Used primarily as an antispasmodic agent to treat overactive bladder (OAB) symptoms, such as frequent urination, urgency, and incontinence. It works by relaxing the bladder muscles, reducing involuntary contractions, and increasing bladder capacity. Often prescribed for patients with neurogenic detrusor overactivity, a condition associated with spinal cord injuries or neurological disorders. Its dual mechanism of action includes anticholinergic effects and calcium channel blockade, providing effective symptom relief. Typically administered orally in tablet form, with dosage adjusted based on patient response and tolerability. Common side effects include dry mouth, constipation, and blurred vision, which are typical of anticholinergic medications.
