ethanol–polyethylene glycol 600, and polyethylene glycol 600–water–ethanol mixtures at 25
C are reported. The solubilities of drugs in the presence of ethanol and polyethylene glycol
600 were increased. The Jouyban–Acree model was used to fit the solubility data of each
drug in the binary mixtures in which the overall mean relative deviations (OMRDs) for
acetaminophen and ibuprofen were 2.9% and 4.3%, respectively. The OMRDs for ternary …
