title: Comparative study of propranolol hydrochloride release from matrix tablets with KollidonSR or hydroxy propyl methyl cellulose.
abstract: The release of propranolol hydrochloride from matrix tablets with hydroxy propyl methyl cellulose (HPMC K15M) or KollidonSR at different concentrations was investigated with a view to developing twice daily sustained release dosage form. A hydrophilic matrix-based tablet using different concentrations of HPMC K15M or KollidonSR was developed using direct compression technique to contain 80 mg of propranolol hydrochloride. The resulting matrix tablets prepared with HPMC K15M or KollidonSR fulfilled all the official requirements of tablet dosage forms. Formulations were evaluated for the release of propranolol hydrochloride over a period of 12 h in pH 6.8 phosphate buffer using USP type II dissolution apparatus. Propranolol hydrochloride and pure KollidonSR or HPMC K15M compatibility interactions was investigated by using Fourier-transform infrared (FTIR) spectroscopy and differential scanning calorimetry (DSC). FTIR spectroscopic and DSC studies revealed that there was no well defined chemical interaction between propranolol hydrochloride with KollidonSR or HPMC K15M. Tablets were exposed to 40 degrees C/75% of RH in open disc for stability. The in vitro drug release study revealed that HPMC K15 at a concentration of 40% of the dosage form weight was able to control the release of propranolol hydrochloride for 12 h, exhibit non-Fickian diffusion with first-order release kinetics where as at 40% KollidonSR same dosage forms show zero-order release kinetics. In conclusion, the in vitro release profile and the mathematical models indicate that release of propranolol hydrochloride can be effectively controlled from a single tablet using HPMC K15M or KollidonSR matrix system.
