Rabesec-D tablet is a combination medicine used to treat gastroesophageal reflux disease (GERD) by relieving symptoms such as heartburn, stomach pain, indigestion, and nausea. GERD occurs when stomach acid flows back into the food pipe, irritating the sphincter and causing discomfort. The capsule is also effective in managing conditions like peptic ulcers and Zollinger-Ellison syndrome, where the stomach produces excessive acid. Rabesec-D tablet works by neutralizing stomach acid and promoting the easy passage of gas, providing relief from discomfort.
