1 Employing primary cultures of human hepatocytes, they compared the CYP3A4 inductive effects of efavirenz (1-10 microM) to rifampin (10 microM) and phenobarbital (2 mM). efavirenz cytochrome P450 family 3 subfamily A member 4 Homo sapiens
2 The authors observed that efavirenz caused a concentration-dependent CYP3A4 induction and hPXR activation. efavirenz cytochrome P450 family 3 subfamily A member 4 Homo sapiens
3 Based on the CYP3A4 activity assay, the average magnitude of induction by efavirenz (5-10 microM) was approximately 3- to 4-fold. efavirenz cytochrome P450 family 3 subfamily A member 4 Homo sapiens
