4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Antipruritics

Agents, usually topical, that relieve itching (pruritus). (See all compounds classified as Antipruritics.)


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.)


Histamine H1 Antagonists

Drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine. Included here are the classical antihistaminics that antagonize or prevent the action of histamine mainly in immediate hypersensitivity. They act in the bronchi, capillaries, and some other smooth muscles, and are used to prevent or allay motion sickness, seasonal rhinitis, and allergic dermatitis and to induce somnolence. The effects of blocking central nervous system H1 receptors are not as well understood. (See all compounds classified as Histamine H1 Antagonists.)
