In patients with severe renal function impairment, there is a 4.5- and 2-fold increase in mean AUC and Cmax, respectively, and prolonged elimination t ‚ ½.
In patients with with severe renal function impairment, there is a 4.2- and 1.8-fold increase in mean AUC and Cmax, respectively, and prolonged elimination half-life.
In patients with mild or moderate hepatic impairment, the Cmax increased 12% and 63%, respectively (immediate release).
Pharmacokinetic data are conflicting. Exposure was 45% lower in elderly women compared with elderly men when a single 40 mg immediate-release dose was administered. AUC and Cmax were 26% and 68% higher, respectively, in women without hormone replacement therapy compared with men.
Concerns related to adverse effects:
- Angioedema: Cases of angioedema involving the face, lips, tongue, and/or larynx have been reported. Immediately discontinue if tongue, hypopharynx, or larynx are involved.
- CNS effects: May cause drowsiness, confusion, dizziness, hallucinations, 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).
Disease-related concerns:
- Alzheimers disease: Use with caution in patients with Alzheimer's disease.
- 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 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 moderate or severe hepatic impairment.
- Myasthenia gravis: Use with caution in patients with myasthenia gravis due to decreased GI motility.
- Renal impairment: Use immediate release formulation with caution in patients with renal impairment; dosage adjustment is required. Use of the extended release formulation is contraindicated in patients with severe renal impairment (CrCl <30 mL/minute).
- Ulcerative colitis: Use with caution in patients with ulcerative colitis due to decreased GI motility.
Concurrent drug therapy issues:
- Medications eliminated by active tubular secretion (ATS): ATS is a route of elimination; use caution with other medications that are eliminated by ATS (eg, procainamide, pancuronium, vancomycin, morphine, metformin, and tenofovir).
- Sedatives: Effects with other sedative drugs or ethanol may be potentiated.
Dosage form specific issues:
- Extended release: Ethanol should not be ingested within 2 hours of the administration of the extended release formulation; may increase incidence of drowsiness.

Adverse events were observed in animal studies. There are no adequate or well-controlled studies in pregnant women; use only if clearly needed.
Trospium antagonizes the effects of acetylcholine on muscarinic receptors in cholinergically innervated organs. It reduces the smooth muscle tone of the bladder.

- 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 constipation, dry mouth, blurred vision, or fatigue. Have patient report immediately to prescriber severe dizziness, passing out, lack of sweat, confusion, hallucinations, 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.
