Please note, this OEL/ADE monograph also applies to Sodium antipyrine (CAS RN 12379-37-2) and Antipyrine salicylate (CAS RN 520-07-0). Antipyrine, also known as phenazone, is an analgesic, antipyretic, and anti-inflammatory drug. It is a nonsteroidal anti-inflammatory drug (NSAID). The mechanism of action of antipyrine is multifaceted (7). Antipyrine is thought to act primarily in the central nervous system (CNS), increasing the pain threshold by inhibiting both isoforms of cyclooxygenase, cyclooxygenase (COX)-1, COX-2, and COX-3 enzymes involved in prostaglandin (PG) synthesis. Prostaglandins are lipid compounds that play key roles in inflammation and pain signaling pathways. By inhibiting these enzymes, antipyrine effectively reduces the production of prostaglandins, thereby diminishing inflammation and pain. Additionally, antipyrine's antipyretic properties are believed to be mediated through its effects on the hypothalamus, the part of the brain responsible for regulating body temperature. By altering the hypothalamic set point for temperature control, the drug helps to reduce fever.
