that is often made with hydrophilic polymers and allows for fast disintegration when exposed to saliva. Oral disintegrating tablets and oral disintegrating films are two typical oral disintegrating medicine administration strategies. These systems were developed in the late 1970s as an alternative to standard dosage forms such as quickdissolving tablets and capsules for elderly and paediatric patients who had difficulty swallowing traditional dosage forms [45].

Orodispersible films, on the other hand, are flexible while remaining resistant to mechanical stresses. While lyophilization is a standard method for creating oral disintegrating tablets, orodispersible films are made using a technology similar to that used to make transdermal patches, which is less costly than lyophilization. Orodispersible films are preferable to liquid dosage forms such as drops or syrups because they allow for precise dosage. A quick beginning of effect might be obtained since the medication is delivered into the oral cavity in seconds. Some medications can bypass first-pass metabolism if they are absorbed through the oral mucosa, which may boost bioavailability. To ensure a strong production and packaging process as well as ease of handling and administration, an ideal orally disintegrating film must be thin and flexible, yet sturdy. The films must be transportable, non-sticky, and maintain a level shape without rolling up. They should have a nice taste and a comfortable tongue feel. The time it takes for something to disintegrate should be as quick as feasible. Because of the inverse link between mechanical qualities and disintegration time, meeting all of these parameters is difficult [46].
