FORMULATION AND EVALUATION OF SUSTAINED RELEASE PELLETS OF TRAMADOL HYDROCHLORIDE
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2013, Vol 4, Issue 2
Abstract
The aim of the present research is to develop and evaluate a better sustained release multiple unit pellets (MUP) formulation of Tramadol hydrochloride. Dissolution and diffusion controlled systems have classically been of primary importance in oral delivery of medication because of their relative ease of production and cost compared with other methods of sustained or controlled delivery. Most of these systems are solids, although a few liquids and suspension have been recently introduced. The present work aimed at developing SR pellets of Tramadol HCl by Wurster process. FTIR studies showed no unacceptable extra peaks which confirm the absence of chemical interaction between the drug and polymer. Angle of repose, tapped density, bulk density values for the formulations were within the range which indicates that pellets prepared by Wurster process were satisfactory for further studies. The percentage drug content of Tramadol was determined by extraction with methanol and analyzed by using UV-visible spectrophotometer at 271nm.
