- Patients with urge or mixed urinary incontinence, provided that stress urinary incontinence is not the predominant manifestation of mixed urinary incontinence
- Patients who are currently taking immediate release oxybutynin (Ditropan®) hyoscyamine (Levsin®) or propantheline (Pro-banthine®), or who have taken Ditropan in the past for urge or mixed UI. (Patients who have taken Ditropan for urge or mixed urinary incontinence, but who have discontinued the medication should have discontinued due to anticholinergic effects and not due to failure of efficacy)
- Patients who are able to differentiate incontinent episodes associated with urgency from incontinent episodes not associated with urgency when recording incontinent episodes in the diary, who have at least six urge urinary incontinence episodes per week recorded on the Run-in Diary after washout of anticholinergic medications, and who demonstrate that the number of urge incontinent episodes per week is greater than the number of incontinent episodes not associated with urgency per week
- Patients who are in good general health prior to study participation, having normal blood pressure with or without hypertension medication
- Agreeing that a medically acceptable and effective birth control method will be used by the patient and partner throughout the study and for one week following the end of the study

- Patients with known allergy or hypersensitivity to oxybutynin or clinically significant medical problems or other organ abnormality or pathology for whom, administration of oxybutynin would present undue risk
- Male patients with a PSA \> 10 ng/mL or a PSA between 4 ng/mL and 10 ng/mL who in the opinion of the investigator require further evaluation or treatment for prostate cancer, or male patients who have had prostate surgery less than nine months before study enrollment. (Prostate pathology from surgery must be benign)
- Patients whose estimated creatinine clearance is less than 50 mL/min or a have hemoglobin level less than 10 g/dL
