1 Moreover, ex vivo COX-1-dependent thromboxane B(2) synthesis was inhibited significantly less by aceclofenac than by diclofenac. aceclofenac mitochondrially encoded cytochrome c oxidase I 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 I 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 I Homo sapiens
