Popis: In the present study, we prepared nattokinase-loaded self-double-emulsifying drug delivery system (SDEDDS) and investigated its preliminary pharmacodynamics. The type and concentration of oil phase, inner aqueous phase and emulsifier were screened to prepare optimum nattokinase-loaded SDEDDS. Next, the optimum formulations were characterized based on microstructure, volume-weighted mean droplet size, self-emulsifying rate, yield, storage stability, in vitro release and in vivo pharmacodynamics studies. The water/oil/water multiple emulsions exhibited typical multiple structure, with relatively small volume-weighted mean droplet size 6.0 ± 0.7 μm and high self-emulsifying ability (self-emulsifying time
