Hypoxia-induced tubulointerstitial injury caused by loss of peritubular capillary (PTC) blood flow may be associated with progressive renal disease. Therefore, the maintenance of blood flow in PTCs may protect against loss of renal function. A long-acting calcium channel blocker, azelnidipine, has been shown to be useful in the treatment of progressive renal disease. However, its mechanism of action remains unclear. The aim of the present study was to elucidate whether azelnidipine maintains PTC blood flow and to compare it to nifedipine in its ability to improve tubulointerstitial injury caused by angiotensin II (AII) infusion in rats.
