Enteritis can be divided into infectious enteritis and non-infectious enteritis, and there is a certain difference in medication. For infectious enteritis, the main treatment is based on antibiotic drugs such as roxithromycin and levofloxacin, etc. For non-infectious enteritis, it is necessary to take symptomatic treatment as the main treatment, and can also take immunomodulators, such as azathioprine, methotrexate and other treatments as the main treatment. 1. Infectious enteritis: mainly caused by germs and parasitic infections, patients can take roxithromycin, levofloxacin and other drugs according to the pathogen for treatment. If there is diarrhea and other symptoms, you can also apply montelukast for treatment. 2. Non-infectious enteritis: mainly due to improper diet, immune damage and abuse of antibiotics, patients can take azathioprine, methotrexate and other immunomodulators for treatment. Surgery can also be considered if complications arise from enteritis due to Crohn’s disease. Patients with different causes of the disease, the specific medication regimen, must follow the doctor’s instructions.
