Background on Cevimeline

Cevimeline is a muscarinic receptor agonist especially on the M1 and M3 receptors. [1]

Cevimeline has been approved for use against symptoms of dry mouth by activating the M3 receptors of the parasympathetic nervous system. Cevimeline is effective and safe in improving symptoms of dry eye with 20 mg three times per day [2]. Cevimeline increased the intracellular Ca+ level in parotid gland acinar cells over 1 μM and rat, enhanced the excitability via muscarinic receptors, thereby, cevimeline alleviates dry mouth symptoms by stimulating secretion by the salivary glands. Cevimeline has a longer duration of salivation[3]. Cevimeline plays a part in Alzheimer’s disease. Cevimeline decreased Aβ (1–40) level in the cerebrospinal fluid (CSF) at 1 mg/kg without changing α-APPs in rabbit and significantly decreased CSF Aβ in AD patients.[4]

Comparison of the discontinuation rates and side-effect profiles of pilocarpine and cevimeline for xerostomia in primary Sjogren's syndrome.[Pubmed:25065774]

Clin Exp Rheumatol. 2014 Jul-Aug;32(4):575-7. Epub 2014 Jul 23.

OBJECTIVES: There are currently no head-to-head comparisons of sialagogues for Primary Sjogren's syndrome (pSS). We compared the tolerability and side effect profile of pilocarpine and Cevimeline in patients with pSS and determined clinical, laboratory and pathological variables associated with therapeutic failure. METHODS: We retrospectively reviewed the use of pilocarpine and Cevimeline in 118 patients with pSS who fulfilled the 2002 American European Consensus Group criteria in a University-based setting. Clinical, laboratory and pathological baseline variables were collected. Failure of therapy was defined as the clinician or patient's decision to stop treatment either due to lack of efficacy or side effects. RESULTS: Cevimeline was associated with lower failure rates compared to pilocarpine among first-time users: 27% vs. 47% (p=0.02), and all users: 32% vs. 61% (p<0.001). Severe sweating was the most frequent side effect leading to cessation of therapy and occurred more frequently in pilocarpine (25%) than Cevimeline (11%) users (p=0.02). Patients who previously failed one secretagogue were less likely to discontinue treatment with the other agent, 52% of first-time users vs. 27% of second-time users (p=0.004). Only ANA positivity was associated with failure: [59% vs. 38%] (p=0.03). CONCLUSIONS: pSS patients were more likely to continue Cevimeline than pilocarpine long-term due to fewer reported side effects with Cevimeline. Therapeutic failure of one secretagogue did not predict similar results with the other since second time users were more likely to continue long-term treatment.

Efficacy of cevimeline vs. pilocarpine in the secretion of saliva: a pilot study.[Pubmed:23600983]

Spec Care Dentist. 2013 May-Jun;33(3):123-7.

OBJECTIVES: To determine the efficacy and compare the side-effects of Cevimeline and pilocarpine in the secretion of saliva in patients with xerostomia. METHODS: A randomized, cross-over, double blind study was designed. Fifteen patients with diagnosis of xerostomia were assigned to take either 5 mg of pilocarpine or 30 mg of Cevimeline three times a day for four weeks. Salivary flow rates were measured during the initial baseline, first and second month appointments. Statistical analysis was carried out with ANOVA and post hoc t-tests. RESULTS: Twelve patients completed both medication treatments. Although both medications proved to increase salivary secretion, there was no significant difference between pilocarpine and Cevimeline. Also, the perceived side-effects between the two medications were similar. CONCLUSION: Both medications increased the secretion of saliva at the end of four weeks. However, there was a slightly higher increment in saliva with pilocarpine. However, the difference was not statistically significant.

An immunohistochemistry-based study on aquaporin (AQP)-1, 3, 4, 5 and 8 in the parotid glands, submandibular glands and sublingual glands of Sjogren's syndrome mouse models chronically administered cevimeline.[Pubmed:23925155]

Kurume Med J. 2013;60(1):7-19. Epub 2013 Aug 7.

Cevimeline is a muscarinic agonist that promotes saliva secretion and is used to treat Sjogren's syndrome (SS), an autoimmune disorder in which the exocrine glands that produce saliva are destroyed. Cevimeline is thought to affect the composition of saliva in part by regulating the localization of aquaporins (AQPs). In this study, we investigated the effects of chronic Cevimeline administration in the salivary glands of SS mice on the immunohistochemical localization of aquaporin (AQP)-1, 3, 4, 5 and 8. We used Cevimeline-untreated SS mice, treated SS mice, discontinued SS mice and untreated normal mice. AQP-5 was found in the apical and lateral membranes of acinar cells in the parotid and submandibular glands of Cevimeline-treated SS mice and untreated normal mice. Saliva secretion and AQP-5 localization were sustained in SS mice who were chronically administered Cevimeline and at four weeks after discontinuation. Unlike AQP-5, the localization of AQP-1, 3, 4 and 8 were not affected by Cevimeline administration. Our findings demonstrated that administration of Cevimeline maintains the proper localization of AQP-5 in the acinar cells of the salivary gland, which may promote salivation in chronically treated SS mice. Clinically, this suggests that chronic Cevimeline administration may be useful therapeutically for SS patients suffering from a decrease in saliva secretion by improving the disordered AQP-5 localization.

Structural characterization of cevimeline and its trans-impurity by single crystal XRD.[Pubmed:26609680]

J Pharm Biomed Anal. 2016 Jan 25;118:404-409.

Cevimeline is muscarinic receptor agonist which increases secretion of exocrine glands. Cevimeline base is a liquid (m.p. 20-25 degrees C) at ambient conditions, therefore its pharmaceutical formulation as a solid hydrochloride hemihydrate has been developed. The synthesis of Cevimeline yields its cis- and trans-isomers and only the cis-isomer is recognized as the API and used in the finished formulation. In this study structural and physicochemical investigations of hydrochloride hemihydrates of cis- and trans-Cevimelines have been performed. Single crystal X-ray analyses of both cis- and trans-isomers of Cevimeline are reported here for the first time. It was found that the cis-isomer, the API, has less dense crystal packing, lower melting point and higher solubility in comparison to the trans-isomer.

Description

Cevimeline (AF-102B) is a quinuclidine derivative of acetylcholine and a selective and orally active muscarinic M1 and M3 receptor agonist. Cevimeline stimulates secretion by the salivary glands and can be used as a sialogogue for xerostomia. Cevimeline can cross the blood-brain barrier (BBB).
