Example Embodiment

[0033] The preparation method of calcium preparation provided by the invention comprises the steps:

[0034] In the first step, the calcium salt is mixed with the diluent to obtain mixture 1;

[0035] In the second step, the mixture 1 is wet granulated with a binder solution containing vitamin K to obtain primary granules;

[0036] The third step, spraying the vitamin D ethanol solution on the primary particles to obtain secondary particles; and

[0037] In the fourth step, the secondary particles are mixed with flavoring agents, lubricants, and / or fillers to obtain the calcium preparation provided by the present invention.

[0038] The diluent described in the first step above is selected from two or more of the following: glucose, starch, mannitol, sucrose, xylitol, lactose, dextrin, and microcrystalline cellulose.

[0039] The binder described in the above-mentioned second step is selected from one or more of the following: starch, glucose, povidone, and hydroxypropyl met...

[0063] Preparation of Vitamin DK Calcium Formulation 1 (1000 Tablets Quantity)

[0064] prescription:

[0065] raw material

[0066] Process steps:

[0067] Pass the calcium carbonate, vitamin D, and vitamin K in the recipe amounts through a 100-mesh sieve, and pass the recipe amounts of povidone, glucose, and magnesium stearate through an 80-mesh sieve; dissolve the povidone in water at about 50°C, and stir for 30 minutes. 2 minutes, to form a uniform binder solution for later use; put calcium carbonate, glucose, vitamin D, and vitamin K in a V-type mixer, and mix evenly; put the mixed materials in a wet granulation pot to prepare 20 mesh sieve to granulate; put the granulated granules into a fluidized bed, and dry at 50°C; mix the prepared granules with the prescribed amount of magnesium stearate evenly, and press into tablets.

Abstract

The invention discloses a calcium preparation, a preparing method thereof and applications thereof. The calcium preparation comprises a calcium salt, vitamin D, vitamin K, mannitol and glucose. The weight ratio of the vitamin D to the calcium salt is 2*10<-6>-22*10<-6>:1. The weight ratio of the vitamin D to the vitamin K is 1:2-50. The weight ratio of the mannitol to the glucose is 1:5-5:1.

Description

technical field [0001] The invention relates to the field of calcium supplementation, in particular to a new calcium preparation and its preparation method and application. Background technique [0002] As people age, osteoporosis has become an important public health problem. According to expert predictions, there are about 84 million osteoporosis patients in my country, accounting for 6.6% of the total population, and the number will double by 2050, which is reasonable. Calcium supplementation can effectively solve this problem, reduce bone loss and reduce the risk of fractures. [0003] If calcium is supplemented alone, the absorption and utilization rate of calcium is extremely low, and the danger of kidney stones will increase. Usually, vitamin D is added to calcium preparations. However, long-term use of vitamin D and calcium combination will cause hypercalcemia and hypercalciuria. Can cause kidney calcification and kidney stone formation. Many stone patients absorb c...
