Roles Classification
Biological Role(s): H1-receptor antagonist
H1-receptor antagonists are the drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine.
Application(s): antipruritic drug
A drug, usually applied topically, that relieves pruritus (itching).
H1-receptor antagonist
H1-receptor antagonists are the drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine.
local anaesthetic
Any member of a group of drugs that reversibly inhibit the propagation of signals along nerves. Wide variations in potency, stability, toxicity, water-solubility and duration of action determine the route used for administration, e.g. topical, intravenous, epidural or spinal block.
A drug used to prevent nausea or vomiting. An antiemetic may act by a wide range of mechanisms: it might affect the medullary control centres (the vomiting centre and the chemoreceptive trigger zone) or affect the peripheral receptors.
A central nervous system depressant used to induce drowsiness or sleep or to reduce psychological excitement or anxiety.
anti-allergic agent
A drug used to treat allergic reactions.

General Comment
2011-02-04 A sedating antihistamine with antimuscarinic properties, promethazine is used as the monohydrochloride salt for the symptomatic relief of a variety of allergic conditions including conjunctivitis, rhinitis, and urticaria, as well as pruritic skin disorders. The anti-emetic action of both the hydrochloride and the teoclate (8-chlorotheophylline) salts is used for the prevention of nausea in cases of motion sickness and post-operative vomiting.
