Hollow fibers as an oral sustained-release delivery system using propranolol hydrochloride.

Abstract:

:Fibers were spun by the downward configuration of the wet spinning technique. This configuration is capable of encapsulating nonspherical and/or coarse particles. We examined encapsulation of propranolol hydrochloride and the ability of the fibers to act as a sustained-release delivery system for propranolol hydrochloride as a model drug. The U.S.P. basket dissolution method was used to evaluate the in vitro drug release kinetics and the effect of the aspect ratio (length/diameter) on drug release. For in vivo evaluation, selected fibers were administered to dogs in gelatin capsules. The results of these in vitro and in vivo studies were compared to those obtained with a marketed sustained-release propranolol product (Inderal LA). The fiber delivery system provided a sustained-release profile of plasma propranolol concentrations similar to that observed with Inderal LA.
