Problems solved by technology

However, formulations swallowed whole are also unsuitable for children or patients who have difficulty swallowing, and suspensions that dissolve in water or disperse into fine particles must be used, such as soluble tablets, granules, solutions, or suspensions
However, due to exposure, the medicine in this dosage form will inevitably come into direct contact with the taste buds on the oral cavity when taking it, so the bad smell or taste of the medicine can often be felt when taking it.

Embodiment 1

[0020] Heat 2 parts of glyceryl monostearate to 90°C to melt, then mix 1 part of azithromycin powder, under the protection of nitrogen, keep the temperature at 85-95°C, stir well, so that azithromycin is evenly dispersed in glyceryl monostearate; The molten material of the above-mentioned medicine and auxiliary materials is frozen and sprayed under heat preservation, the temperature of the spray air inlet is 20°C, and the air temperature of the air outlet is about 30-36°C, and the microspheres are collected. The microspheres were sieved with a 40-mesh sieve to debond large pieces to obtain powdery taste-masking microspheres.

Embodiment 2

[0022] Heat 3.5 parts of carnauba wax at 100°C to melt, then mix 1 part of azithromycin powder, under the protection of nitrogen, keep the temperature at 90-100°C, stir well, so that azithromycin is uniformly dispersed in carnauba wax; mix the above drugs and excipients The molten material is frozen and sprayed under heat preservation, the temperature of the spray air inlet is 25°C, and the temperature of the air at the outlet is about 32-40°C, and the microspheres are collected. The microspheres were sieved with a 60-mesh sieve to debond large pieces to obtain powdery taste-masking microspheres.

Embodiment 3

[0024] Heat 10 parts of stearyl alcohol to 70°C to melt, then mix 1 part of azithromycin powder, under the protection of nitrogen, keep the temperature at 70-80°C, stir well, so that azithromycin is uniformly dispersed in stearyl alcohol; The molten material is frozen and sprayed under heat preservation, the temperature of the spray air inlet is 15°C, and the temperature of the air at the outlet is about 22-28°C, and the microspheres are collected. The microspheres were sieved with an 80-mesh sieve to debond large pieces to obtain powdery taste-masking microspheres.

Abstract

The invention relates to a preparation method of azithromycin taste-masking microspheres. After azithromycin and an auxiliary material are heated and melted, then melt is frozen and atomized, the grain sizes of the obtained microspheres are smaller than the grain sizes of microspheres obtained by common wet granulation or hot melting extrusion and granulation, less prepared microspheres are dissolved in water within a short time, the taste-masking effect is good, moreover, because the grain size is small and the particles are smooth, a patient does not have sandy feeling when orally taking theazithromycin taste-masking microspheres, oral taking is facilitated, the patient easily receives the azithromycin taste-masking microspheres, moreover, the production process is simple, and production is facilitated.

Description

【Technical field】 [0001] The invention relates to an antibiotic drug, in particular to a preparation method of azithromycin taste-masking microspheres. 【Background technique】 [0002] Many medicines have certain peculiar smells, such as bitterness, special smell, numbness and so on. These medicines with unacceptable taste are usually made into solid preparations swallowed as a whole, such as coated tablets and capsules. However, formulations swallowed whole are also unsuitable for children or patients who have difficulty swallowing, and suspensions that can be dissolved in water or dispersed into fine particles must be used, such as soluble tablets, granules, solutions or suspensions. But because the medicine in this dosage form is exposed to the outside, it will inevitably directly contact with the taste buds on the oral cavity when taking it, so the bad smell or taste of the medicine can often be felt when taking it. [0003] In the methods of the prior art, the taste-ma...
