Problems solved by technology

[0015] The present invention disperses isosorbide mononitrate in a non-physiologically active water-soluble carrier to prepare a drug-carrier solid dispersion, and isosorbide mononitrate is dispersed in the carrier in an ultrafine crystal state to form a uniform deep eutectic physical The mixture microcrystalline dispersion system, and then mixed with disintegrants, fillers, glidants, lubricants, and flavoring agents, and then directly compressed into tablets. Solved the problems of freeze-drying, vacuum-drying and spray-drying preparation of orally disintegrating tablets, complex production process equipment, high production conditions, poor tablet hardness and integrity, special packaging, inconvenient storage, transportation and taking, and also overcome Problems of disintegration and incomplete dispersion of orally disintegrating tablets prepared by direct compression method after preparing solid dispersion by conventional melting method

Abstract

The invention relates to isosorbide mononitrate mouth slaking tablet and the formula and preparing process. The process employs rotary oscillating granulator to produce said slaking agent through direct sheeting method after heat extrusion by melting and gradient cooling. When compared with mouth slaking agent produced with normal melting method, the mouth slaking agent in this invention is characterized by faster slaking speed, higher dissolution rate, intact tablet outlook, stronger rigidity and good taste. If compared with current freeze drying, vacuum drying, spray drying technique, the invention is characterized in that it needs no special production device and condition, no special package, the production process is simple, quality is stable and suitable for industrial production. It provides new products for patients that is dysphagia and bedridden, for old people and children, especially for patients that suffering angina pectoris and coronary heart disease.

Description

technical field [0001] The invention relates to an orally disintegrating tablet of isosorbide mononitrate and a prescription and a process for preparing an orally disintegrating tablet of isosorbide mononitrate by adopting gradient cooling through molten hot extrusion and granulating and direct tableting by a rotary swinging granulator. Background technique [0002] Isosorbide mononitrate is the main biologically active metabolite of isosorbide dinitrate. Like other nitrate vasodilators, the main pharmacological effect is to relax vascular smooth muscle. Compared with isosorbide dinitrate, isosorbide mononitrate not only has the characteristics of rapid and complete absorption, no first-pass effect, high bioavailability, long duration of action, high clinical efficacy, etc., but also has outstanding advantages such as small individual differences and low toxicity , can prevent and reduce drug resistance in patients, is currently one of the best drugs for preventing and treat...
