Development and Evaluation of floating Alginate beads of Tramadol Hydrochloride
The objective of current research work was to develop gastro-retentive floating alginate beads of tramadol hydrochloride. The beads were formulated using different concentration of hydrophilic polymer HPMC K15M and HPMC K100M, along with an effervescent agent such as calcium bicarbonate. Preformulation compatibility studies indicate that there is no interaction between the excipient and the drug. Total seven batches were prepared and floating beads ware subjected for evaluation of flow properties. All the parameter was found to be within the limit showing good flow property.
