A novel self-nanomicellizing system of empagliflozin for oral treatment of acute pancreatitis: An experimental study
Abstract
Acute pancreatitis (AP) is a severe inflammatory disorder hampered by a lack of effective drugs in its clinical practice. Empagliflozin (EMP) exhibits potential effects against AP but is limited by poor water-solubility and low bioavailability. Herein, a novel self-nanomicellizing formulation of EMP with phytochemical rebaudioside A (RA) as the nanocarrier (RA-EMP) was fabricated to address these issues. RA-EMP powder could be simply prepared and exhibited excellent storage stability, dramatically improved EMP's apparent solubility, and instantly self-assembled into micelles with high EMP encapsulation efficiency in water. In vivo experimental studies showed that RA-EMP exhibited significantly enhanced oral bioavailability of EMP and dramatically improved therapeutic efficacy against AP. The mechanisms through suppressing the effects of oxidative stress and proinflammatory cytokines were involved in this therapeutic effect. The results demonstrated that RA-EMP could serve as a promising way to enhance the oral bioavailability and strengthen the potential therapeutic efficacy of EMP against AP.
