Losartan Side Effects

Losartan is often sold under the brand name of cozaar. This medication is taken orally and is a part of a group of drugs known as angiotensin receptor blockers. Angiotensin is normally found in the blood stream. It may attach to muscle cells and force them to contract. This chemical may also cause blood vessels to constrict which leads to high blood pressure. Losartan stops this from happening by blocking receptors for angiotensin. By doing this, cells in the muscle cannot absorb angiotensin and the individual’s blood pressure is lowered.

Losartan was first approved by the FSA in 1995. Since then, it has been marketed in 25, 50 and 100 milligram doses to individuals with hypertension. It can reduce the chances of a stroke and treats hypertension. It has also been shown to be effective for patients with type 2 diabetes.
