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).

Any drug which causes the onset of an allergic reaction.

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.

A cyclooxygenase inhibitor that interferes with the action of cyclooxygenase 2.

A cyclooxygenase inhibitor that interferes with the action of cyclooxygenase 1.

A drug that has principally analgesic, antipyretic and anti-inflammatory actions. Non-narcotic analgesics do not bind to opioid receptors.

Any drug which causes the onset of an allergic reaction.

A drug that increases uric acid excretion by the kidney (uricosuric drug), decreases uric acid production (antihyperuricemic), or alleviates the pain and inflammation of acute attacks of gout.

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.

A drug that has principally analgesic, antipyretic and anti-inflammatory actions. Non-narcotic analgesics do not bind to opioid receptors.
