2001 MAY 24 - (NewsRx Network) -- Results of a Phase IV clinical study evaluating the two leading medications for the treatment of overactive bladder were presented at the American College of Obstetricians and Gynecologists' (ACOG) 50th Annual Clinical Meeting.
The findings of the "Overactive Bladder: Judging Effective Control and Treatment" (OBJECT) study showed that patients suffering from overactive bladder experienced a significant reduction in symptoms, including the most troublesome - urge incontinence - when treated with extended-release oxybutynin chloride (Ditropan [XL.sup.R]) as compared to patients treated with tolterodine tartrate ([Detrol.sup.R]).
"The OBJECT study was a very well-designed investigation comparing the two drugs that are most widely prescribed in the United States for patients suffering from symptoms of overactive bladder," said presenter and study investigator Peter K. Sand, MD, director, Evanston Continence Center at Evanston Northwestern Healthcare and associate professor, Northwestern University Medical School, Illinois. "The results demonstrated superior efficacy with Ditropan XL in treating the problems associated with an overactive bladder, providing physicians with valuable knowledge in treating patients with the most effective medication available."
Overactive bladder affects approximately 17 million Americans, making it more prevalent than many commonly discussed conditions, such as diabetes (seven million) and Alzheimer's disease (four million). With symptoms of urinary urge incontinence, involuntary loss of bladder control; urgency, urgent need to urinate; and urinating more than eight times a day (micturition frequency), overactive bladder is one of the most under-diagnosed and under-treated conditions in the United States. In fact, fewer than 20% of sufferers actually talk to their physician about symptoms.
OBJECT is the first study to compare the efficacy and tolerability of Ditropan XL and Detrol. Study results showed statistically significant reductions in the number of urge and total incontinence episodes and in micturition frequency from baseline in both treatment groups (p[less than]0.001). Ditropan XL proved to be significantly more effective than Detrol in all study end points: urge incontinence (p=0.031), ...
