuated or eliminated.
