Studies on the Control of Hypertension by Hyphex

One hundred and six patients in malignant stages of hypertension were treated with continuous oral hexamethonium chloride and 1-hydrazinophthalazine. The courses of ten uremic individuals were unaffected. Twenty-eight discontinued therapy, three of whom survived two months. Sixty-eight nonuremic patients continued treatment and 54 are alive 15 to 36 months later; 17 who were azotemic have lived two to three years. Of the 14 who died, only three succumbed to hypertensive complications. Forty-six of the living patients have returned to full activity. Apparently the malignant stage of hypertension is reversible by drugs properly used to lower blood pressure and no longer need be the rapidly fatal disease that it has been in the past.
