Aqueous and pH dependent coacervation method for taste masking of paracetamol via amorphous solid dispersion formation.

ABSTRACT: Taste masking of paracetamol was achieved by preparing amorphous solid dispersion (ASD) using modified coacervation method. The method is based on dissolving the drug and polymeric carrier in water adjusted to certain pH level. Then, precipitation of ASD granules is performed by gradually changing pH level. Therefore, the chosen drug and polymer should obtain appropriate acidic or basic groups to enable pH-dependent solvation. Moreover, using solubility enhancing additives such as sodium lauryl sulphate (SLS) and low viscosity polyethylene glycol (PEG 400) found to be essential in aiding drug/polymer aqueous solvation which enhanced amorphization, hence taste masking and drug loading. Solid dispersion between Paracetamol and Eudragit E was formed and that proved by FT-IR, DSC, PXRD and SEM
