Pimozide 54-62 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 129-134 9951426-2 1999 We recently reported 2 fatal cases in patients taking pimozide and clarithromycin and we have shown that clarithromycin inhibits CYP3A-mediated metabolism of pimozide in vitro. Pimozide 158-166 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 129-134 9951426-13 1999 Clarithromycin inhibited CYP3A-mediated pimozide metabolism and the resulting elevation in plasma concentrations may increase the risk of pimozide cardiotoxicity. Pimozide 40-48 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 25-30 9951426-13 1999 Clarithromycin inhibited CYP3A-mediated pimozide metabolism and the resulting elevation in plasma concentrations may increase the risk of pimozide cardiotoxicity. Pimozide 138-146 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 25-30 9580580-7 1998 The formation rate of DHPBI from 25 microM pimozide in nine human livers correlated significantly with the catalytic activity of CYP3A (Spearman r = 0.79, P = .028), but not with other isoforms. Pimozide 43-51 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 129-134 9580580-9 1998 Recombinant human CYP3A4 catalyzed DHPBI formation from 10 microM pimozide at the highest rate (V = 2.2 +/- 0.89 pmol/min/pmol P450) followed by CYP1A2 (V = 0.23 +/- 0.08 pmol/min/pmol P450), but other isoforms tested did not. Pimozide 66-74 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 18-24 9580580-11 1998 Pimozide itself was a potent inhibitor of CYP2D6 in HLMs when preincubated for 15 min (Ki = 0.75 +/- 0.98 microM) and a moderate inhibitor of CYP3A (Ki = 76.7 +/- 34.5 microM), with no significant effect on other isoforms tested. Pimozide 0-8 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 142-147 9580580-12 1998 Our results suggest that pimozide metabolism is catalyzed mainly by CYP3A, but CYP1A2 also contributes. Pimozide 25-33 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 68-73 9580580-13 1998 Pimozide metabolism is likely to be subject to interindividual variability in CYP3A and CYP1A2 expression and to drug interactions involving these isoforms. Pimozide 0-8 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 78-83 25868121-4 2015 Aripiprazole, haloperidol, pimozide, and risperidone are antipsychotics that are metabolized by CYP3A4 and CYP2D6.

Pimozide 63-71 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 24-30 32847865-2 2020 Prior in vitro studies characterized N-dealkylation of pimozide to 1,3-dihydro-1-(4-piperidinyl)-2H-benzimidazol-2-one (DHPBI) via CYP3A4, and to a lesser extent CYP1A2, as the only notable routes of pimozide biotransformation. Pimozide 55-63 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 131-137 32847865-2 2020 Prior in vitro studies characterized N-dealkylation of pimozide to 1,3-dihydro-1-(4-piperidinyl)-2H-benzimidazol-2-one (DHPBI) via CYP3A4, and to a lesser extent CYP1A2, as the only notable routes of pimozide biotransformation.
