ABSTRACT
The aim of the present investigation is to, formulate and develop a novel oral monolithic, controlled
release tablet dosage form for Propranolol hydrochloride to provide steady state drug release over an
extended period of time. The drug candidate selected Propranolol hydrochloride was formulated as
controlled release matrix tablets which consisted of locast bean gum as polymer, electrolytes and
other diluents by wet granulation technique. Electrolytes such as sodium carbonate, magnesium
carbonate and calcium carbonate were added at various concentrations in various formulations, while
the drug to polymer concentrations was maintained at different ratios respectively. The tablets were
analyzed to determine their hardness, friability, dug content and in vitro release profile. The influence
of the proportion of the gum and electrolytes on the release rate of the drug from the tablets was
evaluated. The drug release rate was influenced by diffusion and swelling mechanisms exhibiting
non-Fickian transport. The findings indicated that the swelling and gel formation in the presence of
electrolytes within the hydrophilic matrices provided controlled drug delivery of drug from a simple
monolithic system. The DSC and FTIR studies indicated that there was no chemical interaction
between drug and excipients. Stability studies (40±2ºC/75±5%RH) for 3 months indicated that
Propranolol hydrochloride was stable in the matrix tablets.
