Dual and single layer dosage forms
First Claim
1. A dual-release, dual-adhesiveness flexible thin film dosage form comprising:
- a mucoadhesive, planar quick-release subfilm comprising an admixture of polymers, which comprises (a) highly water-soluble polymer(s), (b) predominantly hydrophilic, bioadhesive polymer(s) and, uniformly distributed in the quick-release subfilm polymers, (c) a bioactive agent that is nicotine, naltrexone, lobeline or ondansetron, the polymers and other components of the quick-release subfilm adapted to provide 1 minute or more and 20 minutes or less erodibility for the quick-release subfilm; and
laminated against the quick-release subfilm, a mucoadhesive, planar sustained-release subfilm comprising an admixture of polymers, which comprises (i) predominantly hydrophilic, bioadhesive polymer(s), and, uniformly distributed in the sustained-release subfilm polymers, (ii) the bioactive agent, the polymers and other components of the sustained-release subfilm adapted to provide erodibility of 1 hour or more and 20 hours or less for the sustained-release subfilm, wherein both subfilms comprise (1) flavoring agent or agents and sweetener or sweeteners, (2) polyoxyethylenated castor oil derivative or derivatives and (3) di-glyceride or di-glycerides,the dosage form having a thickness of 30 mil or less, and being more adhesive on the sustained-release side, the dosage form having no additional layers, and wherein the dosage for is individually packaged in a moisture-resistant compartment.

Abstract
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 minutes 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 hour 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.
