Irritants

Medical Definition:	Drugs that act locally on cutaneous or mucosal surfaces to produce inflammation; those that cause redness due to hyperemia are rubefacients; those that raise blisters are vesicants and those that penetrate sebaceous glands and cause abscesses are pustulants; tear gases and mustard gases are also irritants.
Guide Notes:	note X ref COUNTERIRRITANTS but use no qualif with it (i.e., adv eff of a counterirritant is COUNTERIRRITANTS, not COUNTERIRRITANTS /adv eff since this would print as a misleading IRRITANTS /adv eff)
Also Called:	Pustulants,Rubefacients,Counterirritants,Vesicants
