Brief Summary:
Current treatment for gastroesophageal reflux disease (GERD) confirms an unmet need in patients, based on slow onset of action and an inability to provide 24-hour gastric-acid suppression. Clinical data on AH234844 demonstrates a rapid onset of action, high potency, and prolonged duration of effect. The present study endeavors, in part, to compare lavoltidine to two GERD drugs, NEXIUM and ranitidine.

Condition or disease Intervention/treatment Phase
Gastroesophageal Reflux Disease Reflux, Gastroesophageal Drug: AH23844 (lavoltidine) Drug: NEXIUM (esomeprazole) Drug: ZANTAC (ranitidine) Phase 2

Detailed Description:
A three-part study in healthy male volunteers to determine the most effective of four different lavoltidine doses on gastric pH and to compare the most effective dose with NEXIUM (esomeprazole) 40mg for the inhibition of gastric-acid secretion and with ranitidine (300mg/day) for the amount of pharmacodynamic tolerance
