5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Histamine Agonists

Drugs that bind to and activate histamine receptors. Although they have been suggested for a variety of clinical applications histamine agonists have so far been more widely used in research than therapeutically. (See all compounds classified as Histamine Agonists.)
