Influence of Resveratrol on the Pharmacokinetics and Pharmacodynamics of Naproxen: Involvement of CYP1A2 Inhibition
The purpose of the present study was to assess the effect of resveratrol (RSV) on the pharmacokinetics of naproxen (NAP) in rats. A single dose of RSV 30mg/kg was administered once during treatment phase. A single dose of NAP 25mg/kg was administered after RSV treatment. The blood samples were collected after NAP dosing at predetermined time intervals and analyzed by HPLC. In comparison with the control, RSV pretreatment significantly enhanced maximum plasma concentration (Cmax), area under the curve (AUC), and half life (t1/2) and significantly decreased apparent oral clearance (CL/F) and apparent volume of distribution (Vd/F), while there was no significant change observed in time to reach maximum concentration (tmax) of NAP. The results suggest that the altered pharmacokinetics of NAP might be attributed to RSV-mediated inhibition of CYP1A2 enzyme. Therefore, combination therapy of NAP along with RSV may represent a novel approach to reduce dosage and results in reduced gastrointestinal side effects of NAP.
