The main ingredient of flupivacate capsules is norfloxacin, a fluoroquinolone antibacterial drug with broad-spectrum antibacterial effect, especially the highest antibacterial activity against aerobic gram-negative bacilli. Flupivacate capsules are indicated for urinary tract infections, gonorrhea, prostatitis, intestinal infections and typhoid fever and other Salmonella infections caused by sensitive bacteria. Since serious adverse reactions have occurred with fluoroquinolones, also including norfloxacin capsules, and because simple urinary tract infections are also self-limiting for some patients, norfloxacin capsules should be used only when no other medications are available. For acute simple lower urinary tract infections caused by Escherichia coli, Klebsiella pneumoniae and Aspergillus chimaera, the course of medication is three days. For other pathogenic bacteria caused by simple urinary tract infection course is 7-10 days, for complex urinary tract infection course is 10-21 days, for acute and chronic prostatitis course is 28 days, intestinal infection course is 5-7 days, for Salmonella typhi infection course is 14-21 days.
