Abstract

The invention relates to a tablet composition of antidepressant flupentixol and melitracen and a preparation method of the tablet composition. The composition comprises flupentixol (the particle size distribution D90 is smaller than 150mu m), melitracen, a filling agent, a disintegrating agent, an adhesive and a lubricating agent. The tablet composition is prepared from full-powder in a direct tabletting manner; and the method comprises the following steps: mixing step by step; tabletting; and coating and the like. The manufacturing process is simple; pelletizing and drying are avoided; energy and time are saved; the stability of active components is protected; the disintegration property and the dissolution rate of the tablet are improved; and the prepared tablet composition of antidepressant flupentixol and melitracen is stable in quality, low in impurity content, safe and good in effectiveness.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a flupentixol melitracen pharmaceutical composition and a preparation method thereof. Background technique [0002] Flupentixol (flupentixol) is a thiaxanthene atypical antipsychotic drug, which acts by blocking dopamine receptors in the mesencephalic-limbic system and midbrain-cortical system. Its chemical name is: α-trifluoromethyl- 9-{3-[4-(2-Hydroxyethyl)-1-diethylenediamine]-propane}-thioxanthene, the structure is shown in formula Ⅰ: [0003] [0004] Melitracen (melitracen) is a tricyclic (heterocyclic) antidepressant drug that inhibits the reuptake of norepinephrine and serotonin and increases the concentration of these two transmitters in the synaptic cleft. Its chemical name is: 3-[10,10-dimethyl-9(10H)-anthracene]-N,N-dimethyl-1-propanamine, and its structure is shown in formula II: [0005] [0006] Because flupenthixol may produ...
