DEVELOPMENT AND CHARACTERIZATION OF DIRECT COMPRESSED MATRIX MINI TABLETS OF NAPROXEN SODIUM
The present study was carried out to formulate and evaluate multiparticulate system containing mini-tablets of Naproxen sodium. Naproxen is a nonsteroidal anti-inflammatory drug (NSAIDs) with analgesic and antipyretic properties. Pre-formulation studies showed good ﬂow and compaction capacity, leading to the production of high quality mini-tablets. The drug-excipients compatibility studies were performed using FTIR techniques. Ten different matrix mini tablets were manufactured by direct compression using various polymers like HPMC K4M, PVP K30 in different ratio. The prepared mini tablets were subjected to pre and post compressional parameters and the values were within the prescribed limits. The in-vitro performance showed the desired biphasic behaviour. Drug release from matrix mini tablets was sustained over a period of 10 hours and release rate. Study concludes that Naproxen sodium can be successfully released in a controlled manner by the use of developed matrix mini-tablets.
