  • Patent number: 11975000
    Abstract: The present invention provides an oral transmucosal film for delivering tadalafil through the buccal mucosa or sublingual mucosa. The film is a single layer structure containing amorphous tadalafil, one or more solubilizers, one or more penetration enhancers, and one or more adhesives to deliver the drug through a transmucosal route. Comparing with an oral tadalafil tablet, the present oral transmucosal film provides improved absorption rate and Tmax. The oral transmucosal film comprises 5%-60% by weight of amorphous tadalafil, 25-96% by weight of a film-forming material, 1-20% by weight of a solubilizer, 0.5-10% by weight of a penetration enhancer, and 1-15% by weight of an adhesive.
