ABSTRACT
@#Non-alcoholic fatty liver disease (NAFLD) is a series of chronic liver diseases strongly associated with the metabolic disorder with an increasing rate of worldwide prevalence.Due to its complicated pathogenesis, only Saroglitazar has been approved by Indian Drug Controller General (DCGI) as a PPAR-α/γ dual agonist to treat non-cirrhotic non-alcoholic steatohepatitis.Combination therapy, which can target same or different signaling pathways of NAFLD pathogenesis, has been developed to achieve synergistic therapeutic efficacy.Currently, small-molecule drug combination, RNAi combination therapy, and chemogene therapy are proposed as promising strategies in NAFLD treatment.In addition, designing a smart, safe and effective drug delivery system is key to realizing the druggability, clinical translation and industrialization of small molecule drugs and gene drugs.This review summarizes the research status and delivery system of small-molecule drug combination, RNAi combination therapy, and chemogene therapy, in the hope of providing some novel insight for the treatment of NAFLD.
