Serum Albumin is a major carrier protein and its binding with drugs is important to examine the change in pharmacokinetic properties due to interaction amongst drugs. In the present study we have attempted to understand the relevant drug-drug interaction (DDI) between two common drugs viz, paracetamol, an anti-inflammatory and fluorouracil, an anti-cancer drug. In-vitro spectroscopic methods viz., fluorescence quenching and UV-vis absorption have been employed for the drug-bovine serum albumin (BSA) complexes studies. The binding parameters and quenching constants have been determined for BSA-Paracetamol and BSA-5Fluorouracil complex according to literature models. It is also predicted from the quenching studies that BSA-5Fluorouracil is a stronger complex than BSA-Paracetamol. On the other hand paracetamol can alter binding affinity of 5Fluorouracil towards BSA. Hence it becomes clear that although the drugs could be administered simultaneously but they influence each other's binding with protein in a concentration dependent fashion. Further these results also indicate that availability of free 5Fluorouracil in blood may increase in presence of paracetamol. © 2018 Author(s).
