1 Differential inhibition of the prejunctional actions of angiotensin II in rat atria by valsartan, irbesartan, eprosartan, and losartan. Valsartan angiotensinogen Rattus norvegicus
2 Pretreatment of tissues with valsartan, irbesartan, eprosartan, or losartan (10(-8) to 10(-6) M) produced concentration-dependent inhibitions of the stimulation-induced efflux of radioactivity observed in the presence of angiotensin II (10(-7) M). Valsartan angiotensinogen Rattus norvegicus
3 Thus, valsartan is a potent inhibitor of the prejunctional facilitatory effect of angiotensin II on the release of norepinephrine from peripheral sympathetic nerves. Valsartan angiotensinogen Rattus norvegicus
4 This implies that the therapeutic domain of valsartan may be extended to include pathophysiological conditions such as congestive heart failure wherein prejunctional angiotensin II receptors apparently play a significant role. Valsartan angiotensinogen Rattus norvegicus
