Nortriptyline 0-13 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 90-96 17662092-9 2008 As a representative TCA, nortriptyline fulfilled the in vitro MBI criteria using recombinant CYP2C19 and CYP3A4 (K(I) and k(inact) values of 4 microm and 0.19 min(-1), and 70 microm and 0.06 min(-1)), but not with the human liver microsomal enzymes. Nortriptyline 25-38 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 105-111 21854846-10 2011 The results point towards the combination of low CYP3A4 activity and CYP2D6 PM status of major importance for attaining possibly toxic nortriptyline concentrations. Nortriptyline 135-148 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 49-55 21854846-12 2011 In a clinical context, the simulations suggest that precise individual dose adjustment of nortriptyline requires information regarding the activity of both CYP3A4 and CYP2D6. Nortriptyline 90-103 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 156-162 10354960-7 1999 A simulation of the relative contribution of CYPs 2D6 and 3A4 to net nortriptyline hydroxylation rate suggested that the relative contribution of CYP3A4 is only 20% even at the higher end of the therapeutic range. Nortriptyline 69-82 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 146-152 10354960-9 1999 The identification of CYP3A4 as a low-affinity nortriptyline E-10-hydroxylase explains the ability of poor metabolizers of debrisoquin to hydroxylate nortriptyline, as well as the increased in vivo clearance via this pathway caused by CYP3A4-inducing drugs such as pentobarbital, carbamazepine, and rifampin. Nortriptyline 47-60 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 22-28 10354960-9 1999 The identification of CYP3A4 as a low-affinity nortriptyline E-10-hydroxylase explains the ability of poor metabolizers of debrisoquin to hydroxylate nortriptyline, as well as the increased in vivo clearance via this pathway caused by CYP3A4-inducing drugs such as pentobarbital, carbamazepine, and rifampin.
