LosartanHigh blood pressure, or usually referred to as hypertension, may cause fatal consequence if it is not treated promptly and effectively. Hypertension is triggered when arterial blood vessels are constricted and thereby increasing the resistance of blood flows and increasing the pressure against vessel walls. This increasing pressure consequentially forces the heart to work harder to pump blood. At severe level, hypertension may cause heart damage, stroke and kidney failure. Because of its life-threatening characteristic, hypertension is often regarded as a silent killer. Without proper treatment, this disease can develop and become a dangerous threat to the life of its sufferers.

There are two factors that affect the development of hypertension: the amount of blood that is pumped in the vessels and the diameter of the vessels. The more blood the heart has to pump and the narrower the arterial vessels through which the blood is pumped, the higher the blood pressure. Hypertension can be an essential one, i.e. one whose causes are still unidentifiable, and a secondary one, i.e. one whose causes have been identified. The most frequent cause of secondary hypertension is kidney disease. Kidney plays an important role in regulating blood pressure.

The constriction of arteries and the increase of blood pressure that follows occur because kidney produces an enzyme called renin that converts blood protein into hormone angiotensin. This hormone increases blood volume and consequentially blood pressure by inducing adrenal glands to release aldosterone, which further promotes the reabsorption of water and sodium. When the kidney is diseased, the production of angiotensin becomes abnormal, thereby increasing the risk of high blood pressure. Because the primary cause of secondary hypertension is the production of the hormone angiotensin, it is believed that high blood pressure can be overcome if the production of this hormone is controlled. This is why some medications that are used to treat hypertension are administered to the patients to control the production of the hormone angiotensin.

Among medications that are used to block angiotensin is losartan. The brand name of this medication is Cozaar and it is currently the only available form of this medication in the market because its generic form is no more available since 2009. This medication is categorized as angiotensin II receptor antagonist, a medication that blocks angiotensin and thereby preventing the constriction of arterial blood vessels. Other medications that are included in this category are candesartan (brand names: Blopress, Atacand, Amias, and Ratacand), irbesartan (brand names: Aprovel, Karvea, and Avapro), valsartan (Angiotan or Diovan), telmisartan (Micardis), azilsartan (Edarbi), and olmesartan (Benicar). Cozaar is prescribed for adults and children 6 years of age or older who suffer hypertension to lower their high blood pressure. This drug is not used to cure hypertension; it only lowers the blood pressure and controls it. By lowering their high blood pressure, serious diseases, such as stroke, heart attack, kidney problem, and type 2 diabetes can be prevented.
