Lornoxicam-d4

Lornoxicam-d4 is intended for use as an internal standard for the quantification of lornoxicam (Cay-70220) by GC- or LC-MS. Lornoxicam is a COX inhibitor and non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory and analgesic properties. It inhibits production of thromboxane B2 (TXB2, Cay-19030) from arachidonic acid (Cay-90010, Cay-90010.1, Cay-10006607) in HEL human erythroleukemic cells (IC50 = 3 nM), which endogenously express COX-1, as well as inhibits LPS-induced formation of prostaglandin F1alpha (PGF1alpha, Cay-15010) from arachidonic acid in Mono-Mac-6 cells (IC50 = 8 nM), which endogenously express COX-2. Lornoxicam reduces LPS-induced production of nitric oxide and IL-6 in cell-based assays with IC50 values of 65 and 54 µM, respectively. It reduces carrageenan-induced paw edema in rats when administered intravenously at doses ranging from 0.1 to 9 mg/kg. Formulations containing lornoxicam have been used in the management of postoperative pain.Formal Name: 6-chloro-4-hydroxy-2-methyl-N-2-pyridinyl-d4-2H-thieno[2,3-e]-1,2-thiazine-3-carboxamide-1,1-dioxide.
