    Abstract: The invention provides microparticles for sustained release formulation for physostigmine, pyridostigmine and other therapeutically active carbamates. The microparticles comprise the active compound and a biodegradable polymer such as polyester, poly(phosphate), poly(anhydride), poly(ortho ester), or mixture thereof. In one embodiment, the polymer is poly(d,l-lactide-co-glycolide). The desired release pattern of the active compound may be readily attained by varying the type and amount of the polymer used, including by using a mixture of two polymers, one of which is more hydrophobic. The invention also provides a method of preparing the microparticles and in one embodiment, the microparticles may be prepared by spray drying.

    Abstract translation: 本发明提供用于毒扁豆黄素,吡斯的明和其他治疗活性氨基甲酸酯的持续释放制剂的微粒。 微粒包括活性化合物和可生物降解的聚合物如聚酯,聚(磷酸酯),聚(酸酐),聚(原酸酯)或其混合物。 在一个实施方案中,聚合物是聚(d,l-丙交酯 - 共 - 乙交酯)。 通过改变所用聚合物的类型和量可以容易地获得所需的活性化合物的释放模式,包括通过使用两种聚合物的混合物,其中一种是更疏水的。 本发明还提供了制备微粒的方法,在一个实施方案中,微粒可以通过喷雾干燥制备。
