Abstract:
:In 80 patients with moderate hypertension the effects of nisoldipine 10 mg b.i.d., nifedipine 10 mg and 20 mg t.i.d., diltiazem 60 mg and 120 mg t.i.d., and verapamil 40 mg q.i.d. (all after single dose and 14 days' treatment) on blood pressure; hemodynamic parameters (cardiac output, stroke volume, left ventricular ejection fraction, and total peripheral resistance); and red blood cell and platelet functional state parameters (platelet aggregation, erythrocytal mechanical resistance, and free hemoglobin and ADP levels in plasma) were studied. All of the drugs studied in doses mentioned produced statistically significant hypotensive effects. Nifedipine 20 mg and nisoldipine 10 mg produced the most peripheral vasodilatator activity after a single dose and chronic treatment. Diltiazem had the same effect only in doses of 120 mg and after chronic treatment. However, all the drugs significantly normalized the red blood cell and platelet functional state disturbances in 70-80% of patients with moderate hypertension, even 2 h after a single dose. Disaggregation effect was parallel to clinical improvement. These data make it possible to predict the individual response of most patients to antihypertensive drugs on the basis of acute pharmacological tests, with determination of disaggregation effect.
