Abstract
Background: Resveratrol (RSV) is a polyphenol belonging to phytoalexin family and has been reported to show inhibitory effects on CYP3A4 enzymes. However, there has been no report about the pharmacokinetic interaction of bromocriptine (BRO) with RSV and RSV nanoparticles (NRSV) in rats. Hence, the present study was undertaken in an attempt to enhance the oral bioavailability of BRO when BRO was pretreated with RSV and NRSV. Materials and Methods: Antisolvent precipitation method is used to prepare NRSV under temperature control. The following methods were used in this study, i.e., in vitro assessment of CYP3A activity in liver and intestinal microsomes and in vitro noneverted sac method. To confirm the in vitro findings, an in vivo pharmacokinetic study was also performed. Results: The results indicate that RSV significantly (P
