Axid, which is the brand name for the drug nizatidine, is classified as an H2 receptor antagonist. This class of medications works by blocking histamine at the H2 receptors in the stomach lining, which leads to a decrease in the production of stomach acid. This makes H2 receptor antagonists useful for treating conditions such as gastroesophageal reflux disease (GERD), peptic ulcers, and other acid-related disorders.

Understanding the role of H2 receptor antagonists is crucial in medication management, specifically in how they help alleviate symptoms related to excessive stomach acid. In contrast, analgesics are medications that relieve pain, antidepressants are used to treat symptoms of depression, and atypical antipsychotics are primarily used to manage psychiatric conditions such as schizophrenia and bipolar disorder. Each of these categories serves different therapeutic purposes, highlighting the significance of accurate medication classification in healthcare.
