    Inventor(s): Quan; Danyi & Deshpanday; Ninad A. & Venkateshwaran; Srinivasan & Ebert; Charles D.
    Assignee(s): TheraTech, Inc.
    A composition and method for enhancing transdermal penetration of a basic drug are described. The composition comprises a matrix patch comprising an effective amount of a basic drug, preferably having a pK.sub.a of about 8.0 or greater, an effective amount of penetration enhancer consisting essentially of triacetin, and a polymer later preferably comprising a pressure-sensitive adhesive. A preferred basic drug is oxybutynin and acid addition salts thereof. The method for enhancing transdermal penetration comprises applying the matrix patch to a selected area of skin.

  • Compositions and methods for minimizing adverse drug experiences associated with oxybutynin therapy
    Patent 6,743,441
    Issued: June 1, 2004
    Inventor(s): Steven W.; Sanders & Charles D.; Ebert
    Assignee(s): Watson Pharmaceuticals, Inc.
    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.

TermDefinition
Drug PatentA drug patent is assigned by the U.S. Patent and Trademark Office and assigns exclusive legal right to the patent holder to protect the proprietary chemical formulation. The patent assigns exclusive legal right to the inventor or patent holder, and may include entities such as the drug brand name, trademark, product dosage form, ingredient formulation, or manufacturing process A patent usually expires 20 years from the date of filing, but can be variable based on many factors, including development of new formulations of the original chemical, and patent infringement litigation.
Drug ExclusivityExclusivity is the sole marketing rights granted by the FDA to a manufacturer upon the approval of a drug and may run simultaneously with a patent. Exclusivity periods can run from 180 days to seven years depending upon the circumstance of the exclusivity grant.
RLDA Reference Listed Drug (RLD) is an approved drug product to which new generic versions are compared to show that they are bioequivalent. A drug company seeking approval to market a generic equivalent must refer to the Reference Listed Drug in its Abbreviated New Drug Application (ANDA). By designating a single reference listed drug as the standard to which all generic versions must be shown to be bioequivalent, FDA hopes to avoid possible significant variations among generic drugs and their brand name counterpart.
