The chemical name for carprofen, a substi- tuted carbazole, is (±)-6-chloro-α-methylcarbazole-2-acetic acid and its structural formula is: Carprofen is a white, crystalline compound with an empirical formula of C 15 H 12 NO 2 Cl and a molecu- lar weight of 273.72. It is freely soluble in ethanol, but practically insoluble in water at 25°C. CLINICAL PHARMACOLOGY: Carprofen is a non-narcotic, non-steroidal anti-inflammatory agent with characteristic analgesic and antipyretic activity approximately equipotent to indomethacin in animal models. 1 The mechanism of action of carprofen, like that of other NSAIDs, is believed to be associated with the inhibition of cyclooxygenase activity. Two unique cyclooxygenases have been described in mammals. 2 The constitutive cyclooxygenase, COX-1, synthesizes prostaglandins necessary for normal gastrointestinal and renal function. The inducible cyclooxygenase, COX-2, generates prosta- glandins involved in inflammation. Inhibition of COX-1 is thought to be associated with gastrointesti- nal and renal toxicity while inhibition of COX-2 provides anti-inflammatory activity. The specificity of a particular NSAID for COX-2 versus COX-1 may vary from species to species. 3 In an _in vitro_ study using canine cell cultures, carprofen demonstrated selective inhibition of COX-2 versus COX-1. 4 Clinical relevance of these data has not been shown. Carprofen has also been shown to inhibit the release of several prostaglandins in two inflammatory cell systems: rat polymorphonuclear leukocytes (PMN) and human rheumatoid synovial cells, indi- cating inhibition of acute (PMN system) and chronic (synovial cell system) inflammatory reactions. 1 Several studies have demonstrated that carprofen has modulatory effects on both humoral and cel- lular immune responses. 5–9 Data also indicate that carprofen i Прочитать полный документ
