Overview
11 DESCRIPTION TRYPTYR (acoltremon ophthalmic solution) 0.003% contains an agonist of TRPM8 ion channels. Acoltremon’s chemical name is (1 R ,2 S ,5 R )-2-isopropyl- N -(4-methoxyphenyl)-5-methylcyclohexane-1-carboxamide. The molecular formula of acoltremon is C 18 H 27 NO 2 and has a molecular weight of 289.42 g/mol.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Studies in animals suggest that acoltremon, the active substance in TRYPTYR, is an agonist of transient receptor potential melastatin 8 (TRPM8) thermoreceptors. TRPM8 thermoreceptor stimulation has been shown to activate trigeminal nerve signaling leading to increased basal tear production. The exact mechanism of action for TRYPTYR in dry eye disease is unknown. 12.3 Pharmacokinetics PK was assessed in 25 patients with dry eye disease receiving TRYPTYR administration (1 drop twice daily) on Days 1, 14, and 90. A total of three (3) (12.0%) had plasma concentrations above 20 pg/mL (the lower limit of quantification), with the highest plasma concentration of 213 pg/mL.
