Abstract

The invention belongs to the field of pharmaceutical preparations, and relates to a glucocorticoid drug tablet and a preparation method thereof. The raw material medicine of the tablet is methylprednisolone having a particle size of D90 30-40 [mu]m, and the preparation method comprises the following steps: the raw material medicine is pulverized by air flow, and then uniformly mixed with a filler,a disintegrating agent and a lubricant, and then a mixture compressed to obtain a finished product. The glucocorticoid drug tablet prepared by the method has the advantages of high dissolution rate and high stability, and the preparation process improves preparation efficiency, reduces equipment energy consumption, and is suitable for industrial large-scale production.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a glucocorticoid pharmaceutical tablet and a preparation method thereof. Background technique [0002] Methylprednisolone is a glucocorticoid successfully developed by Upjohn Company of the United States in the 1950s. It is a medium-effect glucocorticoid drug. This product can be used for maintenance treatment of some critically ill patients after emergency treatment. Anti-allergic, anti-shock and other pharmacological effects. The anti-inflammatory effect of the drug is strong, equivalent to 5 times that of hydrocortisone and 1.4 times that of prednisone. Among glucocorticoids, methylprednisolone has the strongest affinity with glucocorticoid receptors, while mineralocorticoid-like effects (such as water and sodium retention) are weak, and the inhibitory effect on the hypothalamus-pituitary-adrenal axis is weak, so the drug is discontinued After that, the...
