valsartan

Valsartan is an angiotensin II receptor antagonist in the class of antihypertensive drugs, which can block the type I (AT1) receptor of angiotensin II, increase the plasma level of angiotensin II, stimulate the unblocked AT2 receptor, and at the same time counteract the effect of AT1 receptor, so as to achieve the effect of dilating blood vessels and reducing blood pressure. In the United States, valsartan is used to treat high blood pressure, congestive heart failure, and post-myocardial infarction. Diovan Valsartan, developed and produced by Ciba-Jiagi, Switzerland, obtained the relevant patent rights in the United States and Europe in 1995 and 1996 respectively, and was listed in Germany for the first time in July 1996, and has since been listed in Europe, the United States and Japan. Ciba Giaggi and Sandoz merged to form Novartis in 1996. Valsartan has the characteristics of lasting and stable effect of lowering blood pressure and little side effects
