In this article, we will delve into the world of famotidine 20mg tablets, exploring their benefits, working mechanisms, and potential side effects.

What is Famotidine?
Famotidine is a histamine-2 (H2) blocker, a class of medications that reduce the amount of acid produced by the stomach. It works by blocking the action of histamine, a chemical that stimulates the stomach to produce acid. By reducing stomach acid production, famotidine helps to alleviate symptoms such as heartburn, regurgitation, and stomach pain.
How Does Famotidine Work?
Famotidine works by binding to H2 receptors in the stomach, preventing histamine from stimulating acid production. This leads to a decrease in the amount of acid produced by the stomach, which in turn helps to reduce symptoms of acid reflux and other gastrointestinal disorders.
