Abstract: The interaction between drugs and transport proteins, such as albumins, is a key factor in drug bioavailability. One of the techniques commonly used for the evaluation of the drug‐protein complex formation is fluorescence. This work studies the interaction of human serum albumin (HSA) with four non‐steroidal anti‐inflammatory drugs (NSAIDs) (ibuprofen, flurbiprofen, naproxen, and diflunisal) by monitoring the fluorescence quenching when the drug‐albumin complex is formed. Two approaches - the double logarithm Stern‐Volmer equation and the STAR program - are used to evaluate the binding parameters. The results are analyzed considering the bind‐ ing properties, determined by using other complementary techniques and the available structural information of albumin complexes with NSAID‐related compounds. Finally, this combined analysis has been synergistically used to interpret the binding of flurbiprofen to HSA.
