Oral disintegrating tablets are solid dosage form containing medical substances which disintegrate rapidly, usually within few seconds when placed upon tongue requiring no additional water to facilitate swallowing. Solid dosage forms that can be disintegrated, dissolved, or suspended by saliva in the mouth resulting in easy swallowing can provide significant benefits to the pediatric and geriatric population, as well as other patients who prefer the convenience of easily swallowable dosage forms Superdisintegrants are currently approached and utilized in the formulation of the orally disintegrating tablets. The present work includes isolation of starch from Echinochloa Colona and further characterizing it for various physicochemical and phytochemical analysis. The isolated starch has been modified chemically and its disintegrating efficiency has been tested in tablet formulation; the present work also explores the optimization of concentration of starch in formulation of Ibuprofen tablets in comparison with synthetic and natural superdisintegrants. Phytochemical analysis confirmed the presence of starches and carbohydrates. Results indicated that the Echinochloa Colona starch samples could be potential superdisintegrants in orally disintegrating tablets of Ibuprofen. Tablet performance was found to influence by the way of addition of starch, its concentration and the method of tablet preparation. From these results it is possible to conclude that Echinochloa Colona starch could be used as a superdisintegrant.

In this work, modified-release solid dosage forms were fabricated by adjusting geometrical properties of solid dosage forms through hot-melt 3D extrusion (3D HME). Using a 3D printer with air pressure driving HME system, solid dosage forms containing ibuprofen (IBF), polyvinyl pyrrolidone (PVP), and polyethylene glycol (PEG) were printed by simultaneous HME and 3D deposition. Printed solid dosage forms were evaluated for their physicochemical properties, dissolution rates, and floatable behavior. Results revealed that IBF content in the solid dosage form could be individualized by adjusting the volume of solid dosage form. IBF was dispersed as amorphous state with enhanced solubility and dissolution rate in a polymer solid dosage form matrix. Due to absence of a disintegrant, sustained release of IBF from printed solid dosage forms was observed in phosphate buffer at pH 6.8. The dissolution rate of IBF was dependent on geometric properties of the solid dosage form. The dissolution rate of IBF could be modified by merging two different geometries into one solid dosage form. In this study, the 3D HME process showed high reproducibility and accuracy for preparing dosage forms. API dosage and release profile were found to be customizable by modifying or combining 3D modeling.

The article deals with the application of the system approach for constructing informationalgorithmic support for the pharmaceutical development of solid dosage forms. Information modeling of the life cycle of pharmaceutical drug development has been carried out starting from the stage of studying the active pharmaceutical substance and ending with the utilization of the drug. These models are built in the IDEF0 nomination. A generalized block diagram is presented that reflects, in its most general form, the iterative process of developing a ready-made dosage form as applied to the further transfer of technology. The basis of the system approach is QbD - "Quality planned in the development". To implement the QbD principle on the basis of the system approach, systemic set-theoretic models of information support of pharmaceutical development in the nomenclature of Melentiev have been constructed. A model for controlling the pressing process is also provided, which takes into account all the technological stages in the development of a solid dosage form. Functional models in the IDEF0 nomenclature of the technological process are constructed from the preparation of premises, personnel and components of the dosage form to the stage of packing and packaging of the finished dosage form. The construction of an informational intellectual control system for pharmaceutical development has been considered in detail with particular attention paid to the construction of a database of medicinal and auxiliary substances using the example of solid dosage forms. In Melentiev's bracket notation, the database of auxiliary substances necessary for the design of a solid dosage form is filled. The "Entity-relationship" model and the relational model for the database of medicinal and auxiliary substances have been constructe

Currently, the pharmaceutical and healthcare industries are moving through a period of unparalleled change. Major multinational pharmaceutical companies are restructuring, consolidating, merging and more importantly critically assessing their competitiveness to ensure constant growth in an ever-more demanding market where the cost of developing novel products is continuously increasing. The pharmaceutical manufacturing processes currently in existence for the production of solid oral dosage forms are associated with significant disadvantages and in many instances provide many processing problems. Therefore, it is well accepted that there is an increasing need for alternative processes to dramatically improve powder processing, and more importantly to ensure that acceptable, reproducible solid dosage forms can be manufactured. Consequently, pharmaceutical companies are beginning to invest in innovative processes capable of producing solid dosage forms that better meet the needs of the patient while providing efficient manufacturing operations. This article discusses two emerging solid dosage form manufacturing technologies, namely hot-melt extrusion and fluidized hot-melt granulation.

Background: Medicines reuse, the idea of re-dispensing returned medicines to others following quality control, is yet to be implemented in the UK. This practice is potentially a sustainable way of dealing with returned medicines, which are otherwise classed as medication waste and destroyed. To inch towards medicines reuse, it is important to know more about the different therapeutic classes and dosage forms that make up medication waste. For example, it is helpful to know if medicines being returned are mostly solid-dosage forms and thus have the potential to be reused or are from therapeutic classes that would make medicines reuse cost-effective. Little is known about the therapeutic classes and the dosage forms of wasted medicines. This study aimed to narratively review and report findings from the international literature on the different therapeutic classes and the dosage forms of medicines that are returned by patients to community pharmacies, hospitals, general practitioners’ clinics, or collected through waste campaigns. Studies based on surveys without physically returning medicines were also included where relevant. Methods: A comprehensive electronic search of databases, including PubMed and Google Scholar, was carried out over one month in 2017 and updated by 5 November 2020, using a combination of carefully created keywords. Results: Forty-five studies published in English between 2002 and 2020, comprising data from 26 countries were included and reviewed. Oral solid dosage forms (mostly tablets) were the commonly reported dosage form of all wasted medicines in 14 studies out of the 22 studies (64%) that described the dosage form, with percentages ranging from 40.6% to 95.6% of all wasted medicines. Although there was variability among the levels of medication waste reported in different countries, findings from the UK and Ethiopia were relatively consistent; in these, medicines for the cardiovascular system and anti-infective medicines, respectively, were the most common therapeutic classes for medication waste. Conclusion: This narrative review provides insights about the different therapeutic classes and dosage forms of medication waste either returned by patients, collected through waste campaigns, or indicated in survey responses. The findings could help policy makers understand the potential implications of treating most unused medicines as medication waste and whether therefore pursuing a medicines reuse scheme could be environmentally or financially logical. The quality and the safety of these returned medicines using criteria related to the storage conditions (such as heat and humidity), physical shape (such as being sealed, unopened, unused, and in blister packaging), and tampering are other important considerations for a medicines reuse scheme.

The occurrence of superficial wounds remains one of the most significant problems all the time among different types of household injuries. Up to 40 % persons annually have such damages of the skin like abrasions, scratches, cracks, suppurations, cuts, bedsores, and others. The problem of choosing a suitable drug arises acutely, since most pharmacists consider the issue of treatment by themselves. Patient’s referral to hospital departments for doctors advise remains minimal. Pharmacy specialists carry out pharmaceutical care and perform a personal analysis due to the given initial information about the mechanism, place of occur, size of wound and stage of the process of wound healing. Considering previous experience in fulfilling customer needs, they select optimal remedy, determine the majority of choice and thus, may be identified as the sales leaders. As for January 2021, the range of topical drugs used for the treatment of wounds numbered 270 trade names according to the State registry of medicines of Ukraine. They included 62 types of active pharmaceutical ingredients. Antimicrobial (antiseptic), anti-inflammatory, decongestant, protective and emollient action properties are underlined in their pharmaceutical inserts. It is similar for most of the medicines that are available on the Ukrainian pharmaceutical market. After all, their effectiveness to satisfy a patient need is as different as the price point. The choice of the optimal in composition and rational in the dosage form causes certain difficulties among the available wide range of medicines. Registrated semi-solid wound-healing drugs are represented by three groups of ATC classification: D03 – drugs for wounds and ulcers, D06 – antibiotics and chemotherapeutic drugs for use in dermatology, D08 – antiseptic and disinfectant drugs (table 1). Ointments predominate among semi-solid dosage forms with range 67.3 %, creams  –26.5 %, gels – 10.2 %, liniments – 6.1 %, and jellies only 2.0 % of the market. 59.2 % of semi-solid wound-healing drugs are produced by domestic enterprises, and 40.8 % – by foreign manufacturers. The recommendations for the use of semi-solid drugs were distributed as follows: for the first phase of wound process – 48.9 %, for the first and second phases – 12.2 %, for the second phase – 10.2 %, for the second and third phases – 26.4 %, for the third phase – 2.0 %. The article summarizes the results of a questionnaire of pharmaceutical specialists on the available and free sale wound-healing medicines among registered on the Ukrainian market, that are most promoted and recommended. The purpose of our work was to single out available and free sale wound-healing medicines among registered on the Ukrainian market, that are most promoted and recommended by pharmaceutical specialists. This would help to highlight the real picture of sales, to analyze the components of leading products and, as a result of additional research, to propose a model for the complex pharmaceutical development of a new wound-healing medicine in a rational dosage form with safe and effective active ingredients of plant origin, and, consequently, competitive for pharmaceutical manufacturers. The list of registered medicines was composed in accordance with the data from the State Register of Medicines of Ukraine (registrated trade names). The total number of respondents was 176. Questionnaire survey was the main method of information’s collecting: 46 respondents were interviewed individually, 130 persons of the target audience – by electronic form. Questionnaire contained the same questions for the individual survey and online one. Questionnaire contained particular situational tasks and questions related to the practical experience of the pharmaceutical specialists: 12 questions, among which 5 questions provided an answer in detail. Whole data was analyzed systematically and statistically. 342 reviews on 36 medicines trade names were received while answering the question about the drug’s recommendation for quick healing of abrasions and scratches. Various drugs promoting rapid injury healing («Bepanten®» ointment, «Levomekol» ointment, «Pantestin-Darnitsa®» gel and «Riativnyk®» cream) determined in the most mentioned requests. We found out that most pharmaceutical specialists chose semi-solid dosage forms containing dexpanthenol for light burn wounds healing («Bepanten®» cream and ointment, «D-panthenol», «Pantecream», «Pantexol-Jadran», «HepiDerm-Zdorovye»). Pharmaceutical specialists recommend «Contractubex®» and «Solcoseryl» mostly to improve wound healing and minimizing the development of a cosmetic scar. Only 1/3 of respondents would recommend to a pharmacy visitor to exam skin defect by doctor or cosmetician and get reliable advice. The recommendations of pharmaceutical specialists for shallow cuts were predominantly determined by antiseptic drugs – most of them chose iodine solutions. 264 reviews were received for 32 trade names of medicines as effective treatment for bedsores. Respondents preferred zinc oxide preparations usage. According to the investigation, the opinions of the interviewed pharmaceutical specialists were focused on the semi-solid dosage forms (ointments, creams etc) for various wound care (abrasions and scratches, burns, scars, bedsores). Dosage forms of medicines for the treatment of cut wounds were an exception. Solutions and new kind of plasters – Skin glue, were the drugs of choice in this group. Phytomedicines practically did not appear among the respondents answers.

Nowadays, novel fast dissolving oral films (FDF) have come in existence as an alternative dosage form in comparison with tablet, capsules, syrup and other oral dosage forms with respect to patient convenience and compliance. Fast dissolving oral films are helpful to paediatric and geriatric patients who experience difficulties in swallowing traditional oral solid-dosage forms. The FDF drug delivery systems are solid dosage form which disintegrate or dissolve within seconds when placed in the mouth cavity without need of water or chewing. FDF provide better drug dissolution, faster onset of action, bypassing the first pass metabolism of drugs and thus enhance their oral bioavailability with reduced dosing frequency. These formulations are suitable for cough, cold, sore throat, allergenic conditions, nausea, pain, hypertension and CNS disorders. The present review provides the details about the recent advancement in design and development of oral fast dissolving film.

Fast dissolving tablets is one of the most widely accepted dosage forms and also most popular dosage form, especially for pediatric patients because of incomplete development of the muscular and nervous system and a case of geriatric patients suffering from Parkinson’s disorder or hand tremors. Some solid dosage forms like tablets and capsules are present days facing the problems like difficulty in swallowing (dysphagia), resulting in many incidences of non-compliance and making the therapy ineffective. Oral dosage form and oral route are the most preferred route of administration for various drugs have limitations like the first-pass metabolism. Fast dissolving tablets are one of them. FDT have benefits such as accurate dosing, easy portability and manufacturing, good physical and chemical stability and an ideal alternative for pediatric and geriatric patients. Some tablets are designed to dissolve fastly in saliva, within a few seconds, and are true fast-dissolving tablets. Others contain agents to enhance the rate of tablet disintegration in the oral cavity and are more appropriately termed fast-disintegrating tablets, as they may take up to a minute to completely disintegrate.
