Effects of menthol on esophageal motility in humans: Studies using high-resolution manometry.

Intraluminal infusion of menthol reduces UES basal pressure and inhibits peristaltic frequency of secondary peristalsis. The data suggest that the triggering of secondary peristalsis is probably modulated by TRPM8-sensitive mechanoreceptors; however, the activation of TRPM8 from menthol does not alter esophageal motility following deglutition or distension-induced secondary peristalsis.
