Clinical Trial Summary

Background: Rebound acid hypersecretion after proton pump inhibitors (PPIs) discontinuation may be accompanied by dyspepsia. Aim: To assess whether Spirulina platensis, by its anti-inflammatory properties, could minimize rebound symptoms after PPIs withdrawal.

Description:

Forty-five regular users of PPIs entered in a 28-day run-in phase of pantoprazole 40 mg/day, followed by clinical and endoscopic evaluation. In the absence of large hiatal hernia, peptic ulcer, or moderate to severe reflux esophagitis, patients stopped PPIs and were randomly assigned to receive Spirulina (1.6 g/day) or placebo for 2 months, when evaluation was repeated. Primary outcomes were dyspepsia and typical reflux symptoms (either appearance or maintenance of symptoms > 50% from baseline). Intention-to-treat analysis was applied.
