Overview
Cozaar 50mg Tablet contains losartan potassium 50mg, an angiotensin II receptor blocker (ARB) used to treat high blood pressure (hypertension) and to reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy. It is also used to slow the progression of kidney disease in people with type 2 diabetes.
Losartan works by blocking the AT1 receptor that angiotensin II normally binds to, preventing this hormone from narrowing blood vessels and retaining sodium. This allows blood vessels to relax, lowering blood pressure and reducing strain on the heart and kidneys.
How it Works
Losartan and its active metabolite selectively and competitively block the AT1 angiotensin II receptor in blood vessels and the adrenal gland, preventing vasoconstriction and aldosterone release. Losartan also has a mild uricosuric effect, modestly lowering blood uric acid levels.
Directions for Use
Take Cozaar 50mg Tablet at about the same time each day, with or without food. Swallow the tablet whole with a glass of water. Continue taking it even if you feel well, as high blood pressure usually has no symptoms, and do not stop suddenly without consulting your doctor.
Dosage
The usual starting dose of Cozaar 50mg Tablet for most adults with hypertension is 50mg once daily, which your doctor may increase up to 100mg once daily depending on your blood pressure response, or reduce for patients with a history of liver problems or reduced fluid volume. Always take losartan exactly as prescribed by your doctor.
