Moxifloxacin Hydrochloride, as the fourth-generation quinolone antibiotic, possesses broad-spectrum antibacterial activity, demonstrating potent antibacterial effects against various Gram-positive and Gram-negative bacteria. Its antibacterial mechanism primarily involves inhibiting the activity of bacterial DNA gyrase (topoisomerase II), thereby blocking bacterial DNA replication and transcription, and ultimately achieving a bactericidal effect.
