Abstract excerpt
OBJECTIVE: Our objective was to quantitate the contribution of the genetic polymorphism of the human MDR1 gene to the bioavailability and interaction profiles of digoxin, a substrate of P-glycoprotein. METHODS: The pharmacokinetics of digoxin was studied in 15 healthy volunteers, who were divided into 3 groups (n = 5 each) on the basis of genotyping for the MDR1 gene, in a 4-dose study after single doses of...
