| 1 | Maximal plasma concentrations of diclofenac after oral administration of aceclofenac (0.39 micromol/L) or diclofenac (1.28 micromol/L) were sufficient for a greater than 97% inhibition of COX-2 (50% inhibitory concentration, 0.024 micromol/L) and a 46% (aceclofenac treatment) or 82% inhibition (diclofenac treatment) of COX-1 (50% inhibitory concentration, 0.43 micromol/L). | aceclofenac | mitochondrially encoded cytochrome c oxidase II | Homo sapiens |
| 2 | Although 100 mg aceclofenac yielded diclofenac concentrations substantially lower than 75 mg diclofenac, these were sufficient for a sustained block of COX-2 but caused a minor and shorter inhibition of COX-1 than 75 mg diclofenac. | aceclofenac | mitochondrially encoded cytochrome c oxidase II | Homo sapiens |
| 3 | In conclusion, both COX-1-sparing and COX-2-inhibitory actions of aceclofenac may rest in its limited but sustained biotransformation to diclofenac. | aceclofenac | mitochondrially encoded cytochrome c oxidase II | Homo sapiens |
