[Use of foridon in the treatment of arterial hypertension and hypertension of the lesser circulation].

Hypotensive effect of foridon was evaluated in 68 patients with first- and second-stage essential hypertension, 17 patients with renal hypertension and 18 patients with pulmonary hypertension. Changes in clinical condition, central hemodynamics, pulmonary arterial systolic pressure, inhalation and exhalation intensity were assessed. Foridon effect was shown to be largely due to reduced peripheral resistance.
