Tolterodine

Published: July 26, 2026Updated: July 26, 2026

Tolterodine is an antimuscarinic medication used to treat overactive bladder, helping to reduce urinary urgency, frequency, and incontinence episodes. It works by blocking muscarinic receptors in the bladder wall, preventing involuntary muscle contractions that cause the urge to urinate.

Primary pharmacological mechanism

Tolterodine is used to treat overactive bladder with symptoms of urinary urgency, frequency, and urge incontinence. It helps control involuntary bladder contractions that cause sudden urges to urinate and accidental leakage.

Tolterodine is a competitive antagonist at muscarinic acetylcholine receptors. By blocking these receptors in the urinary bladder detrusor muscle, it inhibits involuntary contractions, increases bladder capacity, and reduces urgency sensations.

Common side effects include dry mouth, constipation, and blurred vision due to anticholinergic effects. It should be used cautiously in patients with urinary retention, narrow-angle glaucoma, or myasthenia gravis. Liver metabolism may interact with other medications metabolized by CYP450 enzymes.
