Evaluation of

To evaluate applicability of , and based algorithm to predict warfarin stable dose (WSD) in a group of Palestinian patients. Warfarin doses were retrospectively calculated for 101 Palestinian patients under warfarin therapy using three models. Performance of the three models was assessed in 47 patients found to take WSD. Frequency of , and alleles is 13.6, 0.0 and 46.5% respectively. The international warfarin pharmacogenetics consortium algorithm was more reliable (MAE = 8.9 ± 1.4; R = 0.350) than both the clinical algorithm (MAE = 10.4 ± 1.4; R = 0.128;) and the fixed-dose algorithm (MAE = 11.1 ± 1.7). The international warfarin pharmacogenetics consortium algorithm can be reliably applied for predicting the WSD in Palestinian population. The aim of this study was to evaluate applicability of an algorithm that is based on the patient genotype to predict the warfarin stable dose in a group of Palestinian patients. The international warfarin pharmacogenetics consortium algorithm was more reliable than both a clinical algorithm and a fixed-dose algorithm. The international warfarin pharmacogenetics consortium algorithm can be reliably applied for predicting the warfarin stable dose in Palestinian population.
