Indomethacin¿¡ ´ëÇÑ Mechanism_Of_Action Á¤º¸ Antiinflammatory effects of Indomethacin are believed to be due to inhibition of cylooxygenase in platelets which leads to the blockage of prostaglandin synthesis. Antipyretic effects may be due to action on the hypothalamus, resulting in an increased peripheral blood flow, vasodilation, and subsequent heat dissipation.
Pharmacology
Indomethacin¿¡ ´ëÇÑ Pharmacology Á¤º¸ Indomethacin, a nonsteroidal antiinflammatory drug (NSAID) with analgesic and antipyretic properties, is used to treat osteoarthritis and control acute pain.
Indomethacin¿¡ ´ëÇÑ Toxicity Á¤º¸ The following symptoms may be observed following overdosage: nausea, vomiting, intense headache, dizziness, mental confusion, disorientation, or lethargy. There have been reports of paresthesias, numbness, and convulsions. The oral LD50 of indomethacin in mice and rats (based on 14 day mortality response) was 50 and 12 mg/kg, respectively.
