Agaricoglyceride A (AGA), showed strong activities against neurolysin. The objectives of this study was to prepare solid self-emulsifying drug delivery system (sSEDDS) by spray drying the SEDDS (liquid system) using Aerosil 200 as the inert solid carrier, and to evaluate the enhanced bioavailability (BA) of AGA from sSEDDS. The AGA formulated in the sSEDDS was quickly and completely dissolved within 20min, both in 0.1N HCl and phosphate buffer pH 6.8 dissolution media, whereas AGA powder was significantly less dissoluble. Meanwhile, the sSEDDS formulation was stable for at least 90days at room temperature. the plasma levels of AGA in the solid SEDDS group at the dose level (15mg/kg) remained detectable for up to 1.5 h after the oral dose. After oral administration to rats, a significant increase (P<0.0001) in the Cpmax and AUC0→24 h were observed in the sSEDDS group when compared with the AGA powder group. Furthermore, AGA-loaded sSEDDS exerted significant antinociceptive properties and alleviated pain insults in mice. The results suggest that the sSEDDS could be considered and further evaluated for the oral delivery of lipophilic poorly soluble drugs for which an oral route of administration is desirable.
