2. Known history of immune deficiency disease or receive immunocompromising treatment;

3. Severe cardiovascular and cerebrovascular diseases with clinical significance and unstable condition or uncontrolled;

4. Known or suspected central nervous system disorder or other factors that may predispose to seizures or lower the seizures onset threshold;

5. Presence of any known or suspected disease or condition that, in the opinion of the Investigator, may confound the assessment of efficacy;

6. Uncomplicated lower urinary tract infection;

7. Suspected or confirmed urinary tract symptoms caused by acute/chronic prostatitis, orchitis, epididymitis or sexually transmitted diseases as determined by medical history and/or physical examination;

8. Patients received cancer treatment within 4 weeks before randomization or planned treatment during the study period;

9. Systemic antimicrobial therapy other than the investigational drug need to be used during the study period, with the exception of topical or single oral dose of antifungal treatment

10. Urinary tract surgery prior to 7 days before randomization or surgery planned during the study period;

11. Indwelling catheter or urinary apparatus, the researchers determine drug treatment period cannot be removed;

12. Receipt of potentially effective systemic antibacterial therapy for a continuous duration of ≥24 hours during the previous 48 hours prior to the randomization;

15. Impairment of renal function with estimated glomerular filtration rate or Creatinine Clearance <15 mL/min ;

16. Laboratory abnormalities in baseline specimens obtained at screening;

17. A QTcF interval prolongation at screening or abnormalities with clinical significance and may cause obvious safety risk to the subjects;
