TECHNICAL FIELD
[0001] The application belongs to the technical field of pharmaceutical preparations, and particularly relates to a sucrose hydroxyl ferric oxide chewable tablet and a preparation method thereof. BACKGROUND
[0002] Hyperphosphatemia refers to a condition in which the phosphate concentration in the blood is higher than the normal level, which is a common complication in patients with chronic kidney disease or end-stage renal disease with severely impaired kidney function. Hyperphosphatemia itself has no obvious symptoms, but a long-term high phosphate concentration in the blood can affect calcium phosphate deposition, causing hypocalcemia, and further causing secondary hyperthyroidism, renal osteopathy and other diseases, and can also cause serious cardiovascular complications. Kidney is an important organ responsible for regulating phosphate balance, and when the kidney function is severely impaired, phosphate cannot be fully excreted from the body. Therefore, hyperphosphatemia is also a common condition in patients with chronic kidney disease (CKD), especially hemodialysis patients.
[0003] Currently approved phosphate binders for the treatment of hyperphosphatemia include calcium-based, lanthanum-based and anion exchange resin products. Sucrose hydroxyl ferric oxide chewable tablet is the first iron-based phosphate binder, which has strong phosphate binding capacity, high blood phosphorus standard rate, does not affect the absorption of vitamin D, reduces the burden of intravenous medication, has a small amount of iron absorption, maintains stable iron parameters, reduces iron supplement and other advantages. The iron (III)-ferric hydroxide in the product is almost insoluble, and has high phosphate adsorption capacity and low iron release.
[0004] Sucrose hydroxyl ferric oxide chewable tablet is developed by Vifor Fresenius, and the trade name is Velphoro, and the specification is 0.5g (calculated as Fe). In the United States, the European Union and Japan, there are related products on the market, and the domestic has approved the original research import. The patent CN201480065206.0 of Vifor discloses a prescription preparation method of sucrose hydroxyl ferric oxide chewable tablet, and the preparation method of the chewable tablet is a powder direct compression process. The raw material with a particle size D50 less than 40um is used to prepare the prescription by the powder direct compression process, and there is a bitter rush phenomenon during tabletting, so it is necessary to optimize the prescription process of sucrose hydroxyl ferric oxide chewable tablet to improve the bitter rush phenomenon during tabletting. SUMMARY
[0005] The purpose of the present application is to provide a sucrose hydroxyl ferric oxide chewable tablet and a preparation method thereof, which can effectively improve the bitter rush phenomenon during tabletting in the prescription preparation process.
[0006] The present application is implemented by the following technical means:
[0007] The present application provides a sucrose hydroxyl ferric oxide chewable tablet, which is prepared by adding a lubricant to a total mixture after dry granulation of sucrose hydroxyl ferric oxide, a glidant, a lubricant, a flavoring agent and a room fragrance agent.
[0008] The sucrose hydroxyl ferric oxide chewable tablet is composed of the following ingredients by weight ratio:
[0009] Sucrose hydroxyl ferric oxide 2000-2500 parts
[0010] Glidant 10-20 parts
[0011] Lubricant 20-40 parts
[0012] Flavoring agent 30-50 parts
[0013] Fragrance 10-20 parts
[0014] Further, the sucrose hydroxyl ferric oxide contains a mixture of hydroxyl ferric oxide (III), sucrose and one or more starches, and the particle size distribution D50 thereof should be less than 40 μm.
[0015] Further, the glidant is colloidal silicon dioxide.
[0016] Further, the lubricant is one or more of magnesium stearate, calcium stearate, sodium stearate fumarate, and talc.
[0017] The present application also provides a preparation method for the above-mentioned sucrose hydroxyl ferric oxide chewable tablet, which specifically comprises the following steps:
[0018] (1) Premixing: uniformly mix the sucrose hydroxyl ferric oxide, glidant, lubricant, flavoring agent, and fragrance;
[0019] (2) Dry granulation: dry granulate the premixing material of step (1) and sieve the granules through an 80-100 mesh screen;
[0020] (3) Total mixing: mix the granules prepared in step (2) with the lubricant to obtain the total mixing material;
[0021] (4) Tabletting: tablet the total mixing material obtained in step (3), and spray magnesium stearate during the tabletting process.
[0022] The present application has the following advantages:
[0023] The sucrose hydroxyl ferric oxide chewable tablet preparation method provided by the present application uses raw material drugs with a particle size distribution D50 of less than 40 μm to prepare the prescription, which improves the problem of too small particle size of the raw material drugs through the dry granulation process, and uses magnesium stearate and talc as lubricants, and sprays magnesium stearate during the tabletting process, which effectively improves the chocking phenomenon during the tabletting process.

[0092]
[0093]
[0094] It can be seen that the sucrose ferric oxyhydroxide chewable tablet provided by the present application has more uniform and smooth color on the tablet surface, and good appearance compared with the comparative example.
