The topical route is the most preferred one for administering drugs to eyes, skin and wounds for reaching enhanced efficacy and to improve patient compliance. Topical administration of drugs via conventional dosage forms such as solutions, creams and so forth to the eyes is associated with very low bioavailability (less than 5%) and hence, we cannot rely on these for delivering drugs to eyes more efficiently. An intravitreal injection is another popular drug delivery regime but is associated with complications like intravitreal hemorrhage, retinal detachment, endophthalmitis, and cataracts. The skin has a complex structure that serves as numerous physiological barriers to the entry of exogenous substances. Drug localization is an important aspect of some dermal diseases and requires directed delivery of the active substance to the diseased cells, which is challenging with current approaches. Existing therapies used for wound healing are costly, and they involve long-lasting treatments with 70% chance of recurrence of ulcers. Nanotechnology is a novel and highly potential technology for designing formulations that would improve the efficiency of delivering drugs via the topical route. This review involves a discussion about how nanotechnology-driven drug delivery systems have evolved, and their potential in overcoming the natural barriers for delivering drugs to eyes, skin and wounds.

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 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 conventional drug delivery systems have a long list of issues of repeated dosing and toxicity arising due to it. The hydrogels are the answer to them and offer a result that minimizes such activities and optimizes therapeutic benefits. The hydrogels proffer tunable properties that can withstand degradation, metabolism, and controlled release moieties. Some of the areas of applications of hydrogels involve wound healing, ocular systems, vaginal gels, scaffolds for tissue, bone engineering, etc. They consist of about 90% of the water that makes them suitable bio-mimic moiety. Here, we present a birds-eye view of various perspectives of hydrogels, along with their applications.

Pass Metabolism

In the recent days about 75% of the drugs taken orally are does not show the desired therapeutic effect. Oral conventional dosage forms have several disadvantages such as poor bioavailability due to hepatic first pass metabolism and tendency to produce rapid blood level spikes (Both high and low). Thus, rapid drug levels in the plasma leads to a need of high and/or frequent dosing, which can be both uneconomical and inconvenient. To overcome such disadvantages transdermal drug delivery system was developed. TDDS is such a delivery system which has been explored extensively over the last two decades, with therapeutic success. Transdermal drug delivery systems (TDDS) are the drug delivery systems which involves transportation of drug to epidermal and dermal tissues of the skin for local therapeutic action while major fraction of the drug is transported into the systemic blood circulation. Topical administration of therapeutic agents offers vast advantages over conventional oral and invasive methods of drug delivery. Some of the advantages of transdermal drug delivery include limitation of hepatic first pass metabolism, enhancement of therapeutic efficiency and maintenance of steady state plasma level concentration of the drug. This study includes a brief overview of TDDS, its advantages over conventional dosage forms, drug delivery routes across human skin, permeation enhancers, and classification, formulation, methods of preparation and evaluation of transdermal patches.

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.
