Roles Classification
Chemical Role(s): Bronsted base
A molecular entity capable of accepting a hydron from a donor (Bronsted acid).
(via organic amino compound )
Biological Role(s): anticoronaviral agent
Any antiviral agent which inhibits the activity of coronaviruses.
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): sedative
A central nervous system depressant used to induce drowsiness or sleep or to reduce psychological excitement or anxiety.
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.
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.
antipruritic drug
A drug, usually applied topically, that relieves pruritus (itching).
anti-allergic agent
A drug used to treat allergic reactions.
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.
