Embodiment 1
[0050] Any solid form of vortioxetine hydrobromide can be used in the preparation of the pharmaceutical composition of the present invention.
[0051] The calculation method of the load rate of vortioxetine hydrobromide in the pharmaceutical composition is as follows:
[0052] Loading rate=(feeding weight of vortioxetine hydrobromide-the loss weight of vortioxetine hydrobromide in filtrate) / the gross weight of pharmaceutical composition
[0053] Vortioxetine hydrobromide (50 mg) and povidone K30 (30 mg) were added to methanol (900 microliters), heated to 60 ° C and stirred to dissolve, then added colloidal silicon dioxide Aerosil 200 ( 30 mg) and microcrystalline cellulose (20 mg). The above mixture was rapidly cooled to -10°C, a white solid was precipitated, filtered, and dried to obtain a composition of amorphous vortioxetine hydrobromide, povidone K30, microcrystalline cellulose and colloidal silicon dioxide Aerosil 200 121 mg, the loading rate of the active ingredient is...
Embodiment 2
[0055] Vortioxetine (50 mg) and hydroxypropyl methylcellulose HPMC E3 (30 mg) were added to methanol (800 microliters) and dichloromethane (800 microliters), stirred and dissolved at 40 ° C, and then added Colloidal Silicon Dioxide Aerosil 200 (30 mg) and Mannitol (50 mg). The above mixture was slowly concentrated to dryness in a rotary evaporator, and further dried in vacuum to obtain a white solid, namely a combination of amorphous vortioxetine, hydroxypropylmethylcellulose HPMC E3, mannitol and colloidal silicon dioxide Aerosil 200 160 mg, the loading rate of the active ingredient is 31.2%. The X-ray powder diffraction pattern of this composition is as follows figure 2 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 3
[0057] Vortioxetine hydrobromide (2 g) and polyethylene glycol 8000 (1.2 g) were added to methanol (50 ml), heated to 60°C and stirred to dissolve, then magnesium aluminum silicate Neusilin UFL2 (0.6 grams) and lactose (2 grams). The above mixture was slowly concentrated to dryness in a rotary evaporator, and further vacuum-dried to obtain a white solid, which was further vacuum-dried to obtain amorphous vortioxetine hydrobromide, polyethylene glycol 8000, lactose and magnesium aluminum silicate Neusilin The composition of UFL2 is 5.8 g, and the loading rate of active ingredient is 34.4%. In the X-ray powder diffraction pattern of the composition, there is no characteristic peak of the crystal form of vortioxetine hydrobromide after deducting the background peak of the pharmaceutical excipient.
