Oral routes are most commonly preferred route for delivering drug. Most common oral dosage forms are tablet and capsules. But many patients such as geriatric, pediatric and dysphasic patients find difficult to swallow conventional tablet and capsule. To overcome various problems related to swallowing, Fast dissolving Tablets (FDTs) were designed in early 19th century and hence further advancement has led to development of Fast Dissolving Oral Films (FDOFs). In the recent years, many of the pharmaceutical groups are focusing their research on rapid dissolving technology. Amongst the plethora of avenues explored for rapid drug releasing product, FDOFs technology is gaining much attention. These are solid dosage forms, which disintegrate or dissolve within 1 min when placed in the mouth without drinking water or mastication. This technology has been used for local action as well as rapid release products. The fast dissolving oral films are formulated using various Active pharmaceutical ingredients (API), film forming polymers, plasticizer, flavors, colors and sweeteners. Initially FDOFs are up to breath strips, confection and oral care markets. But now it became a novel and widely accepted technology for delivering OTC and prescription medication too.Sunsari Technical College Journal 2015, 2(1):58-68

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.

In recent years, gastroretentive drug delivery system (GRDDS) has gained researcher’s interest in the field of oral drug delivery. Various GRDDS approaches can be utilized to retain the dosage forms in the stomach and to release the drug slowly for an extended period of time. GRDDS can be used to prolong the residence time of delivery system in the stomach. This results in targeting of drug release at a specific site for the systemic or local effects. GRDDS can be used to overcome challenges associated with conventional oral dosage forms and to release the drug at a specific absorption site to improve bioavailability of particular drug substance. The challenges include fast gastric emptying of the dosage form which results in the poor bioavailability of the drug. Prolongation of the retention of drugs in stomach those having low solubility at high intestinal pH improves the solubility of drugs. GRDDS has proved to be effective in systemic actions as well as in local actions to treat gastric or duodenal ulcers. Local activity in the upper part of the small intestine can be obtained by improving the residence time of delivery system in the stomach. The system is useful for drugs which are unstable in the intestine or having a low solubility/permeability in the small intestine. Various GRDDS approaches include high density (sinking) systems, low-density (floating systems), mucoadhesive, expandable, unfoldable, superporous hydrogel systems, and magnetic systems.

Drug delivery by the oral route is the most prescribable and acceptable route in terms of patient’s compliance. Improvement of patient’s compliance has always a challenge towards the development of oral drug delivery system. In the market different types of oral dosage forms are available in which tablets, capsules, syrups, suspensions are preferred ones. Oral solid drug delivery faces drawback in case of swallowing especially with paediatrics and geriatric psychotic patients. Therefore scientists attracted towards fast mouth dissolving drug delivery systems to encounter existing problems with unique property of palatability and rapid disintegration. The concept of fast dissolving tablet came into existence in late 1970 and further improvements are still going on in connection with its preparation and methodology. Fast dissolving tablets have faster disintegration and dissolution rate and releases within 30 seconds as they come in contact with saliva. These systems also obviate the requirement of carry water during drug administration. This facilitate drug delivery to the patients of dysphasic, psychic, paediatrics, geriatric and bed-ridden, unconscious population. As fast dissolving tablets falls under desired expectation of safer, convenient and economical solid dosage forms, several techniques have been developed to improve disintegration quality in the recent past years. This article mainly focuses on formulation and evaluation technologies with recent advancement made so far in the field of fast dissolving tablets. Keywords: Fast disintegration; Dysphasia; Mouth dissolving; Self-medication.

The purpose of any selected drug delivery system (DDS) is to deliver drug to target site and to get the desired drug concentration for effective therapy. The main purpose of designing controlled or sustained DDS is to decrease the frequency of dosing and maximizing its efficiency by confining the area of action of the drug to a selected region. It is well-identified that solid oral dosage form, particularly tablets, is the most satisfactory form of delivering medication. In addition, some new variations are emerging such as mini tabs which offer more formulation flexibility. Oral controlled release DDS are classified into two categories like single unit dosage forms which include tablets, capsules, and multiple-unit dosage forms include pellets, granules, or mini tablets. Mini tablets are a new development in solid dosage forms and more beneficial and great substitute for granules and pellets. Mini tablets defined as tablets which are having diameter <3 mm and promising patient friendly drug delivery system and more acceptable in small children’s and old age people as they are easy to swallow and offer therapeutic benefits such as manufactured relatively easy, dose and formulation flexibility, combination release pattern, coating, and less solvent requirement. Dose dumping and local irritation can be avoided using mini tablets. This review highlights the various advantages of mini tablets, manufacturing processes, formulation possibilities, and their challenges.

Abstract The aim of the present work was to produce 3D-printed oral dosage forms with a sufficient drug dose displaying various release profiles. Hot-melt extrusion was utilized to produce drug-loaded feedstock material that was subsequently 3D-printed into 6, 8, and 10 × 2.5 mm tablets with 15% and 90% infill levels. The prepared formulations contained 30% (w/w) isoniazid in combination with one or multiple pharmaceutical polymers possessing suitable properties for oral drug delivery. Thirteen formulations were successfully hot-melt extruded of which eight had properties suitable for fused deposition modeling 3D printing. Formulations containing HPC were found to be superior regarding printability in this study. Filaments with a breaking distance below 1.5 mm were observed to be too brittle to be fed into the printer. In addition, filaments with high moisture uptake at high relative humidity generally failed to be printable. Different release profiles for the 3D-printed tablets were obtained as a result of using different polymers in the printed formulations. For 8 mm tablets printed with 90% infill, 80% isoniazid release was observed between 40 and 852 min. Drug release characteristics could further be altered by changing the infill or the size of the printed tablets allowing personalization of the tablets. This study presents novel formulations containing isoniazid for prevention of latent tuberculosis and investigates 3D printing technology for personalized production of oral solid dosage forms enabling adjustable dose and drug release properties.

Oral drug administration to pediatric patients is characterized by a lack of age-appropriate drug products and the off-label use of medicines. However, drug administration practices at hospital wards is a scarcely studied subject. The aim of this study was to explore the oral drug administration practices at pediatric hospital wards, with a focus on experiences and challenges faced, methods used to mitigate existing problems, drug manipulation habits, perceptions about oral dosage forms and future needs of oral dosage forms for children. This was a qualitative study consisting of focus group discussions with physicians, nurses and clinical pharmacists in a tertiary university hospital with the objective of bringing forward a holistic view on this research topic. These healthcare professionals recognized different administration challenges that were classified as either dosage form-related or patient-related ones. A lack of depot formulations developed especially for children as well as oral pediatric dosage forms of drug substances currently available as intravenous dosage forms was recognized. The preferred oral dosage forms were oral liquids and orodispersible tablets. Patient-centered drug administration practices including factors facilitating drug administration both at hospital wards and at home after patient discharge were identified. Among all healthcare professionals, the efficient cooperation in drug prescribing and administration as well as in educating the child’s caregivers in correct administration techniques before discharge and improving the overall discharge process of patients was emphasized. This study complements the prevalent understanding that new dosage forms for children of varying ages and stages of development are still needed. It also brings a holistic view on different aspects of oral drug administration to pediatric patients and overall patient-centered drug administration practices.

Of all drug delivery systems, oral drug delivery remains the most preferred option for administration for various drugs. Availability of wide variety of polymers and frequent dosing intervals helps the formulation scientist to develop sustained/controlled release products. Oral Sustained release (S.R) / Controlled release (C.R) products provide an advantage over conventional dosage forms by optimizing bio-pharmaceutic, pharmacokinetic and pharmacodynamic properties of drugs in such a way that it reduces dosing frequency to an extent that once daily dose is  sufficient for therapeutic management through uniform plasma concentration providing maximum utility of drug  with reduction in local and systemic side effects and cure or control condition in shortest possible time by smallest quantity of drug to assure greater patient compliance. This review describes the various factors influencing the design and performance of sustained/controlled release products along with suitable illustrations.
