Objective

To compare plasma concentrations of acetylsalicylic acid (ASA) and its metabolites between genetic polymorphisms in the gene encoding for UDP-glucuronosyltransferase 1A6 (UGT1A6), an enzyme involved in ASA metabolism.

Methods

Five UGT1A6*1 and 4 UGT1A6*2 homozygote females were given 320 mg ASA once daily for 8 days. During the first and last day of treatment, several blood samples were taken over a 10-hour time period and analyzed for plasma levels of ASA and its main metabolites salicylic acid (SA) and salicyluric acid (SUA), using a validated HPLC method. The pharmacokinetic data were assessed with the Time Constant Approach and both genotypes were compared using the Mann-Whitney U test.

Results

ASA and SUA showed similar pharmacokinetic parameters in the two UGT1A6 genotypes. However, pharmacokinetic parameters for SA differed significantly: the mean area under the pharmacokinetic curve for the UGT1A6*1 and UGT1A6*2 homozygotes was 136 and 94 microg/ml.h (p = 0.04), and median C(max) was 23 and 17 microg/ml (p = 0.01), respectively.

Conclusion

In females receiving ASA, the presence of the UGT1A6*2 compared to the UGT1A6*1 homozygote genotype is associated with lower plasma levels of SA, indicating faster pharmacokinetics."xsd:string
