Description
Technical Field
The invention relates to the technical field of veterinary medicine preparations, in particular to a telavancin tartrate nano preparation and a preparation method thereof.
Background
The tylosin tartrate (also called acetylisovaleryl tylosin tartrate) is a new generation of macrolide medicine, and is synthesized by taking tylosin as a raw material through acetylation, isovalerylation and alcoholysis reactions. The medicine is the only medicine which can really reach the bronchus cavity and kill mycoplasma, the antibacterial potency of the medicine is 5-10 times of that of tylosin, and 2-5 times of tilmicosin; the alkaline side chain can effectively change the intracellular pH value, inhibit the propagation of blue-ear virus, and is commonly used for preventing and treating mycoplasma diseases (swine enzootic pneumonia, chicken slow breathing), swine blue-ear diseases, swine proliferative ileitis, infectious pleuropneumonia, streptococcosis and other diseases of livestock and poultry. In addition, the novel compound bacterium has the functions of enhancing nonspecific immunity and inhibiting replication and growth promotion of blue-ear disease viruses in macrophages, is a totipotent antibiotic suitable for large-scale farms, and has wide market application prospect.
The tylosin tartrate dissolves slowly when being applied to cultivation, is easy to agglomerate, has poor water solubility and has great bitter taste and irritation. Although the existing commercial tylosin tartrate preparation is improved in terms of changing the solubility, stability and taste masking effect of the medicine, the taste masking effect of the existing prepared tylosin tartrate preparation cannot meet the actual requirements of farms because of extremely bitter taste of the tylosin tartrate, and is not beneficial to feeding. In addition, the particle size of the prepared telavancin tartrate preparation is larger, most of the particles are in a micron level, the preparation method is still required to be further simplified to better realize industrialization, and meanwhile, the stability and the water solubility are still required to be further improved.
Therefore, there is a need in the art for a tylosin tartrate preparation which combines drug solubility, stability and palatability, has smaller particle size, simple preparation process and easy realization of industrialization.
Disclosure of Invention

TABLE 3 solubility data of the Tawansin tartrate nano-formulations of the invention and the existing Tawansin tartrate formulations at concentrations of 0.04-0.06g/mL
As can be seen from tables 1 and 2, the defoaming time of the tylosin tartrate nano-formulations of examples 1 to 3 of the present invention at the concentrations of 0.01g/mL, 0.02g/mL, 0.03g/mL, 0.04g/mL, 0.05g/mL, 0.06g/mL were 4s, 5s, 7s, respectively, whereas the defoaming time of the commercially available product 1 at the concentrations of 0.01g/mL, 0.02g/mL, 0.03g/mL, 0.04g/mL were 10s, 15s, 30s, respectively, and the defoaming time of the commercially available product 2 at the concentrations of 0.01g/mL, 0.02g/mL, 0.03g/mL, 0.04g/mL, 0.05g/mL, 0.06g/mL was 5s, 8s, 11s, 15s, 21s, respectively, which is significantly shorter than that of the commercially available product.
In addition, the tylosin tartrate nano preparation of the embodiment 1-3 of the invention can realize complete dissolution when being hand-operated for 20s-1min at the concentration of 0.01-0.06g/mL, and the time required for complete dissolution at the concentrations of 0.01g/mL, 0.02g/mL, 0.03g/mL, 0.04g/mL, 0.05g/mL and 0.06g/mL is respectively 25-45s, 1-1.5min, 1.5-2min, 2-3min, 2.6-4.5min and 3.2-6min, while the solution is still relatively turbid when the commercial product 1 is hand-operated for 2-6min at the concentration of 0.02-0.04g/mL, and the time required for complete dissolution at the concentration of 0.01g/mL is 4-7.2 times of the time required for complete dissolution (25-45 s) of the tylosin tartrate nano preparation of the invention when being hand-operated for 20 s; when the commercial product 2 is hand-operated for 10-25min at the concentration of 0.05-0.06g/mL, the solution is still turbid and can not be completely dissolved, the time required for complete dissolution at the concentration of 0.01g/mL, 0.02g/mL, 0.03g/mL and 0.04g/mL is respectively 2min, 5min, 10min and 16min, which are far longer than the time required for complete dissolution of the telavancin tartrate nano preparation (25-45 s, 1-1.5min, 1.5-2min and 2-3 min) at the same concentration, and the time required for complete dissolution at the concentration of 0.01g/mL (2 min) is 2.7-4.8 times the time required for complete dissolution of the telavancin tartrate nano preparation (25-45 s). Therefore, under the same conditions, the time required for complete dissolution of the telavancin tartrate nano-preparation provided by the invention is obviously shortened compared with that of a commercially available product.
In conclusion, compared with the commercial products, the defoaming time and the complete dissolution time of the telavancin tartrate nano preparation are obviously shortened, and the solubility is obviously improved.
In addition, compared with example 2, the mixed solution C prepared in comparative example 1, to which no hydroxypropyl-beta-cyclodextrin was added, had much of the tayloxacin tartrate as a raw material, and the spray nozzle was blocked during spray drying, so that no preparation could be prepared, indicating that the amount of hydroxypropyl-beta-cyclodextrin had a large influence on the dissolution of the tayloxacin tartrate as a raw material of the preparation.
Comparing the solubility data of examples 1-3 of the present invention in tables 2 and 3, it can be seen that the tavancin tartrate nano-formulation prepared in example 2 has a shorter dissolution time and the best solubility under the same hand shaking time and concentration. The preferred telavancin tartrate nano-formulation prepared in the preferred embodiment 2 of the present invention is the preferred telavancin tartrate nano-formulation of the present invention.
Test 2: 1g, 3g and 6g of the telavancin tartrate nano-preparation powder prepared in the embodiment 2 of the invention, a commercial product 1 and a commercial product 2 are respectively taken and added into 100mL of water, and the mixture is respectively hand-operated for 20s, 35s and 60s, then respectively kept stand for 29s, 94s and 199s, and a picture of the dissolution state of each preparation is taken.

As seen in FIG. 5, the telavancin tartrate nano-formulation of the present invention was completely dissolved when left to stand for 29s at a concentration of 0.01g/mL, the solution was clear and transparent, completely defoamed, while the solutions of commercial products 1 and 2 were slightly cloudy, not completely dissolved, and more air bubbles were present above the solution. When the nano preparation of the telavancin tartrate is stood for 94 seconds at the concentration of 0.03g/mL, the solution is clear and transparent and is completely defoamed, the solution of the commercial product 1 is cloudy and is not completely dissolved, more bubbles are arranged above the solution, the solution of the commercial product 2 is slightly cloudy and is not completely dissolved, and more bubbles are arranged above the solution. When the nano preparation of the telavancin tartrate is stood for 199 seconds at the concentration of 0.06g/mL, the solution is clear and transparent and is completely defoamed, the solutions of the commercial products 1 and 2 are turbid, the solution is not completely dissolved, and a few bubbles exist above the solution. Therefore, the solubility of the telavancin tartrate nano preparation provided by the invention under the same conditions is obviously superior to that of the commercial product.
