In the meantime, it is worthy to present the option to
start low doses of BP agents for individuals who do not
respond to the prescription of lifestyle modification.

Tratamento medicamentoso
Diuretics are still essential drugs for hypertension
management, but diuretics with higher potency and
duration of action, such as chlorthalidone, should be
preferred.

Efeitos renais em trials recentes
ROADMAP (N Engl J Med 2011; 364:907): the reduction in
glomerular filtration rate was higher in patients
treated with olmesartan instead of placebo (P<0.001).
ACTIVE (N Engl J Med 2011; 364:928): the incidence of renal
dysfunction leading to discontinuation of the drug
almost doubled in patients treated with irbesartan
(0.95%) than placebo (0.53%), P = 0.02.
TRANSCEND (Ann Intern Med 2009; 151:1-10): the
decreasing in glomerular filtration rate was greater
with telmisartan than with placebo (P < 0.001)
