Losartan Potassium Description

Losartan competes with the binding of angiotensin II to AT1 receptors. The concentration that inhibits 50% of the binding of angiotensin II (IC50) is 20 nM. Losartan (40 μM) affects ISC but prevents the effect of ANGII on ISC. Losartan significantly reduces Ang II-mediated cell proliferation in endometrial cancer cells. The combination of losartan and anti-miR-155 has a significantly greater antiproliferative effect compared to each drug alone.

Losartan potassium is a prescription drug used to treat hypertension (high blood pressure).

How Losartan Potassium Works?

Losartan Potassium relaxes blood vessels by blocking angiotensin II. Angiotensin II is a vasoconstrictor that narrows blood vessels, causing blood pressure to rise.
Losartan Potassium reduces the secretion of aldosterone. Aldosterone is a hormone that causes the kidneys to retain sodium and water, causing an increase in blood volume and blood pressure. Angiotensin II stimulates the release of aldosterone. By blocking angiotensin II, Losartan Potassium reduces aldosterone secretion, which helps further lower blood pressure.

Losartan Potassium Applications

Losartan is a medication mainly used to treat high blood pressure. It is also used for diabetic kidney disease, heart failure, and left ventricular enlargement. It may be used alone or in addition to other blood pressure medication. Up to six weeks may be required for the full effects to occur.
