Abstract
ABCB1 haplotypes were determined in 534 healthy Finnish volunteers, of whom 24 participated in a pharmacokinetic study on simvastatin and atorvastatin. The frequencies of occurrence of haplotypes c.1236T-c.2677T-c.3435T and c.1236C-c.2677G-c.3435C were 42.7 and 34.4%, respectively. The simvastatin acid AUC(0-12h) was 60% larger, the atorvastatin AUC(0-infinity) 55% larger, and the atorvastatin half-life 24% longer in subjects with the ABCB1 TTT/TTT genotype (n = 12) than in those with the CGC/CGC genotype (n = 12) (P

Abstract
The ABCG2 c.421C>A single-nucleotide polymorphism (SNP) was determined in 660 healthy Finnish volunteers, of whom 32 participated in a pharmacokinetic crossover study involving the administration of 20 mg atorvastatin and rosuvastatin. The frequency of the c.421A variant allele was 9.5% (95% confidence interval 8.1-11.3%). Subjects with the c.421AA genotype (n = 4) had a 72% larger mean area under the plasma atorvastatin concentration-time curve from time 0 to infinity (AUC(0-infinity)) than individuals with the c.421CC genotype had (n = 16; P = 0.049). In participants with the c.421AA genotype, the rosuvastatin AUC(0-infinity) was 100% greater than in those with c.421CA (n = 12) and 144% greater than in those with the c.421CC genotype. Also, those with the c.421AA genotype showed peak plasma rosuvastatin concentrations 108% higher than those in the c.421CA genotype group and 131% higher than those in the c.421CC genotype group (P
