The C3435T genetic polymorphism of the ABCB1 (MDR1) gene as a predictor of antihypertensive efficacy of losartan monotherapy in newly diagnosed arterial hypertension DOI: https://doi.org/10.18413/rrpharmacology.12.1057Abstract Introduction: Losartan, a selective angiotensin II receptor type 1 antagonist, is transported across cell membrane mediated by P-glycoprotein, the product of the ABCB1 (also known as MDR1) gene. The level of expression of this transporter protein is characterized by...
