Abstract/OtherAbstract:
This study analysed and compared the effects of chronic oral treatment with quercetin or verapamil on systolic blood pressure and vascular function in deoxycorticosterone acetate (DOCA)-salt hypertensive rats. Quercetin and verapamil inhibited the development of DOCA-salt-induced hypertension in a similar manner. DOCA-salt-hypertensive rats showed potassium depletion and oxidative stress, prevented only by concomitant quercetin administration. Quercetin and verapamil treatments reduced the endothelium-independent hyper-reactivity to KCl observed in the aorta of DOCA-salt-hypertensive rats, but only quercetin increased the contractile responses to angiotensin II, improved endothelial dysfunction and restored basal aortic Cu/Zn SOD expression, altered in DOCA-salt-treated rats. In conclusion, quercetin and verapamil show similar antihypertensive effects in mineralocorticoid hypertension, but quercetin was superior to verapamil in improving endothelial-dependent aortic dilatation, suggesting a better vascular protection in this volume expansion hypertension model.
