Abstract
CThe objective of the present study was to prepare solid self-nanoemulsifying drug delivery system (S-SNEDDS) containing Capryol-90 as oil phase for the delivery of Embelin, a poorly water soluble herbal active ingredient. Box-Behnken experimental design was employed to optimise the formulation variables, X1 (amount of oil; Capryol 90), X2 (amount of surfactant; Acrysol EL 135) and X3 (amount of co-surfactant; PEG 400). Systems were appraised for visual characteristics for self emulsifying time, globule size and drug release. Optimised liquid formulations were formulated into free flowing granules (S-SNEDDS) by adsorption on the porous materials like Aerosil 200 and Neusilin and thereby compressed into tablet. In vitro dissolution studies of SNEDDS revealed increased in the dissolution rate of the drug. FT-IR data revealed no physicochemical interaction between drug and excipients. Solid state characterization of S-SNEDDS by DSC and Powder XRD confirmed reduction in drug crystallinity which further supports the results of dissolution studies. TEM analysis exhibited spherical globules. Further, the accelerated stability studies for 6 months revealed that S-SNEDDS of Embelin are found to be stable without any significant change in physicochemical properties. Thus, the present studies demonstrated dissolution enhancement potential of porous carrier based S-SNEDDS for poorly water soluble herbal active ingredient, Embelin.
