5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Anti-Asthmatic Agents

Drugs that are used to treat asthma. (See all compounds classified as Anti-Asthmatic Agents.)


Anti-Allergic Agents

Agents that are used to treat allergic reactions. Most of these drugs act by preventing the release of inflammatory mediators or inhibiting the actions of released mediators on their target cells. (From AMA Drug Evaluations Annual, 1994, p475) (See all compounds classified as Anti-Allergic Agents.)


Anti-Inflammatory Agents

Substances that reduce or suppress INFLAMMATION. (See all compounds classified as Anti-Inflammatory Agents.)


Mast Cell Stabilizers

Compounds that prevent the release of inflammatory mediators from MAST CELLS. (See all compounds classified as Mast Cell Stabilizers.)
