COX-2 0.13 μM (IC50) |
COX-1 7.5 μM (IC50) |
The COX-1:COX-2 selectivity ratios generally are established by comparing the IC50 for COX-1 to the IC50 for COX-2. The IC80 value more closely resembles the steady-state plasma drug concentration than does the IC50 value[1].The selectivity ratio for Firocoxib based on the IC80 values is 121 (IC80 of 0.36 μM and 43.6 μM for COX-2 and COX-1, respectively), indicating that selectivity for COX-2 is not reduced at concentrations higher than the IC50. Notably, Firocoxib concentrations that yield 80% to 95% inhibition of COX-2 produce < 20% inhibition of COX-1[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Pharmacokinetic properties of Firocoxib are determined after i.v. (2 mg/kg) and oral (3 mg/kg) administration in male cats. Firocoxib has moderate to high oral bioavailability (54% to 70%), low plasma clearance (4.7 to 5.8 mL/min/kg), and an elimination half-life of 8.7 to 12.2 hours[1].
