1 While ramiprilat itself induced an increase of basal [Ca2+]i, the Ca(2+)-mobilizing effect of angiotensin II (AII) was blunted in the presence of the ACE inhibitor (659 +/- 38 nM vs 360 +/- 45 nM, p less than .001). ramiprilat angiotensinogen Homo sapiens
2 Ramiprilat-induced contraction of cultured smooth muscle cells may not be relevant in vivo, but the increase of basal [Ca2+]i by ramiprilat may reflect a "reset" of the cellular Ca(2+)-mobilizing mechanism or a depletion of cellular Ca2+ stores and may thus explain the attenuation of the Ca(2+)-mobilizing effect of AII. ramiprilat angiotensinogen Homo sapiens
