What class of medications does Axid belong to?

Antipsychotic
H2 receptor antagonist
Analgesic
Nonsteroidal anti-inflammatory

The correct answer is: H2 receptor antagonist

Axid, which is a brand name for the medication famotidine, falls under the class of H2 receptor antagonists. This class of medications works by blocking histamine H2 receptors in the stomach lining, which leads to a decrease in the production of stomach acid. H2 receptor antagonists are often used to treat conditions such as gastroesophageal reflux disease (GERD), peptic ulcers, and other conditions related to excessive stomach acid. Understanding the role of H2 receptor antagonists is essential for administering medications safely and effectively. These drugs are particularly beneficial for conditions involving the upper gastrointestinal tract where excessive acidity can cause discomfort or harm. Recognizing Axid as an H2 receptor antagonist supports a clearer understanding of its use in managing related gastrointestinal conditions, distinguishing it from other classes of medications that serve different purposes.
