4 Pharmacology and Biochemistry
4.1 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.)


Vasodilator Agents

Drugs used to cause dilation of the blood vessels. (See all compounds classified as Vasodilator Agents.)
