Low the generation modulo null water of the solid solution which designates the dissolved due to brief heating and rapidity drying active material

摘要

A method of producing a solid solution in the form of granules or a powder form of the low solubility agent, take a molecular dispersed form in the auxiliary matrix, low soluble substance is a solution containing the matrix auxiliaries and low solubility active ingredient A method of producing by spraying, a step of dissolving a poorly soluble materials and steps, is heated to a temperature above its boiling point at atmospheric pressure an aqueous suspension of the low solubility agent in the presence of the matrix auxiliaries is 90 ℃ ~350 ℃ temperature of the spray solution before comprises the step of solidified by spray drying a solution containing the matrix auxiliaries and low soluble substance is then introduced to the spray device, the above method.
