Prospective studies have emphasized the key role for diuretics in the
treatment of high blood pressure. Short-acting loop diuretics have not
achieved the same acceptance as the thiazides in treatment of hyperte
nsion. Newer long-acting compounds, however, such as torasemide, have
now been found to be as efficacious as the thiazides, particularly as
they can be given once daily and have a low side-effect profile. Adver
se laboratory side-effects are rare in hypertensive patients treated w
ith torasemide; carbohydrate intolerance, dyslipidaemia, or hypokalaem
ia have seldom been observed during its longterm administration. For t
hese reasons, torasemide is therapeutically attractive due to its anti
hypertensive efficacy with once-daily administration, low incidence of
adverse side-effects, and sustained improvement of the cardiovascular
risk profile.
