“At the relevant total and free drug concentrations, the inhibitory effect of oleic acid on drug binding and its influence on drug-induced displacement of T4 were concordant in the order: meclofenamic acid greater than aspirin greater than mefenamic acid greater than diflunisal greater than furosemide greater than fenclofenac.”
“Increments in added oleic acid (0.5-2.0 mmol/L) progressively increased the mean unbound fractions of [14C]aspirin, [14C] diflunisal , and [14C]furosemide, but did not displace [14C]fenclofenac.”
“ Oleic acid (1 mmol/L) alone did not inhibit serum protein binding of T4, but this concentration augmented the inhibitory effects on T4 binding of diflunisal , mefenamic acid, meclofenamic acid, and aspirin.”
