Zestril is an oral tablet consisting of an ACE (angiotensin converting enzyme) inhibitor called lisinopril. We carry the brand choice and generic alternative of Zestril in 5mg, 10mg, and 20mg!

Zestril is prescribed to help treat high blood pressure. A person who has narrow arteries and a heart that pumps more blood than normal will have high blood pressure. Blood pressure is the force of the blood against the walls of your blood vessels and when that force is high, it causes your heart to have to work harder which can cause damage. If high blood pressure goes untreated for too long, a person may risk developing heart problems (like heart attack or stroke) and kidney problems. Additionally, this medication may be used to treat congestive heart failure or to improve survival after a heart attack.

Zestril (lisinopril) is effective at treating high blood pressure (and other conditions) because lisinopril is able to relax blood vessels to allow easier blood flow, thus reducing blood pressure.

Follow only the directions given to you by your doctor. Do not take more or less of a dose than directed. For the full benefit of the medication, ensure you take it regularly and create a routine by taking it around the same time every day. Continue using this medication even if you feel well-high blood pressure often shows little to no symptoms; usually those with high blood pressure need to take medications for the rest of their lives.

Lisinopril lowers blood pressure; this helps lower the risk of cardiovascular complications such as heart attack and stroke. Other complications of hypertension include weakened and narrowed blood vessels in the kidneys (resulting in kidney damage or failure) and thickened, narrowed, or torn blood vessels in the eyes (resulting in vision loss), which can be prevented with proper hypertension treatment.

How does Lisinopril work?

Normally, blood vessels are wide, which is optimal for smooth blood flow; however in cases of hypertension, blood flow is limited. High blood pressure occurs when the blood vessels become swollen and inflamed, resulting in the blood vessels width becoming smaller, limiting the amount of blood able to flow through, and raising overall blood pressure levels. Lisinopril is effective at lowering blood pressure because of its capability to relax the blood vessels so they widen back to normal, allowing proper blood flow to be restored.
