Examples
Embodiment 1
[0046] Dissolve vortioxetine hydrobromide (50 mg), D-mannitol (50 mg) and povidone K30 (50 mg) in methanol (800 microliters), heat to 60°C and stir to dissolve. The above solution was rapidly cooled to -10°C, a white solid was precipitated, filtered, and dried to obtain a composition of amorphous vortioxetine hydrobromide, D-mannitol and povidone K30, the X-ray of the composition Powder diffraction pattern as figure 1 As shown, there is no characteristic peak of the vortioxetine hydrobromide crystal form in the X-ray powder diffraction pattern after deducting the background peak of the pharmaceutical excipient.
Embodiment 2
[0048] Vortioxetine (50 mg), polyacrylic acid resin Eudragit L100 (50 mg) and polyethylene glycol 4000 (200 mg) were dissolved in ethanol (600 μl) and water (600 μl) at -40 °C Stir down to mix well. The above solution is slowly concentrated to dryness in a rotary evaporator to obtain a white solid, which is a composition of amorphous vortioxetine, polyacrylic acid resin Eudragit L100 and polyethylene glycol 4000, and the X-ray powder diffraction pattern of the composition Among them, there were no characteristic peaks of vortioxetine crystal form after deducting the background peaks of pharmaceutical excipients.
Embodiment 3
[0050] Add vortioxetine hydrochloride (2 g), lactose (2 g) and polyethylene glycol 8000 (10 g) into water (300 ml), heat to 60°C and stir to dissolve. The above solution was dried with JISL micro-spray dryer LSD-48, and the inlet temperature was maintained at 60°C and the outlet temperature was 50°C. The composition of ethylene glycol 8000, in the X-ray powder diffraction diagram of the composition, there is no characteristic peak of vortioxetine hydrochloride crystal form after deducting the background peak of pharmaceutical excipients.
