Self-nanoemulsifying drug-delivery systems improve oral absorption and antischistosomal activity of epiisopiloturine

Aim: To develop a self-nanoemulsifying drug-delivery system (SNEDDS) able to improve oral absorption of epiisopiloturine (EPI), and test the antischistosomal activity in a mice model. Results: SNEDDS had a nanoscopic size and was able to enhance EPI bioavailability after oral administration, and SNEDDS-EPI (40 mg.kg(-1)) improved the in vivo antischistosomal activity of EPI, demonstrating that SNEDDS was able to improve the pharmacokinetics of EPI, and to maintain the pharmacodynamic activity against Schistosoma mansoniin vivo. Conclusion: Taken together, these results indicate that SNEDDS-EPI is efficient in reducing worm burden in comparison to treatment with the free version of EPI. [GRAPHICS] .
