The polymer is the film former and the main component on the formulation. The ideal polymer is one capable of producing smooth, thin films that are reproducible under routine coating conditions. The range of materials that can be used as film formers is very wide and covers materials that may be natural, synthetic or semi-synthetic.

The film-coating formulation combines four key ingredients: A film-forming polymer, which provides the mechanical strength of the film. The most widely used polymers in non-functional film coating are cellulose derivatives such as hypromellose. Plasticizers, used to improve the flexibility of the film formed and prevent it from cracking or
Natural Polysaccharides as Film Former: Feasibility Study
film formers, plasticizer, saliva stimulating agents, sweetening agents and APIs. Various film formers were employed, investigated and reported. 17-19. In most of the cases, RDFs were developed by using maltodextrin. 20-21, HPMC (Methocel) 22-23. or polyvinyl alcohol. 24. as film former. Earlier rapid dissolving films of ondansetron have been
ORALLY FAST DISSOLVING FILMS: INNOVATIONS IN FORMULATION AND TECHNOLOGY
film formers. The physicochemical characteristic of the polymer or polymers selected for film formulation play a vital role in determining the resultant disintegration time of the cast thin film oral dosage form 16-21. Plasticizer Plasticizer is a vital ingredient of the fast dissolving films.
Fabrication and Characterization of Luliconazole Film-Forming Topical
Plasticizers like PEG400 were used in the formulation depending upon the visual appearance of the films. The effect on film flexibility was studied through spraying on cellophane paper and an aluminium foil and folding it a number of times to understand the endurance on folding and film cracking as given in Table 3.
- Why are plasticizers important in film forming?
- Plasticizers are a very important component of the film-forming formulation. They are to be added in a minute amount in the formulation to provide the necessary flexibility to the film and to enhance the water permeation through the film.31Some plasticizers also act as drug diffusion enhancers along with providing plasticity to the film.
- Which polymers can be used to prepare film-forming formulations?
- Both natural and synthetic polymers can be useg to prepare the film-forming formulations. There is wide variety of options of the film-forming formulations like solvent, gel and emulsions too. Metered-dose sprays give more accurate dose with more ease for application. Patient compliance is expected to increase with the help of this concept.
- How many types of film formers are there?
- Essentially, there are 2 kinds of film formers. Water-soluble polymers have a hydrophilic nature, and while many of them are not suitable for enhancing substantivity in conventional skin-surface formulations. They are ideal for formulations in which the drug rapidly penetrates the stratum corneum to form a drug reservoir.
- Which polymers are used for fast dissolving mouth film?
- In this review article, various polymers are utilized for the formulation of fast dissolving mouth film like Pullulan, Gelatin, Sodium Alginate, Pectin, Rosin, Starch, Chitosan are discussed together about their physicochemical properties and film shaping properties.
- What is a film-forming system?
- A film-forming system is a novel approach that has dosage forms (hydrogels and films). As an additional advantage, it has controlled drug-releasing properties. To formulations. The types and concentrations of polymers and characteristics are all covered in this article.
- Can film framing polymers be used in oral films?
- The utilization of film framing polymers in oral films has pulled in impressive consideration in clinical and nutraceutical applications. The determination of polymer is one of the most significant and basic parameters for the effective improvement of the film formation.
