title: Dissolution kinetics evaluation of controlled-release tablets containing propranolol hydrochloride.
abstract: In the present research, controlled-release propranolol hydrochloride tablets were prepared for twice-daily administration, allowing more uniform plasmatic levels of the drug. Pharmaceutical formulations were prepared with hydrophobic Eudragit RSPO. The physical properties of the tablets were determined. Dissolution tests were performed in capsules containing the raw material using the following dissolution media: (A) distilled water, (B) simulated gastric juice without enzymes, and (C) simulated enteric juice without enzymes. A dissolution test was also performed for simulated samples (tablets) using distilled water as the dissolution medium.
