Zestril is part of a class of drugs called ACE inhibitors. ACE stands for angiotensin-converting enzyme. Zestril helps to block this enzyme, which is normally part of a reaction in the body that causes blood vessels to narrow (constrict). By blocking this enzyme, Zestril causes blood vessels to relax, which can lower blood pressure.
By helping blood vessels relax, Zestril also increases the efficiency of the heart. This means that the heart does not have to work as hard and more blood can be pumped out to the rest of the body. Both of these are helpful for a person with congestive heart failure.
Zestril Uses in Children
Zestril has been approved for the treatment of high blood pressure in children 6 years of age and older.
Off-Label Zestril Uses
On occasion, your healthcare provider may recommend Zestril for treating something other than the conditions listed in this article. This is called an "off-label" use. One off-label use of Zestril is treatment of kidney problems in people with scleroderma (which is hardening and thickening of the skin).
