Drug delivery systems (DDS) often comprise biopharmaceuticals in aqueous form, making them susceptible to physical and chemical degradation, and therefore requiring low temperature storage in cold supply and distribution chains. Freeze-drying, spray-drying, and spray-freeze-drying are some of the techniques used to convert biopharmaceuticals-loaded DDS from aqueous to solid dosage forms. However, the risk exists that shear and heat stress during processing may provoke DDS damage and efficacy loss. Supercritical fluids (SCF), specifically, supercritical carbon dioxide (scCO2), is a sustainable alternative to common techniques. Due to its moderately critical and tunable properties and thermodynamic behavior, scCO2 has aroused scientific and industrial interest. Therefore, this article reviews scCO2-based techniques used over the year in the production of solid biopharmaceutical dosage forms. Looking particularly at the use of scCO2 in each of its potential roles—as a solvent, co-solvent, anti-solvent, or co-solute. It ends with a comparison between the compound’s stability using supercritical CO2-assisted atomization/spray-drying and conventional drying.

Improving drug bioavailability in the pharmaceutical field is a challenge that has attracted substantial interest worldwide. The controlled release of a drug can be achieved with a variety of strategies and novel materials in the field. In addition to the vast development of innovative materials for improving therapeutic effects and reducing side effects, the exploration of remarkable existing materials could encourage the discovery of diverse approaches for adapted drug delivery systems. Recently, superdisintegrants have been proposed for drug delivery systems as alternative approaches to maximize the efficiency of therapy. Although superdisintegrants are well known and used in solid dosage forms, studies on strategies for the development of drug delivery systems using superdisintegrants are lacking. Therefore, this study reviews the use of superdisintegrants in controlled drug release dosage formulations. This overview of superdisintegrants covers developed strategies, types (including synthetic and natural materials), dosage forms and techniques and will help to improve drug delivery systems.

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.

Microparticles, microspheres, and microcapsules are widely used constituents of multiparticulate drug delivery systems, offering both therapeutic and technological advantages. Microparticles are generally in the 1–1000 µm size range, serve as multiunit drug delivery systems with well-defined physiological and pharmacokinetic benefits in order to improve the effectiveness, tolerability, and patient compliance. This paper reviews their evolution, significance, and formulation factors (excipients and procedures), as well as their most important practical applications (inhaled insulin, liposomal preparations). The article presents the most important structures of microparticles (microspheres, microcapsules, coated pellets, etc.), interpreted with microscopic images too. The most significant production processes (spray drying, extrusion, coacervation, freeze-drying, microfluidics), the drug release mechanisms, and the commonly used excipients, the characterization, and the novel drug delivery systems (microbubbles, microsponges), as well as the preparations used in therapy are discussed in detail.

Fast Disintegrating Tablets

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.
