  • Patent number: 9867786
    Abstract: A stabilized bioadhesive composition containing an alkaline labile drug and a method for its preparation are provided. In one aspect, the composition is a hot-melt extruded (HME) composition comprising a preformed excipient mixture comprising an acidic component and an alkaline thermoplastic matrix-forming material, e.g. polymer. The excipient mixture is formed before blending with an alkaline labile drug. The blend is then hot-melt extruded to form the HME composition. By so doing, the acidic component is able to neutralize or render moderately acidic the excipient mixture. This particular process has been shown to substantially reduce the degradation of an alkaline labile drug during hot-melt extrusion. The excipient mixture softens or melts during hot-melt extrusion. It can dissolve or not dissolve drug-containing particles during extrusion.

  • Patent number: 8465759
    Abstract: A process for the preparation of a bioadhesive laminate comprising a hot-melt extruded reservoir layer and a hot-melt extruded backing layer is provided. The reservoir layer comprises a thermoplastic bioadhesive composition containing an active agent. An active agent-containing thermoplastic bioadhesive hydrophilic composition is hot-melt coextruded with a hydrophobic composition to form at least a bi-layered laminate. The hydrophilic composition and the hydrophobic composition have at least one polymer in common. In addition, the melt flow index of the hydrophobic composition is within 50% of the melt flow index of the hydrophilic composition. As a result, the laminate has a uniform transverse cross-section and/or a uniform longitudinal cross-section throughout a major of the length of the laminate. Moreover, when the laminate is divided into unit doses of approximately the same size, they have a high degree of content uniformity with respect to the active agent(s) present therein.
