Aim: The aim of this study was to study the effect of celecoxib on agomelatine metabolism in vitro and in vivo.
Methods: Ten healthy male Sprague–Dawley rats were randomly divided into 2 groups: Group A (control group) and Group B (30 mg/kg celecoxib). Then a single dose of 20 mg/kg agomelatine was administered orally 30 min after administration of celecoxib. In an in vitro study, celecoxib with a series of concentrations was added to an incubation mixture containing recombinant human CYP2C9, human or rat liver microsomes to determine the half-maximal inhibitory concentration on the metabolism of agomelatine. Moreover, a mechanism study was performed to determine the inhibitory effect of celecoxib on CYP2C9.
Results: The results showed that a single dose of 30 mg/kg celecoxib significantly increased the area under the concentration-time curve and maximum concentration of agomelatine. In addition, celecoxib inhibited the metabolism of agomelatine in the in vitro studies, which was determined to be by a competitive mechanism on CYP2C9. Those results indicated that celecoxib has an inhibitory effect on the metabolism of agomelatine both in vivo and in vitro.
Conclusion: Thus, more attention should be paid when celecoxib is administered combined with agomelatine.
