FENOPROFEN

Описание

Fenoprofen is used as its calcium salt dihydrate in the treatment of rheumatoid arthritis and osteoarthritis at a daily dose of 1.2 – 3.0 g. The drug is rapidly absorbed and excreted with a plasma half-life of about 3 h despite being extensively bound (99 %) to plasma protein. Fenoprofen is well tolerated, with dyspepsia being the chief adverse effect.

Использование

Fenoprofen is used in treating symptoms of rheumatoid arthritis and osteoarthritis; however, fenoprofen exhibits a number of undesirable side effects.

Показания

Fenoprofen (Nalfon) is chemically and pharmacologically similar to ibuprofen and is used in the treatment of rheumatoid arthritis, osteoarthritis, and mild to moderate pain. GI effects such as dyspepsia and pain are most common, although dizziness, pruritus, and palpitations may occur. GI bleeding, sometimes severe, has been reported, and interstitial nephritis has been rarely associated with this drug. Concomitant administration of aspirin decreases the biological half-life of fenoprofen by increasing the metabolic clearance of hydroxylated fenoprofen. Chronic administration of phenobarbital also decreases the drug’s half-life.

Определение

ChEBI: Propanoic acid in which one of the hydrogens at position 2 is substituted by a 3-phenoxyphenyl group. A non-steroidal anti-inflammatory drug, the dihydrate form of the calcium salt is used for the management of mild to moderate pain and for the relief of p in and inflammation associated with disorders such as arthritis. It is pharmacologically similar to aspirin, but causes less gastrointestinal bleeding.

Общее описание

Fenoprofen (Nalfon), is rapidly absorbed orally, reachespeak plasma levels within 2 hours, and has a short plasmahalf-life (3 hours). It is highly protein bound, just like theother NSAIDs, thus caution is needed when it is used concurrentlywith other medications including hydantoins, sulfonamides,and sulfonylureas. It is recommended for RAand OA, at an oral dose of 300 to 600 mg for 3 or 4 timesper day, but not exceeding 3 g/d to avoid any serious side effects.It should be noted that in a comparison study of allNSAIDs, fenoprofen is the one that has been most closelyassociated with a rare acute interstitial nephritis.188 For mildto moderate pain relief, the recommended dosage is 200 mggiven every 4 to 6 hours, as needed.
