[Arterial hypertension in elderly patients, and difficulties in its treatment].

In treating elderly patients with hypertension, specific characteristics should be taken into account. These are related to general hemodynamics, renal function and neurohormonal systems. Medications are the same as those used in middle-aged hypertensive patients. In the elderly, management requires great caution because of maximum difficulties. Satisfactory clinical and biological tolerance is an essential goal. The best initial therapy seems to be a diuretic drug given in low dosages. Some patients may require addition of a central sympatholytic, a beta-blocking agent or a vasodilator.
