体外研究 | The COX-1:COX-2 selectivity ratios generally are established by comparing the IC 50 for COX-1 to the IC 50 for COX-2. The IC 80 value more closely resembles the steady-state plasma drug concentration than does the IC 50 value.The selectivity ratio for Firocoxib based on the IC 80 values is 121 (IC 80 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 IC 50 . Notably, Firocoxib concentrations that yield 80% to 95% inhibition of COX-2 produce < 20% inhibition of COX-1. |
