Identification

Generic Name
Tasosartan
DrugBank Accession Number
DB01349
Background

Tasosartan is a long-acting angiotensin II (AngII) receptor blocker. Its long duration of action has been attributed to its active metabolite enoltasosartan. It is used to treat patients with essential hypertension.

Pharmacodynamics

By blocking the angiotensin II (AT1) receptor, the drug ultimately causes vasodilation, reduced secretion of vasopressin (ADH), reduced production and secretion of aldosterone, amongst other actions leading to the combined effect of a reduction of blood pressure.

Mechanism of action

Tasosartan is a selective, potent, orally active and long-acting nonpeptide Angiotensin II type 1 (AT1) receptor antagonist. Tasosartan blocks the renin-angiotensin-aldosterone system (RAAS) at the level of the AT1 receptor that mediates most, if not all, of the important actions of Ang II. Tasosartan binds reversibly to the AT1 receptors in vascular smooth muscle and the adrenal gland. As angiotensin II is a vasoconstrictor, which also stimulates the synthesis and release of aldosterone, blockage of its effects results in decreases in systemic vascular resistance. AT1 receptor antagonists avoid the nonspecificity of the Ang I converting enzyme (ACE) inhibitors.
