Valsartan methyl ester is an orally active antagonist for angiotensin II , that inhibits angiotensin II ( IC 50 of 0.06 μM), angiotensin II-induced pressor response in rabbit aorta ( IC 50 of 0.068 μM) and angiotensin II-induced pressor response in the pithed rat model (10% inhibition at 10 mg/kg, p.o.).
