Abstract
The invention relates to cefpodoxime proxetil particles and a preparation method thereof, and relates to the field of pharmaceutical preparations. The research shows that the stability of the cefpodoxime proxetil particles prepared after the sucrose coating is obviously improved.

Experiment one: compatibility test of raw materials and auxiliary materials
Because the auxiliary materials are more in the product, the auxiliary materials are grouped, the raw material medicines are respectively and uniformly mixed with each group of auxiliary materials, and then the raw material medicines are respectively placed in a culture dish to be spread into thin layers with the thickness of less than 5 mm. The specific grouping of the excipients is shown in table 3 below.

Note: N.D.: it was not detected.
The experimental results show that the cefpodoxime proxetil bulk drug has poor stability under the conditions of high temperature (60 +/-2 ℃) and illumination (4500 lx +/-500 lx); the bulk drug and the sucrose (sample 1) are placed for 10 days and 30 days under the conditions of high temperature and illumination, and the increase range of impurities C + B-II + D-I and total impurities is larger than that of the bulk drug (sample 6); the crude drug and other auxiliary materials (samples 2-4) are placed for 10 days and 30 days under the conditions of high temperature and illumination, and the increment of impurities C + B-II + D-I and total impurities is lower than that of the crude drug of cefpodoxime proxetil; the total auxiliary material and cefpodoxime proxetil (sample 5) contain sucrose, so that the increase range of impurities C + B-II + D-I and total impurities is larger than that of other auxiliary materials (samples 2-4), the stability is reduced due to the existence of sucrose, but the total auxiliary materials also have a protective effect on the bulk drugs, and the total auxiliary materials are slightly lower than the impurities of the raw materials.

TABLE 9 compatibility test results (illumination (4500 lx +/-500 lx))
Note: N.D.: it was not detected.
From the experimental results, the raw material medicines and the cane sugar prepared by the two preparation processes are placed for 10 days and 30 days under the conditions of high temperature and illumination, the increase amplitudes of the impurities C + B-II + D-I and the total impurities are basically consistent and are both larger than those of the raw material medicines; the results show that the sucrose prepared by different preparation processes has basically the same influence on the stability of the bulk drug, so the problem of compatibility of the two needs to be solved from the process perspective.
Has the advantages that:
the inventor has found through intensive research that the stability of cefpodoxime proxetil particles prepared after sucrose coating is obviously improved, and meanwhile, the dissolution meets the requirement.
Specifically, the method comprises the following steps:
the inventors have discovered, by chance and after numerous experiments, that only the bulking agent sucrose is mixed with cefpodoxime proxetil, namely: after the sucrose is directly contacted with the bulk drug, the mixture is placed for 30 days under the conditions of high temperature (60 +/-2 ℃) or illumination (4500 +/-500 lx), and the increase range of the impurities C + B-II + D-I and the total impurities is larger than that of the bulk drug, wherein the impurity B is a process impurity, the impurity C is a thermal degradation impurity, and the impurity D is a photo degradation impurity, which indicates that the sucrose is a key factor influencing the stability of cefpodoxime proxetil.
The original drug of the study (oreloc) was sucrose and lactose (about 20 weight ratio 1), both of which served as diluents, with lactose being a minor component. CN 104771368 aims at solving the problem that the preparation is low in dissolution when dissolved in water. The cefpodoxime proxetil and the surfactant are uniformly dispersed on the surface and inside the particles after granulation and drying, when the medicinal preparation is added into an aqueous dissolution medium, the water-soluble auxiliary material and part of cefpodoxime proxetil are quickly dissolved, the surfactant can be quickly distributed on the surface of the residual undissolved medicament, a specific hydrophilic group of the surfactant extends outwards to combine with water molecules, a hydrophobic group surrounds the surface of the cefpodoxime proxetil, and the medicament molecules are separated one by one, so that the tendency of gelation of the medicament can be effectively avoided, and the dissolution of the cefpodoxime proxetil is accelerated. The experimental results mainly examine the influence of the surfactant. Because the prescription is added with the surfactant, the sucrose and the lactose of the original medicine cannot be diluted well, and particularly, the sucrose and the lactose are difficult to granulate under the condition of large sucrose amount, so the weight ratio of the sucrose to the lactose is changed to 6:1 as a diluent. Thus, although either the original drug or CN 104771368 includes sucrose and lactose, neither of them describes the effect of sucrose on stability, nor has any technical implication.
The sucrose is coated by using a proper coating material and process, and the coated sucrose can be isolated from the bulk drugs so as to achieve the purpose of improving the stability of cefpodoxime proxetil particles. Specifically, the method comprises the following steps: according to the preparation method, sucrose is firstly subjected to film coating by using hydroxypropyl cellulose, and the prepared sucrose coated particles are subjected to wet granulation with raw material medicines and other auxiliary materials, wherein the cefpodoxime proxetil and the coated sucrose are not in direct contact in the production process of wet granulation and the storage period of the particles, so that the purpose of improving the stability of the cefpodoxime proxetil particles is achieved.
