In the case of chronic illnesses, fast-dissolving drug delivery systems were developed as an oral medication administration alternative to traditional dose forms. For masking the taste of unpleasant drugs and enhancing patient compliance, fast-dissolving films are now recommended over traditional tablets and capsules. Fast dissolving films consist of a very thin oral strip that dissolves in less than one minute when placed on the tongue. Customers have responded positively to dissolvable oral thin films in the form of breath strips, which have been on the market for a few years and are used to administer vitamins, vaccines and other medicinal products. In fact, the review goes through the various production methods for film preparation. The current review summarizes the majority of recent patents on fast-dissolving films. A brief analysis of the several factors considered to analyze such films has been carried out. These fast-dissolving films are better to other oral traditional dose forms in terms of delivering drugs and attaining faster therapeutic blood levels in the case of chronic diseases.
