FDA Approves Watson's OXYTROL(TM), The First and Only Transdermal Therapy for Overactive Bladder
Wednesday February 26, 9:34 pm ET


CORONA, Calif., Feb. 26 /PRNewswire-FirstCall/ -- Watson Pharmaceuticals, Inc. (NYSE: WPI - News), 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(TM) 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(TM) innovative transdermal delivery will provide OAB sufferers with a much needed treatment option. In addition, OXYTROL's(TM) 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(TM) provides effective control of OAB symptoms over a three to four day period. Data also show that OXYTROL(TM) is well tolerated, with anticholinergic side effects, such as dry mouth and constipation, comparable to placebo. The most common adverse events occurring with OXYTROL(TM) 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(TM) study investigator. "OXYTROL's(TM) 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(TM) is a thin, flexible and clear patch that should be applied to the abdomen, hip or buttock twice weekly. The active ingredient in OXYTROL(TM) is oxybutynin, a medication widely accepted and prescribed in oral formulation for the past 25 years. OXYTROL's(TM) 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(TM) should not use OXYTROL(TM).

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.

For full prescribing information on OXYTROL(TM), please call 1-888-OXYTROL (1-888-699-8765).

Has anyone tried this patch in one of the trials? I have an appointment with my urologist on Monday and wanted to see if this might be a better option? Oral diropan dries me out so much and makes the BP hard.

Carl - Are you going to see Dr. DelTerzo? If so, I'd be interested in his response.

Action is the catalyst of true destiny - Imagine the future - Then get to work on it.

3.9 mg a day?? I'd have to wear 5 patches to match the 20mg of Ditropan XL. Anyone know what the target group was for the trial? I mean anyone with a CNS disorder or just dribblers from prostate surgery, childbirth, etc.?

I spoke with my urologist, Dr.DelTerzo at Tirr today about the patch. He had heard of trials, but did not know that it had been approved. He was very open to the idea of delivering the medication this way, and was going to call phone number in the press release to see if it was immediately available. He did mention that because spinal cord patients usually are on a higher dose, that it may still have to be combined with the oral medication but at a lower dose orally.

Sue, I take 10 mg ditropan xl at present but I wonder if because the medication is not being filtered through the stomach and liver, if it could be taken at a lower dose more directly like the patch and still have the same effect. I did not ask my urologist about that. Hell, I would be more than happy to wear a couple of patches just to be able to get some taste back in the food I eat. The ditropan just makes everything tastes like dirt. http://sci.rutgers.edu/forum/images/smilies/smile.gif

Floyd - You have said that you are having major bladder spasms with your "new silicon catheter" . Is the catheter causing the spasms? What were your other catheters made of? Are you possibly allergic or sensitive to the silicon? Have you discussed the problem with your urologist? If not, I would urge you to talk with so the problem can be resolved. CRF

i had to change to silicon because i had become allergic to latex, theres a cyst like thing next to my catheter from the latex but the silicon really makes my bladder spasm. my consultant told me to try 5mg ditropan 3x a day so when i try again with the silicon cath ill be giving this a try? at the moment im back with the latex because of the spasms the silicon gave me.

Normally I'd be happy to join you Carl. My food tastes ok but if I don't drink a lot when eating I get the worst hiccups. I mean they hurt!

I'm not sure the patch would be an improvement over XL oral though. I mean XL works because each tablet has a microscopic hole drilled in it by a laser. Stomach acids slowly carve out the drug through that hole and leave the tablet to pass on through the digestive system. Seems to me that drug going through the skin to the blood and filtered by the kidneys isn't much different than what oral XL does by being absorbed through the intestinal wall, into the blood stream and filtered by the kidneys.

I guess I need to reread the PDR on this because I didn't realize the liver was involved with the oral med. But there has to be a better way to deal with spasms. Ditropan also does a number on your tooth enamel from the dry mouth. Grrrrr

I started using the Oxytrol patch one week ago.
During the 6 years I used Ditropan/Detrol I experienced a lot of trouble with sensitive teeth & loss of enamel (so much dental work! arrgh!). I also just hated the dry mouth for the social rammifications of it.

Anyhow, so far the situation in my mouth has improved a lot. On Wednesday I started using regular toothpaste (as opposed to sensitive teeth toothpaste) and have had no problems. I actually managed to suck on an ice cube today without having horrible pain!

As far as my bladder, the medication seems to be getting there just fine & helping as much as my 10mg of DitropanXL (daily) did. I used two patches this week (on a 3 day, 4 day cycle) but we're going to try just changing every 3 days, because on the 4th day I definitely noticed more problems (leaking).

If anyone is interested in hearing more, I will continue to post progress! Let me know. http://sci.rutgers.edu/forum/images/smilies/smile.gif

Carl R & Everyone,
I have been using patch since June 19,03 right after bladder infection. Was on 40mg Ditropan with extreme side effects, and still leaking a little. Now 2mo post June, experience burning when time to cath and still leaking,but side effects have improved greatly. Going to call Dr. this week for review. I use 1, 3.9mg patch every 4 days. Hoping things get better.

I am curious to find out if you guys have had any skin problems or break down related to the placement of the patch?

Carl R - Skin irritation can be a side effect of using a transdermal patch. In studies with this particular med, there were reports of mild skin irritation. If you are having problems with this, I would urge you to discuss this with your doctor.

It is important to rotate sights and location of placement within each site. It your are having sensitivity problems, you might note whether one location is more sensitive than another...then avoid using that particular one. Nevertheless, it still warrants a call to your doctor. CRF

I haven't had any skin irritation, yet. I have been rotating around the approved sites, each side of my hip & on either side of my abdomen. I do notice some discomfort when I remove the patches, and learning how to apply them correctly does take a few tries (by my third patch I was okay). The discomfort comes from those little teeny hairs on skin, they get pulled right off with the patch. Ouch! So far, for me it's been worth it to decrease the side effects so much. =)

Anyone have any info on it's availibility in Canada?
I'm on 5mg a day and this sounds like something worth trying.

Re: irritation of the skin with transdermal patches, some people have more sensitive skin than others. For some it could be the patch material, for others a sensitivity to the medication. This is all very individualized and each person must be the judge of what works for oneself. CRF

Nate 007 - I would suggest that you call the number listed within this article and inquire about the availability in Canada. CRF
