Anti-infective drug cefadroxil crystal compound and composition thereof

The invention belongs to the technical field of medicine, and discloses an anti-infective drug cefadroxil crystal compound and a composition thereof. The structural formula of the cefadroxil crystal compound is shown as the formula (I), the crystal compound is measured through a powder X-ray diffraction measuring method, and an X-ray powder diffraction pattern represented by the diffraction angle of 2 theta +/-0.2 degree is shown as the figure 1. The crystal compound is high in purity, low in impurity content, high in stability, not prone to moisture absorption and high in fluidity, and the solubility is greatly improved. The crystal compound can be directly subpackaged to prepare a capsule agent without adding an auxiliary, and the prepared capsule agent is high in dissolution rate, low in impurity content and high in stability.
