Background
Azithromycin has the characteristics of wide antibacterial spectrum, small stimulation to gastrointestinal tracts, quick oral absorption and the like, and is widely applied to clinical infectious diseases in recent years.
The azithromycin is mainly used for acute pharyngitis and acute tonsillitis caused by streptococcus pyogenes; sinusitis, otitis media, acute bronchitis and acute attack of chronic bronchitis caused by sensitive bacteria; pneumonia caused by streptococcus pneumoniae, haemophilus influenzae, and mycoplasma pneumoniae; urethritis and cervicitis caused by chlamydia trachomatis and non-multiple drug-resistant neisseria gonorrhoeae; infection of skin soft tissue by sensitive bacteria. The characteristics are as follows: the product is granule or powder; the smell is fragrant.
The dry suspension has the characteristics of a solid preparation, convenient carrying, convenient transportation, good stability and the like, has the advantages of a liquid preparation, is convenient to take and is suitable for patients with swallowing difficulty. Azithromycin is one of the most bitter medicaments known at present, and the existing azithromycin dry suspension has obvious bitter and astringent feeling and poor taste, so that children with mild symptoms are unwilling to take the azithromycin dry suspension, and children with severe symptoms are easy to regurgitate when taking the azithromycin dry suspension, so that the children are difficult to take the azithromycin dry suspension, and the drug effect is influenced.
Disclosure of Invention
The invention provides a preparation method of a dry suspension containing azithromycin, which is used for binding and wrapping particles, thereby achieving the effects of effectively masking taste and improving the bitter taste of the azithromycin and enhancing the administration compliance of patients, particularly children patients.
The technical scheme provided by the invention is as follows:
a dry suspension containing azithromycin is prepared from the following raw materials in parts by weight: 100-110 parts of azithromycin, 1800-1900 parts of cane sugar, 9-9.5 parts of anhydrous trisodium phosphate, 33-33.5 parts of hydroxypropyl cellulose, 33-33.5 parts of xanthan gum, 12-13 parts of banana powder essence, 12-13 parts of cherry powder essence and 12-13 parts of vanilla powder essence.
Further, the feed is prepared from the following raw materials in parts by weight: 104.81 parts of azithromycin, 1882.03 parts of cane sugar, 9.00 parts of anhydrous trisodium phosphate, 33.33 parts of hydroxypropyl cellulose, 33.33 parts of xanthan gum, 12.50 parts of banana powder essence, 12.50 parts of cherry powder essence and 12.50 parts of vanilla powder essence.
The invention also provides a preparation method of the azithromycin-containing dry suspension, which comprises the following steps:
placing sucrose and azithromycin into a fluidized bed granulator, gradually pumping a granulating liquid through a peristaltic pump, carrying out fluidized bed granulation and granule coating, carrying out granule finishing on the granules to obtain dry granules, adding anhydrous trisodium phosphate and essence into the dry granules, and mixing in a three-dimensional mixer to obtain a dry suspension containing azithromycin; the adhesive is a mixed solution of hydroxypropyl cellulose and xanthan gum.
Further, in the granulating liquid, the concentration of hydroxypropyl cellulose is 0.15-15.0%; the concentration of the xanthan gum is 0.15-15.0%.
Further, the material temperature is controlled to be 35-45 ℃ in the production process.
Further, the sucrose is crushed by a powder grinding device and is sieved by a 80-mesh sieve.
Further, the parameters of the fluid bed granulator are as follows: air inlet temperature: 40-60 ℃; material temperature: 35-45 ℃; the rotating speed of the air exhaust fan is as follows: 800-1100 rpm; liquid inlet speed: 3-7 rpm; atomization pressure: 0.15 to 0.20 MPa.
Further, the preparation method of the granulating liquid comprises the following steps: precisely weighing 26.67 parts by mass of water, precisely weighing 3.33 parts by mass of hydroxypropyl cellulose and 3.33 parts by mass of xanthan gum, adding into a beaker, and continuously and magnetically stirring until the hydroxypropyl cellulose and the xanthan gum are completely dissolved to obtain a granulation liquid.
Furthermore, the mesh size of the whole grain is phi 0.8mm, and the frequency is 30 Hz.
Further, the mixing frequency of the three-dimensional mixer was 45Hz, and the mixing time was 15 min.
Advantageous effects
Xanthan gum is widely used as a suspending and stabilizing agent in oral and topical pharmaceutical preparations, cosmetics and foodstuffs, as well as a thickening and emulsifying agent. The product has no toxicity, can be combined with most of medicinal adjuvants, and has good stability and viscosity in wide pH and temperature range.
Hydroxypropyl cellulose is abbreviated as HPC, is white or light yellow powder, is tasteless and combustible, and is a nonionic cellulose derivative. Good thermoplasticity, film-forming property, cohesiveness, latex stability and dispersivity, and little ash content. It is mainly used as tablet binder, film coating, etc. in medicine, and also can be used as cosmetic, X-ray photographic developer, tackifier, dispersant, etc.
According to the invention, fluidized bed granulation and particle coating are completed, the temperature of the materials is controlled to be 35-45 ℃, so that the granulation liquid solution prepared from xanthan gum and hydroxypropyl cellulose can be bonded and coated with particles, thereby achieving the effects of effectively masking taste, improving the bitter taste of azithromycin and enhancing the administration compliance of patients, especially children patients.

Evaluation:
comparison of powder Properties
Taste masking effect comparison:
dissolution profile and similarity comparison (ph6.4 phosphate medium):
in summary, the formulas prepared in example 1 and example 2 both had good flowability, and in terms of taste, blind tests showed that: example 2 has very weak bitter taste and obvious sweet taste, and can obviously achieve the taste masking effect, while the preparation prepared in example 1 has very bitter taste and poor taste masking effect.
Example 1 used a wet granulation process that differentiated the dissolution in a force medium from the factor f2 up to 72.47 similar to the reference formulation, example 2 used a fluid bed granulation and granule coating process that exhibited a dissolution from the factor f2 up to 79.11 similar to the reference formulation, and the formulations prepared in both examples were very similar to the reference formulation, but directly affected patient compliance due to taste masking effects. The taste masking effect is good, the clinical curative effect is positive, the taste masking effect is poor, and the influence on the clinical curative effect is negative. Therefore, we determined that the fluidized bed granulation and granule coating process of example 2 had good taste masking effect and the formulation technique was more successful.

Comparison of powder Properties
Taste masking effect comparison:
dissolution profile and similarity comparison (ph6.4 phosphate medium):
in summary, the formulas prepared in examples 3 and 4 respectively have better fluidity by adjusting the proportion of the hydroxypropyl cellulose to the xanthan gum, but the blind tests show that: example 3 has a significant bitterness, a high hydroxypropyl cellulose concentration, a low xanthan gum concentration, and a good granulation effect, but the granule coating effect is not significant and the taste masking effect is not good. Example 4 had a slightly bitter taste, low hydroxypropyl cellulose concentration, high xanthan gum concentration, poor granulation effect, more fine powder present, and no significant taste masking effect.
Meanwhile, the dissolution in example 3 was slow, and the dissolution in example 4 was fast, and it is highly probable that the granulation effect affects the particle size distribution, and the dissolution was slightly slow in example 3 in which the large particle content was large, and excessively fast in example 4 in which the fine powder content was large.
Therefore, we determined that example 2 is superior to examples 3 and 4, and that the formulation and formulation process was more successful in taste masking.
