Introduction

Mouth Dissolving films that are intended to dissolve in the mouth are known as mouth dissolving films. Although they can also be used to provide vitamins or minerals, medications are the usual usage for them. There are several materials used to make mouth dissolving films, such as hydroxypropyl methylcellulose, polyvinyl acetate, and cellulose acetate. Usually slender and malleable, they can be seasoned to enhance their flavor [1]. Because mouth dissolving films are absorbed through the oral mucosa, they provide medicine in a quick and effective manner. Because they don’t need water to ingest, they are also quite practical. Both over-the-counter and prescription options are available for mouth dissolving films [2].

Acetaminophen, nitroglycerin, and ibuprofen are a few typical drugs that come in mouth dissolving film form. A secure and efficient method of delivering medicine is by mouth dissolving films. They might not, however, be appropriate for everyone. For instance, oral dissolving films might not be suitable for use by those who suffer from certain medical problems, such as dry mouth [3]. Furthermore, for those with certain illnesses like gastroesophageal reflux disease (GERD), mouth dissolving films might not be as beneficial as alternative drug formulations like pills or capsules. The film is the perfect intraoral fast-acting medication delivery device [4].

Many medications, such as those for erectile dysfunction, analgesics, antihistamines, neuroleptics, cardiovascular medications, and analgesics, can be made as mouth dissolving films [5].

Due to its many advantages, rapid or quick dissolving oral thin films are becoming a more and more common drug delivery method. They are especially good for pediatric and elderly people since they dissolve in saliva in a matter of seconds without the need for water. Drug dispersion in the polymer matrix promotes quick dissolve since the majority of polymers used in mouth dissolving films (MDFs) are amorphous [6]. These benefits increase patient compliance and encourage pharmaceutical manufacturers to spend money switching out their current line of medications to MDFs. Because of its novelty, ease of administration, improved solubility, and subsequent patient compliance, mouth dissolving film (MDF) is a superior option than oral disintegrating tablets [7].

The films are meant to dissolve in a matter of seconds when they come into touch with a moist surface, such the tongue, so the user may swallow the product without adding more liquid. This simplicity of use boosts patient compliance and gives a marketing edge.

In order to provide a therapeutic or pharmacological impact, the mouth dissolving film (MDF) is frequently utilized for systemic drug delivery. MDF formulations bypass first pass metabolism, which improves systemic bioavailability. No need to drink water. Accessible in a range of forms and sizes [8].

The oral route is the most popular method for administering drugs since it is flexible, non-invasive, patient- acceptable, and easy to administer. When it comes to the oral route of medicine administration, several alternatives have been continually given for patients who are nauseated, elderly, juvenile, or noncompliant by using current innovative technology. Adhesive tablets, gels, and patches-among the bio adhesive mucosal dosage forms-are products of technical advancement [9]. The use of polymeric films, among other dosage forms, to transport medicine into the buccal cavity has shown a lot of promise recently. When applied to the tongue, mouth dissolving films release the active medicinal ingredient from the dosage form and instantly hydrate the saliva after dissolving and/or disintegrating [10].

Mouth dissolving films are a kind of formulation that are frequently made using hydrophilic polymers, which allow for quick dissolving in saliva. The most common types of oral disintegrating drug delivery methods are mouth dissolving tablets and mouth dissolving films (MDFs). These devices were created in the latter part of the 1970s as an alternative to traditional dose forms, such as fast-dissolving pills and capsules for young patients and the elderly who have trouble swallowing traditional dosage forms. An Mouth Dissolving Film is typically the same size as a postage stamp. When Mouth dissolving tablets was first introduced to the market, it was closely linked to patient education for proper administration, including instructions such as “do not chew/ do not swallow” [11].

Still, events involving swallowing and chewing were frequently reported despite these recommendations. The people were, however, freed from these negative occurrences by MDFs the following are only a few benefits of administering MDFs, among many others:

High mechanical strength, quick disintegration, low choking dangers, and no costly lyophilization are some of MDFs’ qualitative characteristics. Due to its special qualities and quick disintegration period, which may be anywhere from a few seconds to a minute, ODFs have become extremely important in the pharmaceutical business. A range of medications, such as those with anti-tussive, anti-epileptic, anti-asthmatic, expectorant, and other pharmacological actions, can be included thanks to MDFs’ design. One drawback of MDFs is that they cannot be used with large dosage loading due to their extreme sensitivity to moisture and temperature, which requires costly packaging [12].

Objective of Mouth Dissolving Films

Current Scenario of Mouth Dissolving Films

A growing number of people are using rapid or quick dissolving oral thin films as a medicine delivery method due to its many great advantages. Because it dissolves in saliva quickly and doesn’t require water, it’s especially good for elderly and pediatric patients. The medicine is dispersed in the polymer matrix to facilitate quick dissolve, as most of the polymers used in mouth dissolving films (MDFs) are amorphous. Pharma manufacturers are compelled to spend in switching from their current products to MDFs due to these advantages, which also improve patient compliance [13].

One of the most popular ways to administer drugs is orally as it is more practical, affordable, and leads to high levels of patient compliance. The oral route is a challenge for elderly and pediatric patients who have trouble swallowing and are afraid they may choke. Newer and safer medication delivery methods have been introduced as a consequence of research focused on patient convenience and compliance. Because they dissolve quickly and allow for self- administration without the need for water or chewing, fast dissolving medication delivery systems have become more and more popular and accepted as one example of a system that offers consumers more choice [14].

Disadvantages 0f Mouth Dissolving Film

1. Drugs which are unstable at buccal pH cannot be administered.
2. Drugs which irritate the mucosa cannot be administered by this route.
3. Drug with small dose requirement can only be administered.
4. Taste masking- Most drugs have bitter taste, and need taste masking.
5. Special packaging- MDFs are fragile and must be protected from water so it needs special packaging.
6. Dose uniformity is a technical challenge
7. Expensive packaging of oral film.
8. High dose cannot be incorporated into the oral film.
9. It is hygroscopic in nature so it must be kept in dry places.

Formulation

In the formulation of mouth dissolving films up to 15 mg of the active pharmaceutical component may be added with various excipients, such as plasticizers, colorants, sweeteners, flavor masking agents, etc. Plasticizer lowers the glass transition temperature of polymers by improving the workability, spread ability, and flexibility of films [15].

• Composition of a typical ODF.
• Components Conc. (%)
• Active pharmaceutical ingredient 1–25
• Hydrophilic polymer 40–50
• Plasticizer 0–20
• Color, filler, flavor 0–40

Active Pharmaceutical Ingredient

Anti-histamine, anti-diarrheal, anti-depressant, vasodilator, anti-asthmatic, anti-emetic, and other medication classes are among those that can be included in MDFs. For the purpose of disguising flavor, MDFs can also contain dimenhydrinate. Many medications, such as salbutamol sulfate, rizatriptan benzoate, verapamil, ondansetron, dexamethasone, rofecoxib, cetirizine, pilocarpine, tianeptine sodium, indomethacin, etc., are frequently included in MDFs. Microcrystalline cellulose and other film-forming polymers were also used to create an MDF of an anti-emetic drug similar to prochlorperazine [16].

Hydrophilic Polymers

The appropriate choice and concentration of polymers are essential for the effective formation of an MDF since these parameters are closely linked to the mechanical strength of the films. To change the characteristics of films, they can be applied singly or in conjunction with other polymers. While creating an MDF, the concentration of the polymers being employed is also crucial. The kind and concentration of the polymer must be carefully chosen to ensure the integrity of quickly disintegrating oral films. In order to achieve the appropriate features and properties for the film, the polymer concentration employed in the preparation of MDFs can be raised up to 60–65% w/w of the total weight of dry thin strip. This concentration is typically about 45% w/w. certain qualities are required of the polymer utilized as a film- forming agent in the formulation of thin strips [17].

Ideal Properties of Hydrophilic Polymers

• Properties
• Not irritating
• Should not impede the MDF’s disintegration time
• Reasonably priced
• Should have decent spread ability, a suitable tensile strength, and acceptable mechanical qualities. It should also have an appropriate shelf life.
• Not harmful
• Not irritating
• Both synthetic and natural polymers are now employed in the development of ODF formulations.

Most Commonly Used Natural and Synthetic Polymers in ODFs

Type of polymer and examples

• Natural - Starch, polymerized rosin, pullulan, sodium alginate, Pectin, gelatin, and maltodextrins
• Synthetic- Polyvinyl alcohol, hydroxy propyl methyl cellulose, sodium carboxy methyl cellulose, polyvinyl pyrrolidone, and hydroxy propyl cellulose.

To modify the various characteristics of films, several polymers are utilized. Films containing pullulan offer strong tensile strength and stability across a wide temperature range, in addition to pullulan’s enhanced solubility. The qualities of produced films are influenced by the molecular weights of the gelatins used. A film that is notably more attractive may be achieved by utilizing polymers with an average molecular weight that are higher [18].

Superior quality strips are produced when chitosan and either low methoxy pectin (LMP) or high methoxy pectin (HMP) are combined. Owing to their hydrophilic nature, cellulose-derived film-forming polymers, such as carboxymethyl cellulose (CMC), methyl cellulose (MC), hydroxypropyl cellulose (HPMC), and hydroxypropyl cellulose (HPC), produce films with a lower water vapor barrier. When combined with other polymers or used alone, polyethylene glycol (PEG) possesses strong film-forming qualities as well [19].

Various grades, such as Methocel E3, Methocel E5, and Methocel E15 Premium LV, are available from HPMC, which is an excellent film former. It was shown that Methocel E15 Premium LV produced films with the right qualities when triclosan was developed into a fast-dissolving film using various grades of HPMC. Quick-dissolving famotidine film made with polyethylene glycol (PEG) and HPMC showed the intended physico-chemical characteristics. Fast dissolving films were made with maltodextrins (MDX) and an equal low dosage of dextrose, and a water-insoluble medication called piroxicam was added. Changes in polymer content have a significant impact on both mechanical characteristics and drug release percentage, as demonstrated by ODFs of nebivolol HCl produced from HPMC, pullulan, and polyvinyl pyrrolidone (PVP) [20].

Mono- and double-layered chlorhexidine buccoadhesive films were developed to illustrate the fact that polymers control the release profile. Films produced with alginate, HPMC, and/or chitosan improved drug release. The mechanical characteristics and film strength were demonstrated by the granisetron hydrochloride ODFs, which were produced using pullulan and HPMC, contrasting the impact of polymer concentration. While films with up to 40% HPMC content were difficult to peel, films with pullulan concentrations of 40–45% did not produce films with high qualities. Furthermore, at concentrations greater than 50%, the stickiness of the film increased [21].

An investigation into the production of fast-dissolving films of losartan potassium using varying quantities of polyvinyl alcohol (PVA) and maltodextrins (MD) revealed a clear relationship between increasing polymer concentration and in vitro disintegration time [22].

Manufacturing Techniques of Mouth Dissolving Films

Mouth dissolving films are produced using a variety of techniques, including rolling, solvent casting, hot-melt extrusion, semisolid casting, and solid-dispersion extrusion. The writers go over these techniques as well as the many metrics used to assess dissolving films.

When applied to the tongue, oral thin films, also known as Mouth dissolving films (MDFs), offer an active pharmaceutical ingredient (API) with rapid release. Orally disintegrating tablets have an alternative in the form of MDFs. The patient applies these dose forms on their tongue or other oral mucosal tissue. Saliva quickly hydrates the film and causes it to stick to the application location. It dissolves and disintegrates quickly, releasing the medication for mucosal absorption or-with some modifications—allowing for oral gastrointestinal absorption with fast-acting dissolve ability [23].

Originally, these films were marketed as mouthwashes with thymol and menthol in them. These films are offered as breath-freshening products by Boots (Nottingham, UK), Wrigley (Chicago), and Johnson & Johnson (New Brunswick, NJ) in the United States and Europe. In the US, Zengen (Woodland Hills, CA) manufactures a chloraseptic relief strip that contains benzocaine, a local anesthetic used to treat sore throats [24].

These ODFs include film-forming polymers such sodium alginate, pectin, starch, carboxymethyl cellulose (CMC), hydroxypropylmethyl cellulose (HPMC), and hydroxypropyl cellulose (HPC). Plasticizers, coloring, thickening, saliva- stimulating, sweetening, and flavoring agents are among the other substances that are added. Fast dissolving films can be used as transdermal nicotine replacement therapy, as well as antihistamine and anti-ulcer medications. Prescription medications for sleeping disorders and antipsychotics are potentially possible options.

ODFs provide several benefits, such as enhanced mobility, simplicity in administration, precise dosage, economic viability, and better patient adherence [25].

Manufacture of MDFs

Heat-melt extrusion (HME), rolling, solvent casting, semisolid casting, and solid-dispersion extrusion are processes that can be employed alone or in combination to create MDFs. The two most popular processes for making films are HME and solvent casting [26].

The solvent-casting technique. Preferably, the solvent- casting process is used to formulate the MDF, dissolving the water-soluble components to create a transparent, viscous solution. Smaller quantities of the API and other agents are dissolved in the solution and mixed in with the bulk medication. The watery, viscous solution receives this combination added to it. A vacuum is used to release the trapped air. To achieve homogeneous film properties and thickness, desecration is required. The final mixture is poured into a film, given time to dry, and then divided into the required size pieces. The choice of an appropriate solvent is greatly influenced by the characteristics of the API [27].

The API’s physicochemical characteristics have to be taken into account. These characteristics include the API’s temperature sensitivity, compatibility with solvents, compatibility with other film-forming excipients, and polymorphism. MDFs must be manufactured and packaged with extra care to regulate the impact of moisture. The presence of moisture considerably affects the film’s mechanical characteristics and stability. Temperature is another element that needs to be well regulated. The viscosity of the solution and the API’s temperature sensitivity must be maintained under controlled temperature settings [28].

Pouring the solution over an inert foundation requires specialized tools, including rollers. The necessary film thickness is determined by the space between the roller and the substrate. The last stage, drying the film, assists to produce the final result by getting rid of the solvent. Film casting often uses glass, plastic, or Teflon plates as an inert basis. A number of issues might arise when manufacturing technology is moved from the lab to the production level. These issues may involve the casting of the film, achieving a consistent film thickness, and appropriately drying the sample. The last stage of drying requires choosing the right kind of drier [29].

After the films have dried, they are cut, stripped, and packaged. Films with the right dimensions and forms can be cut. Films are often available in two and three-by-two- centimeter diameters. A criteria for the MDF that is equally significant is the choice of packing container. Enough mechanical strength should be provided by the packaging container to shield the film from the elements and from shipping-related stresses like humidity and temperature. Single-unit containers and multiple-unit dispensers can be chosen based on the features of the film. Prior to being placed inside a secondary packing container, the packaged films are examined [30].

Extrusion using a hot melt. Granules, sustained-release pills, and transdermal and transmucosal drug delivery devices are frequently made using HME. The pharmaceutical sector has lately seen a rise in the use of the HME procedure. Formulators can generate desired drug-release profiles by extruding mixtures of medicines, polymers, and plasticizers into different final forms, based on information from the plastics industry. Using this method of processing films, a polymer is shaped into a film by heating it instead of using the conventional solvent-casting approach [31].

Advantages of HME for Film Formation Include the Following

• No need to use water or a solvent
• Fewer stages in the processing
• The API’s compressibility characteristics might not be significant.
• Effective dispersion method for poorly soluble medications
• Because of the vigorous mixing and agitation, the tiny particles were more evenly dispersed.
• Using less energy than high-shear techniques
• Minimal amount of product waste
• Potential for scaling up
• Good management of the parameters of operation.

Melting the material into a liquid form and pushing it out of the hot-melt extruder are the steps in the HME process. The procedure begins with mixing the API and other excipients in a dry condition. The total solvent removal provided by this technique is its benefit. After cooling, the films are trimmed to the appropriate length. It is appropriate for medications that are thermo stable due to the elevated temperature used in the procedure. This procedure prohibits the use of drugs that are temperature sensitive [32].

Unlike HME, which needs thermos table pharmaceuticals and is anhydrous, solvent casting is a hydrous method that may be used with thermo labile and thermo stable medications. The effects of topical HPC films by HME were investigated by Repka et al. using chlorpheniramine maleate (CPM) (5). According to reports, CPM acts as a potent plasticizer that concentration-dependently increases % elongation and decreases tensile strength. Because CPM permits film processing at lower temperatures, it also serves as a processing aid for hot-melt film extrusion [33].

Examining HPC films with seven polymer additions in vivo and their in vivo bioadhesive qualities on human subjects’ epidermis was done (7). HME produced additive- containing HPC films both with and without plasticizers. HPC films’ bio adhesion was greatly enhanced by the addition of polycarbophil and a carbomer (Carbopol 971P NF, Lubrizol, and Cleveland, OH). Utilizing HME to produce solid dispersions was the subject of several investigations. Amorphous solid-solutions were found to occur when miscible components were melt extruded, but crystalline excipients produced amorphous drug dispersion when immiscible components were extruded [34].

Solid dispersions may be made using this method in a single step. An extruder is made up of two separate components. A conveyer system that moves the material and applies some distributive mixing makes up the first section. A dye system, the second component, shapes the materials into the desired shape. The extruder conveys, mixes, and melts the drug-carrier mix once it has been filled in the hopper. The melt is shaped by the die into the desired shape, such as films, granules, pellets, or powder, which can then be processed further to create regular tablets or capsules. For materials that are prone to oxidation and hydrolysis, all oxygen and moisture should be removed [35].

Evaluation of the MDF

Numerous factors are taken into consideration while evaluating the ODF, including its thickness, mechanical qualities, folding durability, assay/drug content, and investigations conducted on its surface morphology, taste, and in-vitro disintegration and dissolution.

Characterization of MDFs

Many investigations and measurements are performed as part of the characterization studies of the produced OTFs. These include the following: degree of transparency; X-ray powder diffraction (XRD), X-ray electron microscopy (SEM), fourier transform infrared spectroscopy (FT-IR), and differential scanning calorimetry (DSC) analyses and measurements; moisture absorption; swelling ability; flexibility (elongation); folding ability; pH determination; weight variability; thickness; flavor; content uniformity; dispersion; dissolution rate; release kinetics; and degree of transparency.

MDFs are challenging to differentiate because of the brief durations of the disintegration and dissolution processes. The disintegration test can be used instead of the dissolution test for ODTs, according to the American Association of Pharmaceutical Scientists/International Pharmacy Federation. The pace at which API is released as the film dissolves depends only on whether the API is molecularly dissolved in OTF. The dissolving rate and disintegration time tests are also advised if the API is distributed in a particulate form in the film matrix. The FDA and USP (American Society for Pharmaceuticals) advise that ODTs dissolve in 30 seconds or less, despite the European Pharmacopoeia allowing up to three minutes for this process.

Since the saliva volume in the mouth is less than 2 mL, these tests are generally recommended in a small environment for disintegration testing in 2-7 mL of fluid under similar conditions prevailing in the oral cavity. OTF can be placed on the surface of the liquid in a petri dish, and the disintegration time can be determined utilizing a chronometer. In the meantime, the petri dish can be shaken continuously to mimic the tongue’s mouth movement. This method is simple and offers ease of application. Otherwise, it creates some difficulties, and the process is very difficult to apply to automation.

According to the pharmacopoeia’s guidelines for solid oral dosage forms, drug release from MDFs is typically conducted using a pallet or basket device in an environment with a temperature of 37°C (artificial saliva fluid or a pH 6.8 phosphate buffer). On the other hand, MDFs have several drawbacks with the dissolving equipment. In contrast, while using the pallet apparatus, MDFs are likely to stay to the bottom of the container in the dissolving liquid or remain on the top. While utilizing the basket apparatus, this might lead to adhering to the edges and clogging of the basket pores. To mimic adherence in vivo and inhibit swimming, platinum and double-sided tapes are employed. Each film is fastened to the bottom of the dissolving media and set on a rectangular glass plate. The medication is released extremely quickly as a result of the fast disintegration, and specimens of the examined medium are taken quickly.

Using a dissolving test device, the taste-masking characteristics of MDFs may be assessed in vitro. The safest method of testing is in vivo, however using volunteers has ethical challenges. Prior to the experiment, participants’ sensory sensitivity thresholds are measured against four reference materials and tastes. These tastes are tartaric acid (sour), quinine (bitter), sucrose (sweet), and sodium chloride (salty). Using pure water, the volunteers first cleanse their lips. After that, they put a film specimen with the same dosage of drug and a quantity of pure drug on their tongues for 30 seconds each. The volunteers then rinse their lips with water after spitting. After that, they are put through a taste evaluation procedure that has three rating levels: 0 for tasteless, 1 for somewhat bitter, 2 for moderately bitter and 3 for extremely bitter.

Numerous research on OTFs’ usage as stand-ins for commercially available conventional medications in the treatment of a variety of disorders have been published in the literature. The following APIs were used in these studies: cinitapride hydrogen tartarate, meloxicam, escitalopram, phenylephrine HCl, ondansetron HCl, fluticasone propionate, ergotamine, zolpidem tartrate, bufotenine, etoricoxib, levocetirizine dihydrochloride, leukotriene receptor antagonist, meloxicam, escitalopram, ergotamine, fluticasone propionate, and caffeine.

Clinical and Regulatory Requirement

A shortened new drug application is necessary to show a product’s bioequivalency to an oral medication that is currently on the market. Considerations include therapeutic equivalency and in vitro dissolution tests. An oral disintegrating tablet and an ODF can be compared for comparative bioequivalency. A novel dosage form is identified in the event that the ODF has a distinct target pharmacokinetic profile from the already marketed medication. One further clinical research is needed for a new dose type. A three-year marketing exclusivity period for the product is provided by a recent clinical trial. In the event if the molecule is identical to that of the authorized medication, preclinical toxicity studies are not needed. Such trials are intended to demonstrate qualities related to safety, tolerability, and effectiveness. Testing on oral mucosa is done on both people and animal models. The best model to predict irritation criterion prior to human testing is the hamster-cheek pouch.

Challenges that are faced during Formulation of Mouth Dissolving Films

1. A medication solubility-related issue.
2. For the unpleasant medications, a specific flavor masking agent is needed.
3. The inability to maintain dose consistency.
4. The financial difficulties associated with organizing the packing supplies.
5. Issues with medication storage that compromise content preservation.
