Abstract
Drug can cause almost all known types of acute, subacute, and chronic liver injuries. Drug-induced liver injury (DILI) is an important cause of unexplained liver injury in clinical practice. Correct diagnosis of DILI is challenging due to lack of specific diagnostic biomarkers, especially in patients with pre-existing liver disease and multiple concomitant drugs. A comprehensive understanding of the risk factors, clinical features, and prognosis of liver injury caused by different drugs will help physicians to recognize, diagnose, and manage it timely. Although the guideline was developed based on evidence-based medicine provided by the latest studies, there is limited high-quality evidence in the field of DILI. Therefore, this guideline should be interpreted with caution, and physicians should adopt an optimal diagnostic and therapeutic strategy for individual patients within the framework of the guideline.
