Abstract

The invention discloses an Eyer calciferol soft capsule preparation method which includes the steps: preparing capsule shells; preparing contents; pressing soft capsules. A preparation method of the contents includes the steps: taking Eyer calciferol, adding absolute ethyl alcohol, and stirring and dissolving mixture by the aid of a glass bar; adding median chain triglyceride oil and vitamin E, and electrically stirring mixture for 1-2 hours; transferring solution to a rotary evaporator, rotatably evaporating the solution at the temperature of 40-60 DEG C and at the pressure of 0.08-0.1Mpa, and enabling residue content to be lower than 0.5% according to detection; transferring solution to a stirring tank, and adding and stirring the median chain triglyceride oil; adjusting filled volume and pressing pills. A lot of experimental researches are implemented, temperature, pressure and time of rotary evaporation are controlled, residue of the absolute ethyl alcohol is controlled, and the absolute ethyl alcohol is removed. The Eyer calciferol soft capsule without ethyl alcohol can have effect on more patients, and particularly, alcoholic allergy people can be more effectively treated.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a preparation method of Alcalcitol soft capsules. Background technique [0002] Alcalcidol Soft Capsules is a drug for the treatment of osteoporosis. The Ministry of Health and Welfare of Japan approved the production and marketing of Chugai Pharmaceutical Co., Ltd. in January 2011. The active substance Alcalcidol is another new product after alfacalcidol. Active vitamin D3 derivatives for the treatment of osteoporosis. A 3-year phase III clinical data involving 1,054 patients with osteoporosis showed that alcalcidol is more effective than alfacalcidol, and its safety is similar to that of alfacalcidol. application prospects. [0003] Chinese name: Alcalciferol [0004] Structural formula: [0005] [0006] Molecular formula: C 30 h 50 o 5 [0007] Molecular weight: 490.72 [0008] The active ingredient of this product, Alcalcitol, is easily soluble in N, N-...
