The fineness of the dispersed particles causes them to dissolve more quickly owing to their higher dissolution pressure and leads to an increased saturation solubility. In the melting method, drug entities must be unavoidably exposed to very high temperature, which is detrimental to heat-sensitive drugs; moreover, there is difficulty in pulverizing the congealed melts owing to their relatively soft nature.17 Although the solvent evaporation method can be carried out at relatively lower temperatures, a large amount of organic solvent should be used to solubilize both the drug and the polymers, which thus imposes problems of safety concerns, high costs, and residual solvent removal.22 The cogrinding method consumes a lot of energy, and the dispersion efficiency is quite low.20 Recently, the supercritical fluid (SCF) technique has been proposed as an alternative for formulating SDs with distinct features of operating at lower temperature to avoid heat decomposition, lower residual organic solvent, and one-step production of powders with better flowability.2224 In the SCF process, liquid carbon dioxide (CO2) is used as the antisolvent, which leads to the precipitation of the substrates initially dissolved in the organic solvent.22,25,26 Certain aspects of this technology can be found in the works of other groups.12,23,24 Meanwhile, some studies also reported the use of SCF technology to obtain nanoscale-level SD particles or drugpolymer aggregates to improve the solubility and oral bioavailability of ITZ.27,28.
