Camostat mesilate (FOY-305) is a synthetic f low-molecular weight protease inhibitor. It is able to inhibit trypsin, prostasin, matriptase and plasma kallikrein. In addition camostat attenuates airway epithelial sodium channel function and enhances mucociliary clearance. Camostat mesilate tablets (FOIPAN®) are approved in Japan and used for the treatment of remission of acute symptoms of chronic pancreatitis and postoperative reflux esophagitis.

Sample Use Guides

In Vivo Use Guide

1. Remission of acute symptoms of chronic pancreatitis. The usual dosage for oral use is 600 mg of camostat mesilate daily in three divided doses. The dosage may be adjusted according to the patient’s symptoms. 2. Postoperative reflux esophagitis. The usual dosage for oral use is 300 mg of camostat mesilate daily in three divided doses after each meal.

Route of Administration: Oral

In Vitro Use Guide

Camostat mesilate (500 uM) inhibited generation of TGF-beta by suppressing plasmin activity and reduced the activity of TGF-beta, which blocked in vitro activation of the rat hepatic stellate cells.
