Abstract: AIM: To evaluate relationship between dosing schedules and safety of voriconazole by analyzing the monitoring results of voriconazole in patients with liver dysfunction, and to provide reference for the clinical individualized medication. METHODS: The blood concentration and safety information of voriconazole in patients with liver dysfunction was searched in PubMed, Cochrane Library, Wanfang, Weipu, and Chinese Journal Full-text Database from the establishment of the databases to December 2019, the dosing schedule and safety range of voriconazole for patients with liver dysfunction was analyzed. RESULTS: A total of 10 literatures were selected, 5 of which were multi-sample retrospective studies and 1 of which was prospective study, and the remaining 4 were case reports. In Child-Pugh grade C liver dysfunction, a maintenance dose of 100 mg q12h is more secure. The incidence of adverse reactions of voriconazole is generally within 7 days. When the target trough concentration is less than 5 mg/L or 5.3 mg/L, the incidence of adverse reactions is still high. The main adverse reactions include neurotoxicity, hallucinations, visual disturbances, gastrointestinal reactions and rash. CONCLUSION: The dose of voriconazole in patients with liver dysfunction should be reduced, and the drug concentration should be monitored in a timely manner. It is recommended that on the basis of ensuring the efficacy, trough concentration can be further reduced to reduce the occurrence of adverse reactions in patients with liver dysfunction.
