Acekol-SP tablets are a prescription medication used to treat certain types of acid-related stomach and intestinal problems. It is specifically used to reduce the symptoms of gastroesophageal reflux disease (GERD) and other conditions caused by excess stomach acid. Acekol-SP tablets contain the active ingredient omeprazole, which works by blocking the production of acid in the stomach. This helps to reduce the amount of acid reflux and reduce symptoms such as heartburn, regurgitation, and difficulty swallowing. It can also help to treat erosive esophagitis, an inflammation of the esophagus caused by stomach acid.
