The physical and chemical properties of propranolol hydrochloride and anionic polymer complex were investigated using Fourier transform infrared spectroscopy FTIR and differential scanning calorimetry DSC. Click here to view all the property values for this datasheet as they were originally entered into MatWeb. To achieve these aims, yield, incorporation efficiency, particle size and the distribution of microspheres were determined, and the influence of the inner phase viscosities prepared with different polymer and polymer mixtures on particle size and the distribution of microspheres were evaluated.

Int J Pharm Oct 15; 1: Yakugaku Zasshi Jun; 6: The DSC profiles demonstrated that the characteristic peak of propranolol hydrochloride cannot be found in the heating curve of the complexes, indicating that complex is different in physicochemical properties from the physical mixture of drug-polymer.
