The effect of different polymers on the solubility, permeability and distribution of poor soluble 1,2,4-thiadiazole derivative

Solubility and permeability are the main parameters determining the bioavailability of drugs. In this study the increased solubility of novel 1,2,4-thiadiazole derivative (TDZ) proposed for the prevention and treatment of Alzheimer's disease was achieved in the solutions of polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), and pluronic F127 (F127). It was found that solubilizing power of polymers follows the order F127 > PVP > PEG. The...
