Polymers used in mouth dissolving film: A review

The oral route is one of the most important routes for local and systemic drug delivery, as it has a large surface, high permeability, and rich blood supply. Mouth dissolving films, are now becoming more popular than fast-dissolving tablets. The films are designed to disintegrate quickly when they come into touch with a surface that contains water, such the tongue. This allows the consumer to consume the product without the use of water. It can boost patient compliance and provide you a marketing advantage. The polymer used in mouth dissolving films is crucial to their quick dissolution and disintegration. The polymer must be non-toxic, non-irritating, flavorless, and simple to use. Natural and synthetic polymers are the two types of polymers that are employed. Natural polymers used in formulation of film include chitosan, gaur gum, xanthan gum, soy polysaccharide, gellan gum, locust bean gum, maltodextrin, and rosin. Hydroxypropyl cellulose, polyvinyl pyrrolidone, Hydroxypropyl Methylcellulose, Polyethylene Oxide, and Polyvinyl Alcohol are synthetic polymers that are frequently used to make films. The current overview gives a description of the numerous polymers that are utilized to make films that dissolve in the mouth.
