Abstract:
:The hypotensive effect of isradipine was assessed in 26 male patients, aged 40 to 64 years, with hypertension. After withdrawal of previous antihypertensive treatment and a four-week placebo period, patients were randomized into a double-blind active-treatment period of eight weeks to receive either placebo or 1.25 to 2.5 mg isradipine twice daily. Twenty-four-hour ambulatory blood pressure was measured by Accutracker (Suntech, Oxford, England) after the placebo period and at the end of the active-treatment period. In the isradipine group n = 13), both systolic and diastolic blood pressure and number of blood pressure spikes decreased significantly (P less than .0001), whereas there was a significant increase of these variables in the placebo control group (n = 13). The results of this study indicate that, in these subjects, blood pressure control was achieved throughout the 24-h period by monotherapy with isradipine.
