This study aimed to investigate the effects of various concentrations of cevimelines (CVMs) and compare them with commercial drugs in a murine model of dry eye. The experimental mouse model used male and female NOD.B10.H2b mice over 12 weeks of age. Desiccation stress was performed at 30–40% ambient humidity, and subcutaneous injection of 0.5 mg/0.2 mL scopolamine hydrobromide was performed four times a day for 10 days. The efficacy of various concentrations of CVMs (seven experimental groups) was first evaluated, and then 2% CVM was compared with commercial drugs, such as cyclosporine A (CsA), diquafosol (DQS), and rebamipide (REB) (seven experimental groups). The clinical changes, including tear production, corneal irregularity, and fluorescein staining, were measured after the instillation of various concentrations of CVMs and commercial drugs for 0, 3, 5, 7, and 10 days. Histological changes, such as corneal detachment, conjunctival goblet cell and mucin density staining, were assessed by staining the cornea or conjunctiva with hematoxylin-eosin, periodic acid-Schiff, and alcian blue. The expression of inflammatory markers and mucin factors was detected by immunohistochemistry and immunofluorescence in the lacrimal gland, cornea, and conjunctiva. Tear production was significantly increased in the 2% CVM group and was similar to that in the DQS and REB groups (P
