The patient is 59 years old and was admitted to the local provincial hospital on January 22 for coughing and sputum, and was diagnosed with AML-M2a on January 30. The attending doctor has not agreed to chemotherapy because of the infection, and after the cough and temperature improved, she returned to the local county hospital on March 14, and that night her coughing sputum changed from mucous to foamy sputum, and her cough was slightly severe, and she is now receiving ceftizole. How to use it? Or is there any other oral antifungal drug? Itraconazole and fluconazole are the same class of drugs, the combination cannot increase the efficacy and may increase the side effects, it is recommended not to combine the two drugs. I don’t know what kind of fungus is infected, but Aspergillus is the most common type of lung infection, so we suggest using amphotericin B, or voriconazole or Coxacea, etc. Of course, itraconazole injection can also be used.
