Benefits of technology

"The patent is about a method for making quickly disintegrating tablets that can be produced without special manufacturing techniques. The method involves combining an active ingredient, a saccharide or sugar alcohol, a disintegrating agent, and a cellulose compound. The resulting tablet has good hardness, disintegrates quickly, and is easy to manufacture. The patent also describes specific ingredients that can be used in the tablet formulation. The technical effect of this invention is to provide a simple and effective method for producing quickly disintegrating tablets."

Problems solved by technology

In addition, pulverization is undesirable not only because it strengthens the friction at the surface of the mortar wall but also from the viewpoint of handling because it reduces fluidity during the production of the tablet preparation (Summary of lectures at the 14th Symposium on Particulate Preparations and Designs, p.

Abstract

Quickly disintegrating solid preparations which contain: a) an active ingredient; b) D-mannitol having an average particle size of 30 μm to 300 μm; c) a disintegrating agent; and d) celluloses.

Description

TECHNICAL FIELD [0001] The present invention relates to solid preparations that disintegrate quickly in the presence of saliva or a small amount of water in the oral cavity, particularly those useful as intraorally disintegrating solid preparations. BACKGROUND ART [0002] For aged people and children who are difficult to swallow drugs, solid preparations that disintegrate or dissolve quickly in the oral cavity have long been developed. For example, an intraorally disintegrating tablet preparation is described in the International Publication No. WO93 / 12769, which is obtained by suspending a drug, lactose, and mannitol in aqueous agar solution, filling the resulting suspension in a molding pocket or the like, and drying the molding under reduced pressure. This molding shows quick disintegration but is more fragile than usual tablets so that it is readily cracked, chipped, etc. and a long time is required for its production; thus the process for production is poor in productivity. In J...
