THE INFLUENCE OF LOW-MOLECULAR SUBSTANCES ON THE PHASE SEPARATION CAPACITY OF A TWO-PHASE PEG – SODIUM CITRATE – WATER SYSTEM

As is known, two-phase polymer-polymer-water and polymer-electrolyte-water systems (SPIS) are widely used in the separation and purification of biological objects in biotechnology and pharmacology, as well as in the quality control of medicinal products. Depending on the nature of these processes, it is important to purposefully change the separation capacity of SPIS. The aim of the presented research is to ensure that it is adapted to each application object by using different additives to separate and purify biological objects. The presented study investigated the phase diagrams of the water-polymer two-phase system PEG - sodium citrate - water in the presence of certain additives. The influence of additives on the separating ability of the two-phase system PEG - sodium citrate - water was determined. Analysis of the provided data shows that the variation in the parameters of the phase diagram and the different values of the separating ability n* of the two-phase system depending on the nature of the additives is associated with changes in the structure of water under the influence of these factors. This leads to changes in the interaction of the phase-forming components of the two-phase system with water, resulting in differences in the physicochemical properties, particularly the relative hydrophobicities of the two-phase system.

Combination of a solid phase extraction and a two-dimensional LC-UV method for the analysis of vitamin D3 and its isomers in olive oil

The current HPLC methods for the quantification of vitamin D3 (VitD3) and its two isomers previtamin D3 (PreVitD3) and trans-vitamin D3 (trans-VitD3) in olive oil preparations present some limitations mainly due to peak overlapping of the oily matrix components with the compounds of interest. The use of two-dimensional liquid chromatography (2D-LC) with different retention mechanism can reach higher resolving power thus allowing the analysis of complex samples.The present paper proposes a new alternative method including a solid phase extraction sample preparation step and a two-dimensional liquid chromatographic analysis using routine instrumentation, fitting the needs of quality assurance and quality control laboratories of pharmaceutical companies. The extraction protocol was demonstrated to provide a clean-up of the sample and a quantitative recovery of the species of interest. The 2D method proved its suitability in the isolation of vitamins from oil components in the first dimension and the separation and quantification of the analytes in the second dimension thanks to the orthogonal selectivities of phenyl and porous graphitic carbon (PGC) stationary phases.The method was validated following ICH guidelines and possesses an adequate sensitivity to quantify the impurity trans-VitD3 in pharmaceuticals considering the limits imposed by regulatory agencies. The applicability of the phenyl x PGC 2D-LC-UV method to quality control of medicinal products based on VitD3 in olive oil was confirmed by the successful quantification of vitamins in olive oil formulations.

ITS1 Barcode and Phytochemical Analysis by Gas Chromatography–Mass Spectrometry of Corynaea crassa Hook. f (Balanophoraceae) from Ecuador and Peru

The use of medicinal plants is the basis of traditional healthcare. Recently, the use of herbal medicine has been increasing among consumers due to availability, economy, and less side effect. For instance, the hemiparasite plant Corynaea crassa has medicinal properties and could be found in some regions of America, from Costa Rica to Bolivia. Phytochemical and genetic characterization of medicinal plants is needed for proper identification of metabolites responsible for medicinal properties and for genotyping, respectively. Moreover, characterization of medicinal plants through the use of DNA barcodes is an important tool for phylogenetic analysis and identification of species; furthermore, complemented with phytochemical analysis, both are useful for identification of plant species and quality control of medicinal products. The objective of this study was to analyze the species of C. crassa collected in Ecuador and Peru from the phylogenetic and phytochemical point of view. Polymerase chain reaction (PCR) was performed for amplification of the internal transcribed spacer 1 (ITS1) region after DNA extraction of samples of C. crassa. Blast analysis was performed in the GenBank database with the ITS1 sequences obtained from two accessions of C. crassa from Ecuador (GenBank accession numbers OM471920 and OM471919 for isolates CIBE-17 and CIBE-18, respectively) and three from Peru (GenBank accession numbers OM471921, OM471922, and OM471923 for isolates CIBE-13, CIBE-14, and CIBE-15, respectively). The accessions available in the GenBank were used for phylogenetic analysis. For the phytochemical analysis, hydroalcoholic extracts were obtained by maceration using 80% ethanol as solvent, followed by a derivatization process and analysis by gas chromatography-mass spectrometry. Based on the phylogenetic analysis of the C. crassa samples, the ITS1 sequence could be used to differentiate C. crassa of different locations. The samples of C. crassa from Ecuador and Peru are more similar between them than with other clades including Helosis spp. The phytochemical study revealed differences in the presence and relative abundance of some metabolites; mainly eugenol, 1,4-lactone arabinonic acid, dimethoxyrabelomycin and azelaic acid, which are reported for the first time for the species under study and the genus Corynaea. These results are the first findings on the combined analysis using genetic and phytochemical analysis for C. crassa, which could be used as a useful tool for quality control of the C. crassa species in medicinal products.

Background: Quality is one of the three main characteristics of medicinal products. The quality assurance process is multi-stage: during the manufacturing, quality control is the commitment of the manufacturer, but after medicinal products become part of the distribution and pharmacy network, analytical quality control is carried out within the program for Market Surveillance. There are different approaches in conducting quality control of medicinal products under the Market Surveillance Program. Aim: The aim of the study is to compare the results obtained under two approaches: individual testing and testing by groups with the same active substance. Methods: In this study, comparative tests for assay and purity were carried out within two groups of medicinal products from the antihypertensive group containing Amlodipine besilate and Valsartan. Analyses were performed in accordance with the available pharmacopoeial monographs, as well as those from literature sources. Results: The results from the assay tests show a significant difference in the same product tested. Analytical methods for the determination of impurities also show different results when analyzing the same medicinal product. Conclusion: Considering the performed analytical tests, the obtained results can be used to make several conclusions and suggestions concerning the optimisation of the Annual Market Surveillance Program.

Recommendations on Describing the Requirements for Microbiological Quality and Sterility of Medicinal Products

The paper presents recommendations on describing analytical procedures for evaluation of medicinal products in terms of sterility and microbiological quality in accordance with the State Pharmacopoeia of the Russian Federation and the Pharmacopoeia of the EAEU. These quality attributes should be covered in Product specification files for any medicinal product. The paper describes specific considerations for preparation of the corresponding sections of the Russian or EAEU Product specification files. It is necessary to provide and justify quality requirements, refer to or describe the recommended analytical procedure and indicate differences, if any, from the standard one. Standardisation of the approach to microbiological quality control of medicinal products will allow analysts to accurately perform the tests, get reliable results and ensure the safety of medicinal products.

NMR as Used in the Russian and Foreign Pharmacopoeias for Quality Control of Medicinal Products

The ongoing development of the Pharmacopoeia of the Eurasian Economic Union and the current trend for harmonisation of the Russian Pharmacopoeia with the world leading pharmacopoeias suggest the necessity of studying how different pharmacopoeias use nuclear magnetic resonance (NMR) for quality control of medicinal products. The aim of the study was to compare the extent of medicine quality characteristics assessed by NMR in the Russian and foreign pharmacopoeias. The review summarises the experience of various national and world pharmacopoeias in using the NMR method for quality control of medicines and certification of pharmacopoeial reference materials. The comparative analysis covered the following quality parameters: active ingredient identification, determination of the composition of non-stoichiometric compounds, determination of the average polymer chain length in polymers and block copolymers, determination of the absolute content of the active ingredient, identification and quantification of impurities, polymorphism, and crystallinity. It was shown that the United States and Japanese Pharmacopoeias are leading the way in introducing the NMR method into pharmacopoeial analysis. There have been some positive trends in the introduction of the NMR method in the State Pharmacopoeia of the Russian Federation as well. It was concluded that changes are needed in the general chapters “Nuclear Magnetic Resonance Spectroscopy” and “Reference Standards” of the State Pharmacopoeia of the Russian Federation, 14th ed. in order to harmonise the texts with those of the Eurasian Pharmacopoeia and the European Pharmacopoeia and to allow for the possibility of direct identification of a substance by complex analysis of NMR spectral data, without comparing the test sample and the reference standard spectra. The NMR method should be included in the list of absolute methods used for determination of purity of primary chemical reference substances during certification.

Limitations of NIR Spectrometry as an Identification Test for Active Ingredients in Medicinal Products

Near-infrared spectrometry (NIRS) is a new pharmacopoeial method. It is widely used in the pharmaceutical industry for quality control of medicinal products at various production stages (control of raw materials and finished products), and for detection of substandard and counterfeit drugs.The aim of the study was to assess the feasibility of using NIRS as an identification test for active ingredients during pre-marketing quality control of medicinal products.Materials and methods: 327 drugs samples represented as solid and semisolid dosage forms were tested by NIRS following their examination by well-established pharmacopoeial Identification methods during pre-marketing laboratory evaluation. The NIR spectra of the test samples were compared with the spectral library classification models.Results: NIRS confirmed the identity of 3.1% of the tested medicinal products. It was demonstrated that library classification models could be used for identification of only those medicines that were produced by a specific manufacturer, i.e. for confirmation of medicine identity.Conclusions: the NIRS method is unpractical as an Identification test for active ingredients in medicinal products during the pre-marketing laboratory evaluation stage. The main limitations of NIRS are lack of complete sets of library classification models for all medicinal products available in the market and non-reproducibility of spectral library data obtained with a different instrument.

Methodological Approaches to Determination of Depressor Substances in Medicinal Products

In order to harmonise national and foreign requirements for quality control of medicinal products, a second variant of the test method, which complies with the requirements of the European Pharmacopoeia, was included into the general monograph OFS.1.2.4.0008.18 “Test for depressor substances”. The aim of the study was to compare the two variants of the in vivo test method that uses cats for determination of depressor substances in medicinal products and to develop recommendations for the use of these two variants of the test method. The comparative analysis of the two ways of determining impurities that lower blood pressure revealed different approaches to performing the test and to testing an animal's sensitivity to the reference solution (histamine dihydrochloride). It was demonstrated that different concentrations, volumes, and doses of medicinal products are used to assess the results of testing performed by variants 1 and 2 of the test method according to the pharmacopoeial requirements. Based on the established differences in the methodological approach to determination of depressor substances in medicinal products, the authors developed recommendations for each of the test variants. The inclusion of two variants of the test method in the general monograph provides an opportunity to evaluate the quality of medicinal products under the most appropriate conditions and, consequently, to improve the validity of test results.

Quantitative determination of trifuzol in the 2.5% injection solution by spectrophotometric method

The effectiveness of the treatment of common diseases of the respiratory system, hematopoietic system, digestive system of livestock and domestic animals with the help of existing drugs is not always sufficient, and there is an urgent need to expand the arsenal of domestic veterinary medicinal products that would exhibit antiviral, anti-inflammatory and low toxicity, prompted to search, create and improve existing veterinary medicines.
 A medicine in the form of a 2.5% injection solution containing, as an active substance, a 1,2,4-triazole derivative – piperidine 2-[5-(furan-2-yl)-4-phenyl-1,2,4-triazole-3-ylthio] acetate exhibits a fairly high level of anti-inflammatory, antiviral, and immunomodulating effects. The arsenal of domestic veterinary drugs with the above activity is currently limited.
 The analysis of veterinary medicinal products is the most important stage in the system for ensuring the quality control of medicinal products.
 During the entire storage period of the drug, various methods of identification and quantification of the active substances are needed. And despite the fact that spectrophotometry in the UV region is not very specific and selective, the expressness of these methods allows them to be widely used for routine quality control of drugs.

Some aspects of state quality control of medicinal products at regional level

The aim of this article is the analysis of normative legal acts that characterize changes in the legislation on the quality control of medicines, regulations and orders of the State Medical Service of Ukraine regarding the prohibition of the implementation of medical devices in the last 5 years and the substantiation of the conclusions aimed at further improving the quality assurance medical products (m/p). Results. It was revealed that of the 41 supplier countries in Ukraine, the predominant number of m/p that were banned from marketing, was found in 9 countries (67.98 %). The largest number of m/p that fell under the ban falls to Ukraine (32.25 %), India (15.98 %) and Germany (15.68 %), the lowest number of such m/p is represented by Belgium (5.03 %) Under the prohibition on the implementation of m/p by the release forms, the most commonly burned m/p in tablet form (43.63 %). Anti-hypertensive agents (18.23 %), antiseptic and disinfectants (15.63 %), as well as hormonal (15.63 %) were the leaders among the m/p for the pharmacological groups that most often fell under the prohibition on implementation. Conclusions. The analysis of the orders and instructions of the State Service of Ukraine to ban the sale of drugs in 2015-2018 indicates a significant decrease in their number in 2018, which indicates the improvement of the state drug quality control system. The largest number of drugs that were banned were found in Ukraine, India and Germany; predominant drugs in pill and liquid forms; Most often, antihypertensive, antiseptic, disinfecting and hormonal agents were banned. The introduction of a unified system for monitoring drug trafficking by labeling medicines with control identification marks based on 2-D coding will allow you to track the entire supply chain of medicines from the manufacturer to the end user and, accordingly, strengthen control over the quality of medicines, their production and import, which will counteract the ingress to Ukraine counterfeit or counterfeit drugs.

Culture Media in Pharmacopoeial Analysis: Use, Current Requirements, Standardisation

Culture media with predetermined specific characteristics play a key role in ensuring safety, quality and efficacy of medicinal products, especially biologicals. It is necessary to formulate clear criteria for culture media suitability, because they are used not only in manufacture, but also in quality control of medicinal products. The expansion of the range of complex high-technology medicinal products containing biologically derived substances as active ingredients, whose quality and properties are tested by biological methods, calls for more stringent requirements for the quality of culture media. The aim of the study was to analyse requirements for the culture media used in the production of medicinal products — in order to identify approaches to the development of a national standard. Currently, culture media are not included into the State Register of Medicinal Products, and there are no standards that could be used by manufacturers to confirm that a culture medium complies with specific safety, efficacy and quality requirements. The paper summarises the results of the analysis of the State Pharmacopoeia of the Russian Federation, 14th ed., and nine leading world pharmacopeias’ requirements for culture media used for various purposes (manufacture, auxiliary purposes, and quality control). Most countries have adopted requirements mainly for those culture media that are used in purity tests. The analysis revealed differences both in the lists of requirements (test strains, incubation and storage conditions, preparation for use, suitability assessment), and the approaches to the establishment and presentation of requirements. The paper discusses the main challenges and risks associated with the quality control of culture media in accordance with the requirements of the State Pharmacopoeia of the Russian Federation, 14th ed. It outlines current national and international ways of improving the quality of culture media used in the production of medicinal products, and substantiates the need to develop an appropriate national standard. The paper suggests approaches to the development and standardisation of requirements for the quality of various types of media used in the production and control of medicines. These approaches could be used in the preparation of the general chapter Culture media.
