Pharmacology

Indication:	For relief of the signs and symptoms of rheumatoid arthritis and osteoarthritis. Also for the relief of mild to moderate pain.

Fenoprofen inhibits prostaglandin synthesis by decreasing the enzyme needed for biosynthesis. In patients with rheumatoid arthritis, the anti-inflammatory action of fenoprofen has been evidenced by relief of pain, increase in grip strength, and reductions in joint swelling, duration of morning stiffness, and disease activity (as assessed by both the investigator and the patient). In patients with osteoarthritis, the anti-inflammatory and analgesic effects of fenoprofen have been demonstrated by reduction in tenderness as a response to pressure and reductions in night pain, stiffness, swelling, and overall disease activity (as assessed by both the patient and the investigator). These effects have also been demonstrated by relief of pain with motion and at rest and increased range of motion in involved joints. In patients with rheumatoid arthritis and osteoarthritis, clinical studies have shown fenoprofen to be comparable to aspirin in controlling the aforementioned measures of disease activity, but mild gastrointestinal reactions (nausea, dyspepsia) and tinnitus occurred less frequently in patients treated with fenoprofen than in aspirin-treated patients. It is not known whether fenoprofen causes less peptic ulceration than does aspirin. In patients with pain, the analgesic action of fenoprofen has produced a reduction in pain intensity, an increase in pain relief, improvement in total analgesia scores, and a sustained analgesic effect. show less «
Mechanism of Action:	Fenoprofen's exact mode of action is unknown, but it is thought that prostaglandin synthetase inhibition is involved. Fenoprofen has been shown to inhibit prostaglandin synthetase isolated from bovine seminal vesicles.
Absorption:	Rapidly absorbed under fasting conditions, and peak plasma levels of 50 µg/mL are achieved within 2 hours after oral administration of 600 mg doses.
Protein binding:	99% to albumin.
Biotransformation:	About 90% of a single oral dose is eliminated within 24 hours as fenoprofen glucuronide and 4'-hydroxyfenoprofen glucuronide, the major urinary metabolites of fenoprofen.
Half Life:	Plasma half-life is approximately 3 hours.
Toxicity:	Symptoms of overdose appear within several hours and generally involve the gastrointestinal and central nervous systems. They include dyspepsia, nausea, vomiting, abdominal pain, dizziness, headache, ataxia, tinnitus, tremor, drowsiness, and confusion. Hyperpyrexia, tachycardia, hypotension, and acute renal failure may occur rarely following overdose. Respiratory depression and metabolic acidosis have also been reported following overdose with certain NSAIDs.
Affected organisms:	Humans and other mammals

Interactions

Food interaction:

Avoid alcohol.

Take with food to reduce irritation.

Drug interaction:

Trandolapril	The NSAID, Fenoprofen, may reduce the antihypertensive effect of Trandolapril. Consider alternate therapy or monitor for changes in Trandolapril efficacy if Fenoprofen is initiated, discontinued or dose changed.
Acenocoumarol	The NSAID, fenoprofen, may increase the anticoagulant effect of acenocoumarol.
Anisindione	The NSAID, fenoprofen, may increase the anticoagulant effect of anisindione.
Timolol	The NSAID, Fenoprofen, may antagonize the antihypertensive effect of Timolol.
Dicumarol	The NSAID, fenoprofen, may increase the anticoagulant effect of dicumarol.
