Objective: To optimize formulation of andrographolide self-microemulsifying preparation and evaluate its quality. Method: Type and dosage range of excipients was selected by solubility test
prescription compatibility comparison test and drawing ternary phase diagram
with appearance
particle size
zeta potential
self-emulsifying time and preparation stability of the formed emulsion as indexes
central composite design-response surface methodology was used to optimize self-microemulsion prescription and evaluate its quality. Result: Optimum prescription of this preparation was as following:mtween-80:methyl oleate:mglycerol=50:26:26
particle size 39.5 nm
zeta potential -15.18 mV
self-emulsifying time 40.53 s. Conclusion: These acquired androgra-pholide self-microemulsion preparation was clear and transparent with good physical stability.
