The initiation of PANoptosis relies on the assembly and activation of the PANoptosome, a process that has been closely linked to the onset and progression of multiple disorders, including inflammatory and neurodegenerative diseases, cancer, and pulmonary conditions. However, the contribution of PANoptosis to drug-induced liver injury (DILI) has not been thoroughly evaluated. DILI is a frequently encountered clinical adverse drug reaction, and its development is strongly associated with hepatocyte death. Therefore, this review aims to summarize the molecular mechanisms underlying PANoptosis and the assembly of the PANoptosome complex, elucidate the interactions among apoptosis, necroptosis, and pyroptosis, and assess the potential involvement of PANoptosis in DILI. Furthermore, investigating natural products that inhibit PANoptosome assembly or target key regulators such as ZBP1, AIM2, and NLRP3 to modulate PANoptosis may offer promising therapeutic opportunities for the management of DILI.Keywords: drug-induced liver injury, PANoptosis, PANoptosome, therapeutic targets
