Domstal O Capsule 15's belongs to a group of medicines called gastrointestinal agents used to treat heartburn, indigestion, epigastric pain, gastro-oesophageal reflux disease (GERD), peptic ulcers and Zollinger-Ellison syndrome. Gastroesophageal reflux disease (GERD) occurs when stomach acid frequently flows back into the food pipe (oesophagus). Peptic ulcers are sores that develop on the inner lining of the intestine and stomach. Zollinger-Ellison syndrome is characterised by the formation of tumours in the upper part of the small intestine, which leads to excess acid production.

Domstal O Capsule 15's is a combination of two drugs, namely: Omeprazole (proton pump inhibitor) and Domperidone (a dopamine antagonist). Omeprazole works by blocking the action of an enzyme called gastric proton pump, which is responsible for the production of acid Domperidone works by increasing the movements and contractions of stomach muscle. Together, Domstal O Capsule 15's helps in treating acidity.

Gastroesophageal reflux disease (GERD): It occurs when stomach acid frequently flows back into the food pipe (oesophagus). This backflow (acid reflux) irritates the food pipe and causes heartburn. Symptoms include heartburn, sour or bitter taste in the mouth, and difficulty swallowing.

Peptic ulcers: Peptic ulcers are sores that develop on the lining of the stomach and intestine due to erosion of the stomach's protective lining. Symptoms include nausea, changes in appetite, bloody or dark stools, unexplained weight loss, vomiting, and indigestion

Zollinger-Ellison syndrome: It is characterised by the formation of tumours in the upper part of the small intestine, which leads to excess acid production. Symptoms include bloating, burping, weight loss, loss of appetite, nausea, and vomiting.
