Used primarily as an antibacterial agent, this compound is effective in treating urinary tract infections caused by susceptible strains of bacteria such as Escherichia coli and Proteus species. It functions by inhibiting bacterial DNA gyrase, an enzyme essential for DNA replication, transcription, and repair, thereby preventing the growth and spread of bacteria. Due to its pharmacokinetic profile, it achieves high concentrations in urine, making it particularly suitable for targeting infections in the urinary system. While largely superseded by newer antibiotics, it was historically valued for its oral bioavailability and relatively low incidence of side effects when used appropriately.
