Purpose: The aim of this article is to present a review of mucoadhesion drug delivery systems. The review covers the mucoadhesive concepts, polymers used, theories and mechanisms of mucoadhesion, and factors affecting the mucoadhesive dosage forms. Study Design: An extensive review was carried out on mucoadhesion formulations, applications, mechanisms, theories, and polymers used in these dosage forms. Results: Mucoadhesive drug delivery system can interact with the mucus membrane, which covers the mucin molecules and mucosal epithelial surface. This interaction leads to an increment of the dosage form residence time at the site of absorption and hence increasing the bioavailability, efficacy of drugs, and improving therapeutic outcomes. Polymers are used to provide muco-adhesion of the dosage form, enhancing drug release pattern, solubility and dissolution of inadequately soluble drugs. Conclusion: Mucoadhesive drug delivery systems were found to be the best alternative approaches for the traditional dosage forms to enhance bioavailability of poorly soluble drugs and to avoid GIT degradation and first pass metabolism of some drugs.

The concept of mucoadhesion was started in early 1980’s with the aim of controlled delivery of drugs. Mucoadhesion is simply defined as the adhesion between two materials, in which one is the mucosal surface and the another one is the mucoadhesive dosage form. In the recent decades, mucoadhesive drug delivery system draw the attention in the gastroretentive delivery system. Mucoadhesive drug delivery systems interact with the mucus layer covering the mucosal epithelial surface, and mucin molecules and increase the residence time. Mucoadhesive dosage forms are designed to increase the retention of the drug/dosage form at the application site, to provide a controlled release of drug for increased curative consequence. The medications which have local action or those which have maximum absorption in gastrointestinal tract require increased duration of stay in GIT. Mucoadhesive drug delivery systems were prepared by using either natural or synthetic polymers, which is interacting with the mucous layer and used to prevail over the physiological barriers for extended drug delivery. The mucoadhesive ability of a dosage form is depending upon variety of factors, such as the nature of the mucosal tissue and the physicochemical properties of the polymeric formulation. This review article aims to provide an overview of the various theories of mucoadhesion, properties of mucoadhesive materials, methods to study the mucoadhesion, and finally various mucoadhesive dosage forms.

Over the past few decades, there has been an increased interest for innovative drug delivery systems to improve safety, efficacy and patient compliance, thereby increasing the product patent life cycle. The discovery and development of new chemical entities is not only an expensive but also time consuming affair. Hence the pharmaceutical industries are focusing on the design and development of innovative drug delivery systems for existing drugs. One such delivery system is the fast disintegrating oral film, which has gained popularity among pediatric and geriatric patients. This fast disintegrating film with many potential benefits of a fast disintegrating tablet but devoid of friability and risk of choking is more acceptable to pediatric and geriatric patients. Formulation of fast disintegrating film can be achieved by various techniques, but common methods of preparation include spraying and casting. These film forming techniques use hydrophilic film former in combination with suitable excipients, which allow the film to disintegrate or dissolve quickly in the mouth within a few seconds without the administration of water. In view of the advantages of the fast disintegrating films over the fast disintegrating tablets and other dosage forms, it has the potential for commercial exploitation. The oral film dosage form not only has certain advantages of other fast disintegrating systems but also satisfies the unmet needs of the market. The present review emphasizes on the potential benefits, design and development of robust, stable, and innovative orally fast- disintegrating films and their future scenarios on a global market as a pharmaceutical dosage form.

Rheumatoid arthritis (RA) is a severe systemic inflammatory disease with no cure at present. Recent developments in the understanding of inflammation and nanomaterial science have led to increased applications of nanostructured drug delivery systems in the treatment of RA. The present review summarizes novel fabrications of nanoscale drug carriers using food components as either the delivered drugs or carrier structures, in order to achieve safe, effective and convenient drug administration. Polyphenols and flavonoids are among the most frequently carried anti-RA therapeutics in the nanosystems. Fatty substances, polysaccharides, and peptides/proteins can function as structuring agents of the nanocarriers. Frequently used nanostructures include nanoemulsions, nanocapsules, liposomes, and various nanoparticles. Using these nanostructures has improved drug solubility, absorption, biodistribution, stability, targeted accumulation, and release. Joint vectorization, i.e., using a combination of bioactive molecules, can bring elevated therapeutic outcomes. Utilization of anti-arthritic chemicals that can self-assemble into nanostructures is a promising research orientation in this field.

The World of medicine has gained considerable interest in the research area all over the World. Scientists constantly work on the three parameters ‘Quality, Safety, Efficacy’ of a pharmaceutical ingredient. Refine these parameters; they are continually developing different dosage forms. These unique types of dosage forms help to provide improved bioavailability and efficacy of a pharmaceutical ingredient. The role of dosage form is to improve the availability of the medicine to treat the symptoms and disease. This article focus on the different types of dosage forms, their advantages and some important facts related to that dosage forms.

: The content and the application of pharmaceutical dosage forms must meet several basic requirements to ensure and maintain efficiency, safety and quality. A large number of active substances have limited ability to direct administration. Excipients are generally used to overcome the limitation of direct administration of these active substances. However, the function, behavior and composition of the excipients need to be well known in the design, development and production of pharmaceutical dosage forms. In this review, excipients used to assist in any pharmaceutical dosage form production processes of drugs, to preserve, promote or increase stability, bioavailability and patient compliance, to assist in product identification / separation, or to enhance overall safety and effectiveness of the drug delivery system during storage or use are explained. Moreover, the use of these excipients in drug delivery systems are identified. Excipient toxicity, which is an issue discussed in the light of current studies, also discussed in this review.

The Fast Dissolving Drug Delivery Systems sets a new benchmark was an expansion that came into existence in the early 1980’s and combat over the use of the different dosage form like tablets, suspension, syrups, capsules which are the other oral drug delivery systems. Fast Dissolving Drug Delivery System (FDTS)  has a major advantage over the conventional dosage forms since the drug gets rapidly disintegrated and dissolves in the saliva without the use of water .In spite of the downside lack of immediate onset of action; these oral dosage forms have valuable purposes such as self medication, increased patient compliance, ease of manufacturing and lack of pain. Hence Fast Disintegrating Tablets (FDTS) technology has been gaining importance now-a-days with wide variety of drugs serving many purposes. Fast Disintegrating Tablets (FDTS) has ever increased their demand in the last decade since they disintegrate in saliva in less than a minute that improved compliance in pediatrics and geriatric patients, who have difficulty in swallowing tablets or liquids. As fast dissolving tablet provide instantaneous disintegration after putting it on tongue, thereby rapid drug absorption and instantaneous bioavailability, whereas Fast dissolving oral films are used as practical alternative to FDTS. These films have a potential to deliver the drug systemically through intragastric, sublingual or buccal route of administration and also has been used for local action. In present review article different aspects of fast dissolving  tablets and films like method of preparations, latest technologies, evaluation parameters are discussed. This study will be useful for the researchers for their lab work.
