Ezium Cap is an effective drug that contains esomeprazole, a proton pump inhibitor used to treat gastroesophageal reflux disease (GERD) and other related diseases. The medication relieves symptoms such as heartburn, acid reflux, and stomach discomfort by decreasing the amount of acid produced in the stomach. The active ingredient acts by blocking the proton pumps in the stomach that produce acid, lowering the amount of acid in the stomach and preventing it from travelling back up into the esophagus. It is especially beneficial for patients who suffer from persistent heartburn or GERD because it can provide long-term relief and help prevent return of symptoms.
