Abstract

The invention provides valsartan dispersible tablets and a process for preparation. The tablets contain an effective quantity of valsartan and medicinal findings which further contains disintegration agent, deflocculating agent, cementing agent, lubricating agent, flow assisting agent, and surface active agent, wherein the dosage of the valsartan is 100 parts, disintegration agent 2-50 parts, deflocculating agent 10-150 parts, cementing agent 2-25 parts, lubricating agent 0.5-20 parts, flow assisting agent 0.2-10 parts and surface active agent 0.1-2.5 parts. The invention provides the preparation process as well. In comparison with other preparation, the valsartan dispersible tablets have the advantages of excellent dispersing state, short disintegration time, fast speed of dissolving outof the drug, convenient taking medicine, low cost, convenient carrying and transporting, steady property and needs no special equipment and the like.

Description

technical field [0001] The invention belongs to the technical field of medicines, in particular to a valsartan dispersible tablet and a preparation method thereof. Background technique [0002] Angiotensin II receptor antagonists are a new class of antihypertensive drugs that have been on the market since 1996. Because of their good tolerance and definite blood pressure advantages, they have been widely used in clinical practice at home and abroad. Among them, valsartan is the second oral effective, potent and specific angiotensin II receptor antagonist successfully developed. [0003] The active hormone of the renin-angiotensin-aldosterone system is angiotensin II, which can be converted from angiotensin I under the action of ACE. Angiotensin II can bind to special receptors on cell membranes of various tissues, and it has a wide range of physiological functions, especially directly or indirectly involved in the regulation of blood pressure. As a potent vasoconstrictor, a...
