4.2 Drug Indication

Flurbiprofen tablets are indicated for the acute or long-term symptomatic treatment of rheumatoid arthritis, osteorarthritis and anklosing spondylitis. It may also be used to treat pain associated with dysmenorrhea and mild to moderate pain accompanied by inflammation (e.g. bursitis, tendonitis, soft tissue trauma). Topical ophthalmic formulations may be used pre-operatively to prevent intraoperative miosis.


FDA Label


5 Pharmacology and Biochemistry
5.1 Pharmacology

Flurbiprofen, a nonsteroidal anti-inflammatory agent (NSAIA) of the propionic acid class, is structually and pharmacologically related to fenoprofen, ibuprofen, and ketoprofen, and has similar pharmacological actions to other prototypica NSAIAs. Flurbiprofen exhibits antiinflammatory, analgesic, and antipyretic activities. The commercially available flurbiprofen is a racemic mixture of (+)S- and (-) R-enantiomers. The S-enantiomer appears to possess most of the anti-inflammatory, while both enantiomers may possess analgesic activity.


5.2 MeSH Pharmacological Classification

Anti-Inflammatory Agents, Non-Steroidal

Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they 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. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects. (See all compounds classified as Anti-Inflammatory Agents, Non-Steroidal.)


Cyclooxygenase Inhibitors

Compounds or agents that combine with cyclooxygenase (PROSTAGLANDIN-ENDOPEROXIDE SYNTHASES) and thereby prevent its substrate-enzyme combination with arachidonic acid and the formation of eicosanoids, prostaglandins, and thromboxanes. (See all compounds classified as Cyclooxygenase Inhibitors.)


Analgesics

Compounds capable of relieving pain without the loss of CONSCIOUSNESS. (See all compounds classified as Analgesics.)

5.5 Absorption, Distribution and Excretion

Absorption

Fluribiprofen is rapidly and almost completely absorbed following oral administration. Peak plasma concentrations are reached 0.5 - 4 hours after oral administration.


Route of Elimination

Flurbiprofen is poorly excreted into human milk. Following dosing with flurbiprofen, less than 3% of flurbiprofen is excreted unchanged in the urine, with about 70% of the dose eliminated in the urine as parent drug and metabolites. Renal elimination is a significant pathway of elimination of flurbiprofen metabolites.


Volume of Distribution

14 L [Normal Healthy Adults]

12 L [Geriatric Arthritis Patients]

10 L [End Stage Renal Disease Patients]

14 L [Alcoholic Cirrhosis Patients]

0.12 L/kg


5.6 Metabolism/Metabolites

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.


5.7 Biological Half-Life

R-flurbiprofen, 4.7 hours; S-flurbiprofen, 5.7 hours


5.8 Mechanism of Action

Similar to other NSAIAs, the anti-inflammatory effect of flurbiprofen occurs via reversible inhibition of cyclooxygenase (COX), the enzyme responsible for the conversion of arachidonic acid to prostaglandin G2 (PGG2) and PGG2 to prostaglandin H2 (PGH2) in the prostaglandin synthesis pathway. This effectively decreases the concentration of prostaglandins involved in inflammation, pain, swelling and fever. Flurbiprofen is a non-selective COX inhibitor and inhibits the activity of both COX-1 and -2. It is also one of the most potent NSAIAs in terms of prostaglandin inhibitory activity.
