Diclofenac is an extensively used nonsteroidal anti-inflammatory drug, but gastrointestinal liabilities and cardiovascular complications take the shine away from such a widely prescribed drug. On the other hand, rutin, a dietary bioflavonoid, has quite a few pharmacological attributes to improve the efficacy and reduce the dose-related toxicities of diclofenac through the intended food-drug/herb-drug interaction. The aim of the present research work was to investigate the role of rutin on pharmacokinetic modulation and the consequent efficacy of diclofenac. At first, pharmacodynamics and pharmacokinetics of diclofenac as alone and in the presence of rutin were investigated orally in a rat model. Then, mechanistic studies were performed to explain the effect of rutin on improvement in oral exposure as well as the efficacy of diclofenac using a battery of in-vitro/in-situ/in-vivo studies. Results displayed that rutin enhanced efficacy as well as oral bioavailability of diclofenac in rats. A marked increase in permeability of diclofenac by rutin was displayed that is linked to inhibition of Breast Cancer Resistance Protein (BCRP) transporters. There was no significant effect of rutin on the modulation of intestinal transit, CYP2C9 inhibition in human liver microsomes, and CYP2C9/CYP2C11 expression in rat liver tissues to boost the oral exposure of diclofenac. Rutin is found to be an inhibitor for BCRP transporters and can act as an oral bioavailability enhancer for a drug like diclofenac.

D000070997 ATP Binding Cassette Transporter, Subfamily G, Member 2 ATP-binding cassette transporter, sub-family G protein that functions as a high capacity UREA exporter, transporter of STEROLS, and in the absorption and efflux of many drugs. Its efflux activity for ANTINEOPLASTIC AGENTS contributes to DRUG RESISTANCE. It functions as a homodimer and is expressed by cells in a variety of organs, as well as by NEOPLASTIC STEM CELLS.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000894 Anti-Inflammatory Agents, Non-Steroidal Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.
