Effect of valasartan on the plasma level of calcitonin gene-related peptide in patients with essential hypertension / 解放军医学杂志

ABSTRACT

Objective To explore the effect of valasartan, an angiotensin Ⅱ type 1 (AT 1) receptor antagonist, on the plasma levels of calcitonin gene-related peptide (CGRP) in patients with essential hypertension. Methods 29 outpatients with essential hypertension were treated with valasartan 80mg/day for 6 weeks. 28 age-matched normal blood pressure people were taken as controls. The plasma levels of CGRP were measured in all patients before and after treatment and in controls. Results The plasma levels of CGRP in hypertensive patients were significantly lower than those in controls (minimal value 0.00 vs 39.95pg/ml; maximal value 24.07 vs 155.59pg/ml; P
