In light of the above presentation it will be appre assigned to the ALZA Corporation of Palo Alto, Calif. ciated by those versed in the medical and pharmaceutical dispensing arts to which this invention pertains that a FIELD OF THE INVENTION pressing need exists for a therapeutic method that can deliver the therapeutic drug oxybutynin in a controlled, 0002 This invention pertains to the management of Sustained-extended dose to a patient in clinical need of incontinence. More Specifically the invention relates to the incontinence management. The pressing need exists for an management of incontinence by administering to a patient oral method of therapy that can deliver oxybutynin alone at having the Symptoms of incontinence a therapeutically a Substantially Sustained release constant dose per unit time effective dose of oxybutynin alone, in combination with for its therapeutic effect. The need exists additionally for a another drug, proceeded by the administration of another method for delivering a dose of oxybutynin once-a-day, drug, or followed by the administration of another drug. when indicated, for its intended therapy while avoiding an Overdose and for lessening the Side effects that can accom BACKGROUND OF THE INVENTION pany the drug. The pressing need exists further for a method 0003. Many people are affected by urinary incontinence. that can administer Oxybutynin in combination with another Incontinence is particularly common in the elderly, urinary and different drug, or in different therapeutic programs for incontinence is present in approximately fifty percent of the management of incontinence and for the management of nursing home patients, and urinary incontinence is a well health and disease. known urologic problem in women. It will affect nearly all 0007. It will be appreciated by those skilled in the medi Women in Some form during their lifetime, and it is of cal and pharmaceutical arts to which this invention pertains, Significant medical and Social concern to all humans who that if a novel and unique method of administration is made experience it. Urinary incontinence arises from the anatomy available that delivers oxybutynin alone, or in combination and from the physiology of the urinary tract, which is with another drug in a therapeutically effective dose over a composed of a bladder and a Sphincter. Anatomically, the Sustained time for the management of incontinence, while bladder consists of the bladder musculature, also known as lessening the incidence of over and under dose, Such a detrusor, and the trigone. The Sphincter includes the bladder method of therapy would represent an advancement and a neck and the proximal urethra. The detrusor muscle is valuable contribution for providing practical therapy. innervated by the pelvic nerve through the parasympathetic nervous System, and the bladder neck and proximal urethra SUMMARY OF THE INVENTION are innervated by the Sympathetic nervous System. 0008 According to the invention, it is an object of the 0004. The major functions of the bladder are the storage invention to provide a method for the management of and expulsion of urine. The bladder is responsible for urinary incontinence with oxybutynin and/or its pharmaceu accommodating increasing Volumes of urine at low pres tically acceptable Salt alone, or in combination with another Sures.
