1 Effects of the SLCO1B1*1B haplotype on the pharmacokinetics and pharmacodynamics of repaglinide and nateglinide. repaglinide solute carrier organic anion transporter family member 1B1 Homo sapiens
2 The aim of this study was to investigate whether the SLCO1B1*1B haplotype affects the pharmacokinetics and pharmacodynamics of repaglinide and nateglinide. repaglinide solute carrier organic anion transporter family member 1B1 Homo sapiens
3 Plasma repaglinide and nateglinide and blood glucose concentrations were measured for 7 h. RESULTS: The AUC(0-infinity) and Cmax of repaglinide were 32% (P=0.007) and 24% lower (P=0.056) in the individuals with the SLCO1B1*1B/*1B genotype than in those with the SLCO1B1*1A/*1A genotype. repaglinide solute carrier organic anion transporter family member 1B1 Homo sapiens
4 Plasma repaglinide and nateglinide and blood glucose concentrations were measured for 7 h. RESULTS: The AUC(0-infinity) and Cmax of repaglinide were 32% (P=0.007) and 24% lower (P=0.056) in the individuals with the SLCO1B1*1B/*1B genotype than in those with the SLCO1B1*1A/*1A genotype. repaglinide solute carrier organic anion transporter family member 1B1 Homo sapiens
5 The mean blood glucose concentration from 0 to 7 h after repaglinide intake was 10% higher in the SLCO1B1*1B/*1B participants than in the SLCO1B1*1A/*1A participants (P=0.007). repaglinide solute carrier organic anion transporter family member 1B1 Homo sapiens
6 The mean blood glucose concentration from 0 to 7 h after repaglinide intake was 10% higher in the SLCO1B1*1B/*1B participants than in the SLCO1B1*1A/*1A participants (P=0.007). repaglinide solute carrier organic anion transporter family member 1B1 Homo sapiens
7 CONCLUSION: The SLCO1B1*1B/*1B genotype is associated with reduced plasma concentrations of repaglinide, consistent with an enhanced hepatic uptake by OATP1B1, but has limited effects on the pharmacokinetics of nateglinide. repaglinide solute carrier organic anion transporter family member 1B1 Homo sapiens
