H2 Receptor Antagonists

H2-receptor antagonists are a type of medication used to reduce stomach acid production. They work by blocking histamine H2 receptors on cells in the stomach lining, which normally trigger acid secretion. This helps relieve conditions like heartburn, gastroesophageal reflux disease (GERD), and stomach ulcers by decreasing acidity and allowing healing. Common examples include ranitidine and famotidine. These medications are generally considered safe and effective for short-term use but should be taken under the guidance of a healthcare professional to manage dosages and potential side effects.
