Cimicoxib
Based on 1 Customer Validation
Cimicoxib (UR-8880) is an orally active, blood-brain barrier-permeable COX-2 inhibitor that also exerts targeted inhibition on CYP2D15. It has an IC50 of 66 nM against hCOX-2, an IC50 of 1.6 μM against canine CYP2D15, and an IC50 of 0.056 μM against feline CYP2D15. By inhibiting the COX-2 pathway to reduce the production of thromboxane B2 and prostaglandin E2, Cimicoxib exerts antipyretic, anti-inflammatory and analgesic effects. Cimicoxib is metabolized by CYP2D15 to form demethyl-cimicoxib, undergoes glucuronidation via UDP-glucuronosyltransferases, and exhibits biphasic elimination kinetics in beagle dogs. Cimicoxib is widely used in studies of inflammatory diseases, osteoarthritis, and perioperative pain associated with orthopedic or soft tissue surgeries.

Cimicoxib (15 μM; 30 min) undergoes phase 1 metabolism to form demethyl-cimicoxib in feline hepatic microsomes, with CYP2D15 as the primary metabolizing enzyme and CYP3A12 contributing to a lesser extent, and has lower affinity for feline CYP2D15 orthologs than for canine CYP2D15[2].

Cimicoxib (1 mg/kg; i.v.; single slow bolus injection) administered as a single 1 mg/kg i.v. bolus in healthy European crossbreed cats has a total body clearance of 0.13 L/h kg, a terminal half-life of 5.16 h, and 3.32% of the dose is eliminated in urine with conjugated demethyl-cimicoxib representing the majority of urinary metabolites[2].
Cimicoxib (2 mg/kg; p.o., i.v.; single dose) exhibits significant antipyretic, anti-inflammatory, and analgesic efficacy in beagle dogs with kaolin-induced paw inflammation, with EM dogs requiring lower plasma concentrations for half-maximal effects and PM dogs demonstrating longer effect durations[3].
Cimicoxib (2-5 mg/kg; p.o. via nasogastric tube; single dose) produces mean maximal COX-1 inhibition of 62.4% (fasted) and 54.6% (fed), and mean maximal COX-2 inhibition of 72.1% (fasted) and 68.5% (fed) in healthy mares at the 5 mg/kg dose, while the 2 mg/kg dose yields detectable plasma concentrations but no reported specific inhibition values[4].
