P. Larochelle et al., EFFECTS AND TOLERABILITY AT IRBESARTAN VERSUS ENALAPRIL IN PATIENTS WITH SEVERE HYPERTENSION, The American journal of cardiology, 80(12), 1997, pp. 1613
In this double-blind, randomized study, an antihypertensive regimen ba
sed on irbesartan, an angiotensin II receptor antagonist, reduced syst
olic and diastolic blood pressure by 40/30 mm Hg at week 12 in patient
s with severe hypertension; this reduction was at least equivalent to
that of a regimen using enalapril up to 40 mg. The irbesartan-based re
gimen had a better tolerability profile with fewer adverse events (55%
vs 64%) and significantly less cough (2.5% vs 13.1%, p = 0.007).
