Description

The preparation method of amoxil capsule
Technical field
The present invention relates to pharmaceutical fields, and in particular to a kind of preparation method of amoxil capsule.
Background technology
Amoxicillin also known as amoxicillin or Amoxicillin are that a kind of most common semi-synthetic penicillins wide spectrum β-is interior Amides antibiotic is a kind of white powder, and half-life period is about 61.3 minutes.Stablize in acid condition, gastrointestinal tract absorptivity Up to 90%.Amoxicillin bactericidal effect is strong, and the ability of penetration cell film is also strong.It is widely used at present oral semi-synthetic One of penicillin, preparation have capsule, tablet, granule, dispersible tablet etc., are often shared now with clavulanic acid and dispersion is made Piece.Exactly because half-life short in vivo, and drained comparatively fast through urinary tract, drug availability is low, takes rear blood concentration and reaches Peak time is about 2 hours, and blood concentration is rapidly decreased to minimum inhibitory concentration hereinafter, needing to take in drug again and could maintain later Blood concentration, it is clear that the times for spraying of general Amoxicillin medicament is more.For such situation, prior art preparation has gone out energy Enough control the sustained release preparation of Amoxicillin rate of release.But there is setting in glue in existing sustained release preparation especially capsule preparations The Amoxicillin in intracapsular portion exists in the form of granules, although its external capsule has centainly the dissolving of Amoxicillin Slow release effect, but its solution rate could promote slow release effect there is still a need for being controlled.
Therefore clinically need a kind of Amoxicillin existence form that can be improved in amoxil capsule further to carry Rise the dosage form of slow release effect.
Invention content
The purpose of the present invention is to provide a kind of preparation method of amoxil capsule, which passes through to A Moxi The improvement of Wymox form in woods capsule so that the particle diameter distribution of Amoxicillin micro-capsule is narrow, and embedding rate is big.The present invention Amoxil capsule and reference preparation have similitude, 4 In Vitro Dissolutions of amoxil capsule of the invention and reference preparation Curve F2 values are all higher than 50.
The present invention is achieved through the following technical solutions:
The preparation method of amoxil capsule, includes the following steps:
(1) Amoxicillin micro-capsule is prepared:Wall material solution, Amoxicillin are added in emulsifier solution, constant temperature water bath is stirred A period of time carries out homogenization and obtains mixed liquor, and mixed liquor is sprayed in solidify liquid, and the drop ejected is at once and solidify liquid Contact, and it is passed through 6~8mL/min air from solidify liquid bottom, the mass concentration of solidify liquid is 15~20%, and drop is in solidify liquid Amoxicillin micro-capsule is isolated after 10~15min of solidification, it is spare to clean dehydration and drying;
(2) amoxil capsule is prepared:Amoxicillin micro-capsule in step (1) is divided in capsule for medicine by weight It is interior.
The second wall material can be added in solidify liquid.
Solidify liquid is calcium chloride solution.
The wall material of Amoxicillin micro-capsule is Arabic gum, sodium alginate or hydroxypropyl methyl cellulose, beta-cyclodextrin.
Second wall material is ethyl cellulose and sodium carboxymethylcellulose.
Second wall material, wall material, Amoxicillin mass ratio are 2:1:0.8~1.
The mass concentration of solidify liquid is 15~18%.
The preparation of micro-capsule and the preparation difference of the prior art are in the present invention:The present invention is directly and solid after drop ejection Change liquid contact, so that drop enables to drop to cure uniform force under the action of solidify liquid and air, accelerates cured same When and enable to droplet particles mellow and full, particle diameter distribution is narrow, even particle size, and the single defect in surface is few, and embedding rate is big, Cause molding micro-capsule surface area smaller in this way.Existing drop one spray directly by gravity cause drop single first by Gravity and the guiding deformation of a degree of gravity occurs, cause follow-up particle diameter distribution wider.It is passed through from solidify liquid bottom Air, which can play the role of also residing in, can stir solidify liquid so that solidify liquid gives drop shearing force appropriate.The present invention Middle drop ejection can be in the top of solidify liquid, and drop is to be sprayed straight down.
The second wall material is added in solidify liquid, drop is enabled to be wrapped up for the second time, that is, provides outside the drop second layer Shell improves slow releasing function.
The wall material of Amoxicillin may be selected to be suitble to its any materials.Arabic gum, sea are selected in the present invention Mosanom or hydroxypropyl methyl cellulose, beta-cyclodextrin.Arabic gum, sodium alginate or hydroxypropyl methyl cellulose, β- The mass ratio of cyclodextrin is with 3:3:1 is more suitable.Second wall material selects ethyl cellulose and sodium carboxymethylcellulose.Carboxymethyl is fine The plain sodium of dimension plays the role of promoting Amoxicillin dissolving, in the presence of the second wall material, it is necessary to appropriate to promote the molten of Amoxicillin Xie Du so that its slow release effect obtains a degree of balance.Ethyl cellulose and sodium carboxymethylcellulose mass ratio are 3:1 compared with It is suitable.
In the present invention wall material solution according to conventional aqueous preparation method.Solidify liquid is not limited to chlorine in the present invention Change calcium, other suitable solidify liquids can be applicable in.Wall material mass concentration is 1.5~3%.Emulsifier is the common breast in this field Agent can be that monoglyceride either takes charge of temperature or tween etc..
Compared with prior art, the present invention having the following advantages and advantages:
The present invention is improved by the form to the Amoxicillin agent in amoxil capsule, especially by Amoxicillin Particle is modified to micro-capsule, while being improved to the preparation method of Amoxicillin micro-capsule so that the grain size of Amoxicillin micro-capsule point Cloth is narrow, and embedding rate is big, improves slow release effect.
