The half-life of the ketorolac tromethamine S-enantiomer was approximately 2.5 hours (SD Â± 0.4) compared with 5 hours (SD Â± 1.7) for the R-enantiomer. In other studies, the half-life for the racemate has been reported to lie within the range of 5 to 6 hours.
Proton pump inhibitors (PPIs) are a group of drugs whose main action is a pronounced and long-lasting reduction of gastric acid production. Within the class of medications, there is no clear evidence that one agent works better than another. They are the most potent inhibitors of acid secretion available.
DRUG CLASS AND MECHANISM: Pantoprazole is in a class of drugs called proton pump inhibitors (PPIs), which block the production of acid by the stomach.Other drugs in the same class include lansoprazole (Prevacid), omeprazole (Prilosec) and rabeprazole (Aciphex).Proton pump inhibitors are used for the treatment of conditions such as ulcers, gastroesophageal reflux disease (GERD) and Zollinger-Ellison syndrome that are caused by stomach acid.RUG CLASS AND MECHANISM: Pantoprazole is in a class of drugs called proton pump inhibitors (PPIs), which block the production of acid by the stomach.
