Problems solved by technology
Levofloxacin hydrochloride is a BCSI compound, but levofloxacin hydrochloride is easy to aggregate, and the aggregated levofloxacin hydrochloride has poor solubility. The poor solubility caused by the aggregation of levofloxacin hydrochloride is the key factor affecting the difference in clinical efficacy
The existing technology adopts various methods to solve the technical obstacle of easy aggregation of levofloxacin hydrochloride, but none of them can solve the tendency of easy aggregation and dissolution rate decline of levofloxacin hydrochloride during long-term storage.
[0007] 104288112A discloses a levofloxacin hydrochloride tablet, which adopts talcum powder and stearic acid to add in a specific compatibility ratio, and shows excellent quality controllability in the large-scale production test of levofloxacin hydrochloride tablet, the prepared levofloxacin hydrochloride tablet It has good safety and effectiveness, but it fails to solve the tendency of levofloxacin hydrochloride tablets to aggregate and decrease in dissolution rate during long-term storage

Abstract
The invention relates to a levofloxacin hydrochloride tablet, belongs to the new technological field of medicine manufacturing and in particular relates to the levofloxacin hydrochloride tablet and a preparation method thereof. The levofloxacin hydrochloride tablet takes levofloxacin hydrochloride as a main ingredient and is formed by carrying out direct compression on a levofloxacin hydrochloride composition and auxiliary materials, wherein the levofloxacin hydrochloride composition is prepared by adopting the method comprising the following steps: uniformly mixing levofloxacin hydrochloride with micropowder silica gel, and carrying out dry granulation, and the weight ratio of levofloxacin hydrochloride to the micropowder silica gel is 10:(1-2). The levofloxacin hydrochloride tablet provided by the invention has the advantages that descending trend of in vitro dissolution of the levofloxacin hydrochloride tablet is solved, pharmaceutical effect is improved, and more ideal treatment effect is realized.
