The range of doxycycline drugs on the pharmaceutical market of the Ukraine is very limited and is represented by solid forms (capsules and tablets) while a rapid effect and maximum bioavailability of the drug can be provided by parenteral administration. The object of the study is the drug doxycycline hyclate in the form of lyophilisate to prepare solution for injections. During the development of the drug it was taken into account that aqueous doxycycline solution is pH dependent and tends to shift the solution pH during long-term storage. Therefore, excipients such as stabilizer and antioxidant providing buffering properties and stability of the solution were introduced into the composition. According to the research results an optimal composition of lyophilized powder was selected, the production technology with the stage of solution treatment with activated carbon was developed which allowed to obtain lyophilized powder with a well-formed porous mass without splits, cracks and fissures, resistant to shaking, and the prepared solution for parenteral administration is stable by the «Degree of coloration» quality indicator during accelerated storage regimen. It was found that doxycycline hyclate in the form of a lyophilisate shows a wide range of antibacterial activity. Comparative studies in vitro for two drugs, in the form of lyophilisate with doxycycline hyclate for injections and hard gelatin capsules with 100 mg of doxycycline hyclate, confirm equivalence of their bacteriostatic action against bacteria causing infectious diseases in humans.
乌克兰药品市场上多西环素药物的范围非常有限,以固体形式(胶囊和片剂)为代表,而通过肠外给药可以提供药物的快速效果和最大的生物利用度。本研究的对象是将盐酸强力霉素以冻干液的形式制备注射用溶液。在药物的开发过程中,考虑到多西环素水溶液是pH依赖性的,并且在长期储存过程中倾向于改变溶液的pH值。因此,辅料,如稳定剂和抗氧化剂提供缓冲性能和稳定性的溶液被引入到组合物。根据研究结果,选择了冻干粉的最佳配方,开发了活性炭固溶阶段的生产工艺,使冻干粉具有孔隙结构良好、无裂开、裂纹和裂隙、耐震动的特点,制备的肠外给药液在加速贮藏过程中以“着色度”质量指标稳定。研究发现,冻干剂形式的多西环素水合物具有广泛的抗菌活性。两种药物的体外比较研究证实了它们对引起人类传染病的细菌的抑菌作用是等效的,这两种药物分别是注射用冻干液和100毫克水合强力霉素硬明胶胶囊。

The aim of the research is to study communicative tolerance of students of the Pharmaceutical Faculty of VSMU and analyze its dynamical characteristics. When comparing the degree of communicative tolerance for the 1st, 2nd and 5th year students respectively, there is a tendency towards a decrease in high and low degree of communicative tolerance and an increase in its average degree. It suggests about positive influence of the educational process on the communicative competence formation of a future pharmacist. Students with a high level of scale indicators (low degree of communicative tolerance) should be within the view of teachers of the Faculty of Pedagogics and Psychology with the course of Retraining and Advanced Training Faculty, employees of the social and pedagogical and psychological services, curators of academic groups and tutors.

The article presents the results of determining anti-inflammatory activity of the spray based on ibuprofen and liquid wormwood extract. Anti-inflammatory activity was studied on the model of local acute carrageenan inflammation. As a result of the studies it was found that the increase in paw weight averaged 49,66% in the control group of rats, in the group of rats receiving the comparison drug «Ibuleve» - 11,26%. For the group of rats receiving combined composition and the same composition without ibuprofen, the average increase in paw weight was 7,11% and 15,07%, respectively. The index of inflammatory inhibition when using combined composition was 85,68%, the composition with liquid extract of wormwood without ibuprofen was 69,65%, the liquid extract of wormwood 1:1 was 53,00%. The index of edema suppression proves that combined composition of the spray containing ibuprofen and liquid extract of wormwood has the most pronounced anti-inflammatory effect, for which the percentage of edema suppression exceeds the value for the comparison drug on the average by 8,36%.

PROBLEMS OF MAKING QUALITY ASSURANCE DOCUMENTATION 制作质量保证文件的问题
Pub Date : 2021-09-30 DOI: 10.52540/2074-9457.2021.3.5
E. Alexandrova
The article is devoted to the development of quality system documents for the pharmacy organization. The legislation of the Republic of Belarus, as well as the Eurasian Economic Union, requires the development and maintenance of the quality assurance system, the quality management system, the pharmaceutical quality system in a pharmacy organization, a distributor or manufacturer of medicinal products. The article presents the comparative analysis of regulatory requirements as well as approaches of the international standards ISO series to the construction of the quality systems and processes documentation. Such documents as the Quality Manual or its equivalent, Standard Operating Procedures (SOP) and Process Instructions are the most difficult to develop. The distribution of responsibility for processes within the organization is difficult to understand. On the example of RUE «BELPHARMATSIYA» it is shown how the processes in the pharmacy organization can be documented and responsibility for their implementation can be stated. The functioning of the quality system depends on the clarity of the documentation structure and its development and circulation organization. It is the responsibility of the organization authorities to maintain effective functioning of this system.
本文探讨了医药企业质量体系文件的编制。白俄罗斯共和国的立法,以及欧亚经济联盟,要求发展和维护质量保证体系,质量管理体系,制药组织,药品分销商或制造商的药品质量体系。本文介绍了法规要求的比较分析,以及国际标准ISO系列对质量体系和过程文件建设的方法。诸如质量手册或其等同文件、标准操作程序(SOP)和过程指导书等文件是最难制定的。组织中过程的责任分配是很难理解的。以RUE«BELPHARMATSIYA»为例,展示了如何记录药房组织的流程并说明其实施的责任。质量体系的运作取决于文件结构及其发展和流通组织的清晰度。组织当局有责任保持这一系统的有效运作。

The purpose of this work was to develop a device and technique for determining the soil trophiсity using the electrophysical method based on the measurement of the soil specific resistivity (SR). In the proposed device the F. Wenner installation is used as a sensor. The device has a modular design and includes a voltage boosting module, a PWM generator of rectangular pulses, a rectangular signal inverter and an H-bridge that switches the polarity of the power supply in order to prevent polarization of the electrodes. The metrological characteristics of the specific resistivity measurement as well as the influence of the electrodes immersion depth in the substrate studied are determined. Its significant influence and nonlinear character which was well approximated by the power function were established. The simplest equations for bringing the measured values of the RS to a certain depth of the electrodes in the object studied are proposed.

The article is devoted to the nomenclature analysis of medicines prepared at 21 pharmacies of the 1st category of RUE «BELPHARMATSIYA», the largest state pharmacy network in Minsk. Medicines preparation at pharmacies is carried out according to the doctors’ prescriptions and the requirements (applications) of healthcare organizations as well as in the form of intra-pharmacy stocking and packing. The main tasks of pharmacy preparation are: providing the population and healthcare organizations with dosage forms not manufactured by industry, preparation of dosage forms mainly used in pediatric and geriatric practice, individual pharmacotherapy provision. Pharmacists make from 38 to 174 dosage forms in one day. The nomenclature of the medicines prepared numbers 392most common prescriptions of which 47,2% prescriptions are unique: they were prepared by one pharmacy only. The most prevalent (42,8%) is preparation of complex in composition dosage forms which contain at least 4 ingredients. Therefore, there is an urgent question about the stability of dosage forms and shelf life detection (currently, the legislation hasn’t established shelf life of medicines prepared at pharmacy). The assortment of active ingredients and excipients has been analyzed. There are cases of medicines preparation from industrial medicines. The need for almost 100 names of active ingredients has been established. Nomenclature analysis of the prescriptions has confirmed the importance of medicines preparation development at a pharmacy to provide the population with medicines.
本文致力于对明斯克最大的国家药房网络RUE«BELPHARMATSIYA»第一类的21家药房制备的药物进行命名分析。药房的药物配制是根据医生的处方和保健组织的要求(申请)以及以药房内储存和包装的形式进行的。药学制剂的主要任务是:为人群和医疗机构提供非工业生产的剂型,制备主要用于儿科和老年实践的剂型,提供个体药物治疗。药剂师在一天内制作38到174种剂型。所制备药物的名称编号为392个最常见的处方,其中47.2%的处方是唯一的:它们仅由一家药房配制。最普遍的(42,8%)是制备含有至少4种成分的组合物剂型。因此,剂型的稳定性和保质期的检测是一个迫切的问题(目前,立法还没有对药房制备的药品的保质期进行规定)。分析了活性成分和赋形剂的分类。也有用工业药品配制药物的情况。已经确定需要将近100种活性成分的名称。对处方的命名法分析证实了药房的药物制剂开发对向人口提供药物的重要性。

The article is devoted to the assortment analysis of 5-aminosalicylic acid drugs used for the treatment of mild and moderate ulcerative colitis. A brief description of dosage forms for oral and rectal administration used for the treatment of this disease is given. It is shown that therapeutic efficacy of the drug is associated with the concentration of the active substance in the large intestine. Therefore, in order to increase its effectiveness it is important to use such dosage forms that would help to prevent and reduce mesalazine absorption in the proximal small intestine and contribute to maximum release in the large intestine. It is shown that the rectal suspension of mesalazine, which is a first-line drug and is included in the list of essential medicines, is not produced in the Republic of Belarus. Special attention is paid to the possibility of expanding the range of mesalazine drugs if there is a possibility of extemporal suspension production from tablets presented in the assortment including a domestic manufacturer.
本文对治疗轻、中度溃疡性结肠炎的5-氨基水杨酸类药物进行分类分析。简要说明用于治疗这种疾病的口服和直肠给药的剂型。结果表明,药物的治疗效果与大肠内活性物质的浓度有关。因此,为了提高其有效性,重要的是使用这样的剂型,将有助于防止和减少美沙拉嗪在小肠近端吸收,并有助于最大限度地释放在大肠。报告显示,白俄罗斯共和国不生产美沙拉嗪直肠悬浊液,这是一种一线药物,被列入基本药物清单。特别注意的是,如果有可能从包括国内制造商在内的分类中提供的片剂进行临时悬浮剂生产,则扩大美沙拉嗪药物范围的可能性。

One of the methods for treating oncological diseases is application of short-lived radionuclides. Existing risks of intoxication and radioactive contamination can be eliminated by introduction of a short-lived radon isotope into a hard strong fullerene coat. To increase the effectiveness of these drugs it is promising to introduce structural fragments of amino acids, peptides, steroid hormones, nucleic bases or heterocyclic compounds being able to accumulate exactly in tumoral but not in healthy tissues of the body. The article presents data on quantum-chemical simulation of electronic structure and thermodynamic stability of fullerenol radon-containing agents of radionuclide therapy on the example of a model cortisonefullerenol bioconjugate.
短寿命放射性核素的应用是治疗肿瘤疾病的方法之一。现有的中毒和放射性污染风险可以通过在坚硬的强富勒烯涂层中加入一种短寿命的氡同位素来消除。为了提高这些药物的有效性,有希望引入氨基酸、多肽、类固醇激素、核酸基或杂环化合物的结构片段,这些结构片段能够在肿瘤中而不是在身体的健康组织中积累。本文以皮质酮-富勒烯醇生物偶联物模型为例,介绍了含富勒烯醇放射性核素治疗剂的电子结构和热力学稳定性的量子化学模拟数据。

The purpose of this work was to study foreign experience in pharmacy manufacture and quality control of medicinal preparations (MP). Scientific literature and internet sources analysis, the author's own observations from 2005 to 2020 were made. It has been established that pharmacy manufacture of MPs abroad is carried out for the special needs of patients when pharmaceutical industry cannot produce them for various reasons. There are various approaches to standardization of the number of manufacturing pharmacies abroad: from complete prohibition of pharmacy manufacture of medicinal preparations in Portugal to mandatory license requirement in Austria and Germany. To manufacture medicinal preparations at a pharmacy the laboratory is established where necessary equipment, inventory, pharmaceutical substances and excipients are placed and the technological process is carried out. Pharmacy manufacture of sterile medicinal preparations is conducted under aseptic conditions in a specially equipped room or in a laminar-airflow cabinet. MPs must not be registered in most countries of the world. In the US and the European Union (EU) medicinal preparations are classified into medicines for immediate use and for prolonged storage. Expiration date must be stated for prolonged storage medicinal preparations, a dossier is made for them in the EU pharmacies. Pharmacies in most countries of the world manufacture medicinal preparations from tablets and capsules. Much attention abroad is given to ensure the quality of pharmacy manufacture of medicinal preparations: in the US, pharmacy manufacture of medicinal preparations is carried out in accordance with the requirements of Pharmacopoeia, in the EU according to the EU Council Resolution. A number of countries have developed guidelines or standard operational procedures for pharmacy manufacture of medicinal preparations. Constant training and assessment of employees’ competencies engaged in pharmacy manufacture of medicinal preparations is performed.
本工作的目的是研究国外中药制剂生产和质量控制的经验。通过对科学文献和网络资料的分析,对2005年至2020年笔者本人的观察结果进行了分析。已经确定,当制药工业由于各种原因无法生产时,国外制药生产MPs是为了满足患者的特殊需要。国外有各种标准化生产药房数量的方法:从葡萄牙完全禁止药品制剂的药房生产到奥地利和德国的强制许可要求。为了在药房生产制剂,必须建立实验室,放置必要的设备、库存、原料药和辅料,并执行工艺流程。无菌制剂的制药生产是在无菌条件下在专门配备的房间或层流柜中进行的。在世界上大多数国家,国会议员不得注册。在美国和欧盟(EU),药物制剂分为立即使用的药物和长期储存的药物。对于长期储存的药物制剂,必须说明有效期,并在欧盟药房为其制作档案。世界上大多数国家的药房都生产片剂和胶囊制剂。国外非常重视药物制剂的药学生产质量:在美国,药物制剂的药学生产按照药典的要求进行,在欧盟根据欧盟理事会决议进行。许多国家制定了药物制剂药学生产的准则或标准操作程序。对从事药物制剂生产的员工的能力进行持续培训和评估。
