potassium losartan

Fifth Affiliated Hospital, Sun Yat-Sen University · FDA-approved active Small molecule ✓ Verified Jun 2026

potassium losartan is a Angiotensin II receptor blocker (ARB) Small molecule drug developed by Fifth Affiliated Hospital, Sun Yat-Sen University. It is currently FDA-approved for Hypertension, Heart failure with reduced ejection fraction, Diabetic nephropathy in patients with type 2 diabetes. Also known as: Kesiya, Losartan, Placebo.

Losartan blocks angiotensin II type 1 receptors, preventing vasoconstriction and aldosterone release to lower blood pressure.

Losartan is used to treat conditions such as hypertension, diabetes mellitus, and sleep apnea, as indicated by ClinicalTrials.gov. It is classified as an angiotensin receptor blocker (ARB), which is a type of non-ACEI/ARB intervention, according to ClinicalTrials.gov and ChEMBL.

Mechanism of action

Losartan is an angiotensin II receptor blocker (ARB) that selectively antagonizes AT1 receptors on vascular smooth muscle and adrenal tissue. By blocking angiotensin II signaling, it causes vasodilation and reduces sodium and water retention, thereby decreasing blood pressure and reducing cardiac workload. The potassium salt formulation provides the active losartan component while delivering potassium as the counterion.
