The ingredients of cephalosporin suspensions are mainly cephalosporin antibiotics, whose main function is anti-inflammatory and bactericidal. Patients with respiratory tract infections, urinary tract infections, and biliary tract infections can consider actively choosing second- or third-generation cephalosporin antibiotics for oral treatment. If the effect of oral treatment is not good for more than three days, or if the patient’s fever persists, intravenous infusion of cephalosporins should be actively considered for treatment. Generally, for biliary tract infections, patients can consider intravenous infusion of ceftriaxone, and tinidazole and other drugs for active anti-inflammatory treatment. If the patient has a pulmonary infection, change the sensitive antibiotics for active anti-inflammatory treatment based on the results of sputum culture. If the patient is due to urinary tract infection, urine culture can also be done if necessary to see the type of bacteria and drug sensitivity test of the patient’s urinary tract infection, and then select a sensitive antibiotic for anti-inflammatory treatment according to the drug sensitivity test. Generally, in experience, patients with urinary tract infections who are over 18 years old are preferred to levoxylated antibiotics, as well as ciprofloxacin and other drugs for active oral treatment.
