Latest Patents

Among his notable patents, the "Controlled release liquid dosage formulation" stands out. This invention discloses a liquid dual-coated dosage formulation designed for sustained release, ensuring a substantial shelf life before ingestion. The formulation involves applying dual coatings over controlled release cores, utilizing fats that melt at temperatures less than approximately 101°F, combined with cellulose acetate phthalate or zein. These dual-coated dosage forms are dispersed in a sugar-based acidic liquid carrier, such as high fructose corn syrup, enabling a shelf life of up to approximately 45 days while maintaining effective release profiles post-ingestion.

Another significant patent is the "Process of preparing microcapsules of lactides or lactide copolymers." This innovative method describes the preparation of polylactide (PLA) microcapsules through dissolving PLA in a mixture of two miscible organic liquids. By vaporizing the solvent-containing liquid, phase separation of PLA occurs, allowing for the encapsulation of core materials into microcapsules. This process facilitates the creation of true microcapsules that can encapsulate both aqueous and oily materials, which is a breakthrough in the microencapsulation field.
