Saprisartan is an AT1 receptor antagonist. It is based on medications of losartan's prototypical chemical structure. The mode of (functional) AT1 receptor antagonism has been characterized as insurmountable/noncompetitive for saprisartan. It is very likely that slow dissociation kinetics from the AT1 receptor underlie insurmountable antagonism.(10579749)
Indication
Saprisartan is used in the treatment of hypertension and heart failure.
Pharmacology
By inhibiting the angiotensin II receptor, this drug leades to a decrease in sodium reabsorption and a decrease in vasoconstriction. This has the combined effect of decreasing blood pressure.
