What are Losartan tablets?

Losartan is an angiotensin II receptor blocker (ARB) that is primarily used in the treatment of high blood pressure (hypertension), diabetic nephropathy, and heart failure.

Losartan tablets are typically prescribed after suffering a heart attack as they can also help to prevent further complications such as strokes, heart attacks, and kidney problems.

You need a prescription to buy Losartan tablets. 

What is Losartan used to treat?

Angiotensin Receptor Blockers (ARBs) formally known as angiotensin II receptor antagonists are most used to treat high blood pressure (HBP) and any conditions related to the effects of HBP. Losartan can also help to treat and prevent other serious illnesses, including heart failure, kidney disease, strokes and heart attacks when used regularly.

Although Losartan is not the preferred first-line treatment for HBP, it is the first-line treatment option in individuals who cannot tolerate the adverse effects of ACE inhibitors, such as a dry cough.

Losartan also helps to reduce inflammation and as a result, can be used to treat heart failure and fatty liver disease. Losartan helps to improve the quality of life and life expectancy in people with heart failure.

Why is Losartan prescribed to treat high blood pressure?

Losartan has been used to treat several high blood pressure-related conditions since 1995 and is featured on the World Health Organisation's List of Essential Medicine.

How does Losartan treat high blood pressure?

As an Angiotensin Receptor Blockers (ARBs), Losartan works by reducing the action of a hormone that is natural to the human body called Angiotensin II (Ang II), which plays a significant role in hypertension.

Angiotensin II (Ang II) raises blood pressure in several ways, by causing blood vessels to restrict which makes it harder for the heart to pump blood around the body. Angiotensin II (Ang II) increases salt and water retention in the body, which also increases blood pressure.

Angiotensin II (Ang II) is mediated by the AT1 Receptors that are found in the heart. Losartan blocks the activation of the AT1 receptors, which directly causes the blood vessels to widen. This lowers blood pressure.
