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): non-narcotic analgesic
A drug that has principally analgesic, antipyretic and anti-inflammatory actions. Non-narcotic analgesics do not bind to opioid receptors.
carcinogenic agent
A role played by a chemical compound which is known to induce a process of carcinogenesis by corrupting normal cellular pathways, leading to the acquistion of tumoral capabilities.
Application(s): 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.
non-narcotic analgesic
A drug that has principally analgesic, antipyretic and anti-inflammatory actions. Non-narcotic analgesics do not bind to opioid receptors.
