ABSTRACT
A new method for determining solubility lines of drugs in polymers, based on low-frequency Raman spectroscopy measurements, is described and the results obtained by this method are compared with those obtained using a more classical method based on differential scanning calorimetry investigations. This method was applied to the paracetamol/PVP system using molecular and crystalline dispersions (MCD) rather than usual physical mixtures to reach faster the equilibrium saturated states and make the determination of the solubility line more rapid.
