Omeprazole + sodium bicarbonate is a combination drug that is used in the treatment of peptic ulcer disease. It is composed of two drugs: omeprazole and sodium bicarbonate.
Omeprazole is a drug that is known as a proton-pump inhibitor. It inhibits the secretion of acid in the stomach by blocking the enzyme system of hydrogen and potassium adenosine triphosphate, otherwise known as the proton pump of the parietal cells of the stomach.
Sodium bicarbonate is a compound that can reduce stomach acid. It is used as an antacid for the treatment of heartburn, upset stomach and indigestion. It is quick-acting but is used only for temporary relief.
