Lansoprazole was patented in 1984 and came into medical use in 1992.[7] It is available as a generic medication.[5] In 2021, it was the 216th most commonly prescribed medication in the United States, with more than 1million prescriptions.[8][9]
Helicobacter pylori infection, alongside antibiotics (adjunctive treatment), treatment to kill H. pylori causing ulcers or other problems involves using two other drugs besides lansoprazole known as "triple therapy", and involves taking twice daily for 10 or 14 days lansoprazole, amoxicillin, and clarithromycin
It is a racemic 1:1 mixture of the enantiomersdexlansoprazole and levolansoprazole.[18] Dexlansoprazole is an enantiomerically pure active ingredient of a commercial drug as a result of the enantiomeric shift. Lansoprazole's plasma elimination half-life (1.5 h) is not proportional to the duration of the drug's effects to the person (i.e., gastric acid suppression).[19]
Lansoprazole was originally synthesized at Takeda and was given the development name AG 1749.[20] Takeda patented it in 1984 and the drug launched in 1991.[21] In the United States, it was approved for medical use in 1995.[22]
