Abstract

The invention belongs to the technical field of medicines, and relates to prulifloxacin tablets and a preparation process thereof. The prulifloxacin tablet contains an active component prulifloxacin or a pharmaceutical salt thereof, as well as a carbonate alkaline substance and pharmaceutically acceptable additives. The prulifloxacin tablets can be obtained by direct power tabletting or wet method granulation tabletting, and adopt a thin-film coating mode. In the prulifloxacin tablets, the medicament stability is greatly improved, the solubility of the medicament is increased, and the bitter taste of the medicament can be effectively covered.

Description

technical field [0001] The invention belongs to the field of pharmacy and relates to a prulifloxacin tablet and a preparation process thereof. Background technique [0002] Infectious disease is the most common clinical disease, involving almost all clinical specialties, and it is also one of the most common causes of patient death. According to the report of the World Health Organization in 1997, the number of deaths from infectious diseases was as high as 33.3% of the total number of deaths from various causes. [0003] Anti-infective drugs are a powerful weapon for human beings to fight against infectious diseases. They are the largest in number, most in variety, and fastest growing, and the market demand for drugs in this area has always been very strong. According to statistics, the sales of anti-infective drugs account for the world's drug sales, second only to cardiovascular drugs. In my country, anti-infective drugs account for the market share of the entire drug s...
