Tablets: 20 mg

Indications and dosages

Overactive bladder with symptoms of urge urinary incontinence, urgency, and urinary frequency

Adults: 20 mg P.O. twice daily 1 hour before meals or on empty stomach, or 1 60-mg capsule daily in morning with water at least 1 hour before a meal

Dosage adjustment

• Severe renal impairment

• Patients age 75 and older


• Hypersensitivity to drug or its components

• Preexisting or risk of urinary or gastric retention or uncontrolled angle-closure glaucoma


Use cautiously in:

• moderate renal impairment, moderate to severe hepatic impairment, decreased GI motility, controlled angle-closure glaucoma, clinically significant bladder outflow obstruction or GI obstructive disorders

• patients at risk for heat prostration

• elderly patients

• pregnant or breastfeeding patients

• children (safety and efficacy not established).


• Give at least 1 hour before meals or on empty stomach.

Adverse reactions

CNS: headache, fatigue, syncope, hallucinations, delirium, dizziness, drowsiness

CV: tachycardia, chest pain

EENT: dry eyes, blurred vision, dry throat

GI: vomiting, constipation (new-onset or aggravated), upper abdominal pain, dyspepsia, flatulence, abdominal distention, dry mouth

GU: urinary retention

Skin: dry skin

Other: altered taste, heat prostration, angioedema


Drug-drug. Anticholinergics: additive anticholinergic effects

Digoxin, metformin, morphine, pancuronium, procainamide, tenofovir, vancomycin: increased blood levels of both drugs

Drug-behaviors. Alcohol use: increased risk of drowsiness

Patient monitoring

• Monitor renal and hepatic function tests.

• Monitor patient for decreased GI motility and urinary retention.

If patient has controlled angle-closure glaucoma, stay alert for severe eye pain accompanied by nausea, rainbows around lights, red eye, and blurred vision. Be prepared to treat immediately, as appropriate.

Be aware that angioedema associated with life-threatening upper airway swelling may occur. If involvement of the tongue, hypopharynx, or larynx occurs, promptly discontinue drug and provide appropriate treatment.

Patient teaching

• Instruct patient to take tablet 1 hour before meals on an empty stomach or to take capsule in morning with water at least 1 hour before a meal.

• Instruct patient not to consume alcohol within 2 hours of taking extended-release capsule.

• Advise patient to consult prescriber before taking over-the-counter products such as antihistamines because these may increase risk of side effects.

• Inform patient that drug increases risk of heat prostration; describe symptoms and advise him to seek prompt medical attention if these occur.

• Caution patient to avoid driving and other hazardous activities until drug effects are known.

• Advise patient to avoid alcohol use.

• As appropriate, review all other significant adverse reactions and interactions, especially those related to the drugs and behaviors mentioned above.

Therapeutic: urinary tract antispasmodics
Pharmacologic: antimuscarinics
Pregnancy Category: C


Overactive bladder with symptoms of urge urinary incontinence, urgency and urinary frequency.


Antagonizes the effect of acetylcholine at muscarinic receptors in the bladder; this parasympatholytic action reduces bladder smooth muscle tone.

Therapeutic effects

Increased bladder capacity and decreased symptoms of overactive bladder.


Absorption: Less than 10% absorbed following oral administration; food significantly ↓ absorption.
Distribution: Mostly distributed to plasma.
Metabolism and Excretion: Of the 10% absorbed, 40% is metabolized. Unabsorbed drug is mainly excreted in feces. Of absorbed drug, 60% is eliminated in urine as unchanged drug via active tubular secretion.
Half-life: 20 hr.

Time/action profile (anticholinergic effects)

POunknown5–6 hr24 hr


Contraindicated in: Hypersensitivity;Gastric or urinary retention, uncontrolled angle-closure glaucoma or risk for these conditions.
Use Cautiously in: Bladder outflow obstruction;Gastrointestinal obstructive disorders (ulcerative colitis, intestinal atony, myasthenia gravis);Controlled angle-closure glaucoma (use only if necessary and with careful monitoring);CCr <30 mL/min (dose ↓ recommended);Moderate to severe hepatic impairment; Obstetric / Lactation: Use only if benefit justifies risks to fetus/newborn; Pediatric: Safety not established; Geriatric: May have↑ sensitivity to anticholinergic effects; ↓ dose may be required.

Adverse Reactions/Side Effects

Central nervous system

  • headache (most frequent)
  • confusion
  • dizziness
  • drowsiness
  • fatigue
  • hallucinations

Ear, Eye, Nose, Throat

  • blurred vision


  • constipation (most frequent)
  • dry mouth (most frequent)
  • dyspepsia


  • urinary retention
  • urinary tract infection


  • angioedema (life-threatening)
  • fever
  • heat stroke


Drug-Drug interaction

May interact with other drugs that compete for tubular secretion.Metformin may ↓ levels.↑ risk of anticholinergic effects with other drugs having anticholinergic properties.


Oral (Adults) 20 mg twice daily or 60 mg once daily (XR dose form).
Oral (Adults ≥75 yr) Based on tolerability, dose may be ↓ to 20 mg once daily.

Renal Impairment

Oral (Adults) CCr <30 mL/min—20 mg once daily at bedtime.

Availability (generic available)

Tablets: 20 mg
Extended release tablets: 60 mg

Nursing implications

Nursing assessment

  • Monitor voiding pattern and intake and output ratios.

Potential Nursing Diagnoses

Impaired urinary elimination (Indications)


  • Oral: Administer 1 hr prior to meals or on an empty stomach.

Patient/Family Teaching

  • Instruct patient to take as directed. If a dose is skipped, take next dose 1 hr prior to next meal.
  • May cause drowsiness, dizziness, and blurred vision. Caution patient to avoid driving and other activities requiring alertness until response to medication is known. Advise patient to avoid alcohol; may increase drowsiness.
  • Advise patient to notify health care professional immediately of signs and symptoms of angioedema (edema of the tongue or laryngopharynx, difficulty breathing) occur.
  • Caution patient that heat prostration (fever and heat stroke due to decreased sweating) may occur when trospium is taken in a hot environment.
  • Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and consult health care professional before taking any new medications.
  • Advise female patient to notify health care professional if pregnancy is planned or suspected, or if breast feeding.

Evaluation/Desired Outcomes

  • Increased bladder capacity and decreased symptoms of overactive bladder.

The company's marketed products include SANCTURA for overactive bladder and DELATESTRYL to treat male hypogonadism.
Sanctura must be taken on an empty stomach, twice a day, while Vesicare does not, is longer acting, and is taken once a day.
According to the company, the Trospium Chloride Extended-release Capsules is the generic equivalent to Allergan's Sanctura XR, which is indicated for the treatment of overactive bladder (OAB) with symptoms of urge urinary incontinence, urgency and urinary frequency.
In addition to Sanctura and oxybutynin--available as Ditropan and in generic formulations and as extended release oxybutynin (Ditropan XL)--the other anticholinergics approved for OAB are regular and long-acting tolterodine (Detrol and Detrol LA) and the oxybutynin transdermal patch (Oxytrol).
