摘要

Novel pharmaceutical compositions comprising at least one active agent(s) or its pharmaceutically acceptable salts, polymorphs, solvates, hydrates, analogues, enantiomers, tautomeric forms or mixtures thereof; at least one permeation enhancer(s); at least one adsorbent(s) and at least one bioadhesive polymer(s); optionally at least one acid soluble polymer(s) and optionally one or more other pharmaceutically acceptable excipient(s) are provided. Preferably the compositions are in the gastro-adhesive modified release form and/or fast disintegrating dosage form which release the active agent(s) over an extended period of time. Also provided are processes of preparation of such novel compositions and methods of using them.
