Abstract

Antihistamines comprise a broad class of medicines that include the first-generation, centrally-acting, H1-receptor antagonists (e.g. chlorpheniramine, diphenhydramine) and the newer, second-generation, non-sedating, H1-receptor antagonists (e.g. loratadine, cetirizine). Other antihistamines, such as cimetidine or ranitidine, work on the H2-receptors causing inhibition of gastric acid secretion. This summary of antihistamines limits discussion to the H1-receptor antagonists.
