Prevacid Drug Class and Mechanism

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.[citation needed] 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 Uses

Prevents the production of acid in the stomach. How should I take Prevacid? Take lansoprazole capsules by mouth. Follow the directions on the prescription label. Swallow the capsules whole with a drink of water; do not crush or chew. Lansoprazole works best if taken on an empty stomach. It is best to take the capsules 30 to 60 minutes before food. Take your doses at regular intervals. Do not take your medicine more often than directed.

Prevacid Pregnancy

Teratology studies have been performed in pregnant rats at oral lansoprazole doses up to 150 mg/kg/day (40 times the recommended human dose based on BSA) and pregnant rabbits at oral lansoprazole doses up to 30 mg/kg/day (16 times the recommended human dose based on BSA) and have revealed no evidence of impaired fertility or harm to the fetus due to lansoprazole. There are, however, no adequate or well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
