[Lansoprazole--profile of a new proton pump inhibitor]

Lansoprazole, a new proton pump inhibitor, selectively inhibits the H+/K(+)-ATPase. Its inhibitory effect on basal and gastrin stimulated gastric acid secretion is equal to omeprazole and stronger than that of H2-receptor antagonists. Healing rates concerning gastric and duodenal ulcers and refluxesophagitis are significantly higher compared to H2-receptor antagonists and at least comparable to omeprazole. Regarding pilot studies in H. pylori eradication therapy, lansoprazole in combination with various antibiotics is expected to show good eradication rates. Considering its excellent safety and interaction profile lansoprazole is effective and safe in treating acid related disorders.
