Abstract

Objective Solid dispersions of daidzein (DZ) were prepared using tween-80 as the surfactant to improve its
dissolution and solubility. Methods Using tween-80 as the surfactant and polyethylene glycol (PEG)-10000 as the
carrier, solid dispersions of DZ were prepared by solvent method. Infrared spectroscopy (IR) and X-ray diffraction
spectroscopy were applied to determine the status of DZ in carriers. Results When appropriate amount of Tween-80
was added into the solid dispersion, the dissolution of DZ could be improved obviously. The data of IR showed the
absence of well-defined drug-polymer interactions. The data of X-ray diffraction showed that the drug might exist in
the form of amorphism or molecule in solid dispersions. Conclusion Appropriate amount of Tween-80 could
increase the dissolution rate of DZ.
