The Moment

currently, omeprazole pellets are one of the most common pellet formulations on the pharmaceutical market of Ukraine (Gorobets, Matyash, Pekhenko & Barna, 2019). This medication is available in capsule form. Pellets are multi particular dosage forms that have several advantages over monoparticular dosage forms; therefore, pellets are promising oral delivery systems for active pharmaceutical ingredients (APIs). Pellets are used when the stability of the active substance changes with fluctuations in the pH of the environment, when irritation of the gastric mucosa is possible, to facilitate swallowing (especially important for patients with dysphagia, elderly patients, and children). When using polymers in the shell, it is possible to regulate the release in a certain part of the gastrointestinal tract, this allows you to get a point pharmacological effect. In addition, pellets can be of different sizes (from 0.1 to 2 mm), because of their shape, pellets exhibit abrasion resistance and are more fluid. Omeprazole is a synthetic substance. The active ingredient suppresses gastric acid secretion. In refers to the pharmaceutical group of proton pump inhibitors, it prescribes drugs in this group to treat active duodenal ulcers, gastric ulcers, gastro-oesophageal reflux disease (GERD), severe erosive esophagitis, pathological hypersecretory conditions, for example, Zollinger Ellison syndrome. Among the most commonly used methods for the production of pellets are: stage-by-stage spraying of solutions or suspensions (the second name is stage-by-stage layering); direct pelletization (the second name is extrusion-spheronization); spray drying and spray cooling of melts; agglomeration-spheronization. Unfortunately, at the moment, none of the Ukrainian manufacturers is manufactured enteric pellets on their own (they buy ready-made pellets), while there are medicines of both foreign and Ukrainian origin on the domestic market. The article contains an overview of pharmaceutical preparations as pellets, systematization of information on production methods, a review of omeprazole drugs as pellets, presented on the pharmaceutical market of Ukraine. The purpose of this study was to summarize the cases when the use of such a form as pellets is the most reasonable; make an overview of medicines in Ukraine containing pellets; summarize modern methods of pellet production.

Sole Criterion

To improve the immediate results of surgical treatment of patients with perforated gastroduodenal ulcers using minimally invasive correction and an integrated treatment. The results of 253 patients with perforated gastroduodenal ulcers who were treated from 2013 to 2018 were analyzed. Chronic ulcers were found in 82 (32%) cases among all gastric ulcers, acute ones constituted 42 (16%) cases. Chronic duodenal ulcers reached 94 (37%), acute ones constituted 35 (14%). The diagnostic laparoscopy was performed in 13 (5%) patients, in 8 (3%) patients the perforated hole was sutured laparoscopically and in 5 (2%) patients the conversion was performed. Abdominocentesis with preoperative abdominal cavity drainage was carried out in 45(18%) patients. Through this drainage after exudate evacuation 200 ml of dekasan solution was injected. In 119 cultures of abdominal exudates with determinate pathogenic microflora Enterococcus faecalis dominated - 31 patients (26%). Among the postoperative complications the failure of intestinal sutures was observed in 4 (1.5%) patients. Postoperative mortality was 11.5%. Progression of multiple organ failure became the cause of mortality in 17 (59%) patients. Thus, the time from the moment of perforation till the moment of surgery must not be the sole criterion in the choice of method of operative intervention, and it is insufficient as an absolute indicator for the possibility of the radical surgical procedures (gastric resection). Undoubtedly laparoscopic suturing of the perforated gastroduodenal ulcer has advantages over laparotomy.

The Stability

Background. Extemporaneous compounding is a pharmacy practice to produce suitable pharmaceutical preparations when there are no commercially available, licensed, and age-specific dosage forms. Compared to the use of authorized drugs, these preparations have significant risks. Stability issues are one of the major concerns during the preparation of extemporaneous formulations. Aim. The aim of this work was to study the stability of pediatric extemporaneous formulations of commercially available conventional solid dosage forms by reviewing systematically the currently available stability studies. Method. Articles were searched in the databases of the Web of Science, PubMed, Scopus, EMBASE, Cochrane Library, and Google Scholar. From all the searched articles, a total of 28 experimental studies reporting the stability of oral pediatric extemporaneous formulations were included based on the inclusion criteria. Oral extemporaneous formulations from commercially available dosage forms and pure drugs were considered. According to the United States and British Pharmacopeia (USP and BP), most extemporaneous formulations are accepted as chemically stable if they maintain ≥90% of the original drug amount, physically stable if there is no apparent change in physical property, and microbiologically stable if there is no growth of microorganisms in prepared formulations. Finding. In this study, most extemporaneous pediatric oral formulations were chemically, physically, and microbiologically stable and retained more than 90% of the initial content. Very few studies did not include either a physical stability test or a microbiological stability test. Conclusion. According to this systematic review, the chemical and physical instabilities as well as microbial growth on pediatric oral extemporaneous formulations are very rare in published experimental studies. Most studies show that extemporaneous preparations are stable at the ICH recommended storage conditions and duration. Generally, extemporaneously prepared oral formulations will be the promising option for child medications.

Burst Release

: Alzheimer's disease (AD) is usually caused intellectual deterioration which happened due to the degeneration of cholinergic neurons. Donepezil is employed for cholinesterase enzyme Inhibition (ChEI) to treat AD in a wider population. Over the years, researchers finding difficulties prompted through traditional dosage forms particularly in geriatric patience. To avoid swallowing difficulties brought about with the aid of the AD population, researchers majorly focused on oral thin-film technology (OTF). This technology strongly eliminates issues caused by solid oral dosage forms. It is one of the quality strategies to an alternate drug that is used in the first-pass metabolism or pre systematic metabolism. The solubility of the drug is a higher trouble and it can expand by way of lowering particle size. Nanofibers are the excellent desire to minimize the drug particles to the submicron stage and can increase the drug release rate drastically. It can be prepared by Electrospinning technology by incorporating polymeric material into poorly soluble drugs. Mostly natural and biodegradable polymers prefer in all pharmaceutical preparations. Polymers employed for oral delivery should be stable, possess mucoadhesive property, and should release the drug by diffusion, degradation, and swelling mechanism. The objective of the present review explains various thin-film and nanofiber formulations used for faster drug release in the treatment of Alzheimer's disease.

A simple, rapid and sensitive spectrophotmetric method for trace determination of salbutamol (SAL) in aqueous solution and in pharmaceutical preparations is described. The method is based on the diazotization coupling reaction of the intended compound with 4-amino benzoic acid (ABA) in alkaline medium to form an intense orange, water soluble dye that is stable and shows maximum absorption at 410 nm. A graph of absorbance versus concentration indicates that Beer’s law is obeyed over the concentration range of 0.5-30 ppm, with a molar absorbtivity 3.76×104 L.mol-1 .cm-1 depending on the concentration of SAL. The optimum conditions and stability of the colored product have been investigated and the method was applied successfully to the determination of SAL in dosage forms.

Analysis of the assortment of sedatives registered in the Republic of Uzbekistan showed that sedatives are represented on the pharmaceutical market of the country by such dosage forms as drops, solutions, tinctures, syrups, medicinal herbal raw materials, capsules and tablets. Considering that sedatives registered in the form of a substance, with the exception of the dry extract of Leoglycyrfl produced by “Uzkimyofarm”, there are practically no names of S.K. Islambekov in the Joint Stock Company. In this regard, we consider it expedient to create a new sedative medicinal product of herbal origin in the form of a substance and obtain dosage forms based on it.

A description of development in the utilization pattern of cimetidine (Tagamet) in Denmark is given on the basis of 19 154 granted applications for individual drug reimbursement submitted to the National Board of Health from the initial registration of cimetidine in September 1977 until general reimbursement was introduced in July 1981. The application rate per 100000 inhabitants increased steeply from 49 in 1978 to 148 in 1980 and decreased to 127 in 1981. Despite this rapid introduction, however, hospital utilization for ulcer disease was constant during this period. Half of the applications treated diagnosed duodenal ulcers and a third gastric ulcers. Only 50% of those gastric ulcers were diagnosed by endoscopy. The age-specific application rate reached a peak in the age group of 50–69 years. There was a considerable geographical variation in the rate of application. The reason for this is unknown, since the variations in the ages of patients and years of application were different in different counties, and no correlation between application rate and proxy variables for standard of health and special interest in ulcer disease between the different counties could be shown.

BACKGROUND/OBJECTIVES: As recently as 40 years ago, a decline in the incidence of peptic ulcers was observed. The discovery of Helicobacter pylori had a further major impact on the incidence of ulcer disease. Our aim was to evaluate the trends in the incidence and bleeding complications of ulcer disease in the Netherlands.METHODS: From a computerized endoscopy database of a district hospital, the data of all patients who underwent upper gastrointestinal endoscopy from 1996 to 2005 were analyzed. The incidence of duodenal and gastric ulcers, with and without complications, were compared over time.RESULTS: Overall, 20,006 upper gastrointestinal endoscopies were performed. Duodenal ulcers were diagnosed in 696 (3.5%) cases, with signs of bleeding in 158 (22.7%). Forty-five (6.5%) of these ulcers were classified as Forrest I and 113 (16.2%) as Forrest II. Gastric ulcers were diagnosed in 487 cases (2.4%), with signs of bleeding in 60 (12.3%). A Forrest 1 designation was diagnosed in 19 patients (3.9%) and Forrest 2 in 41 patients (8.4%). The incidence of gastric ulcers was stable over time, while the incidence of duodenal ulcers declined.CONCLUSIONS: The incidence of duodenal ulcer disease in the Dutch population is steadily decreasing over time. Test and treatment regimens for H pylori have possibly contributed to this decline. With a further decline in the prevalence of H pylori, the incidence of gastric ulcers is likely to exceed the incidence of duodenal ulcers in the very near future, revisiting a similar situation that was present at the beginning of the previous century.

AbstractWe present a numerical method to solve the Vlasov-Poisson-Fokker-Planck (VPFP) system using the NRxx method proposed in [4, 7, 9]. A globally hyperbolic moment system similar to that in [23] is derived. In this system, the Fokker-Planck (FP) operator term is reduced into the linear combination of the moment coefficients, which can be solved analytically under proper truncation. The non-splitting method, which can keep mass conservation and the balance law of the total momentum, is used to solve the whole system. A numerical problem for the VPFP system with an analytic solution is presented to indicate the spectral convergence with the moment number and the linear convergence with the grid size. Two more numerical experiments are tested to demonstrate the stability and accuracy of the NRxx method when applied to the VPFP system.

Life Circle

There are many developed strategies in the emulsion stability evaluation, for purpose of determining the life circle of emulsions. Most of them are based on the reological properties of the emulsions. There are very few which relay on the direct emulsion observations. In this paper we present the developed method for the emulsion stability evaluation by the direct observation of optical properties. As the stability quantification measure we propose the fractal dimension approach. The method is based on the measure of the emulsion transmittance properties, which are directly dependent on the emulsion stability at the moment of measurement. As the test emulsion the oil in the water emulsion was used. The system is classified as the stable emulsion and our intention was to find the moment when the emulsion starts to break. The emulsion transmittance properties were measured using an acquisition system, consisting of a CCD camera and a fast PC configuration equipped with the capturing software. The fractal dimensions were determined by the so called box counting method. The experimental emulsions were measured continuously within the period of 1200 h, from the moment of the emulsion creation. The changes of fractal dimensions were observed which indicates that the emulsion changed its state and therefore the stability during the time. Three regions of the emulsion life circle were divided according to the fractal dimensions measurement, which can be connected with the stable, unstable, and meta-stable states of the emulsion life circle. In the end, the model of the emulsion behavior was developed for the purpose of quantifying the changes in the experimental emulsion.
