Losartan 100mg: Uses, Side Effects, And Dosage Information

Losartan is a medication that has been widely used to treat high blood pressure and protect the kidneys from damage due to diabetes. It belongs to a class of medications known as angiotensin II receptor blockers (ARBs), which work by relaxing blood vessels and reducing blood pressure. In this article, we will delve into the uses, side effects, and dosage information of Losartan 100mg.

What is Losartan Used For?

Losartan is primarily used to treat high blood pressure (hypertension) in adults and children over six years old. It is also used to protect the kidneys from damage in people with type 2 diabetes and high blood pressure. Additionally, Losartan may be prescribed to reduce the risk of stroke in people with high blood pressure and an enlarged heart.

How Does Losartan Work?

Losartan works by blocking the action of angiotensin II, a natural chemical that constricts blood vessels and increases blood pressure.
