Dosage Forms

Excipient information presented when available (limited, particularly for generics); consult specific product labeling.

Capsule, Oral, as hydrochloride:

Evoxac: 30 mg

Generic: 30 mg


Mechanism of Action

Binds to muscarinic (cholinergic) receptors, causing an increase in secretion of exocrine glands (such as salivary and sweat glands) and increase tone of smooth muscle in gastrointestinal and urinary tracts



Rapid; food decreases rate of absorption


Vd: 6 L/kg


Hepatic via CYP2D6, CYP3A3, and CYP3A4; metabolites: cis and trans-sulfoxide, glucuronic acid conjugate, N-oxide metabolite


Urine (84% in 24 hours, 97% in 7 days); feces (0.5% in 7 days)

Time to Peak

1.5 to 2 hours

Half-Life Elimination

5 ± 1 hours

Protein Binding


Use: Labeled Indications

Xerostomia (associated with Sjögren's syndrome): Treatment of symptoms of dry mouth in patients with Sjögren's syndrome.


Hypersensitivity to cevimeline or any component of the formulation; uncontrolled asthma; when miosis is undesirable (eg, narrow-angle glaucoma, acute iritis)

Dosage and Administration

Dosing: Adult

Xerostomia (associated with Sjögren's syndrome): Oral: 30 mg 3 times/day

Dosing: Geriatric

Refer to adult dosing.


Store at 25°C (77°F); excursions permitted to 15°C to 30°C (59°F to 86°F).

Drug Interactions

Acetylcholinesterase Inhibitors: May enhance the adverse/toxic effect of Cholinergic Agonists. Monitor therapy

Beta-Blockers: May enhance the adverse/toxic effect of Cholinergic Agonists. Of particular concern are the potential for cardiac conduction abnormalities and bronchoconstriction. Monitor therapy

Cimetropium: Cholinergic Agonists may diminish the anticholinergic effect of Cimetropium. Monitor therapy

Sincalide: Drugs that Affect Gallbladder Function may diminish the therapeutic effect of Sincalide. Management: Consider discontinuing drugs that may affect gallbladder motility prior to the use of sincalide to stimulate gallbladder contraction. Consider therapy modification

Concerns related to adverse effects:

  • Parasympathomimetic effects: Toxicity is characterized by an exaggeration of parasympathomimetic effects (eg, atrioventricular block, bradycardia, cardiac arrhythmia, hypotension, lacrimation, sweating, respiratory distress, tachycardia, tremors, vomiting); excessive sweating may lead to dehydration in some patients.
  • Visual effects: May cause blurred vision, decreased visual acuity (particularly at night and in patients with central lens changes) and impaired depth perception. Patients should be cautioned about driving at night or performing hazardous activities in reduced lighting.

Disease-related concerns:

  • Cardiovascular disease: Use with caution in patients with significant cardiovascular disease (including angina, myocardial infarction); may alter cardiac conduction and/or heart rate.
  • Cholelithiasis: Use with caution in patients with a history of cholelithiasis; may induce contractions of the gallbladder or biliary smooth muscle, precipitating complications such as cholangitis, cholecystitis, or biliary obstruction.
  • Nephrolithiasis: Use with caution in patients with a history of nephrolithiasis; may induce smooth muscle spasms, precipitating renal colic or ureteral reflux in patients with nephrolithiasis.
  • Respiratory disease: Use with caution in patients with controlled asthma, COPD, or chronic bronchitis; may increase bronchial smooth muscle tone, airway resistance, and bronchial secretions.

Special populations:

  • Patients with CYP2D6 deficiency: Patients with a known or suspected deficiency of CYP2D6 may be at higher risk of adverse effects.


Pregnancy Considerations

Adverse effects were observed in animal reproduction studies.
