Cevimeline (FKS-508; SNI-2011; AF-102B; SNK-508; trade name Evoxac) is a potent parasympathomimetic and muscarinic agonist thas has been approved for use in the treatment of dry mouth and Sjögren's syndrome, as well as Xerostomia symptoms.
| ln Vitro |
Cevimeline (0.1-100 μM) raises the intracellular Ca2+ content in parotid gland cells that have been digested [1].
|
|---|---|
| ln Vivo |
Male Wistar rats administered with cevimeline (0.008-0.016 mg/kg intraperitoneally) exhibited increased pressor response, increased salivation, and a gradual and sustained rise in parotid gland blood flow. In the subfornical organ, cevimeline, at 0.016 mg/kg, reduces angiotensin II-induced water intake and neuronal activity [1].
|
| Animal Protocol |
Animal/Disease Models: Male Wistar rats (8 weeks old) were injected with angiotensin-II[1].
Doses: 0.008 mg/kg, 0.016 mg/kg. Route of Administration: intraperitoneal (ip) injection. Experimental Results: Salivation increased slowly and persistently, and blood flow increased. Increased in parotid and pressor responses. |
| ADME/Pharmacokinetics |
Absorption, Distribution and Excretion
Absorption is rapid, with peak concentration reached in 1.5 to 2 hours. 84% of a 30 mg dose of cevimeline is excreted in the urine after 24 hours. 6 L/kg Excretion: Urine: 97%. Feces: 0.5%. It is unknown whether this drug is excreted into human breast milk. Following a single 30 mg capsule dose, cevimeline is rapidly absorbed, with a mean time to peak concentration of 1.5 to 2 hours. No accumulation of the active drug or its metabolites has been observed after multiple doses. The absorption rate decreases when taken with food, with a peak time of 1.53 hours on an empty stomach and 2.86 hours after a meal; peak concentration is reduced by 17.3%. Within the clinical dose range, the single oral dose is dose-dependent. The volume of distribution of cevimeline is approximately 6 L/kg, and its binding to human plasma proteins is less than 20%. This indicates that cevimeline binds extensively to tissues; however, the specific binding sites are unknown. After 24 hours, 84% of the 30 mg dose of cevimeline was excreted in the urine. After 7 days, 97% of the dose was recovered in the urine and 0.5% in the feces. Metabolism/Metabolites Cevimeline is primarily metabolized in the liver, with CYP2D6 and CYP3A4 isoenzymes responsible for its metabolism. Approximately 44.5% of the drug is converted to cis and trans sulfoxides, 22.3% to glucuronide conjugates, and 4% to cevimeline N-oxides. Approximately 8% of the trans sulfoxide metabolites are subsequently converted to their corresponding glucuronide conjugates. This study investigated the pharmacokinetics and metabolism of cevimeline in six healthy volunteers following a single oral dose of 14(C)-cevimeline. ...Twenty-four hours after administration, the average recoveries of the metabolites in urine were as follows: cevimeline 16.0%, cevimeline trans sulfoxide 35.8%, cevimeline cis sulfoxide 8.7%, and cevimeline N-oxide 4.1%. In addition, two unknown metabolites, UK-1 and UK-2, were detected, with recoveries of 14.6% and 7.7%, respectively. Liquid chromatography-mass spectrometry analysis and hydrolysis studies showed that UK-1 and UK-2 are cevimeline glucuronide conjugate and cevimeline trans sulfoxide, respectively. CYP2D6 and CYP3A3/4 isoenzymes are responsible for the metabolism of cevimeline. After 24 hours, 86.7% of the dose was recovered (16.0% of the original drug, 44.5% of cis and trans sulfoxides, 22.3% of glucuronide conjugate, and 4% of cevimeline N-oxide). Approximately 8% of the trans-sulfoxide metabolites are subsequently converted to their corresponding glucuronide conjugates and excreted. Cevimeline does not inhibit cytochrome P450 isoenzymes 1A2, 2A6, 2C9, 2C19, 2D6, 2E1, and 3A4. Biological Half-Life 5±1 hours Elimination: Approximately 5 hours. The mean half-life of cevimeline is 5±1 hours. |
| Toxicity/Toxicokinetics |
Hepatotoxicity
In premarket trials of cevimeline, the incidence of elevated serum enzymes was not significantly different from the placebo group, and no reports of acute liver injury were observed. Since its market launch and wider use, cevimeline has not been associated with any clinically visible cases of liver injury. Probability Score: E (Unlikely to cause clinically visible liver injury). Protein Binding 20% Interactions Due to the possibility of conduction disturbances, cevimeline should be used with caution in patients taking β-adrenergic antagonists. Concomitant use of drugs with parasympathomimetic effects with cevimeline may have an additive effect. Cevimeline may interfere with the anticholinergic effects of concomitantly taken drugs. Drugs that inhibit CYP2D6 and CYP3A3/4 may also inhibit the metabolism of cevimeline. Based on past experience, individuals with known or suspected CYP2D6 deficiency should use cevimeline with caution, as they may have a higher risk of adverse events. |

| Additional Infomation |
Cevimeline is a parasympathomimetic drug that acts as an agonist of muscarinic acetylcholine receptors M1 and M3. The U.S. Food and Drug Administration (FDA) has approved it for the treatment of dry mouth symptoms associated with Sjögren's syndrome. Cevimeline is an oral cholinergic agonist used to treat dry mouth symptoms in patients with dry keratoconjunctivitis (Sjögren's syndrome). No cases of elevated serum enzymes or clinically significant liver injury have been observed during treatment with cevimeline. Cevimeline is a cholinergic analogue that stimulates glandular secretion. It binds to and activates muscarinic receptors, thereby increasing the secretion of exocrine salivary and sweat glands. This cholinergic agonist also increases the tone of smooth muscle in the gastrointestinal and urinary tracts. Cevimeline is being investigated for the treatment of dry mouth induced by radiation therapy to the head and neck. Drug Indications: For the treatment of dry mouth symptoms in patients with Sjögren's syndrome.
FDA Label Mechanism of Action M then-and-sodium muscarinic receptor agonists bind to and activate muscarinic M1 and M3 receptors. M1 receptors are commonly found in secretory glands (such as salivary and sweat glands), and their activation leads to increased secretion. M3 receptors are present in smooth muscle and many glands, helping to stimulate salivary gland secretion; their activation typically leads to smooth muscle contraction and increased glandular secretion. Therefore, with increased saliva production, dry mouth symptoms are relieved. Cevimeline hydrochloride is a quinine ring derivative of acetylcholine and a cholinergic agonist that binds to muscarinic receptors. At adequate doses, muscarinic agonists can lead to increased secretion from exocrine glands (such as sweat and salivary glands) and increased smooth muscle tone in the gastrointestinal and urinary tracts. Cevimeline has a higher affinity for muscarinic receptors on the epithelial cells of lacrimal and salivary glands than for those on myocardial tissue. Cevimeline's structure is unrelated to other existing drugs, but its pharmacological action is similar to pilocarpine, another oral cholinergic agonist that primarily acts as a muscarinic. Both drugs stimulate damaged but still functional residual salivary gland tissue. Therapeutic Use Cevimeline is indicated for the treatment of dry mouth, a common symptom of Sjögren's syndrome. /US Product Label Contains/ Drug Warnings FDA Pregnancy Risk Class: C/Risk cannot be ruled out. Adequate, well-controlled human studies are lacking, and animal studies have not shown any risk to the fetus or lack relevant data. Use of this drug during pregnancy may cause harm to the fetus; however, the potential benefits may outweigh the potential risks. / The safety and efficacy of cevimeline in the treatment of Alzheimer's disease dementia have not been established. Use of cevimeline may cause excessive sweating and may lead to dehydration. If this occurs, patients should drink plenty of water and consult a doctor. There is a risk of changes in cardiac conduction and/or heart rate. Patients with clinically significant cardiovascular disease may not be able to compensate for transient hemodynamic or cardiac rhythm changes caused by cevimeline. Patients with a history of cardiovascular disease (e.g., angina, myocardial infarction) should use this medication with caution and under close medical supervision. For more complete data on cevimeline (14 in total), please visit the HSDB record page. Pharmacodynamics Cevimeline is a cholinergic agonist that binds to muscarinic receptors. Sufficient doses of muscarinic agonists can increase the secretion of exocrine glands such as salivary and sweat glands, and increase the tone of smooth muscle in the gastrointestinal and urinary tracts. |
