What Tanatril is and what it is
used for

Tanatril is used to treat high blood pressure
(hypertension). Tanatril is one of a group of
medicines called ACE (angiotensin-converting
enzyme) inhibitors.

diuretics (‘water tablets’), dialysis, a low salt diet
or because you have had strong and prolonged
vomiting or diarrhoea. You are more likely

If you have high blood pressure, Tanatril works
by widening blood vessels, so that blood passes
through them more easily. Since blood pressure
depends on the diameter of blood vessels, your
blood pressure will be lowered by Tanatril. Also,
it will be easier for your heart to pump blood
through the vessels around the body.
