R-lansoprazole compositions and methods

摘要

Methods and compositions are disclosed utilizing optically pure (+) lansoprazole for the treatment of S ulcers in humans while substantially reducing the concomitant liability of adverse effects associated with the racemic mixture of lansoprazole. The optically pure (+) isomer is also useful for the treatment of gastroesophageal reflux. (+) Lansoprazole is an inhibitor of H+ release and is therefore useful in the treatment of other conditions related to gastric hypersecretion such as Zollinger-Ellison Syndrome.
