Flurbiprofen¿¡ ´ëÇÑ Mechanism_Of_Action Á¤º¸ The antiinflammatory effect of flurbiprofen may result from the reversible inhibition of cyclooxygenase, causing the peripheral inhibition of prostaglandin synthesis. Flurbiprofen also inhibits the migration of leukocytes into sites of inflammation and prevents the formation of thromboxane A2, an aggregating agent, by the platelets.
Pharmacology
Flurbiprofen¿¡ ´ëÇÑ Pharmacology Á¤º¸ Flurbiprofen, a nonsteroidal antiinflammatory drug (NSAID) of the propionic acid class, is used for the relief of pain and inflammation associated with rheumatoid arthritis and osteoarthritis and for the inhibition of intraoperative miosis. Flurbiprofen exhibits antiinflammatory, analgesic, and antipyretic activities.
Flurbiprofen¿¡ ´ëÇÑ Absorption Á¤º¸ The mean oral bioavailability of flurbiprofen from tablets is 96% relative to an oral solution.

Biotransformation
Flurbiprofen¿¡ ´ëÇÑ Biotransformation Á¤º¸ Hepatic. Cytochrome P450 2C9 plays an important role in the metabolism of flurbiprofen to its major metabolite, 4¡¯-hydroxy-flurbiprofen. The 4¡¯-hydroxy-flurbiprofen metabolite showed little anti-inflammatory activity in animal models of inflammation.
Toxicity
Flurbiprofen¿¡ ´ëÇÑ Toxicity Á¤º¸ LD50=10 mg/kg (orally in dogs).
