Objective:  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.

Methods: 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.

Results: 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.

Conclusion: Study concludes that Naproxen sodium can be successfully released in a controlled manner by the use of developed matrix mini-tablets.

Received 4 October 2018;   Revised 20 October; Accepted 6 November, Available online 15 November 2018

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
