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.

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.

NDDS is advanced drug delivery system which improves drug potency, control drug release to give a sustained therapeutic effect, provide greater safety, finally it is to target a drug specifically to a desired tissue. Novel drug delivery system have been developed to overcome the limitation of conventional drug delivery systems, such as of gastric retention by decreasing fluctuations in the concentration of the drug in blood,resulting in the reduction in unwanted toxicity and poor efficiency. As compared to traditional dosage forms bilayer tablets are more efficient for sequential release of two drugs that can be different or identical. Bilayer tablet is also capable of separating two incompatible substances and also for sustained release. Gastro retentive drug delivery system retains the period of dosage forms in the stomach or upper gastro intes-tinal tract ,as to improve bioavailability and the therapeutic efficacy of the drugs. Mainly the bilayer drug delivery system is suitable for drugs whose therapethic windows are narrow in the gastrointestinal tract (GIT) and also they have low elimination half life: 3-4 h. The purpose of this review is to disclose the challenges faced during the formulation of bilayer tablets. Finally, the whole article is firmly analyzed in a concluding paragraph. KEYWORDS: Conventional drug delivery systems, Bilayer tablet, Gastro retentive, Bioavailability

Management of illness through medication is entering a new era in which growing number of novel drug delivery systems are being employed and are available for therapeutic use. Pharmaceutical research and development is currently focused on the development of drug delivery systems to target a drug to the desired organ or site with the aim of minimizing its overall distribution in the body. The oral mucosa has many properties which make it an attractive site for drug delivery but simultaneously provide several problems for researchers for effective and efficient delivery of therapeutic active agents. However, with the development of novel delivery techniques overcome several challenges. Oral mucosa delivery has many advantageslike high blood flow, rapid recovery, prevention of hepatic first-pass effect and pre-systemic elimation in gastrointestinal tract. On the other hand relatively small surface area and significant loss of drug due to swallowing and salivary flow are main limitations of buccal delivery. Different formulations including sprays, tablets, mouthwashes, gels, pastes and patches are presently used for delivery into and/or across the oral mucosa. Over the last 20 years, a wide range of formulations has been developed for buccal drug delivery systems but unfortunately few have been accomplished to be a medicine. One of the main reasons of this unsuccessful result could be the lack of the standardized methods which evaluate in vitro performance of buccal dosage forms. Thus aim of this review, to discuss the potential of buccal drug delivery and buccal dosage forms and also explore recent studies and in vitro analysesmethodology of buccal dosage forms. Peer Review History: UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.

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.
