Abstract

The invention provides sodium houttuyfonate dispersible tablets. The sodium houttuyfonate dispersible tablets are prepared by uniformly mixing coating micro-capsules of sodium houttuyfonate with other pharmaceutically acceptable adjuvant materials prior to tableting.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a houttuyfonate sodium dispersible tablet and a preparation method thereof. Background technique [0002] Houttuyfonate Sodium, also known as Houttuyniatin, is a sodium bisulfite adduct of decanoyl acetaldehyde, which is the first effective antibacterial and anti-inflammatory drug used in clinical practice in my country (Zheng Junmin et al. Research on crystal form and bioavailability, Journal of Shenyang Pharmaceutical University, 1981, total 13). Houttuyfotin sodium has obvious inhibitory effect on catarrhal bacteria, influenza bacillus, pneumococcus, and staphylococcus aureus, and has obvious effects of antagonizing inflammatory exudation and tissue edema in the early stage of inflammation, and inhibiting inflammatory pain response, especially for Treatment of cervical erosion. [0003] However, houttuyfonate sodium is a white or off-white need...
