Interaction between phenylephrine hydrochloride and polyethylene glycol 400.
Evidence of complexing tendency of the water-soluble polymer polyethylene glycol 400 (PEG 400) and phenylephrine hydrochloride was supported by the equilibrium dialysis method. The influence of polymer concentration, ionic concentration, and hydrogen ion concentration of the systems on the interaction was investigated. Attempts to separate the complex by using paper chromatographic techniques have also been made.
