Abstract
AIM:
To study efficacy and safety of a new dose and dosage form of proxodolol--a betaadrenoblocker with alpha1-adrenoblocking activity--in patients with moderate arterial hypertension (AH).
MATERIAL AND METHODS:
A total of 60 patients with verified diagnosis of essential AH of the second degree were randomized into two groups: group 1 (n=40) received proxodolol, group 2 (n=20) was given carvedilol. The trial lasted for 89 days.
RESULTS:
The trial demonstrates that proxodolol is highly effective and safe in the treatment of AH.
CONCLUSION:
Proxodolol is effective and safe in hypertension, in a dose 120 mg its activity is the same as carvedilol in a dose 25 mg.

• What is already known on this topic
• Angiotensin receptor blockers are important in the treatment of cardiovascular conditions
• Previous studies have shown an increased risk of myocardial infarction with these drugs and have raised concern among physicians and patients
• What this study adds
• There is firm evidence to refute the hypothesis of angiotensin receptor blockers increasing the risk of myocardial infarction (ruling out even a
0.3% absolute increase)
• Compared with controls (active treatment or placebo), angiotensin receptor blockers reduce the risk of stroke, heart failure, and new onset diabetes.
• Despite lower blood pressure with angiotensin receptor blockers when compared with placebo, there also was no detectable beneficial effect for the outcome of myocardial infarction or cardiovascular mortality

International trial in 22,576 patients with CAD and hypertension
Randomized to multi-drug treatment strategies
• verapamil SR + trandolapril + HCTZ
• atenolol + HCTZ + trandolapril
• Trandolapril recommended for all patients with diabetes
Primary Outcome: First occurrence of all-cause mortality, nonfatal MI or nonfatal stroke
Secondary Outcomes: All-cause mortality, nonfatal MI, nonfatal stroke, total MI and total stroke
Main finding: risk for CV adverse outcomes was equivalent comparing the strategies
