In patients with CrCl 10 to 30 mL/min, immediate-release tolterodine and metabolite levels were 2- to 3-fold higher compared with healthy patients. ER tolterodine has not been studied in patients with CrCl less than 10 mL/min.
The elimination half-life of immediate-release tolterodine was longer and Cl was substantially lower in cirrhotic patients compared with healthy patients.
Serum concentrations of immediate-release tolterodine and 5-HMT were 20% to 50% higher in elderly patients.
Concerns related to adverse effects:
- Angioedema: Cases of angioedema have been reported; some cases have occurred after a single dose. Discontinue immediately if angioedema and associated difficulty breathing, airway obstruction, or hypotension develop.
- CNS effects: May cause drowsiness, dizziness, and/or blurred vision, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving). Dose reduction or discontinuation should be considered if CNS effects occur.
- QT prolongation: Has been associated with QTc prolongation at high (supratherapeutic) doses. The manufacturer recommends caution in patients with congenital prolonged QT or in patients receiving concurrent therapy with QTc-prolonging drugs (class Ia or III antiarrhythmics). However, the extent of QTc prolongation even at supratherapeutic dosages was less than 15 msec. Individuals who are CYP2D6 poor metabolizers or in the presence of inhibitors of CYP2D6 and CYP3A4 may be more likely to exhibit prolongation.
Disease-related concerns:
- Bladder flow obstruction: Use with caution in patients with bladder flow obstruction; may increase the risk of urinary retention.
- Gastrointestinal obstructive disorders: Use with caution in patients with decreased GI motility or gastrointestinal obstructive disorders (ie, pyloric stenosis); may increase the risk of gastric retention.
- Glaucoma: Use with caution in patients with controlled (treated) narrow-angle glaucoma.
- Hepatic impairment: Use with caution in patients with hepatic impairment; dosage adjustment is required.
- Myasthenia gravis: Use with caution in patients with myasthenia gravis.
- Renal impairment: Use with caution in patients with renal impairment; dosage adjustment is required.
Concurrent drug therapy issues:
- CYP3A4 inhibitors: Dosage adjustment is recommended in patients receiving CYP3A4 inhibitors; a lower dose of tolterodine is recommended.

Teratogenic effects were observed in some animal reproduction studies.
Tolterodine is a competitive antagonist of muscarinic receptors. In animal models, tolterodine demonstrates selectivity for urinary bladder receptors over salivary receptors. Urinary bladder contraction is mediated by muscarinic receptors. Tolterodine increases residual urine volume and decreases detrusor muscle pressure.

- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
- Patient may experience fatigue, headache, blurred vision, abdominal pain, heartburn, constipation, dry mouth, or dry eyes. Have patient report immediately to prescriber shortness of breath, severe dizziness, passing out, confusion, urinary retention, or painful urination (HCAHPS).
- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
