New drug treats overactive bladder without drying mouth

Overactive bladder (OAB) affects approximately 17 million to 20 million people in the United States, yet few realize that it is a treatable condition. Many people believe that it is a natural part of the aging process and are embarrassed to discuss it. It is estimated that costs related to OAB were nearly $14 billion in this country in 2000, similar to that of gynecological and breast cancers, osteoporosis, or arthritis.
