Resumen de: US2025235401A1
An oil in water nanoemulsion has an oil phase and an aqueous phase and comprises active pharmaceutical ingredient (API), edible oil, denatured plant protein, surfactant, and water, in which the API is contained in the oil phase. The API comprises an RNA molecule or a hydrophobic drug. The oil is high oleic oil. The oil in water nanoemulsion may be combined with a suspension of denatured plant protein and a calcium salt chelating agent to form microparticles or microcapsules comprising the nanoemulsion or the oil droplets of the nanoemulsion encapsulated within a denatured plant protein matrix. The microcapsules can be ingested orally and pass through the stomach to the ileum where the protein matrix breaks down to release the oil droplets containing the API, which is then absorbed.
