Description
Technical Field
The invention relates to the technical field of pharmaceutical preparations, in particular to an isoniazid composition and a preparation method thereof.
Background
Tuberculosis is a chronic infectious disease caused by infection of tubercle bacillus, which mainly invades the lung and is called as pulmonary tuberculosis, and is clinically in a chronic process, and has general symptoms of low fever, hypodynamia and the like and respiratory system manifestations of cough, hemoptysis and the like. Isoniazid is an anti-tubercular drug used in the treatment and prevention of various forms of tuberculosis, including tubercular meningitis and other mycobacterial infections. Isoniazid was invented in 1952, and the invention of isoniazid has made a fundamental change in the treatment of tuberculosis.
Isoniazid is colorless crystal or white to off-white crystalline powder, odorless, slightly sweet and bitter, and gradually deteriorates when exposed to light. It is readily soluble in water, slightly soluble in ethanol, and very slightly soluble in diethyl ether. The melting point of the product is 170-173 ℃, and the chemical structural formula is as follows:
the existing isoniazid tablet often has the defect of poor stability, is easy to discolor, deteriorate and the like, and has influence on the safety of the isoniazid tablet.
Therefore, how to provide an isoniazid composition with high quality and good stability becomes a technical problem to be solved urgently by the technical personnel in the field.
Disclosure of Invention
In order to solve the technical problems, the invention provides the isoniazid composition which has good stability, can effectively reduce the generation of related substances, and has the advantages of low cost and easy obtainment because all auxiliary materials used by the composition are conventional auxiliary materials. In addition, the invention also provides a method for preparing the isoniazid composition, which has simple steps and simple and convenient operation and is beneficial to saving the production cost.
The invention provides an isoniazid composition, which comprises the following raw materials: isoniazid, starch, a binder, a disintegrant and polyethylene glycol.
The existing isoniazid composition contains more types of auxiliary materials, and the safety of the isoniazid composition is influenced by incompatibility between some auxiliary materials and main medicines, impurity introduction in the auxiliary materials and the like.
For example, magnesium stearate and isoniazid can undergo maillard reactions which adversely affect the stability of the product. Glyceryl behenate as a lubricant also reacts with isoniazid under certain conditions to affect the stability of the product.
Compared with the prior art, the scheme does not use lactose and magnesium stearate which react with isoniazid, but adopts starch as a filling agent and polyethylene glycol as a lubricating agent; the selected auxiliary materials and the isoniazid have no incompatibility, so that the stability of the isoniazid composition is enhanced.
Preferably, the isoniazid composition comprises the following raw materials in parts by weight: 50-55 parts of isoniazid, 35-40 parts of starch, 1-3 parts of adhesive, 3-8 parts of disintegrating agent and 0.5-3 parts of polyethylene glycol.
Preferably, the isoniazid composition is a tablet.
Preferably, the starch is corn starch.
Preferably, the polyethylene glycol is polyethylene glycol 4000.
Preferably, the isoniazid composition comprises 52-54 parts by weight of isoniazid, 37-39 parts by weight of starch and 5-6 parts by weight of disintegrant.
Preferably, the disintegrating agent is one or more of croscarmellose sodium, sodium carboxymethyl starch, crospovidone, low-substituted hydroxypropyl cellulose, hydroxypropyl starch, sodium alginate, surfactant, silicon dioxide, sodium dodecyl sulfate, magnesium dodecyl sulfate, methylcellulose, glycine, modified starch, malic acid, citric acid, alginic acid, sodium alginate, pregelatinized starch, colloidal silicon dioxide, hydroxyethyl methyl cellulose, magnesium aluminum silicate, microcrystalline cellulose, potassium bicarbonate, sodium bicarbonate, potassium carbonate, sucrose fatty acid ester, sucrose monolaurate, sucrose monopalmitate, potassium dihydrogen phosphate and sodium dihydrogen phosphate;
preferably, the binder is one or more of microcrystalline cellulose, povidone, hypromellose, powdered sugar, dextrin, white dextrin, starch slurry, sucrose, sodium carboxymethyl starch, polyethylene glycol 4000, polyethylene glycol 6000, ethyl cellulose, ethyl methyl cellulose, hydroxyethyl methyl cellulose, hydroxypropyl cellulose, hydroxyethyl cellulose, sodium carboxymethyl cellulose, calcium carboxymethyl cellulose, polymethyl methacrylate, cellulose acetate, polypropylene, polyisobutylene, polyvinyl acetate, sucrose fatty acid ester, sucrose monolaurate, sucrose monopalmitate, acrylic resin, methyl methacrylate, tragacanth, poloxamer, alginic acid, sodium/potassium/calcium alginate, sucrose, acacia slurry, gelatin slurry and carbopol.
Preferably, the adhesive is starch slurry, and the disintegrant is sodium carboxymethyl starch.
According to the isoniazid composition provided by the invention, starch is reasonably selected as a filling agent, starch slurry is used as an adhesive, sodium carboxymethyl starch is used as a disintegrating agent, polyethylene glycol is used as a lubricant, and selected auxiliary materials and isoniazid have no incompatibility, so that the stability of the isoniazid composition is enhanced.
In addition, as isoniazid gradually changes in quality when being exposed to light, the content of effective components is reduced under the condition of light, related substances are increased, and the safety of the isoniazid composition is also affected. In addition to the problem that the stability of the product is affected by the increase of related substances caused by the possible reaction of raw and auxiliary materials, the prior art does not improve the characteristics that isoniazid gradually deteriorates when being exposed to light and has bitter taste, and the quality and the medicine taking compliance of the product are affected.
In order to solve the problem, the isoniazid composition also comprises a coating material.
Preferably, the coating material is 2-5 parts by weight.
Preferably, the weight ratio of the film-forming material to the opacifier to the plasticizer in the coating material is 3-5:2-5: 1.
The invention adopts the film forming material, the opacifier and the plasticizer as the coating material, reduces the degradation of isoniazid by light, reduces the growth of related substances in the isoniazid composition, also effectively covers the bitter taste of isoniazid and improves the taste of the medicine taking. The product stability can be ensured and the generation of related substances can be reduced under the condition of not reducing the bioavailability. In addition, the film coating can reduce the growth of the related substances under non-lighting conditions, probably because the film coating acts as a barrier to oxygen and inhibits the Maillard reaction to some extent.
Preferably, the film forming material is hypromellose, and/or the opacifier is titanium dioxide, and/or the plasticizer is polyethylene glycol.
In addition, the invention also provides a method for preparing the isoniazid composition, which comprises the following steps:
weighing isoniazid according to a proportion, crushing, and sieving by a 40-80 mesh sieve;
mixing the screened isoniazid with starch uniformly,
adding adhesive to granulate, drying and straightening to obtain mixture granules;
adding disintegrating agent and polyethylene glycol, mixing, and tabletting to obtain tablet core.
Preferably, the present invention also provides another method for preparing the isoniazid composition, comprising the steps of:
weighing isoniazid according to a proportion, crushing, and sieving by a 40-80 mesh sieve;
mixing the screened isoniazid with starch uniformly,
adding adhesive to granulate, drying and straightening to obtain mixture granules;
adding disintegrating agent and polyethylene glycol, mixing, and tabletting to obtain tablet core;
uniformly mixing the coating material and purified water;
the tablet cores are coated.
The preparation method of the isoniazid tablet provided by the invention has the advantages that the preparation process is simple, the large-scale production can be realized, the used auxiliary materials are common auxiliary materials, the price is low, and the production cost is favorably saved.
