RT Journal Article SR Electronic A1 Cunningham, Muriel T1 EU-PACT Study: Initial Warfarin Dosing Improved by Clinical Variables and Genotype to Guide Therapy JF MD Conference Express YR 2013 FD SAGE Publications VO 13 IS 20 SP 19 OP 19 DO 10.1177/155989771320009 UL http://mdc.sagepub.com/content/13/20/19.abstract AB Response to warfarin is highly variable, making it difficult to select the optimal dose. Typical doses can range from 0.5 to 20 mg per day, and various factors, such as genetics, can influence an individual's daily dose. The purpose of the European Union Pharmacogenetics of Anticoagulant Therapy Warfarin Study [EU-PACT; Pirmohamed M et al. N Engl J Med 2013] was to compare whether the use of clinical variables and genotype information improves the time in therapeutic range compared with “standard” dosing.
