polymer compositions and dosage forms comprising the same |
| abstract |
"POLYMERIC COMPOSITIONS AND METHODS OF UNDERSTANDING THE SAME". The present invention relates to a dosage form comprising: (a) at least one active ingredient; (b) a core having an outer surface; and (c) a shell residing on at least a core portion of the outer surface, where at least a portion of the shell may be semipermeable, such that the liquid medium diffuses through the semipermeable shell or portion of the shell into the core due to osmosis. The shell also provides for the release of the active ingredient into the liquid medium outside the shell after contacting the dosage form with the liquid medium. At least a portion of the shell may be comprised of a polymeric composition containing the film former, gelling agents, which may be dissolved in a multi-solvent system comprised of water and an organic solvent. |
