DUAL AND SINGLE LAYER DOSAGE FORMS

摘要

Provided is a dual-release, dual-adhesiveness flexible thin film dosage form comprising: a quick-release subfilm comprising an admixture of polymer, which comprises predominantly highly water-soluble polymer(s), and a bioactive agent, the polymers and other components of the quick-release subfilm adapted to provide 20 minute or less erodibility for the quick-release subfilm; and laminated against the quick-release subfilm, a sustained-release subfilm comprising an admixture of polymer, which comprises predominantly hydrophilic, bioadhesive polymer(s), and a second bioactive agent, which can be the same as the first, the polymers and other components of the sustained-release subfilm adapted to provide erodibility of 1 hours or more and 20 hours or less for the sustained-release subfilm, the dosage form having a thickness of 30 mil or less, and being more adhesive on the sustained-release side.
