(trade name)

Classification

Therapeutic: xerostomia therapy adjuncts
Pharmacologic: cholinergics
Pregnancy Category: UK

Indications

Treatment of the symptoms of dry mouth associated with Sjögren's syndrome.

Action

Direct cholinergic (muscarinic) effects result on increased secretion of exocrine glands including salivary and sweat glands, and increased smooth muscle tone in the gastrointestinal and urinary tracts.

Therapeutic effects

Improved symptoms of dry mouth in patients with Sjögren's syndrome.

Pharmacokinetics

Absorption: Rapidly absorbed following oral administration.
Distribution: Extensively bound to tissues.
Metabolism and Excretion: genetic implication Mostly metabolized by the liver (CYP2D6 and CYP3A3/4 isoenzymes) (the CYP2D6 enzyme system exhibits genetic polymorphism; ~7% of population may be poor metabolizers and may have significantly ↑ cevimeline concentrations and an ↑ risk of adverse effects); 16% excreted unchanged in urine.
Half-life: 5 hr.

Contraindications/Precautions

Contraindicated in: Hypersensitivity; When miosis is undesirable (acute iritis, angle-closure glaucoma); Lactation: Discontinue or bottle feed.
Use Cautiously in: Cardiovascular disease including angina pectoris or history of MI; Pulmonary disease including asthma, chronic bronchitis, or chronic obstructive pulmonary disease; Nephrolithiasis or cholelithiasis; Geriatric: May be more sensitive to toxicity; Obstetric: Use only if potential benefit justifies potential risk to the fetus; Pediatric: Safety not established.

Adverse Reactions/Side Effects

Central nervous system

  • coughing

Ear, Eye, Nose, Throat

  • rhinitis (most frequent)
  • visual disturbances

Gastrointestinal

  • nausea (most frequent)
  • diarrhea
  • excessive salivation

Dermatologic

  • excessive sweating (most frequent)
  • hot flashes

Interactions

Drug-Drug interaction

Concurrent beta blocker therapy may ↑ the risk of cardiac conduction disturbances.Additive parasympathetic and muscarinic effects may occur with drugs that have parasympathetic or muscarinic properties.Drugs that inhibit CYP2D6 and CYP3A3/4 liver enzymes may inhibit the metabolism of cevimeline and ↑ its effects and risk of toxicity.St. John's wort may ↑ the metabolism of cevimeline and ↓ its levels.Angel's trumpet, jimson weed, and scopolia may antagonize cholinergic effects.

Route/Dosage

Oral (Adults) 30 mg 3 times daily.

Availability (generic available)

Capsules: 30 mg

Nursing implications

Nursing assessment

  • Assess patient for dry mouth prior to and periodically during therapy.
  • Lab Test Considerations: May cause ↑ GGT, AST, and ALT.

Potential Nursing Diagnoses

Impairedoral mucous membrane, altered (Indications)
Deficient knowledge, related to medication regimen (Patient/Family Teaching)

Implementation

  • Oral: Administer 30 mg three times daily.

Patient/Family Teaching

  • Instruct patient to take cevimeline as directed.
  • May cause visual disturbances, especially at night, that could impair ability to drive safely.
  • Advise patient to drink extra water if sweating excessively. May cause dehydration.
  • 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 patients to notify health care professional if pregnancy is planned or suspected or if breastfeeding.

Evaluation/Desired Outcomes

  • Decrease in dry mouth in patients with Sjögren's disease.
