Commonly used antibiotics for urinary tract infections are penicillins, cephalosporins, quinolones, which need to be selected according to the cause of the disease in order to play a better therapeutic effect. Urinary tract infections are mainly divided into upper urinary tract infections and lower urinary tract infections, and the most common mode of infection is upward infection. The most common form of infection is the upstream infection. The pathogens that cause urinary tract infections are mainly gram-negative bacilli, and can also be caused by fungi or trichomonas vaginalis. Therefore, different types of antibiotics should be chosen for different pathogens in order to achieve the best therapeutic effect. For bacterial infections, you can choose cephalosporins (ceftazidime, cefuroxime, etc.), penicillins (amoxicillin, etc.) or quinolones (levofloxacin, norfloxacin, etc.). For fungal infections you need to choose antifungal drugs (fluconazole, itraconazole, etc.), and for trichomonas infections you need to choose antibiotics specifically designed to kill trichomonas (such as metronidazole, etc.). There are many types of antibiotics available for the treatment of urinary tract infections, and it is not possible to generalize the choice of one antibiotic for treatment, but to choose the antibiotic that is specific to the cause of the disease in order to achieve the best therapeutic effect. It is recommended that patients with symptoms of urinary tract infections seek medical attention as soon as possible, by a professional doctor according to the condition of the choice of drugs, do not blindly use their own medication.
