Detrusitol (Tolterodine) is a medication used to treat an overactive bladder, a condition characterized by symptoms such as frequent urination, urgency, and incontinence. It works by relaxing the bladder muscles, reducing spasms, and increasing the bladder's storage capacity. This helps control urinary urgency and frequency, improving quality of life. Detrusitol is available in extended-release capsules for once-daily dosing, providing consistent symptom relief. It is important to follow your doctor's prescribed dosage to achieve optimal results.
