Example Embodiment

[0047] Embodiment 1-4, tablet

[0048] The pharmaceutical composition of the present invention, the preferred formula composition is as follows: prescription (amount of 1000 tablets, unit: g)

[0049]

[0050] The composition preparation method of the present invention comprises the following steps:

[0051] a) dissolve poloxamer and meglumine in 50% ethanol, add repaglinide, and add povidone after dissolving;

[0052] b) pulverizing metformin hydrochloride through a 60-mesh sieve, and mannitol through a 30-mesh sieve, for subsequent use;

[0053] c) Weigh the recipe quantities of metformin hydrochloride, microcrystalline cellulose, crospovidone, mannitol and polyethylene glycol 6000 and place them in the fluidized bed, and set the inlet air volume to 500±200m 3 / h, the inlet air temperature is 90±5℃, the product temperature is 70±5℃, and hot melt granulation is performed;

[0054] d) spray the repaglinide solution into the fluidized bed, set the atomization pressure to ...

Example Embodiment

[0059] Embodiment 5-6, the tablet of the present invention

[0060]

[0061] The composition preparation method of the present invention comprises the following steps:

[0062] a) dissolve poloxamer and meglumine in 50% ethanol, add repaglinide, and add povidone after dissolving;

[0063] b) pulverizing metformin hydrochloride through a 60-mesh sieve, and mannitol through a 30-mesh sieve, for subsequent use;

[0064] c) Weigh the recipe quantities of metformin hydrochloride, microcrystalline cellulose, crospovidone, mannitol and polyethylene glycol 6000 and place them in the fluidized bed, and set the inlet air volume to 500±200m 3 / h, the inlet air temperature is 90±5℃, the product temperature is 70±5℃, and hot melt granulation is performed;

[0065] d) spray the repaglinide solution into the fluidized bed, set the atomization pressure to 1.0 ± 0.2 bar and the spray speed to 30 ± 10 Hz, and perform one-step granulation;

[0066] e) pass the prepared granules through a 1...

Example Embodiment

[0070] Experimental Example 1. Determination of physical properties of the granules and tablets of the present invention

[0071] Get the granule and tablet of above-mentioned embodiment 1-6, carry out granule fluidity, tablet hardness, friability test

[0072] The measurement results of particle fluidity (angle of repose), bulk density, tapped density, tablet hardness, and friability are shown in the following table:

[0073]

[0074] From the results in the above table, it can be seen that the particle fluidity of Examples 1-6 is not much different, the tablet hardness is suitable, and the friability is small.

Abstract

The invention provides a medicinal composition including active components of repaglinide and metformin hydrochloride, and its preparation method. The method comprises the following steps: carrying out hot melting granulation of metformin hydrochloride to prepare particles, directly spraying a repaglinide solution on the metformin hydrochloride particles through a one-step granulation technology, and adding parts of auxiliary materials to prepare a tablet.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and more specifically relates to a pharmaceutical composition containing repaglinide and metformin hydrochloride and a preparation method thereof. Background technique [0002] The incidence of diabetes is increasing year by year, and China has become the hardest hit area, and the number of diabetic patients ranks second in the world. According to pathological characteristics, diabetes can be divided into two types: type 1 diabetes, namely insulin-dependent (IDDM) diabetes, patients of this type must rely on exogenous insulin to maintain life, and most of them are severe; type 2 diabetes, that is, non-insulin-dependent diabetes (NIDDM) Diabetes, this type of patients do not need to rely on exogenous insulin to maintain life, most of them are adults, but can also be seen in adolescents, most of the patients are obese, insulin receptors are not sensitive, this type accounts for at least 8...
