There is provided a suppository comprising at least one biocompatible polymer, wherein the biocompatible polymer is essentially non-biodegradable, and wherein the suppository essentially does not swell when contacted with an aqueous fluid. The suppository may further comprise a plurality of open cells at least partly separated from one another by an interpenetrating matrix comprising at least one biocompatible polymer in branched or crosslinked form. The plurality of interlinked, open cells are capable of containing an aqueous fluid, and the permeability of the suppository ensures that entry of body fluids into the open cells under practical circumstances occurs essentially without dehydration of mucousal membrane tissue contacting the suppository. The suppository furthermore preferably comprises a controlled release formulation.
提供了一种含有至少一种生物相容性聚合物的栓剂,其中该生物相容性聚合物基本上不可生物降解,且当与水性液体接触时,该栓剂基本上不膨胀。该栓剂还可以进一步包括多个开放单元,这些单元至少部分地由相互穿插的基质分隔开,该基质包含至少一种分支或交联形式的生物相容性聚合物。这些互相连接的开放单元能够包含水性液体,而栓剂的渗透性确保体液进入开放单元时,在实际情况下基本上不会导致接触栓剂的粘膜组织脱水。此外,该栓剂最好包含控制释放配方。
