The invention provides valsartan dispersible tablets and a preparation method thereof, which contain effective doses of valsartan and pharmaceutical adjuvants, which include disintegrants, diluents, binders, lubricants, glidants and surface Active agent, based on 100 parts of valsartan, the dosage of disintegrating agent is 2-50 parts, the dosage of diluent is 10-150 parts, the dosage of binder is 2-25 parts, and the dosage of lubricant is 0.5-20 parts. The dosage of the liquid agent is 0.2-10 parts, and the surfactant is 0.1-2.5 parts; the present invention also provides the preparation method of the valsartan dispersible tablet. Compared with other dosage forms, the valsartan dispersible tablet has a good dispersion state , Short disintegration time, rapid drug dissolution, convenient administration, low production cost, no need for special equipment, convenient and stable carrying and transportation, etc.

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...
