摘要

Tablet computer includes: at least 59.5% spray drying mannitol; Less than or equal to the active component to 10%, at least 90% has a granularity lower than 100 mum in the weight of active component here; Microcrystalline cellulose 10-18%, at least 99% has a granularity lower than 250 mum in the weight of microcrystalline cellulose with an average particle size of 50 mum and here; Cross-linked carboxymethyl 14%; One lubricant 0.5-2% ; Wherein, unless specifically indicated, the weight of the total weight of percentage tablet computer indicates. And one process include: the component in addition to lubricant screening and mixing; The mixing of all components; The direct compression of final mixture. Tablet computer of the invention gives the disintegration times and good sense organ of lower part on tongue after decomposing, overcomes the problems, such as encapsulating and the insufficient mechanical resistance of traffic circulation.
