Ace inhibitors and arbs cause decrease in gfr. Then why do we use telmisartan in chronic renal failure here?

ACEI/ARB doesn’t decrease GFR significantly… The decrease in filtration pressure is compensated by increased renal plasma flow. Only the filtration fraction is decreased

Its question related to the excretion of drug here you have to rule out the one which does not get excreted through the renal system
