Summary for Patent: 8,241,662

Title:Unoccluded topical oxybutynin gel composition and methods for transdermal oxybutynin therapy
Abstract: 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.

Non-Orange Book Patents for Patent: 8,241,662

For Orange Book-listed patents (shown in the main table above) generic applications must certify that the listed patents are expired, invalid, or will not be infringed by generic entry.

The non-Orange Book patents listed below do not require formal certifications, so they do not automatically impede generic entry. Instead, they represent potential opportunities for branded firms to block generic entry through patent infringment challenges.
