Antihypertensive drugs: diuretics and betablockers are the best assessed.
(1) In trials involving hypertensive non diabetic patients under 65, some diuretics and betablockers have prevented strokes, without conferring protection from coronary events or death.  In one trial captopril had an effect comparable to that of diuretics or betablockers in terms of overall cardiovascular prevention, but was a little less effective in preventing strokes.  (2) In trials involving hypertensive subjects over 65, some diuretics and betablockers have reduced the risk of stroke, coronary events, heart failure, and death.  In one trial a diuretic was superior to a betablocker in terms of preventive efficacy and adverse effects.  Nitrendipine, in combination with other antihypertensive drugs, prevented strokes in one trial.  (3) In a trial involving hypertensive diabetic patients, captopril and atenolol reduced the risk of stroke, heart failure and worsening of retinal disease, without preventing coronary events or death.  In two trials coronary events were more frequent on dihydropyridine than on an angiotensin-coverting-enzyme (ACE) inhibitor.  (4) In one trial a diuretic reduced the risk of relapse after stroke, even in patients without severe hypertension.
