How does this medicine work?

• Trospium chloride is an antispasmodic, antimuscarinic agent.
• Trospium chloride antagonizes the effect of acetylcholine on muscarinic receptors in cholinergically innervated organs including the bladder.

What special precautions should I follow?

• Trospium chloride should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention.
• Angioedema of the face, lips, tongue, and/or larynx has been reported with trospium chloride. Patients should be advised to promptly discontinue trospium chloride tablets and seek immediate medical attention if they experience edema of the tongue, edema of the laryngopharynx, or difficulty breathing.
• Trospium chloride should be administered with caution to patients with gastrointestinal obstructive disorders because of the risk of gastric retention.
• In patients being treated for narrow-angle glaucoma, trospium chloride tablets should only be used if the potential benefits outweigh the risks and in that circumstance only with careful monitoring.
• Trospium chloride is associated with anticholinergic central nervous system (CNS) effects.
• Trospium is substantially excreted by the kidney. Therefore, anticholinergic adverse reactions (including dry mouth, constipation, dyspepsia, urinary tract infection, and urinary retention) are expected to be greater in patients with moderate renal impairment.
• Prior to treatment, patients should fully understand the risks and benefits of trospium chloride tablets. In particular, patients should be informed not to take trospium chloride tablets if they:
• have urinary retention;
• gastric retention;
• uncontrolled narrow-angle glaucoma;
• are allergic to any component of trospium chloride tablets.

• Because anticholinergics, such as trospium chloride tablets, may produce dizziness or blurred vision, patients should be advised to exercise caution in decisions to engage in potentially dangerous activities until the drug’s effects have been determined.
• Patients should be informed that alcohol may enhance the drowsiness caused by anticholinergic agents.
• Alcohol should not be consumed within 2 hours of Trospium Chloride Extended-Release Capsules administration.
• Because many drugs are excreted in human milk, trospium chloride tablets should be used during lactation only if the potential benefit justifies the potential risk to the newborn.
• Trospium has not been implicated in causing liver enzyme elevations or clinically apparent acute liver injury.
