Effects of Resveratrol Co-Administration on Celecoxib Disposition and Pharmacokinetics in Healthy Volunteers.

The objective of the current study was to investigate the effects of resveratrol (RSV), a natural herbal remedy used as an adjacent anti-inflammatory supplement on, the pharmacokinetics of celecoxib in healthy male volunteers. Twelve healthy human participants were involved in two-period open-labeled trial. Celecoxib (200 mg) was given as a single oral dose under fasting conditions as a control phase. Afterward, RSV (500 mg) commenced as a single oral dose for ten days as a treatment phase. Blood samples were collected during the control and treatment phases and analyzed using the validated High-performance liquid chromatography (HPLC) method. RSV pre-exposure significantly increased the area under the curve (AUC0-24 ), peak plasma concentration (Cmax ), absorption rate constant (ka), and prolongated half-life (t1/2 ), along with a decrease in elimination rate constant (ke). Meanwhile, the volume of distribution (Vd/F) and apparent total body clearance (CL/F) were significantly decreased for celecoxib. There was no significant change in the time it takes for celecoxib to reach the maximum concentration (tmax ) was observed. The obtained results suggested the presence of a beneficial pharmacokinetic interaction between RSV and celecoxib. Consequently, combining resveratrol as an herbal remedy and celecoxib as an anti-inflammatory drug may synergistically reduce inflammation and osteoarthritis with minimal side effects.
