Latest Patents

Hwang's latest patents include a percutaneous absorption preparation containing donepezil and a patch containing rivastigmine. The first patent describes a transdermal delivery system in the form of a patch that features a double-layer structure. This structure includes a drug-containing matrix layer and an adhesive layer. The drug-containing matrix layer is created by completely dissolving donepezil using a specific polymer, which is then formulated with an adhesive. This innovative system ensures that there is no crystallization of donepezil in the formulation, allowing for a uniform release rate over an extended period. It also effectively inhibits the release dumping phenomenon commonly seen in single-layer transdermal systems. The second patent focuses on a rivastigmine-containing patch that boasts improved storage stability and optimal release properties.
