1 Our results suggest that capsaicin might induce CYP3A4 expression; thus, exposure to capsaicin may increase the metabolism of CYP3A4 substrate and potentially cause food-drug interactions. Capsaicin cytochrome P450 family 3 subfamily A member 4 Homo sapiens
2 Capsaicin induces CYP3A4 expression via pregnane X receptor and CCAAT/enhancer-binding protein beta activation. Capsaicin cytochrome P450 family 3 subfamily A member 4 Homo sapiens
3 However, the influence of capsaicin on CYP3A4, its involvement in drug metabolism, and the underlying mechanisms remain unclear. Capsaicin cytochrome P450 family 3 subfamily A member 4 Homo sapiens
4 METHODS AND RESULTS: Here, we examined the effect of capsaicin on CYP3A4 expression and the metabolism of CYP3A1 substrate, nifedipine in male Sprague-Dawley rats. Capsaicin cytochrome P450 family 3 subfamily A member 4 Homo sapiens
5 Capsaicin induced the enzymatic activity and expression of CYP3A4 in HepG2 cells. Capsaicin cytochrome P450 family 3 subfamily A member 4 Homo sapiens
6 Treatment with a human pregnane X receptor (hPXR) inhibitor reduced the inductive effects of capsaicin on CYP3A4 expression. Capsaicin cytochrome P450 family 3 subfamily A member 4 Homo sapiens
7 CONCLUSION: From these data, we conclude that capsaicin induces CYP3A4 expression in vitro and in vivo. Capsaicin cytochrome P450 family 3 subfamily A member 4 Homo sapiens
