Overview
DETRUSITOL SR 2mg is a prescription medication designed for the treatment of overactive bladder with symptoms of urinary frequency, urgency, and incontinence. The active ingredient, Tolterodine, is an antimuscarinic agent that helps to relax the bladder muscles, thereby reducing bladder spasms.
Indications
- Overactive Bladder: DETRUSITOL SR is indicated for patients experiencing frequent urination, urgency to urinate, and urinary incontinence.
Mechanism of Action
Tolterodine works by blocking muscarinic receptors in the bladder. This inhibition reduces involuntary bladder contractions and increases bladder capacity, leading to a decrease in the urgency and frequency of urination.
Dosage and Administration
- Recommended Dose: The typical dosage for adults is one 2mg extended-release capsule taken once daily.
- Administration: Capsules should be taken whole with water, and can be taken with or without food. Do not crush or chew the capsules.
