Used primarily to treat overactive bladder (OAB) symptoms such as frequent urination, urgent need to urinate, and urinary incontinence. It works by relaxing the bladder muscles, helping to control involuntary contractions that lead to leakage or sudden urges. Commonly prescribed for adults, it improves bladder capacity and reduces episodes of incontinence, enhancing quality of life. Available in immediate-release and extended-release forms for flexible dosing.
