Famotidine belongs to a class of medications known as histamine-2 blockers. These drugs work by reducing the amount of acid produced in the stomach, providing relief for conditions such as heartburn, acid indigestion, and gastroesophageal reflux disease (GERD).

By targeting the histamine receptors in the stomach, famotidine helps to alleviate symptoms associated with excess acid production, offering efficient and long-lasting relief for those experiencing digestive issues.

Famotidine Drug Class

Famotidine belongs to the class of drugs known as histamine-2 (H2) receptor antagonists. It works by blocking the action of histamine, a natural substance in the body that stimulates stomach acid production. By inhibiting the action of histamine on H2 receptors in the stomach, famotidine reduces the amount of acid produced, helping to relieve symptoms of conditions such as heartburn, acid reflux, and ulcers.

This drug class is commonly used to treat gastroesophageal reflux disease (GERD), peptic ulcers, and other conditions that involve excess stomach acid production. Famotidine is available both over-the-counter and by prescription and is often used in combination with other medications to provide relief from symptoms and promote healing of the stomach lining.

Pharmacological Properties of Famotidine

Famotidine is a histamine H2-receptor antagonist that inhibits the production of stomach acid. It works by blocking the action of histamine, a chemical that stimulates the release of acid in the stomach. Famotidine reduces gastric acid secretion both basal and stimulated, and also decreases the volume of gastric secretions and increases the pH of the stomach.

It is absorbed rapidly after oral administration, with peak plasma concentrations reached within 1-3 hours. Famotidine has a half-life of about 2.5 to 3.5 hours in healthy individuals, but it may be extended in patients with impaired renal function. The drug is mainly metabolized in the liver and excreted in the urine, with about 65-70% of the dose eliminated unchanged in the urine.

Famotidine is primarily used for the treatment of gastrointestinal disorders such as gastric ulcers, duodenal ulcers, gastroesophageal reflux disease (GERD), and conditions that cause excessive stomach acid production. It provides quick relief from heartburn and indigestion by reducing the acidity of the stomach.

The drug is generally well-tolerated, with common side effects including headache, dizziness, constipation, and diarrhea. Rare but more serious adverse effects may include allergic reactions, liver problems, and changes in blood counts. Famotidine may interact with certain medications like ketoconazole, itraconazole, and atazanavir, so it is important to consult a healthcare provider before starting treatment with famotidine.

Gastroesophageal reflux disease (GERD) Famotidine helps to reduce the production of stomach acid, which can help to relieve symptoms of GERD such as heartburn, acid regurgitation, and difficulty swallowing.
Peptic ulcer disease Famotidine can be used to treat and prevent ulcers in the stomach and small intestine caused by excessive acid production.
Zollinger-Ellison syndrome This rare condition causes excessive acid production in the stomach, leading to ulcers. Famotidine can help to control acid secretion in patients with this syndrome.
