Efficacy and Safety Evaluation of Neobianacid® in GERD and EPS
Efficacy and Safety Evaluation of Neobianacid® in GERD and EPS
Comparison of Neobianacid® clinical efficacy to omeprazole in relief of heartburn or
 epigastric pain
Comparison of heartburn or epigastric pain severity following administration of Neobianacid®
 (Group B) or omeprazole (Group A) from day 0 to day 27. An ad-hoc placebo will be also
 administered in both treatment arms. Then, a following phase (day 28-55) will follows in
 which Neobianacid® will be administered (on demand) to both treatment arms.

 Syndrome (EPS) or whose symptoms are consistent with a clinical diagnosis of
 uncomplicated EPS according to Rome III criteria.

 3. A gastroscopy is to be performed if not already performed during the previous 3 years

 as CYP2C19 or CYP3A4 inhibitors, as clarithromycin and voriconazole, or inductors, as
 rifampicin and St. John's wort, Hypericum, or both) or with any drug with which
 omeprazole, neobianacid or magaldrate are able to interact.
