Indications:
Treatment of overactive bladder symptoms: urinary urgency, frequency, and urge incontinence.
Pharmacology:
Tolterodine is a competitive muscarinic receptor antagonist with high selectivity for bladder smooth muscle over salivary glands. Its active metabolite (5‑hydroxymethyl derivative) contributes to the therapeutic effect, typically manifesting within 4 weeks.
Dosage:
Adults: Standard dose is 2 mg twice daily.
If side effects occur, reduce to 1 mg twice daily.
For those with liver/renal impairment or taking potent CYP3A4 inhibitors, limit to 2 mg per day (1 mg b.i.d.).
Re-evaluate use after 6 months.
Administration:
Oral use; swallow whole (do not crush or chew), with or without food.
Interaction:
Potent CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, clarithromycin, itraconazole, ritonavir, cyclosporine, vinblastine) increase Tolterodine levels—adjust dosing accordingly.
No significant interactions with warfarin or hormonal contraceptives.
Caution with QT-prolonging drugs (e.g., Class I A/III antiarrhythmics).
Avoid alcohol—can worsen drowsiness.
Contraindications:
Urinary retention, gastric retention, uncontrolled narrow-angle glaucoma, hypersensitivity to Tolterodine.
Side Effects:
Dry mouth (23–40%), headache, constipation, blurred vision, dizziness, dry eyes, urinary retention, abdominal discomfort.
Pregnancy & Lactation:
Use only if benefits justify risks. No human data—avoid during breastfeeding.
Precautions & Warnings:
Use cautiously in patients with bladder outflow obstruction, GI motility disorders, hepatic or renal impairment, glaucoma, and those taking QT-prolonging drugs. Monitor for drowsiness, blurred vision.
Therapeutic Class:
BPH / Urinary retention / Urinary incontinence (muscarinic receptor antagonist)
