Enhanced therapeutic efficacy of a novel self-micellizing nanoformulation-loading fisetin against acetaminophen-induced liver injury

Aim: To evaluate the feasibility of using dipotassium glycyrrhizinate (DG) as a nanocarrier-loading fisetin (FIT) with strengthened treatment efficacies against liver injury induced by acetaminophen overdose. Methods: DG–FIT was prepared, and its efficacy against liver injury induced by acetaminophen overdose was evaluated. Results: DG–FIT was successfully fabricated with excellent physicochemical properties. DG–FIT could be easily dissolved in water to form a clear micelle solution with high FIT encapsulation efficiency. FIT in DG–FIT exhibited a dramatically improved aqueous solubility. DG–FIT improved intestinal permeation. Regarding in vivo efficacies, DG–FIT exhibited significant effect against acetaminophen overdose by suppressing oxidative stress and proinflammatory cytokines involved. Conclusion: DG–FIT formulation possibly represents a promising method for strengthening the efficacy of FIT against acetaminophen-induced liver injury.
