Heat damage is a widespread effect of the environment on humans, driven by global warming, military conflicts, technological disasters, work in hot environments, and engagement in extreme sports and tourism.</p> <p><strong>The aim</strong> of the study: to propose a model of acute HT in rats that does not cause the death of animals, to determine the dependence of thermoresistance on gender, and to compare the effectiveness of the thermoprotective effects of a range of non-steroidal anti-inflammatory drugs (NSAIDs), paracetamol, and glucosamine hydrochloride in this model.</p> <p><strong>Materials and Methods:</strong> The experiment was conducted on adult white rats of both genders. Acute HT was modelled by using a specially developed method involving heat exposure to animals at +55 °C for 30 minutes, followed by a recovery period of 60 minutes. Rectal temperature was measured every 15 minutes. The degree of hyperthermia in males and females was determined. The presence and intensity of the thermoprotective effect of glucosamine hydrochloride (G h/ch), diclofenac sodium, acetylsalicylic acid (ASA), nimesulide, etoricoxib, celecoxib, and paracetamol were evaluated through intragastric administration 60 minutes before heat exposure. The results were analyzed using the STATISTICA 12.0 program.</p> <p><strong>Results:</strong> It was established that heat exposure at +55 °C for 30 minutes effectively replicates acute HT in rats without causing animal fatalities, adhering to bioethical requirements. Body temperature increases by 10-13 %, characterized as a heat stroke. Occasionally, thermoresistant animals are encountered, where the temperature increase during the first 15 minutes of exposure is less than 1 °C. These animals should not be used for further modelling of heat trauma. Male rats are more sensitive to the effect of high environmental temperatures than females, exhibiting greater hyperthermia (temperature increase of 5.03±0.39°C compared to 3.72±0.22 °C in females, p&lt;0.01). The thermoprotective effect of glucosamine hydrochloride depends on gender, being more pronounced in males. Among the 6 tested COX inhibitors, the most significant thermoprotective effect was observed in the highly selective COX-2 inhibitor celecoxib and the weakly selective central inhibitor paracetamol, warranting in-depth research into their impact on organ and system states following heat trauma, as well as the mechanisms of their thermoprotective action. The thermoprotective effect is not associated with selectivity towards COX (cyclooxygenase): it is not observed in the highly selective COX-2 inhibitor etoricoxib and moderately selective COX-2 inhibitor nimesulide, as well as in non-selective COX inhibitors such as diclofenac sodium and aspirin, which also slows down the recovery of body temperature after heat exposure.</p> <p><strong>Conclusions:</strong> A convenient and simple model of acute HT in rats is proposed, demonstrating higher thermosensitivity and a more pronounced thermoprotective effect of glucosamine hydrochloride in males. A significant thermoprotective effect was identified in celecoxib and paracetamol, surpassing other investigated NSAIDs. The mechanism and specific features of this effect require further clarification</p> Polina Chuykova Sergii Shtrygol’ Andrii Taran Tetiana Yudkevych Iryna Lebedinets Denys Oklei Copyright (c) 2024 Polina Chuykova, Sergii Shtrygol’, Andrii Taran, Tetiana Yudkevych, Iryna Lebedinets, Denys Oklei http://creativecommons.org/licenses/by/4.0 2024-04-30 2024-04-30 2 (48) 4 11 10.15587/2519-4852.2024.301620 Study of the degradation behavior of enisamium iodide, tilorone dihydrochloride, morpholinium thiazotate in the soil by the GC-Fid method https://journals.uran.ua/sr_pharm/article/view/300209 <p><strong>The aim.</strong> To study the behaviour of enisamium iodide, thiloron dihydrochloride, morpholinium thiazotate, and the suitability of the previously developed GC-FID methodology in soil.</p> <p><strong>Materials and methods.</strong> The determination of the Enisamium iodide, Tilorone dihydrochloride, and Morpholinium thiazotate in soil gas chromatography with a flame ionization detector using the Rxi-5 ms (30 m long, 0.25 mm outer diameter and 0.25 μm liquid stationary phase thickness).</p> <p><strong>Results.</strong> A study was conducted on the behaviour of enisamium iodide, thiloron dihydrochloride, and morpholinium thiazotate in soil, along with the assessment of the suitability of the developed GC-FID methodology for determination in soil.

In addition, today the relationship between dermatopathologies and the psychoemotional state of people and vice versa is clearly monitored. Psychodermatology is engaged in the study of exactly this regularity. One of the most common trichological diseases is androgenic alopecia, which is characterized by excessive hair loss under the influence of androgens in individuals with a hereditary predisposition. Androgenic alopecia is often accompanied by secondary mental disorders, which significantly impair the quality of people’s life. It is relevant to conduct sociological research of this problem among men of all age groups. Such research will reveal the level of influence of androgenic alopecia on the psychoemotional state of men who may be potential consumers of medicines and dermatocosmetics.</p> <p><strong>The </strong><strong>aim</strong><strong> of the work </strong>was to conduct a sociological study to establish the impact of androgenic alopecia on the psychoemotional state of men and their readiness for pharmacotherapy.</p> <p><strong>Materials and methods.</strong> Sociological research was conducted from 01.03.2019 to 31.08.2019 by surveying 150 men aged 18 to 66. Respondents were visitors to pharmacies in the Ivano-Frankivsk and Chernivtsi regions of Ukraine, who gave written consent to participate in the survey. Only persons with visible manifestations of androgenic alopecia according to the Norwood scale were included in the survey. All respondents were divided into the following age groups: from 18 to 20 years old, from 21 to 30 years old, from 31 to 40 years old, from 41 to 50 years old, from 51 to 60 years old, from 61 years old and older. The distribution was carried out to segment the target market. The results of the study were displayed as percentages with 95 % confidence intervals. Statistical analysis was performed using R version 4.1.2 (R Core Team (2021).</p> <p><strong>The results. </strong>According to the results of the sociological study, 48.7 % of interviewed men consider that androgenic alopecia is a problem which can affect the emotional state and, so, the quality of life. As a result, about 90 % of the respondents indicated that they need to expand the assortment of effective remedies to solve this problem on the pharmaceutical market of Ukraine, of which 36.7 % are ready to pay for a course of effective pharmacotherapy from 200 to 500 hryvnias.</p> <p><strong>Conclusions. </strong>The obtained results confirm that androgenic alopecia has a negative effect on the psychoemotional state of men and worsens their quality of life.

Ramipril (purity <a href="https://www.sigmaaldrich.com/UA/en/product/sigma/r0404">≥98 % (HPLC)</a>) was purchased from AARTI Industries Limited (India). Ramipril tablets 5 mg and 10 mg were purchased from a local pharmacy.</p> <p><strong>Results and discussion.</strong> Two spectrophotometric methods for the determination of ramipril in tablets have been developed. We have tested various sulfophthalein dyes (BPB, bromocresol green, bromthymol blue, thymol blue, CR) in order to choose the optimal for the method development. According to the results of the experimental studies, we chose BPB and CR as reagents, and the solvent was acetonitrile for both methods. The optimal conditions for the quantitative determination of ramipril in tabletsy using BPB were established: dye concentration - 2.35×10<sup>-4 </sup>mol/L, volume of BPB solution – 1.0 ml, without heating, wavelength – 598 nm, reaction time – 5 min, temperature of the solution – 25 °C. The optimal conditions for the quantitative determination of ramipril in tabletsusing CR were established: dye 1.33×10<sup>-4 </sup>mol/L, volume of CR solution – 1.0 ml, without heating, wavelength – 395 nm, reaction time – 5 min, temperature of the solution – 25 °C. The spectrophotometric method by using BPB was linear in the concentration range of 1.99-5.96 µg/mL, LOD – 0.20 µg/mL, LOQ – 0.60 µg/mL. The spectrophotometric method using CR was linear in the concentration range of 0.42-5.44 µg/mL, LOD – 0.10 µg/mL, and LOQ – 0.36 µg/mL. The results of the study on robustness, accuracy, and precision were within the acceptance criteria. The results of studying the «greenness» of both methods indicate an excellent «green» analysis.<strong>Conclusions.</strong> Developed methods can be used as an alternative method for the routine analysis of ramipril tablets</p> Kateryna Typlynska Mariana Horyn Tetyana Kucher Liubomyr Kryskiw Liliya Logoyda Copyright (c) 2024 Kateryna Typlynska, Mariana Horyn, Tetyana Kucher, Liubomyr Kryskiw, Liliya Logoyda http://creativecommons.org/licenses/by/4.0 2024-04-30 2024-04-30 2 (48) 44 52 10.15587/2519-4852.2024.302635 Formulation of mouth-dissolving tablets containing a spray-dried solid dispersion of poorly water-soluble fenoprofen calcium dihydrate and its characterization https://journals.uran.ua/sr_pharm/article/view/302788 <p><strong>The aim </strong>and objective of this investigation focus on the formulation of mouth-dissolving tablets of Fenoprofen calcium dihydrate spray dried solid dispersions.</p> <p><strong>Materials and methods. </strong>Spray drying is a well-recognized manufacturing technique that can be used to create amorphous solid dispersions, which are an effective delivery method for poorly water-soluble pharmaceuticals such as Fenoprofen calcium dihydrate (FCD). In addition to skimmed milk powder (SMP) and FCD, the carrier β-cyclodextrin was used to produce solid dispersions.</p> <p><strong>Results and discussion. </strong>The production of solid dispersions yielded reproducible results. Solid dispersion with β-cyclodextrin and skimmed milk powder is one way to increase disintegration time by increasing the water solubility of inadequately water-soluble FCD. In-vitro dissolution experiments of FCD mouth-dissolving tablets revealed significant differences. Stability studies should evaluate drug product characteristics that are susceptible to change during storage and are anticipated to impact quality, safety, and efficacy to demonstrate that the optimal formulations remain stable over the course of the study. The results of stability experiments were statistically significant at p&lt;0.05 using one-way ANOVA followed by Dunnet's test. During in-vivo anti-inflammatory experiments, the formulation SDC6 demonstrated a greater percentage of inhibition than the purified drug and super disintegrant, and the results were statistically significant using one-way ANOVA followed by the Bonferroni test.</p> <p><strong>Conclusions. </strong>The solid dispersions were prepared with β-cyclodextrin, and skimmed milk powder improved the solubility of the poorly water-soluble fenoprofen calcium dihydrate.

To improve the management of the PC's innovative activity, a methodology for determining the range of management decisions is proposed based on the results obtained in the framework of creating a report on the patent landscape.</p> <p><strong>Conclusions.</strong> In order to achieve the provision of effective and safe domestic drugs to the population of Ukraine, it is necessary to intensify research in the direction of the formation of an effective system of management of the innovative activity of pharmaceutical companies (PC), focused on their gradual transition to an innovative development model. The conducted analysis showed that despite a sufficiently large number of publications devoted to the problems of innovation management, issues related to the problem of forming an effective system of managing the innovative activity of PCs, as well as choosing an effective toolkit for evaluating and managing their innovative potential, taking into account the specifics of the flow of innovative processes in pharmacy, remain insufficiently disclosed and require further research. The proposed structural model of the innovative potential of the FC, a justified methodological toolkit for its assessment, as well as the construction of a cognitive map to determine the most appropriate key components and directions for further improvement and development of the innovative potential will contribute to increasing the efficiency of the innovative activities of enterprises and the implementation of the goals of the innovation strategy. The developed algorithm of preventive management of innovative activity of the PC, aimed at improving the quality of decisions made on innovation management thanks to the use of patent landscape tools, will also contribute to the faster entry into the market of domestically produced innovative medicinal products</p> Sanjay Kumar Nayak Olga Posilkina Olena Litvinova Copyright (c) 2024 Olga Posilkina, Sanjay Kumar Nayak, Olena Litvinova http://creativecommons.org/licenses/by/4.0 2024-04-30 2024-04-30 2 (48) 90 102 10.15587/2519-4852.2024.303060
