Losartan potassium Usage And Synthesis

Description

As a angiotensin II receptor antagonist, Losartan Potassium is the potassium salt of losartan with antihypertensive activity, which is mainly used in the therapy of high blood pressure (hypertension) and diabetic nephropathy. It functions by relaxing blood vessels so that blood can flow more easily. It is also effective to help protect the kidneys from damage caused by diabetes and lower the risks of stroke in patients suffering from hypertension and myocardial enlargement. Besides, recent study has suggested that losartan is beneficial to reverse age related dysfunction in maintaining normal blood pressure and cellular energy usage on mitochondria and it can probably be used to treat left ventricular hypertrophy. It may also be used as an alternative agent for the treatment of systolic dysfunction, myocardial infarction, coronary artery disease, and heart failure.

Description

Losartan potassium is the first potent and selective non-peptide angiotensin II (AT II) AT1 receptor antagonist introduced to the market as a once-daily oral antihypertensive. It is efficacious and long lasting in controlling blood pressure in spontaneous hypertensive rats, in patients with essential hypertension in addition to those patients with renal impairment. Since losartan functions by competitive antagonism at the level of receptor, which represents the most direct way of selectively inhibiting the renin-angiotensin system (RAS) independent of the source of AT II, its use has been reported to be free of the coughing side effect exhibited by the ACE inhibitors. In contrast to calcium channel blockers, losartan does not appear to cause ankle edema, headache and tachycardia. It is also reported to be in clinical trials for the treatment of heart failure. Other reports indicate that losartan may have potential efficacy as an anxiolytic, an antiglaucoma agent, in addition to in providing protection against stroke and in preventing the myointimal proliferative response of the vascular wall after coronary angioplasty and surgery.
