Tolterodine Information
Tolterodine is an antimuscarinic agent that targets the bladder’s detrusor muscle to relieve symptoms of overactive bladder (OAB). Belonging to the muscarinic receptor antagonist class, it reduces involuntary contractions that cause urgency, frequency, and urge incontinence. Widely marketed under the brand name Detrol and available in extended-release formulations, tolterodine is approved for adult use in Singapore and many other jurisdictions. While its primary indication is OAB, clinicians occasionally consider it for related storage-phase disorders, though such off-label applications remain uncommon. Understanding its mechanism of action, dosing options, and safety profile helps patients make informed choices when they decide to buy tolterodine online through reputable channels.
What is Tolterodine?
Tolterodine belongs to the antimuscarinic (muscarinic receptor antagonist) class, selectively blocking M2 and M3 receptors in the urinary tract. The Health Sciences Authority (HSA) in Singapore granted market approval in 2001, following earlier approval by the U.S. Food and Drug Administration (FDA) in 1998 for treating OAB. Its core molecular action involves preventing acetylcholine from binding to bladder smooth-muscle receptors, thereby decreasing involuntary detrusor contractions. The drug is distributed worldwide as the brand Detrol (immediate-release) and Detrol XR (extended-release), as well as generic tolterodine tartrate tablets, all of which can be ordered from our online pharmacy.
How Tolterodine Works
Mechanism of Action
Tolterodine competitively inhibits muscarinic M2 and M3 receptors on the detrusor muscle. By reducing intracellular calcium release, it dampens the contractile response to acetylcholine. This inhibition is relatively bladder-selective, sparing other smooth-muscle sites and minimizing systemic anticholinergic effects compared with less selective agents.
Therapeutic Effects
The blockade of M3 receptors curtails the force and frequency of involuntary bladder contractions. Patients therefore experience fewer urgency episodes, reduced nocturia, and a lower likelihood of accidental leakage. The drug’s ability to restore a more normal voiding pattern improves quality of life, especially in individuals whose daily activities are disrupted by OAB symptoms.
Onset and Duration
Clinical trials report that symptom improvement can be detected within 3 to 5 days of initiating therapy, with maximal benefit usually reached after 4 weeks of consistent dosing. The immediate-release formulation has a half-life of approximately 2 hours, requiring twice-daily administration, whereas the extended-release tablet maintains therapeutic plasma concentrations for about 24 hours, supporting once-daily dosing.
Approved Uses and Applications
Approved Indications
- Overactive bladder with urgency urinary incontinence - reduces episodes of leakage and urgency.
- Urgency and frequency - alleviates the need to void repeatedly during the day.
- Nocturia associated with OAB - lowers nighttime voids, improving sleep continuity.
These indications are endorsed by the HSA, FDA, and the European Medicines Agency (EMA).
Off-Label Uses
Limited evidence supports tolterodine for neurogenic detrusor overactivity in patients with spinal cord injury, though regulatory agencies have not formally approved this indication. Clinicians occasionally prescribe it for mixed incontinence when other agents are ineffective, but such use remains off-label.
Clinical Efficacy
In a double-blind, placebo-controlled trial published in The New England Journal of Medicine, 63 % of participants receiving tolterodine experienced at least a 50 % reduction in urgency episodes compared with 31 % on placebo (p < .001). Another study in The Lancet demonstrated a mean decrease of 2.3 voids per day after 12 weeks of therapy, confirming its robust symptom-control profile.
Buying Tolterodine from Our Online Pharmacy

Dosing, Formulations & Administration
Available Formulations
Tolterodine is offered as oral tablets in immediate-release (2 mg) and extended-release (2 mg, 4 mg) strengths. Liquid formulations are not commercially available in Singapore.
Typical Dosing Ranges
For adults with OAB, clinicians often start with tolterodine 2 mg twice daily (immediate-release) or 2 mg once daily (extended-release). Dose escalation to 4 mg daily may be considered if symptom control remains inadequate and tolerability is acceptable.
Administration Guidelines
- Food: The extended-release tablet can be taken with or without food; taking it with a meal may reduce gastrointestinal discomfort.
- Timing: Consistency matters; patients should aim to ingest the dose at the same time each day to maintain steady plasma levels.
- Swallowing: Tablets should be swallowed whole; crushing or chewing may alter release characteristics.
A qualified healthcare provider must determine the exact regimen based on individual health status, concomitant medications, and response to therapy.
Safety Profile & Considerations
Common Side Effects
- Dry mouth (occurs in > 10 % of users) - may be mitigated by sipping water regularly.
- Constipation (≈ 8 % incidence) - dietary fiber and adequate hydration help reduce severity.
- Blurred vision (≈ 5 % incidence) - usually transient, but patients should avoid operating heavy machinery if vision is affected.
Serious Adverse Events
- Urinary retention - rare but requires immediate medical evaluation if patients experience difficulty initiating urination.
- Elevated intra-ocular pressure - patients with glaucoma risk should be monitored closely.
Contraindications
- Known hypersensitivity to tolterodine or any excipients.
- Severe uncontrolled narrow-angle glaucoma.
- Acute urinary retention or obstructive uropathy.
Drug Interactions
- CYP2D6 inhibitors (e.g., fluoxetine, paroxetine) can raise tolterodine plasma levels, increasing anticholinergic burden.
- Other anticholinergics (e.g., diphenhydramine) may potentiate dry mouth and constipation.
- Beta-blockers - concurrent use may blunt the therapeutic effect on detrusor muscle.
Special Populations
- Pregnancy & breastfeeding: Safety data are limited; the drug is typically avoided unless benefits outweigh risks.
- Elderly: Age-related decline in renal function can amplify anticholinergic side effects; starting at the lowest dose is prudent.
- Renal/hepatic impairment: Dose adjustment may be required for severe impairment, guided by clinical monitoring.
Frequently Asked Questions
-
How does tolterodine differ from oxybutynin? Tolterodine offers greater bladder selectivity and a lower incidence of dry mouth compared with oxybutynin, which is a less selective antimuscarinic.
-
How long before tolterodine produces noticeable effects for overactive bladder? Patients typically report improvement within the first week, with full therapeutic benefit emerging after four weeks of consistent use.
