In every house, we come across individuals suffering from one or the other health issue especially blood pressure. It is observed that high blood pressure is a very common ailment.

As per the American College of Cardiology and American Heart Association nearly half of adults in the US (47%, or 116 million) have hypertension.

Only about 1 in 4 adults (24%) with hypertension have their condition under control. As we compare between men and women, a percentage of men (50%) have a higher blood pressure than women (44%).

So what exactly is blood pressure? Blood pressure is the pressure used by the blood against the walls of your arteries to help circulate blood across various body parts.

The normal blood pressure range is less than 120 on top and less than 80 on the bottom. High blood pressure occurs when your blood applies pressure that is higher than this range. It is also known as hypertension.

Oftentimes, high blood pressure is also termed a “silent killer” because you may not experience any symptoms indicating a problem with blood pressure. A few people may experience headaches, nosebleeds, or shortness of breath.

Food, medicine, lifestyle, health conditions, age, and genetics cause high blood pressure. High blood pressure can damage blood vessels of the brain, heart, and kidneys resulting in a stroke, heart failure, or kidney disease.

High blood pressure should not be taken lightly. It should be treated as soon as possible to avoid unnecessary complications. Lisinopril and Losartan are medicines that are mainly used to treat high blood pressure.

Do You Know About Lisinopril And Losartan?

Lisinopril is an angiotensin-converting enzyme(ACE) inhibitor. It treats high blood pressure, and heart failure improves survival in people who had a heart attack, and also prevents future heart attacks.

It is not available over the counter as it is a prescription-based drug though you can purchase Lisinopril over the counter from a certified online pharmacy it is recommended to get a doctor's prescription first.

Lisinopril, which is an ACE inhibitor, means it blocks the action of ACE enzymes in the renin-angiotensin system(RAS). Lisinopril prevents angiotensin-I from being converted to angiotensin-II.

By blocking the production of angiotensin-II, Lisinopril keeps blood vessels open and relaxed which lowers Blood pressure (Lancaster, S.G. and Todd, P.A., 1988).

Losartan is known as an Angiotensin-II receptor blocker. Losartan is used to treat high blood pressure, stroke risk, and kidney problems associated with diabetes.

with a proper doctor's prescription, you can also purchase Losartan over the counter from a certified online pharmacy. Losartan blocks the action of Angiotensin-II.

Angiotensin-II is a substance that narrows blood vessels and causes high blood pressure and it becomes hard to pump the blood.

Thus Losartan helps to relax your veins and arteries to lower the blood pressure and make it easier for your heart to pump blood (Simpson, K.L. and McClellan, K.J., 2000).
