Dup 753 prevents the development of puromycin aminonucleoside-induced nephrosis

The appearance of nephrotic syndromes such as proteinuria, hypoalbuminemia, hypercholesterolemia and increase in blood nitrogen urea, induced in rats by injection of puromycin aminonucleoside was markedly inhibited by oral administration of Dup 753 (losartan), a novel angiotensin II receptor antagonist, at a dose of 1 or 2 mg/kg per day. The results suggest a possible involvement of the renin-angiotensin system in the development of puromycin aminonucleoside-induced nephrosis.
