About this medicine
DESCRIPTION Cevimeline is cis-2'-methylspiro {1-azabicyclo [2.2.2] octane-3, 5'-[1,3] oxathiolane} hydrochloride, hydrate (2:1). Its empirical formula is C 10 H 17 NOS.HCl.1/2 H 2 O, and its structural formula is: Cevimeline has a molecular weight of 244.79. It is a white to off white powder with a melting point range of 201 to 203°C. It is freely soluble in alcohol and chloroform, very soluble in water, and virtually insoluble in ether. The pH of a 1% solution ranges from 4.6 to 5.6. Inactive ingredients include lactose monohydrate, hydroxypropyl cellulose, and magnesium stearate; a hard gelatin capsule which contains D&C Yellow #10, FD&C Red #40, FD&C Yellow #6, titanium dioxide and gelatin; and an imprinting ink which contains shellac, iron oxide black, isopropyl alcohol, butyl alcohol, propylene glycol and ammonium hydroxide structure
Who should not take it
CONTRAINDICATIONS Cevimeline is contraindicated in patients with uncontrolled asthma, known hypersensitivity to cevimeline, and when miosis is undesirable, e.g., in acute iritis and in narrow-angle (angle-closure) glaucoma.
Warnings
WARNINGS Cardiovascular Disease: Cevimeline can potentially alter cardiac conduction and/or heart rate. Patients with significant cardiovascular disease may potentially be unable to compensate for transient changes in hemodynamics or rhythm induced by Cevimeline Hydrochloride Capsules. Cevimeline Hydrochloride Capsules should be used with caution and under close medical supervision in patients with a history of cardiovascular disease evidenced by angina pectoris or myocardial infarction. Pulmonary Disease: Cevimeline can potentially increase airway resistance, bronchial smooth muscle tone, and bronchial secretions. Cevimeline should be administered with caution and with close medical supervision to patients with controlled asthma, chronic bronchitis, or chronic obstructive pulmonary disease. Ocular: Ophthalmic formulations of muscarinic agonists have been reported to cause visual blurring which may result in decreased visual acuity, especially at night and in patients with central lens changes, and to cause impairment of depth perception. Caution should be advised while driving at night or performing hazardous activities in reduced lighting.
Reported side effects
ADVERSE REACTIONS Cevimeline was administered to 1777 patients during clinical trials worldwide, including SjÖgren's patients and patients with other conditions. In placebo-controlled SjÖgren's studies in the U.S., 320 patients received cevimeline doses ranging from 15 mg tid to 60 mg tid, of whom 93% were women and 7% were men. Demographic distribution was 90% Caucasian, 5% Hispanic, 3% Black and 2% of other origin. In these studies, 14.6% of patients discontinued treatment with cevimeline due to adverse events. The following adverse events associated with muscarinic agonism were observed in the clinical trials of cevimeline in SjÖgren's syndrome patients: *n is the total number of patients exposed to the dose at any time during the study. Adverse Event Cevimeline 30 mg (tid) n *= 533 Placebo (tid) n = 164 Excessive Sweating 18.7% 2.4% Nausea 13.8% 7.9% Rhinitis 11.2% 5.4% Diarrhea 10.3% 10.3% Excessive Salivation 2.2% 0.6% Urinary Frequency 0.9% 1.8% Asthenia 0.5% 0.0% Flushing 0.3% 0.6% Polyuria 0.1% 0.6% In addition, the following adverse events (≥3% incidence) were reported in the SjÖgren's clinical trials: *n is the total number of patients exposed to the dose at any time during the study.

Interactions with other medicines
Drug Interactions Cevimeline should be administered with caution to patients taking beta adrenergic antagonists, because of the possibility of conduction disturbances. Drugs with parasympathomimetic effects administered concurrently with cevimeline can be expected to have additive effects. Cevimeline might interfere with desirable antimuscarinic effects of drugs used concomitantly. Drugs which inhibit CYP2D6 and CYP3A3/4 also inhibit the metabolism of cevimeline. Cevimeline should be used with caution in individuals known or suspected to be deficient in CYP2D6 activity, based on previous experience, as they may be at a higher risk of adverse events. In an in vitro study, cytochrome P450 isozymes 1A2, 2A6, 2C9, 2C19, 2D6, 2E1, and 3A4 were not inhibited by exposure to cevimeline.
If too much is taken
MANAGEMENT OF OVERDOSAGE Management of the signs and symptoms of acute overdosage should be handled in a manner consistent with that indicated for other muscarinic agonists: general supportive measures should be instituted. If medically indicated, atropine, an anti-cholinergic agent, may be of value as an antidote for emergency use in patients who have had an overdose of cevimeline. If medically indicated, epinephrine may also be of value in the presence of severe cardiovascular depression or bronchoconstriction. It is not known if cevimeline is dialyzable.
Before you take anything new
Tell your pharmacist or doctor about every medicine you take — including ones bought without a prescription, herbal products and supplements. Interactions are one of the most common avoidable causes of harm from medicines, and a pharmacist can check your full list in a couple of minutes.
