due to inhibition of angiotensin II production by ACE inhibitors or competitive antagonism of the angiotensin II receptor by ARBs... results in loss of angiotensin II–induced efferent arteriolar tone, leading to a drop in glomerular filtration fraction and GFR. The efferent arteriolal vasodilation reduces intraglomerular hypertension (and pressure-related injury) and maintains perfusion (and oxygenation) of the peritubular capillaries.
In conclusion, we demonstrated regression of DAR using ARBs at moderate and supramaximal doses. Intensive ARB therapy offers a promise to reduce the natural progression of disease in patients with DARs.
The angiotensin II receptor antagonists, also known as angiotensin receptor blockers (ARBs), are a family of agents that bind to and inhibit the angiotensin II type 1 receptor (AT1) and thus inhibit the renin-angiotensin system and its cascade of effects in causing arteriolar contraction and sodium retention. While angiotensin converting enzyme (ACE) inhibitors block the cleavage of angiotensin I to angiotensin II, the active peptide that causes a pressor response, the ARBs inhibit its peripheral action.

12.3 Pharmacokinetics/ Absorption: Following oral administration, the systemic bioavailability of losartan is approximately 33%. Mean peak concentrations of losartan and its active metabolite are reached in 1 hour and in 3 to 4 hours, respectively. While maximum plasma concentrations of losartan and its active metabolite are approximately equal, the AUC (area under the curve) of the metabolite is about 4 times as great as that of losartan. A meal slows absorption of losartan and decreases its Cmax but has only minor effects on losartan AUC or on the AUC of the metabolite (≈10% decrease). The pharmacokinetics of losartan and its active metabolite are linear with oral losartan doses up to 200 mg and do not change over time.
