Different methods for solid dispersions of ellagic acid [37].
| Method | Composition | Procedure |
|---|---|---|
| Spray-dried solid dispersion | Acetone : ethanol (1 : 4 v/v) solution, ellagic acid, polyvinylpyrrolidone (PVP), carboxymethyl cellulose acetate butyrate (CMCAB), hydroxypropyl methyl cellulose acetate succinate (HPMCAS) | Acetone : ethanol solution was used to dissolve mixtures of EA/polymer followed by spray drying of the resultant dispersion under operating conditions of 90°C inlet temperature, 57–60°C outlet temperature, 9 mL/min feed rate, and 350 L/h nitrogen flow. |
|
| ||
| Coprecipitated solid dispersion | Ellagic acid, tetrahydrofuran (THF), cellulose acetate adipate propionate (CAAdP) | A mixture of EA/CAAdP was dissolved in THF followed by dropwise addition of the solution in deionized water with stirring. |
|
| ||
| Solid dispersion by rotary evaporation | Ellagic acid (20 mg), PVP (90 mg), CAAdP (90 mg), acetonitrile : ethanol (1 : 1 v/v) solution (40 mL) | EA, PVP, and CAAdP were dissolved in acetonitrile : ethanol solution followed by concentrating the solution with rotary evaporation |
