| Summary: | This study investigates using of high molecular weight hydrophilic polymers,
hypromellose and hydroxypropylcellulose, for the preparation of sustained
release matrix tablets containing high dose, highly soluble drug, tramadol
HCl. Proportion of polymer, type of insoluble filler, proportion of tramadol
HCl, amount of drug in the tablet and compression pressure were recognized as
critical formulation and process parameters and their influence on drug
release and tablet mechanical properties was evaluated. Tensile strength was
used as indicator of mechanical properties of the tablets. Experiments were
performed with utilization of compaction simulator as a device which
simulates compaction profiles of large scale rotary tablet presses. In
formulations with both polymers proportion of tramadol HCl was the most
critical formulation parameter wherein increasing of the tramadol HCl
proportion increased its release rate in early stages of drug release.
Regarding the tablet mechanical characteristics, the influence of the filler
type has the most pronounced effect in formulations with both polymers.
Higher tensile strengths were obtained with Avicel PH 102 as filler in
formulations with both HPMC and HPC. [Projekat Ministarstva nauke Republike
