Corona, Calif. – February 26, 2003 – Watson Pharmaceuticals, Inc. (NYSE: WPI), announced today that the U.S. Food and Drug Administration (FDA) has approved OXYTROL tm (oxybutynin transdermal system), the first and only transdermal therapy to treat overactive bladder (OAB), with symptoms of urge urinary incontinence, urgency and frequency. Estimated to affect more than 33 million Americans, OAB is more common than both diabetes and asthma.

"The approval of OXYTROL marks an important milestone for Watson," said Allen Chao, Chairman and Chief Executive Officer. "As a company committed to developing products that enhance the standard of care for patients, we believe OXYTROL's innovative transdermal delivery will provide OAB sufferers with a much needed treatment option. In addition, OXYTROL's approval strengthens Watson's position as a leading generic and specialty brand pharmaceutical company."

Proven Efficacy with Anticholinergic Side Effects Comparable to Placebo

Clinical trials involving more than 1,000 subjects at over 50 U.S. centers showed that OXYTROL provides effective control of OAB symptoms over a three to four day period. Data also show that OXYTROL is well tolerated, with anticholinergic side effects, such as dry mouth and constipation, comparable to placebo. The most common adverse events occurring with OXYTROL were application site reactions.

"Side effects have long been a leading cause of treatment discontinuation among my patients suffering from overactive bladder," said Roger Dmochowski, M.D., Professor of Urology, Vanderbilt University and OXYTROL study investigator. "OXYTROL's transdermal delivery system provides physicians and patients with a convenient new treatment option to help manage the symptoms of overactive bladder with anticholinergic side effects comparable to a placebo patch. I am thrilled to have this important new treatment to offer my patients coping with this condition."

About OXYTROL
OXYTROL is a thin, flexible and clear patch that should be applied to the abdomen, hip or buttock twice weekly. The active ingredient in OXYTROL™ is oxybutynin, a medication widely accepted and prescribed in oral formulation for the past 25 years. OXYTROL's transdermal delivery system delivers 3.9 milligrams per day of oxybutynin consistently and continuously through the skin into the bloodstream, bypassing initial metabolism in the liver and the gastrointestinal tract that occurs with oral medications, providing relief of overactive bladder symptoms for up to four days. Patients who have urinary retention, gastric retention, uncontrolled narrow-angle glaucoma or hypersensitivity to oxybutynin or other components of OXYTROL should not use OXYTROL.

About Overactive Bladder
OAB is defined as urgency, with or without urge incontinence and usually includes frequency and nocturia (waking up one or more times during the night to urinate). The condition is characterized by involuntary bladder muscle contractions that often times a patient cannot suppress, resulting in involuntary loss of urine. OAB can force patients to limit their participation in a myriad of physical and social activities, leaving sufferers feeling frustrated, anxious, embarrassed and sleep deprived.
