    • A hot-melt extruded composition having finely divided drug-containing particles dispersed within a polymeric and/or lipophyllic carrier matrix is provided. The carrier softens or melts during hot-melt extrusion but it does not dissolve the drug-containing particles during extrusion. As a result, a majority or at least 90% wt. of the drug-containing particles in the extrudate are deaggregated during extrusion into essentially primary crystalline and/or amorphous particles. PEO is a suitable carrier material for drugs insoluble in the solid state in this carrier. Various functional excipients can be included in the carrier system to stabilize the particle size and physical state of the drug substance in either a crystalline and/or amorphous state. The carrier system is comprised of at least one thermal binder, and may also contain various functional excipients, such as: super-disintegrants, antioxidants, surfactants, wetting agents, stabilizing agents, retardants, or similar functional excipients. A hydrophilic polymer, such as hydroxypropyl methylcellulose (HPMC E15), polyvinyl alcohol (PVA), or poloxamer, and/or a surfactant, such as sodium lauryl sulfate (SLS), can be included in the composition. A process for preparing the extrudate is conducted at a temperature approximating or above the softening or melting temperature of the matrix and below the point of solubilization of drug-containing particles in the carrier system, and below the recrystallization point in the case of amorphous fine drug particles.

    • The present invention includes compositions and methods of making a modified release pharmaceutical formulation and a method of preparation for the embedding of modified release multi-particulates into a polymeric or wax-like matrix. The modified release multi-particulates comprise an effective amount of a therapeutic compound having a known or desired drug-release profile. Modified release multi-particulates may include a polymeric coat or may be incorporated into particle or core material. The polymer matrix comprises a thermoplastic polymer or lipophilic carrier or a mixture thereof that softens or melts at elevated temperature and allows the distribution of the modified release multi-particulates in the polymer matrix during thermal processing. Formulation compounds and processing conditions are selected in a manner to preserve the controlled release characteristics and/or drug-protective properties of the original modified release multi-particulates.

    • Disclosed here are effervescent granules having a controllable rate of effervescence. In some embodiments, the such granules comprise an acidic agent, an alkaline agent, a pharmacologically active agent, hot-melt extrudable binder capable of forming a eutectic mixture with the acidic agent and, optionally, a plasticizer. The effervescent granules are made by a hot-melt extrusion process. The present invention also provides a thermal heat process for preparing a pharmacologically active agent containing effervescent granule. In certain aspects, the granules contain pharmacologically active agents such as narcotics, antidiarrheal agents, antiviral agents, anxiolytic agents, a cholesterol lowering agent, an alpha adrenergic blocking agent, a phenanthrene derivative. By way of example, some of the narcotics that may be included in the granules and in the process of preparing the granules include, by way of example: phenanthrene derivatives (e.g., morphine sulfate), and morphine derivatives (e.g., hydromorphone hydrochloride).
