摘要： Pharmaceutical gastroretentive drug delivery systems for the controlled release of an active agent in the gastrointestinal tract are disclosed, which comprise: (a) a single- or multi-layered matrix comprising a polymer that does not retain in the stomach more than a conventional dosage form selected from (1) degradable polymers that may be hydrophilic polymers not instantly soluble in gastric fluids, enteric polymers substantially insoluble at pH less than 5.5 and/or hydrophobic polymers and mixtures thereof; (2) non-degradable polymers; and any mixtures of (1) and (2); (b) a continuous or non-continuous membrane comprising at least one polymer having a substantial mechanical strength; and (c) a drug; wherein the matrix when affixed or attached to the membrane prevents evacuation from the stomach of the delivery system for a period of time of from about 3 to about 24 hours.

摘要： A composition which comprises a biologically active agent and a polymer that exhibits a reverse thermal gelation at a physiological temperature, in a carrier, and in which the active agent is in an undissolved form is disclosed herein. Further disclosed herein are methods utilizing the compositions for treating subjects, including non-human subjects, as well as kits for preparing and using a composition. The composition is preferably a sustained release formulation, and is particularly useful for treating animals, where single-dose treatment is desired.
