Study Overview

• Status: Completed
• Conditions: GERD; EPS
• Intervention / Treatment: Drug: Omeprazole 20mg; Other: Neobianacid® placebo; Device: Neobianacid®; Other: Omeprazole placebo

Detailed Description

Comparison of heartburn or epigastric pain severity following administration of Neobianacid® (Group B) or omeprazole (Group A) from day 0 to day 27.
