Problems solved by technology

Changes in disintegration time and dissolution rate greatly affect the oral absorption and peak blood concentration time of this product, and there are risks to the safety and effectiveness of the drug
At present, the storage conditions of "shading, sealing, and storage below 30°C" are used, which warns of the risk of quality change of acipimus capsules, but puts forward high requirements for production, transportation, sales, and home storage and use, and it is difficult to guarantee the drug. The contents are reasonably preserved, and the patient's drug efficacy is uncertain

[0038] Embodiments 1 to 3 are comparative experiments on the effects of preparing acipimus spacers using different preparation methods.

[0039] Preparation of acipimus spacer by grinding method

[0040] Experimental scheme: After uniformly mixing acipimox and solubilizer, add release agent according to the type and amount of release agent recorded in Table 1, and grind thoroughly. The isolation is considered successful when the mixed powder of acipimox and the isolation agent no longer forms a cohesive substance immediately when it meets water. The lubricant can be one or more of magnesium stearate, micronized silica gel, and talcum powder. The isolation effect is shown in Table 1. In the mixture of povidone and silicon dioxide in Table 1,

Embodiment 1

[0057] The formula of acipimox capsule of the present embodiment is as follows:

[0058]

[0059] Preparation of acipimox capsules by wet granulation: dissolving the sodium lauryl sulfate in the prescribed amount in 50% ethanol, adding to the raw material of acipimox, and stirring to make wet and soft materials. The amount of 50% ethanol added is subject to the form that can form wet and soft materials. Then add hydrogenated castor oil and silicon dioxide and continue to stir for 5 minutes, pass through a 24-mesh sieve to granulate, dry at 50°C until the water content is ≤5%, and granulate. Mix well with sodium carboxymethyl cellulose and talcum powder. Using a disc-type capsule filling machine, select No. 1 capsule for filling.

[0060] In this embodiment: the release agent is: hydrogenated castor oil and silicon dioxide. The disintegrant is: sodium carboxymethylcellulose; the lubricant is: talc; the solubilizer is: sodium lauryl sulfate.

Embodiment 2

[0062] The formula of acipimox capsule of the present embodiment is as follows:

[0063]

[0064] Preparation of acipimox capsules by dry granulation

[0065] Preparation steps: Detect the moisture content of each material in the formula, keep it below 5.5%, and set aside. After mixing the formulated amount of acipimox and poloxamer evenly, fully mix and grind with silicon dioxide and povidone, when the mixed powder of acipimox and release agent no longer forms a bond immediately when it meets water, After mixing evenly with the formula amount of croscarmellose sodium, a dry granulator is used to prepare 24-80 mesh granules, and the prepared granules are mixed evenly with crospovidone, magnesium stearate, and talcum powder, and Multi-punch filling capsule filling machine, 0 capsules for filling.

[0066] In this embodiment: the release agent is: silicon dioxide and povidone. The disintegrants are: croscarmellose sodium and crospovidone; the lubricants are: magnesium stea...

Abstract

The invention provides an acipimox capsule. The acipimox capsule is characterized by comprising components in parts by weight as follows: 250 parts of acipimox, 30-100 parts of an isolating agent and 5-20 parts of a disintegrating agent. According to the acipimox capsule and a preparation method thereof, acipimox particles are effectively isolated by adopting a specific auxiliary material, and the characteristic that the acipimox particles are easy to stick is improved.

Description

technical field [0001] The invention relates to an acipimox capsule, and also relates to a preparation method of the acipimox capsule, which belongs to the field of medicine. Background technique [0002] Acipimox, chemical name: 4-oxo-5-methylpyrazine-2-carboxylic acid; molecular formula: C6H6N2O3; molecular weight: 154.12; its structural formula is as follows: [0003] [0004] Acilimus was developed by Italian Farmitalia Carlo Erba Company, the patent number is US4002750 (1977), it is used for various primary and secondary hyperlipidemia, it can reduce plasma total cholesterol, triglyceride, low density lipid Protein and very low-density lipoprotein content, increase high-density lipoprotein content. It can inhibit the release of free fatty acids from adipose tissue, reduce the blood concentration of very low-density lipoprotein and low-density lipoprotein, reduce the level of triglyceride and total cholesterol in the blood, and increase the amount of high-density lip...
