The effects of two different H2-receptor antagonists, cimetidine and famotidine, on the acute renal failure induced by 20 min of renal artery occlusion and gentamicin (240mg/kg BW, s. c., for 3 days) were investigated in Sprague-Dawley rats. The animals were treated with either cimetidine (80 or 160 mg/kg BW) or famotidine (4 or 8 mg/kg BW) mixed in the drinking water for 7 days. The low dose of cimetidine and famotidine did not alter the renal function in the absence of renal trauma. However, the high dose of cimetidine or famotidine decreased the GFR by 32% and 22%, whereas RPFR increased by 46% and 62%, and % FENa by 92% and 558%, respectively. The data for the renal function obtained 24 hrs after 20 min of renal ischemia demonstrated a decrease of 54% in GFR, a decrease of 47% in RPFR and an increase of 370% in %FENa over the non-ischemic control values (p less than 0.05). Cimetidine (80 mg/kg BW) or famotidine (4 mg/kg BW) did not modify the recovery of renal function following the ischemic insult, showing 55% and 539% decreases in GFR, 74% and 101% increases in RPFR, and 393% and 461% increases in %FENa over the non-ischemic control rats, respectively. Famotidine reduced the decrease in RPFR significantly during the recovery period following ischemia. In the gentamicin study, gentamicin treatment was found to lower the renal function significantly.(ABSTRACT TRUNCATED AT 250 WORDS)
