The present invention provides compositions and methods for administering oxybutynin while minimizing the incidence and/or severity of adverse drug experiences associated with oxybutynin therapy. In one aspect, these compositions and methods provide a lower plasma concentration of oxybutynin metabolites, such as N-desethyloxybutynin, which is presumed to be contributing at least in part to some of the adverse drug experiences, while maintaining sufficient oxybutynin plasma concentration to benefit a subject with oxybutynin therapy. The invention also provides isomers of oxybutynin and its metabolites that meet these characteristics of minimized incidence and/or severity of adverse drug experiences, and maintenance of beneficial and effective therapy for overactive bladder. In some aspects, the composition may be presented in the form of an unoccluded or free form topically administered gel.
本发明提供了施用
奥昔布宁的组合物和方法,同时将与
奥昔布宁治疗相关的药物不良反应的发生率和/或严重程度降至最低。在一个方面,这些组合物和方法提供了较低的
奥昔布宁代谢物血浆浓度,如N-去乙酰氧基
奥昔布宁,据推测其至少部分导致了一些药物不良反应,同时保持足够的
奥昔布宁血浆浓度,使接受
奥昔布宁治疗的受试者获益。本发明还提供了
奥昔布宁及其代谢物的异构体,这些异构体符合将药物不良反应的发生率和/或严重程度降至最低,以及维持对膀胱过度活动症有益和有效治疗的这些特征。在某些方面,本发明的组合物可以未包封或游离形式的局部给药凝胶形式呈现。
