Abstract:
Aim of the work was selection of optimal for patients in Russia algorithm of warfarin dosing based on results of pharmacogenomic testing. We analyzed data from 78 patients aged 63.4+/-9.4 years with known CYP29 and VKORC1 genotypes who had participated in an earlier retrospective study in which they received warfarin according to traditional scheme with starting dose of 5 mg/day. We used 5 known algorithms of determination of initial warfarin dose based on results of pharmacogenomic testing and correlated calculated doses with those which had been actually selected in our patients. Correlation was closest for doses obtained with algorithm of Gage et al (www.warfarindosing.org) (r=0.887, p<0.0001). Therefore we consider this algorithm most suitable for patients in Russia.
