Method for producing a crystalline tableting additive, additive thus obtained and use thereof
Abstract
In the present invention, particles the thing; for which at least one copy prepares an amorphous additive agent and the additive agent for the formation of a spray dry tablet of the particulate morphology whose at least one copy consists of crystalline additive agents, and this particle, It is related with the production method of the additive agent for tablet-izing including crystallizing an amorphous additive agent by being exposed to the temperature of 30*100 °C with a short time and 60*25% of relative humidity under churning. Especially the relation between relative humidity and temperature is defined by formula: relative humidity % = 218 * 47 * Ln (T (°C)) [the inside of a formula and T (°C) are temperature to which particles are exposed].
