Quizplus · Accepted Answer

H2 (histamine 2) receptors are found in the stomach and are responsible for stimulating gastric acid secretion. Drugs that block these receptors, known as H2 receptor antagonists, are used to reduce acid production and are therefore useful in treating conditions associated with excess gastric acid such as peptic ulcer disease (B) and gastroesophageal reflux disease (C). They are also used in conditions where reducing gastric acid is beneficial, such as in excess gastric acid production (A). Conditions like allergic rhinitis (D) and seasonal allergies (E) involve histamine 1 (H1) receptors, not H2, and are treated with H1 receptor antagonists, not H2 receptor antagonists.
