HISTAMINE ANTAGONISTS Meaning and
Definition
-
Histamine antagonists, also known as H2 receptor antagonists or H2 blockers, are a class of medications that work by inhibiting the action of histamine on the H2 receptors in the body. Histamine is a naturally occurring chemical released by the body during an allergic reaction, which is responsible for causing symptoms such as itching, swelling, and inflammation.
Histamine antagonists are commonly used to treat conditions related to the overproduction of stomach acid, such as gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome. By blocking the H2 receptors in the stomach lining, these medications reduce the production of acid, providing relief from symptoms like heartburn, acid indigestion, and stomach pain.
Additionally, histamine antagonists have been used to prevent and treat symptoms related to allergies, such as hay fever and allergic rhinitis. By blocking the action of histamine on the H2 receptors in the nasal passages, these medications can help relieve symptoms like sneezing, runny nose, and nasal congestion.
Common examples of histamine antagonists include cimetidine, ranitidine, famotidine, and nizatidine. They are available in the form of tablets, capsules, and liquids, and are typically taken orally. These medications may have potential side effects, such as dizziness, headache, diarrhea, and constipation, although they are generally well tolerated.
Overall, histamine antagonists play a crucial role in managing conditions related to excessive histamine activity and have proven to be effective in providing relief from symptoms associated with excess stomach acid and allergies.

Etymology of HISTAMINE ANTAGONISTS
The word "histamine" comes from the Greek terms "histos", meaning "tissue", and "amine", referring to a compound containing a nitrogen atom. "Histamine" was coined by Henry Dale in 1910 to describe a substance found in tissues that had a role in dilating blood vessels and causing respiratory constriction.
The term "antagonist" comes from the Latin term "antagonista", which means "opponent" or "adversary". It was first used in English in the early 17th century to refer to an opponent in a contest or battle. In a medical context, an antagonist is a substance that binds to a receptor and prevents its activation by an agonist, thereby counteracting its effects.
"Histamine antagonists" is a compound term combining both elements.
