Modulation of human BCRP (ABCG2) activity by anti-HIV drugs.
OBJECTIVES The safety and effectiveness of highly active antiretroviral therapy (HAART) is challenged by viral resistance to antiretrovirals and the frequent occurrence of drug interactions which mayExpand
Inhibition of P-Glycoprotein by Newer Antidepressants
Pharmacokinetic drug-drug interactions often occur at the level of P-glycoprotein (Pgp). To study possible interactions caused by the newer antidepressants we investigated citalopram, fluoxetine,Expand
Inhibition of MRP1/ABCC1, MRP2/ABCC2, and MRP3/ABCC3 by Nucleoside, Nucleotide, and Non-Nucleoside Reverse Transcriptase Inhibitors
Many drug interactions with drugs used for the therapy of human immunodeficiency virus (HIV) occur at the level of different cytochrome P450 isozymes. Increasing evidence suggests thatExpand
Expression of the drug transporters MDR1/ABCB1, MRP1/ABCC1, MRP2/ABCC2, BCRP/ABCG2, and PXR in peripheral blood mononuclear cells and their relationship with the expression in intestine and liver.
ATP binding cassette (ABC)-transporters like P-glycoprotein (multidrug resistance (MDR)1/ABCB1), the multidrug resistance associated proteins 1 and 2 (MRP1/ABCC1 and MRP2/ABCC2), and the breastExpand
CYP2C19 Genotype Is a Major Factor Contributing to the Highly Variable Pharmacokinetics of Voriconazole
In vitro data on the metabolism of the antifungal voriconazole suggest that its pharmacokinetics might be influenced by the activity of CYP2C19, CYP2C9, and CYP3A. To elucidate the genetic influenceExpand
Pharmacokinetics, metabolism and bioavailability of the triazole antifungal agent voriconazole in relation to CYP2C19 genotype.
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT * Pharmacokinetic variability of voriconazole is largely caused by CYP3A4- and CYP2C19-mediated metabolism. * Oral bioavailability of voriconazole has beenExpand
Localization of the Human Breast Cancer Resistance Protein (BCRP/ABCG2) in Lipid Rafts/Caveolae and Modulation of Its Activity by Cholesterol in Vitro
Breast cancer resistance protein (BCRP/ABCG2) is an active efflux pump that belongs to the ATP-binding cassette (ABC) transporter family. It is located in various tissues involved in drug absorption,Expand
Opposite effects of short‐term and long‐term St John's wort intake on voriconazole pharmacokinetics
Constituents of St John's wort (SJW) in vivo induce the cytochrome P450 (CYP) isozymes 3A4, 2C9, and 2C19 but in vitro were shown to inhibit them. This study investigates both short‐ and long‐termExpand
Understanding variability with voriconazole using a population pharmacokinetic approach: implications for optimal dosing.
OBJECTIVES Voriconazole exhibits highly variable, non-linear pharmacokinetics and is associated with a narrow therapeutic range. This study aimed to investigate the population pharmacokinetics ofExpand
Comparison of the inhibitory activity of anti-HIV drugs on P-glycoprotein.
Human immunodeficiency virus 1 (HIV-1) infections are treated with HIV-protease inhibitors (PIs), nucleoside (NRTIs), non-nucleoside (NNRTIs), and nucleotide reverse transcriptase inhibitorsExpand
