Investigators stopped a trial on a pair of high blood pressure drugs after finding they were highly effective, providing promise for people at risk for strokes and heart attacks. Researchers have not disclosed details of the trial but report the benefits of the two drugs were "significant." Current treatment relies on atenolol, a beta-blocker, and bendroflumethiazide, a thiazide diuretic. The new treatment relies on amlodipine, a calcium channel blocker, and perindopril, an ACE inhibitor.
