Omeprazole domperidone pellets are a pharmaceutical formulation of two drugs, omeprazole and domperidone, used in the treatment of acid-related disorders such as gastroesophageal reflux disease (GERD) and peptic ulcer disease.

Omeprazole is a proton pump inhibitor (PPI) that works by blocking the proton pumps in the stomach lining, which are responsible for producing acid. By reducing the amount of acid in the stomach, omeprazole can alleviate symptoms such as heartburn, regurgitation, and stomach pain.

Domperidone is a dopamine antagonist that works by blocking the action of dopamine in the brain and the gut. It increases the contractions of the muscles in the stomach and intestines, which helps to move food through the digestive system more quickly. This can alleviate symptoms such as nausea, vomiting, and bloating.

The pellets are usually encapsulated in a capsule or a tablet to facilitate ingestion. The pellets are designed to release the drugs gradually, which allows for sustained blood levels and prolonged therapeutic effect.

Omeprazole domperidone pellets are available in different strengths and formulations, and their use should be prescribed by a healthcare provider based on the patient's medical condition, age, and other factors. As with all medications, omeprazole domperidone may cause side effects such as headache, nausea, diarrhea, and stomach pain, and patients should consult their healthcare provider if they experience any adverse effects.
