Acute appendicitis is among the most common cause of acute abdominal pain. In patients with complicated acute appendicitis, postoperative, broad-spectrum antibiotics are always recommended. Metronidazole, a member of the nitroimidazole drug class, is included in the regimens recommended for improving anaerobic bacteria coverage. The sideeffects of metronidazole include a metallic taste, nausea, transient neutropenia, and peripheral neuropathy. Antimicrobial resistance to metronidazole has emerged after several decades of worldwide use of the drug. Morinidazole, a National Class I Antimicrobial, is a new type of third-generation nitroimidazole antimicrobial that is used for treating amoebiasis, trichomoniasis, and anaerobic bacterial infections, and which exhibits greater activity and less toxicity than metronidazole.~Morinidazole and Sodium Chloride Injection used in pelvic inflammatory disease or appendicitis cases had been approved by CFDA in 2014. This phase 4 study is to assess the efficacy, safety, tissue distribution of target organ and Population Pharmacokinetic (PPK) of morinidazole in patients with suppurative or gangrenous appendicitis.
