Effects of antihypertensive drugs on SBP variability are dose-dependent and persist when used in combinations .
Use of a high dose of a calcium channel blocker alone or in combination with other agents is therefore likely to be particularly effective in prevention of stroke
BACKGROUND AND PURPOSE Recent studies have shown that visit-to-visit blood pressure variability is a powerful risk factor for stroke , is reduced by calcium channel blockers and diuretics , and increased by β-blockers .
However , it is unknown whether these effects are dose-dependent and persist in combination with other drugs .
Perindopril as monotherapy in hypertension: A multicenter comparison of two dosing regimens
Perindopril erbumine , a new long‐acting , non‐sulfhydryl‐containing angiotensin converting enzyme inhibitor , was evaluated in 289 patients with hypertension in a 16‐week , double‐blind , placebo‐controlled dose‐ranging study . After 4 weeks of single‐blind placebo treatment , patients with supine diastolic arterial pressures from 95 to 114 mm Hg were r and omized to receive placebo , 4 mg perindopril once daily , or 2 mg perindopril twice daily . The daily dose of perindopril was increased by 4 mg every 4 weeks to a maximum of 16 mg per day . Mean decreases in systolic and diastolic arterial pressure were greater with perindopril than with placebo ( p < 0.05 ) . The dose‐response curve flattened after 8 mg per day , and there was no difference in arterial pressure reduction or in the percentage of responders between once‐ and twice‐daily administration of perindopril . Adverse reactions with perindopril were generally mild and , with the exception of cough , were similar with placebo . The findings of this study indicate that perindopril is effective , well tolerated , and suitable for once‐daily administration for the treatment of hypertension
