Levofloxacin hydrochloride tablets

The invention discloses levofloxacin hydrochloride tablets which comprise an active ingredient levofloxacin hydrochloride and medicinal auxiliary materials, wherein the medicinal auxiliary materials comprise a filling agent, a disintegrating agent and a lubricating agent. In the large-scale production of tablets, magnesium stearate generally serves as the lubricating agent, however, because magnesium ion is extremely easily subjected to complexation with levofloxacin or salts thereof, the activity of the medicine is reduced, absorption of gastrointestinal tract on the medicine is interfered, and levofloxacin hydrochloride is unsuitable to be compatible with magnesium stearate. According to the research, when other conventional lubricating agents are used for large-scale preparation in the conventional technology, tests show that the conditions such as severe sticking, bonding, bouncing and low core friability occur in the process of tabletting levofloxacin hydrochloride exist. According to the research in the invention, the lubricating agent adopts talc powder and stearic acid which are added according to a specific compatibility ratio, the lubricating agent has excellent quality controllability in the large-scale production process of the levofloxacin hydrochloride tablets through tests, and the prepared levofloxacin hydrochloride tablets have high safety and effectiveness.
