Esaprazole, also known as hexaprazole, was developed in the 1980s as a drug for the treatment of gastric and duodenal ulcers. Esaprazole exerts a dose-dependent cytoprotective effect on the gastric mucosa in man. It was shown to have a dose-dependent antisecretory activity, which was particularly evident on secretion volume and acid output. Esaprazole completed phase II clinical trials with only a few minor side effects being reported, but was shown to be less effective than Cimetidine and Ranitidine at healing ulcers. Esaprazole is a weak sigma opioid receptor and muscarinic acetylcholine receptors M3 and M5 ligand. Esaprazole analogs with many compounds showing neuroprotective properties.
