ABSTRACT
OBJECTIVE: To evaluate the incidence of Ketoconazole associated hepatotoxicity and related factor. METHODS: Literature retrieval was conducted by using multi-databases for meta-analysis on Ketoconazole associated hepatotoxicity. The data were collected with a standardized form. Overall estimation of incidence of hepatotoxicity for specific study type was calculated by using a DerSimonian-Laird random-effects model owing to the substantial differences among the studies. RESULTS: Totally 204 eligible studies were included in the analysis. The incidence of Ketoconazole associated hepatotoxicity was 3.6%-4.2%. The dosage and duration specific subgroup analyses did not show any significant difference among groups, while the age specific subgroup analysis showed the incidence in children and people aged >60 years was 1.4% (95% CI: 0.5%-4.2%) and 3.2% (95% CI: 1.1%-8.7%) respectively. Additionally, the incidence of the hepatotoxicity was higher in people who had oral administration of ketoconazole beyond the provisions of the usage instructions, and the incidence was 5.7% (95% CI: 4.5%-7.2%). CONCLUSION: Ketoconazole associated hepatotoxicity was common. Off-label use might increase the risk of liver damage. Well-designed large sample studies are needed to identify the risk factors in future.
