A Glance at the Literature review on Buccal films

The present article concentrates on the Buccal film. It is a buccoadhesive drug delivery system that enhances the safety, efficacy, and stability of active pharmaceutical ingredients. The buccal film is a novel technology due to its better option to optimize therapeutic efficacy. This drug delivery system is suitable for drugs that pass through high first-pass metabolism and are used for enhancing bioavailability. The buccal film can be formulated as a solvent casting, semi-solid casting, hot-melt extrusion, solid dispersion, or rolling method. Among them, the solvent casting method is mostly adopted. The buccal films are evaluated for mechanical properties viz., Organoleptic assessment, thickness, dryness, tack test, tensile strength, percent elongation, folding endurance, swelling assets, surface pH, contact angle, transparency, uniformity in drug content, disintegration, and in-vitro dissolution tests. The article gave a handful of literature on past work done on buccal films. This article helps with quick references to the earlier attempts so far made on buccal films.
