Rebamipide

Rebamipide, an amino acid derivative of 2(1H)-quinolinone, is used for mucosal protection, healing of gastroduodenal ulcers, and treatment of gastritis. It works by enhancing mucosal defense, scavenging free radicals, and temporarily activating genes encoding cyclooxygenase-2.

It has also been used for the treatment of Behçet's disease.
