When the heart beats, it pumps blood through your arteries to the rest of the body. At times, your blood will push harder against the artery walls, which causes your blood pressure to rise. For example, waking up in the morning, exercising, or feeling stressed out can cause your blood pressure to increase for a short amount of time, which is normal.

However, if your blood pressure is high in a constant manner, this is known as hypertension. According to the U.S. National Library for Medicine, about 76.4 million Americans have high blood pressure. This health condition may affect individuals across all ages, may express itself as a chronic or acute condition, and be caused by a wide variety of factors, including kidney impairment, heart disease, diabetes, obesity.



Hypertension can lead to severe complications, even to death, therefore, it should be monitored and treated adequately as soon as it has been detected in patients. Lifestyle modifications, stress management and proper diet play an important part in the treatment, however, acute cases and those refractory to non-invasive therapies, can benefit from drug administration either alone or in combination.

Thus Lisinopril acts by preventing the action of ACE. L
