Brief Overview of Zestril

Zestril, also known as Lisinopril, is a prescription medication used to treat high blood pressure (hypertension). It belongs to a class of drugs called ACE inhibitors, which work by relaxing blood vessels to improve blood flow. Zestril is typically taken once a day and can be prescribed alone or in combination with other medications.

How Zestril Works

Zestril works by inhibiting an enzyme in the body that is involved in the production of a substance that narrows blood vessels. By blocking this enzyme, Zestril helps to widen the blood vessels, allowing blood to flow more easily and reducing blood pressure.

Common Side Effects

Common side effects of Zestril may include dizziness, headache, cough, and fatigue. It is important to talk to your healthcare provider if you experience any side effects while taking Zestril.

Precautions and Interactions

Before taking Zestril, it is important to inform your healthcare provider about any other medications you are taking, as well as any medical conditions you have. Zestril may interact with certain medications, such as diuretics or potassium supplements, so it is important to discuss your full medical history with your doctor.

Cost and Availability

The cost of Zestril may vary depending on your insurance coverage and the pharmacy you use. On average, a 30-day supply of Zestril can cost around $50 to $100 without insurance. It is available in both brand-name and generic forms.

Expert Opinions

According to a study published in the American Journal of Medicine, Zestril has been shown to significantly reduce blood pressure in patients with hypertension. The study found that Zestril was effective in lowering blood pressure levels, with minimal side effects reported.


In conclusion, Zestril is an effective medication for the treatment of high blood pressure. It is important to follow your healthcare provider’s instructions when taking Zestril and to report any side effects or concerns. Zestril can help to improve blood pressure levels and reduce the risk of complications associated with hypertension.
