Lansoprazole is a proton pump inhibitor (PPI) in the same pharmacologic class as omeprazole. Lansoprazole has been marketed for many years and is one of several PPI's available.
Lansoprazole's plasma elimination half-life is not proportional to the duration of the drug's effects (i.e. gastric acid suppression). The mean plasma elimination half-life is 1.5 hours, and the effects of the drug last for over 24 hours after it has been used for 1 day or more.
Prevacid is now manufactured and distributed by Novartis Consumer Health.
Lansoprazole is indicated for:
Treatment of ulcers of the stomach and duodenum, and NSAID-induced ulcers
Treatment of gastroesophageal reflux disease (GERD) (also known as acid reflux disease)
