DEVELOPMENT AND CHARACTERIZATION OF MUCOADHESIVE PATCHES FOR BUCCAL DELIVERY OF PREGABALIN

Abstract

Objective: Pregabalin is a structural analogue of the inhibitory neurotransmitter γ-amino butyric acid (GABA) having short half-life (5-6 hrs) and is used in the management of epilepsy. The aim of this study was to prepare a buccal patch containing Pregabalin by the means of solvent casting method.


Methods: Six formulations were prepared using different ratio of polymers including HPMC K4M, Eudragit RL, and PVP K30. Franz diffusion cell with commercially available dialysis membrane was used for the in-vitro diffusion study of buccal patches for duration of 12 hrs. Kinetics and mechanism of drug release from all formulation was evaluated on the basis of zero order, first order, Hixon-Crowell, Higuchi equation and Peppas model.


Results: The thickness of formulated patches varied from 0.48±0.25 to 0.52±0.09 mm. The average weight of patch from each batch ranges from 0.25±0.42 to 0.38±0.09. Percentage drug release for the formulations F1, F2, F3, F4, F5 and F6 was found to be 45.32, 61.2, 76.43, 93.76, 82.48 and 55.62% respectively in a study of 12 hrs.


Conclusion: Study concludes that Pregabalin can be delivered in an efficient way in mucoadhesive patches form. Based on different parameters buccal patches of batch F4 (HPMC K4M and Eudragit RL 100) was found to an optimum formulation.

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.
