Roxatidine acetate is a specific and competitive histamine H2 receptor antagonist drug that is used to treat gastric ulcers, Zollinger–Ellison syndrome, erosive esophagitis, gastro-oesophageal reflux disease, and gastritis.[1][2]

Pharmacodynamic studies showed that 150 mg of roxatidine acetate were optimal in suppressing gastric acid secretion, and that a single bedtime dose of 150 mg was more effective than a dose of 75 mg twice daily in terms of inhibiting nocturnal acid secretion.[1]

It is available in countries including China, Japan, Korea, Germany, Italy, the Netherlands, Greece and South Africa.[2]
