( 5.1 , 5.3 ) • Angioedema of the face, lips, tongue and/or larynx has been reported with trospium chloride. ( 5.2 ) • In patients with narrow angle glaucoma, Trospium Chloride Extended-Release Capsules should be used only with careful monitoring. ( 5.4 ) • Central Nervous System Effects: Somnolence has been reported with Trospium Chloride Extended-Release Capsules. Advise patients not to drive or operate heavy machinery until they know how Trospium Chloride Extended-Release Capsules affects them. ( 5.5 ) • Trospium Chloride Extended-Release Capsules are not recommended for use in patients with severe renal impairment (creatinine clearance less than 30 mL/minute). ( 5.6 ) • Alcohol should not be consumed within 2 hours of Trospium Chloride Extended-Release Capsules administration. ( 5.7 ) 5.1 Risk of Urinary Retention Trospium Chloride Extended-Release Capsules should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention [ see Contraindications (4) ]. 5.2 Angioedema Angioedema of the face, lips, tongue and/or larynx has been reported with trospium chloride. In one case, angioedema occurred after the first dose of trospium chloride. Angioedema associated with upper airway swelling may be life threatening. If involvement of the tongue, hypopharynx, or larynx occurs, trospium chloride should be promptly discontinued and appropriate therapy and/or measures necessary to ensure a patent airway should be promptly provided. 5.3 Decreased Gastrointestinal Motility Trospium Chloride Extended-Release Capsules should be administered with caution to patients with gastrointestinal obstructive disorders because of the risk of gastric retention [ see Contraindications (4) ]. Trospium Chloride Extended-Release Capsules, like other antimuscarinic agents, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as ulcerative colitis, intestinal atony and myasthenia gravis. 5.4 Controlled Narrow-angle Glaucoma In patients being treated for narrow-angle glaucoma,Trospium Chloride Extended-Release Capsules should only be used if the potential benefits outweigh the risks, and in that circumstance only with careful monitoring [see Contraindications (4 ) ]. 5.5 Central Nervous System Effects Trospium Chloride Extended-Release Capsules and Trospium Chloride Immediate Release Capsules are associated with anticholinergic central nervous system (CNS) effects [see Adverse Reactions (6.2 ) ]. A variety of CNS anticholinergic effects have been reported, including dizziness, confusion, hallucinations and somnolence. Patients should be monitored for signs of anticholinergic CNS effects, particularly after beginning treatment or increasing the dose. Advise patients not to drive or operate heavy machinery until they know how Trospium Chloride Extended-Release Capsules affects them. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. 5.6 Patients with Severe Renal Impairment Trospium Chloride Extended-Release Capsules are not recommended for use in patients with severe renal impairment (creatinine clearance less than 30 mL/minute) [see Dosage and Administration (2) , Use in Specific Populations (8.6), and Clinical Pharmacology (12.3 ) ]. 5.7 Alcohol Interaction Alcohol should not be consumed within 2 hours of Trospium Chloride Extended-Release Capsules administration. In addition, patients should be informed that alcohol may enhance the drowsiness caused by anticholinergic agents.

Interactions

Trospium is metabolized by ester hydrolysis and excreted by the kidneys through a combination of tubular secretion and glomerular filtration. Based on in vitro data, no clinically relevant metabolic drug-drug interactions are anticipated with Trospium Chloride Extended-Release Capsules. However, some drugs which are actively secreted by the kidney may interact with Trospium Chloride Extended-Release Capsules by competing for renal tubular secretion. The concomitant use of Trospium Chloride Extended-Release Capsules with other antimuscarinic agents that produce dry mouth, constipation, and other anticholinergic effects may increase the frequency and/or severity of such effects. Trospium Chloride Extended-Release Capsules may potentially alter the absorption of some concomitantly administered drugs due to anticholinergic effects on gastrointestinal motility. • Some drugs which are actively secreted by the kidney may interact with Trospium Chloride Extended-Release Capsules by competing for renal tubular secretion. ( 7 ) • Concomitant use with digoxin did not affect the pharmacokinetics of either drug. ( 7.1 ) • Exposure to trospium on average was comparable in the presence of and without antacid, however, some individuals demonstrated increases or decreases in trospium exposure in the presence of antacid. The clinical relevance of these findings is not known. ( 7.2 ) • Concomitant use with metformin immediate release tablets reduced exposure and peak concentration of trospium. ( 7.3 ) 7.1 Digoxin Concomitant use of trospium chloride 20mg twice daily and digoxin did not affect the pharmacokinetics of either drug [see Clinical Pharmacology (12.3 ) ]. 7.2 Antacid While the systemic exposure of trospium on average was comparable with and without antacid containing aluminum hydroxide and magnesium carbonate, 5 out of 11 individuals in a drug interaction study demonstrated either an increase or decrease in trospium exposure, in presence of antacid. The clinical relevance of these findings is not known [see Clinical Pharmacology (12.3) ]. 7.3 Metformin Co-administration of 500 mg metformin immediate release tablets twice daily reduced the steady-state systemic exposure of trospium by approximately 29% for mean AUC (0-24) and by 34% for mean C max . The effect of a decrease in trospium exposure on the efficacy of Trospium Chloride Extended-Release Capsules is unknown. The steady-state pharmacokinetics of metformin were comparable when administered with or without 60 mg Trospium Chloride Extended-Release Capsules once daily under fasted condition. The effect of metformin at higher doses on trospium PK is unknown [ see Clinical Pharmacology (12.3 ) ].

Frequently asked questions

What does Trospium Chloride treat?
Trospium Chloride (Trospium Chloride) may be used to treat overactive urinary bladder, urge urinary incontinence, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
How does Trospium Chloride work?
Trospium Chloride is a cholinergic muscarinic antagonist. These drugs block muscarinic receptors, the docking sites for the nerve signal acetylcholine. By preventing acetylcholine from acting, they calm the 'rest-and-digest' nervous system, which can dry secretions, relax airway and bladder muscles, and speed up the heart, depending on the drug.
How is Trospium Chloride rated?
pharmaranks gives Trospium Chloride a composite score of 3.6 out of 5, currently based on 1 weighted source (FDA regulatory recall-safety data weighted highest). See our methodology at /how-we-rate.
How much does Trospium Chloride cost?
Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $7.08 for 30, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins. Pharmacies pay less for a same-class option, Oxytrol — about $1.42 on the same basis.
