Indication: 1. Typhoid and other Salmonella infections: It is the drug of choice for typhoid and paratyphoid caused by sensitive strains. This product is generally not suitable for gastroenteritis caused by Salmonella infection. It can still be used if the condition is serious and there is a possibility of septicemia. In adult typhoid and paratyphoid Salmonella infections, fluoroquinolones are the first choice (pregnant women and children should not use this type of drug). 2. This product can be used as one of the drugs for ampicillin-resistant Haemophilus influenzae type B meningitis or Streptococcus pneumoniae, Neisseria meningitidis meningitis, and sensitive Gram-negative bacillus meningitis in patients allergic to penicillin. 3. Brain abscesses, especially those caused by ear, are often mixed infections of aerobic and anaerobic bacteria. 4. Severe anaerobic infections, such as infections caused by Bacteroides fragilis, are especially suitable for those with lesions involving the central nervous system. It can be used in combination with aminoglycoside antibiotics to treat abdominal and pelvic infections to control the simultaneous presence of aerobic and anaerobic infections. 5. When there is no other low-toxic antibiotic alternative, it can be used to treat various serious infections caused by sensitive bacteria, such as sepsis and lung infections caused by Haemophilus influenzae, Salmonella and other Gram-negative bacteria, often in combination with aminoglycosides; 6. For Rickettsial infections, it can be used to treat Q fever, Rocky Mountain spotted fever, endemic typhus, etc.
