4 Pharmacology and Biochemistry

4.1 MeSH Pharmacological Classification

Histamine Antagonists

Drugs that bind to but do not activate histamine receptors, thereby blocking the actions of histamine or histamine agonists. Classical antihistaminics block the histamine H1 receptors only. (See all compounds classified as Histamine Antagonists.)

4.2 ATC Code

R - Respiratory system

R06 - Antihistamines for systemic use

R06A - Antihistamines for systemic use

R06AX - Other antihistamines for systemic use

R06AX31 - Quifenadine
