Abstract:
OBJECTIVE(S):To study the changes in macrophage inducible nitric oxide synthase (iNOS) activity, plasma levels of nitrite, lipid peroxidation (LPO) and melatonin in human essential hypertension before and 6 months after 4 mg/day lacidipine treatment. DESIGN:The study was carried out in a total of 25 subjects--11 healthy subjects and 14 hypertensive patients. Blood pressure and peripheral blood samples were taken before and after 6 months of lacidipine treatment (4 mg/day). METHODS:Systolic (SBP) and diastolic blood pressure (DBP), renal function, lipid and carbohydrate metabolism, renin, aldosterone and catecholamine levels were measured by routine methods. The activity of macrophage iNOS and plasma nitrite, LPO and melatonin levels were also measured. CONCLUSIONS:Besides reducing blood pressure, lacidipine treatment significantly decreased plasma LPO and macrophage iNOS activity, without changes in NO. Melatonin significantly increases in hypertensive patients, returning to control after lacidipine. Thus, lacidipine reduced blood pressure and free radicals, avoiding the oxidative damage to endothelium. It is suggested that administration of lacidipine plus melatonin may enhance the beneficial effects of each drug in essential hypertension.
