FORMULATION AND EVALUATION OF FAST DISSOLVING TABLETS OF ANTIEPILEPTIC DRUG
Objective: The objective of the present study was to prepare and evaluate the mouth dissolving tablet of lacosamide using super disintegrants like Guar Gum, and other excipients like microcrystalline cellulose and mannitol in different concentrations by direct compression method. Lacosamide has been shown to be an effective antiepileptic agent appropriate for epilepsy patients.
Methods: The mouth dissolving tablets were prepared by a single punch machine using a powder blend of super disintegrants and lacosamide. Post-compression parameters like hardness, weight variation, friability, in-vitro dispersion, drug content uniformity, and in-vitro drug release studies were carried out for all formulations.
Results: All formulations results were within official limits. Fast disintegration time obtained between 35sec. and 128 sec, was within the official limit. Different drug release kinetic models were applied for selecting batches for stability studies. These showed that there was no significant change in residual drug content in mouth dissolving tablets.
Conclusion: By the in-vitro disintegration, it is concluded that formulation prepared by Guar Gum (10%) showed faster disintegration time than that of MCC. This indicates that the use of super disintegrants increases the release of drug from the formulation. Therefore, it can be concluded that such mouth dissolving tablets are suitable delivery systems for lacosamide.

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.
