title: [Clinical effect of proton pump inhibitors on reflux esophagitis].
abstract: The clinical efficacy of proton pump inhibitors (PPI, omeprazole 20 mg or lansoprazole 30 mg), once daily, after breakfast, was studied in patients with erosive/ulcerative reflux esophagitis. The following results were obtained. 1) Twenty-four hour esophageal pH monitoring was performed before treatment and on 7th day of PPI medications. Omeprazole reduced the percent time pH less than 4 from 29.1 to 1.2 and lansoprazole from 68.0 to 2.4. 2) The cumulative disappearance rate of overall symptom was 52% after 1 week and 62% after 2 weeks with omeprazole these were 66% and 91%, and with lansoprazole respectively 3) The endoscopic healing rate was 63% was after 2 weeks and 76% after 4 weeks with omeprazole medication, and 76% and 97% respectively with lansoprazole. These results indicate that PPI medication inhibits the acid reflux almost completely and is a more useful therapeutic agent for GERD than H2-antagonists.
