Abstract

Objective: The aim of this study was to develop a novel gastro retentive oral floating in situ gelling system for controlled release of Meloxicam. Meloxicam is an NSAID that inhibits cyclooxygenase (COX) synthesis and has analgesic and antipyretic effects.


Methods: Four polymer based floating in situ gelling systems of Meloxicam were prepared by dissolving varying concentrations of different ingredients including sodium alginate, HPMC K100M, calcium carbonate, sodium citrate. The prepared gels were characterized for solution viscosity, pH, gelling capacity, floating lag time, floating duration and in-vitro release study.


Results: The formulations possessed satisfactory pH value ranging from 7.25±0.09 to 8.12±0.49. All the formulations showed instant gelation maintaining integrity for at least 12 h. Maximum drug release was shown by formulations of batch G1 (94.38%).


Conclusion: The study demonstrated that a stomach specific in-situ gel of Meloxicam could be prepared using the floating mechanism to increase the residence time of the drug in the stomach and improve bioavailability and thus improve patient compliance.

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.
