Roles Classification
Biological Role(s): cyclooxygenase 2 inhibitor
A cyclooxygenase inhibitor that interferes with the action of cyclooxygenase 2.
non-narcotic analgesic
A drug that has principally analgesic, antipyretic and anti-inflammatory actions. Non-narcotic analgesics do not bind to opioid receptors.
Application(s): non-steroidal anti-inflammatory drug
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.
antineoplastic agent
A substance that inhibits or prevents the proliferation of neoplasms.
non-narcotic analgesic
A drug that has principally analgesic, antipyretic and anti-inflammatory actions. Non-narcotic analgesics do not bind to opioid receptors.
