New Topical tReatment Options for Symptomatic patiEnts With Nonerosive gastroesophageaL Reflux dIsease (The RELIEF Trial)

The goal of this randomized, double-blind, single-center clinical trial RELEIF is to learn if medical devices work to decrease symptoms of gastroesophageal reflux disease (GERD) in adults' patients. It will also teach us about safety, tolerability and improvement of patient's quality of life during and after taking medical device. The main questions it aims to answer are: * Does medical device relieve reflux symptoms? * Does medical device improve the quality of life of patients with GERD symptoms? Researchers will compare medical device to a placebo (a look-alike substance that contains no drug) to see if medical device works in GERD gastroesophageal reflux disease . Participants will: * Take medical device or a placebo every day (4 times a day) for 14 days * Stop taking medical device or placebo for 7 days (wash out period) * Switch the therapy for medical device or placebo for next 14 days * Visit the clinic 4 times during 35 days of this study for checkups and tests * Keep a diary of their symptoms and the number of times they use a medical device * Fill out the form to collect all necessary data.
