Distinguishing the impact of dexlansoprazole on heartburn vs. regurgitation in
patients with gastro-oesophageal reflux disease. 
(EE)... CONCLUSIONS: Dexlansoprazole appears to be effective in improving both heartburn
A multicenter, randomized, comparative study to determine the appropriate dose of lansoprazole for use in the diagnostic test for gastroesophageal reflux disease. [2011.09]
BACKGROUND/AIMS: The diagnostic proton pump inhibitor test (PPI test) is a method used in diagnosing gastroesophageal reflux disease (GERD). This study aimed to determine the appropriate dose of lansoprazole for use in the diagnostic test for GERD... CONCLUSIONS: In this multicenter, randomized study of Korean patients, the standard dose of lansoprazole was as effective as a high dose of lansoprazole in relieving the symptoms of GERD, regardless of the presence of ERD, by day 14 of treatment.
Preventive effects of lansoprazole and famotidine on gastric mucosal injury induced by low-dose aspirin in Helicobacter pylori-negative healthy volunteers. [2011.07]
The preventive effects of lansoprazole and famotidine on low-dose aspirin-induced gastric mucosal injury in relation to gastric acidity were compared in healthy Japanese volunteers. Fifteen Helicobacter pylori-negative volunteers with different CYP2C19 genotypes were randomly administered aspirin 100 mg, aspirin plus famotidine 20 mg twice daily, or aspirin plus lansoprazole 15 mg once daily for 7 days each in a crossover fashion.
Lansoprazole for secondary prevention of gastric or duodenal ulcers associated with long-term low-dose aspirin therapy: results of a prospective, multicenter, double-blind, randomized, double-dummy, active-controlled trial. [2011.06]
BACKGROUND: The efficacy of low-dose lansoprazole has not been established for the prevention of recurrent gastric or duodenal ulcers in those receiving long-term low-dose aspirin (LDA) for cardiovascular and cerebrovascular protection. This study sought to examine the efficacy of low-dose lansoprazole (15 mg once daily) for the secondary prevention of LDA-associated gastric or duodenal ulcers... CONCLUSION: Lansoprazole was superior to gefarnate in reducing the risk of gastric or duodenal ulcer recurrence in patients with a definite history of gastric or duodenal ulcers who required long-term LDA therapy.
The effect of dexlansoprazole MR on nocturnal heartburn and GERD-related sleep disturbances in patients with symptomatic GERD. [2011.03]
OBJECTIVES: Nocturnal heartburn and related sleep disturbances are common among patients with gastroesophageal reflux disease (GERD). This study evaluated the efficacy of dexlansoprazole MR 30 mg in relieving nocturnal heartburn and GERD-related sleep disturbances, improving work productivity, and decreasing nocturnal symptom severity in patients with symptomatic GERD... CONCLUSIONS: In patients with symptomatic GERD, dexlansoprazole MR 30 mg is significantly more efficacious than placebo in providing relief from nocturnal heartburn, in reducing GERD-related sleep disturbances and the consequent impairments in work productivity, and in improving sleep quality/quality of life.

lansoprazole 30 mg to oral lansoprazole 30 mg capsules in subjects with erosive esophagitis.
Study Comparing Esomeprazole Magnesium 40mg Once Daily Versus Lansoprazole 30 mg Twice Daily in Symptom Control of Subjects With Persistent GERD [Completed]
A double-blind study comparing Esomeprazole Magnesium 40 mg once daily and Lansoprazole 30 mg
twice daily to control the symptoms in patients with gastroesophageal reflux disease (GERD)
with continued heartburn symptoms with a course of therapy of 30 mg twice daily
Efficacy/Safety of Lansoprazole in Patients With Frequent Nighttime Heartburn [Completed]
Heartburn, a burning sensation in the chest or throat, occurs in many individuals when acidic
stomach contents move upward into the esophagus from the stomach. This study will
investigate the safety and efficacy of lansoprazole 15 mg or 30 mg administered once a day in
preventing frequent nighttime heartburn.
