Abstract
There is sound statistical evidence that Visken in thirty randomly selected cases was on the average more effective than Aldomet. The results also show that Visken is an excellent drug to lower both systolic and diastolic pressures without a marked effect on posture. Higher systolic and diastolic pressures are lowered more effectively than the lower pressures. The fact also emerges that there is no sound statistical evidence that Visken is more effective for either of the sexes or that efficacy of therapy shows predeliction for a specific age group. Visken was well tolerated and showed no significant side-effects.
