Any minor or unwanted substance introduced into the environment that can have undesired effects.

A molecular entity capable of donating a hydron to an acceptor (Bronsted base).

A molecular entity capable of accepting a hydron from a donor (Bronsted acid).

An agent capable of relieving pain without the loss of consciousness or without producing anaesthesia. In addition, analgesic is a role played by a compound which is exhibited by a capability to cause a reduction of pain symptoms.

A compound or agent that combines with cyclooxygenases (EC 1.14.99.1) and thereby prevents its substrate-enzyme combination with arachidonic acid and the formation of icosanoids, prostaglandins, and thromboxanes.

A xenobiotic (Greek, xenos "foreign"; bios "life") is a compound that is foreign to a living organism. Principal xenobiotics include: drugs, carcinogens and various compounds that have been introduced into the environment by artificial means.

An agent capable of relieving pain without the loss of consciousness or without producing anaesthesia. In addition, analgesic is a role played by a compound which is exhibited by a capability to cause a reduction of pain symptoms.

A drug used to treat rheumatoid arthritis.

An anti-inflammatory drug that is not a steroid. In addition to anti-inflammatory actions, non-steroidal anti-inflammatory drugs have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins.

A drug that prevents or reduces fever by lowering the body temperature from a raised state. An antipyretic will not affect the normal body temperature if one does not have fever. Antipyretics cause the hypothalamus to override an interleukin-induced increase in temperature. The body will then work to lower the temperature and the result is a reduction in fever.
