Antihypertensive Effect of Debrisoquin Sulfate in the Treatment of Hypertension

Authors observed the antihypertensive effect of debrisoquin sulfate in 35 cases of essential hypertension and following results were obtained. 1) Results of short term control of blood pressure with debrisquin in 35 hypertensive patients revealed good control in 74.3%, fair in 14.3%, poor in 5.7% and failure in 5.7% of cases. Significant reduction of blood pressure was achieved in 7 of 9 cases of hypertension with addition of hydrochlorthiazide to debrisoquin. 2) During long term therapy with debrisoquin (duration of average 3.9 months), good control cases were slightly reduced(good in 58.6%, fair in 24.1%, poor in 6.9%, failure in 10.3%). But average effective dose of debriioquin was not increased significantly. 3) Antihypertensive effect of debrisoquin was slightly reduced in the cases of severe hypertension, hypertension of over 10 years duration and complication of cerebrovascular accident. 4) The side effects during treatment with debrisoquin were dizziness in 31.4%, headache in 11.4%, dry mouth, blurred vision, general weakness, insomnia in 8.6% respectively. There were no side effects in 48.6% of cases.

Clinical Studies on Idiopathic Myocardiopathy

Twenty-two cases of idiopathic myocardiopathy were observed during the period of 1962 to 1971 and follow up clinical study was made in 5 cases. The criteria of diagnosis was based mainly on exclusive diagnosis in etiology unknown marked cardiomegaly. 1) Male and female ratio of idiopathic myocardiopathy was 1.1:1 and age of onset were distributed from first decade to fifth decade with similar number of cases. 2) Cardinal symptoms were dyspnea, palpitation, chest pain and cough. Common physical findings were protodiastolic gallop (in 2 cases), moist rales (in 3 cases) and hepatomegaly(in 3 cases). 3) Laboratory findings were normal except elevated T.T.T. in one case. 4) Electrocardiogram were abnormal in all cases. There were 3 cases of left ventricular hypertrophy, 3 cases of non-specific ST-T changes and one case of first degree A-V block, intraventricular conduction defect, abnormal Q wave and low valtage, respectively. 5) After medical treatment, symptoms were improved in 4 cases but heart size was reduced in only one case and E.C.G. abnormalities were unchanged in all cases.
