It works by reducing the amount of acid your stomach produces. This medicine belongs to a class of drugs known as H2 blockers (or H2-antagonists) and acts by blocking the H2 receptors, that stops the cells from producing excessive stomach acid.
Acid is produced naturally in the stomach to help you digest food. However, excessive amounts of acid (due to various reasons) can irritate the lining of your stomach, ultimately leading to ulcers, inflammation, and other conditions.
This medicine is available as both a generic and brand-name drug and is available in an over-the-counter form and a prescription form. The prescription form (found as a table, tablet, oral syrup, or oral capsule) is used to treat gastroesophageal reflux disease, ulcers, erosive esophagitis, and other conditions. The over-the-counter form is used to treat acid indigestion, heartburn, and upset stomach.
In October 1984, the Food and Drug Administration approved this medicine. It is on the WHO’s List of Essential Medicines, that is a list with the safest and effective meds required in a health system.
Take this H2 blocker by mouth without or with food, typically once or twice a day or as directed by your healthcare provider. Also, this medicine may be prescribed 4 times per day for some disorders.
It is used to treat gastroesophageal reflux disease, a condition in which the muscle at the end of your esophagus does not close properly and leads to a backward flow of acid from the stomach which causes injury of the food pipe or heartburn.
Furthermore, it is used in conditions in which the stomach produces too much acid, like – Zollinger-Ellison syndrome (a disorder in which the human body produces too much of the hormone gastrin). Also, this medicine is used to prevent and treat ulcers in the intestines and stomach.
More importantly, it is used to prevent bleeding from stress ulceration in the gut in patients who are critically ill.

The over-the-counter form is used to treat heartburn (commonly due to regurgitation of gastric acid into the esophagus).
This drug is on the WHO’s List of Essential Medicines. It was discovered in 1979 and was approved by the FDA in 1989.

Ranitidine vs Omeprazole – Which Is Better To Reduce Stomach Acid?
Both medicines are available over-the-counter, and according to research, both are effective to relieve gastroesophageal reflux disease heartburn symptoms. However, both medicines work in different methods to reduce stomach acid – one is an H2 blocker and the other is a proton-pump inhibitor.
Ranitidine starts working within 24 hours after ingesting, and Omeprazole also starts working within 24 hours, but it may take up to 96 hours for the full effect.
