Fexofenadine (FEX) is mainly eliminated from the liver into bile in unchanged form. We demonstrated previously that organic anion transporting polypeptide (OATP) 1B1 and OATP1B3 are involved in the hepatic uptake of FEX. However, little is known about the mechanisms controlling the hepatic efflux of FEX from the liver to bile and blood. In the present study, the involvement of hepatic efflux tr...
Second generation H1 antihistamines are considered first-line therapy for allergic rhinitis and chronic idiopathic urticaria, largely because of their nonsedating effects. Evaluating pharmacokinetic and pharmacodynamic parameters and clinical efficacy of a drug is important, but models to predict clinical efficacy are lacking. Receptor occupancy (RO), a predictor for human pharmacodynamics and ...
Reverse transcription-polymerase chain reaction (RT-PCR) and quantitative, competitive RT-PCR were used to examine the capability of rifampin to induce the expression of mRNA derived from multidrug resistance-1 (MDR1) and drug-metabolizing cytochrome P450 (P450) genes in the mononuclear fraction (lymphocytes) of human blood. A total of 50 healthy volunteers (age, 18-74) participated in two stud...
AIMS We assessed the drug interaction profile of fermented red ginseng with respect to the activity of major cytochrome (CYP) P450 enzymes and of a drug transporter protein, P-glycoprotein (P-gp), in healthy volunteers. METHODS This study was an open-label crossover study. The CYP probe cocktail drugs caffeine, losartan, dextromethorphan, omeprazole, midazolam and fexofenadine were administer...
