Revision of the National Part to the General Text 5.12. «Reference Standards» to be included in Supplement 1 to the 2d Edition of the State Pharmacopoeia of Ukraine

The expediency of revising the national part to the General Text 5.12 «Reference Standards» of the State Pharmacopoeia of Ukraine (SPU) was shown. A comparative analysis of the texts of the European Pharmacopoeia and SPU in terms of terminology for the pharmacopeial reference standards (PhRS) was conducted. The explanation about the conformity of the terms used by the European Pharmacopoeia and SPU regarding reference standards was given. The status of SPU PhRS was clarified. Reference standards of the European Pharmacopoeia are official for quality control of medicines described in the European Pharmacopoeia; in all other cases, SPU PhRS are official. If a national SPU monograph exercises texts retrieved from the monographs of the United States Pharmacopoeia (USP) or British Pharmacopoeia (BP), reference standards of corresponding pharmacopoeias (USP RS or BP CRS) may be used as official along with SPU PhRS; in this case, a link to the corresponding reference standard is given in the monograph. SPU PhRS are characterised using the principle of insignificance of the uncertainty for the assigned values of reference standards. With high reliability, the same conclusion about quality of an analysed medicinal product can be made whether SPU PhRS or those of other pharmacopoeias are used. The statement significant for users that in routine analysis, SPU PhRS can be used instead of reference standards of the European Pharmacopoeia has been introduced. However, in case of doubt about the test results or dispute between the parties, official reference standards should be used. It was explained that users are provided with all necessary information for correct use of SPU PhRS in non pharmacopeial procedures. Information about the uncertainty of assigned value of SPU PhRS and clearly defined metrological approaches to certification and use of reference standards allows users to control the risk of making an incorrect decision about quality of medicinal products. In addition, it enables them to certify working reference standards for quantitative tests metrologically correctly. Terms of use of working reference standards were clarified. Theses uninformative for users were excluded. On the basis of this work, a new version of the national part to the General Text 5.12 «Reference Standards» to be included in Supplement 1 to the 2d Edition of the State Pharmacopoeia of Ukraine was developed.

Keywords: pharmacopoeial reference standards, terminology, metrological aspects of use, accompanying documentation, working reference standards, General Text 5.12, national part, the State Pharmacopoeia of Ukraine.

The main trends in the harmonization of the requirements of production and quality control of cosmetic products in Ukraine with EU requirements in the light of membership of Ukraine in European Pharmacopoeia

For discussion for all pharmaceutical community on the basis of the stated approach to cosmetic means in the EU and France, as well as the state regulatory framework in Ukraine submitted key questions. In 1997, the Ukraine Pharmacopoeial Center received the status of Observer to the European Pharmacopoeia, the first of all former USSR countries. In 2001 issued by the State Pharmacopoeia of Ukraine, harmonized with EP. In 2013, the Ukraine Pharmacopoeial Center became a full member of the European Pharmacopoeia. This implies the recognition on the territory of Ukraine of the requirements of the EP to the quality of drugs. Organizational European Pharmacopoeia is created by participating countries on the basis of the European Directorate for the Quality of Medicines (EDQM). This implies that the goals and objectives of the Ukraine Pharmacopoeial Center, the structure must match what is in EP, i.e. EDQM. Considered the question of the regulation of cosmetic products in the EU and France, as one of the three «pillars» of the EU. In the European Pharmacopoeia does not contain monographs on cosmetics (such as in the French Pharmacopoeia, the Pharmacopoeia of the United States, China Pharmacopoeia, the UK Pharmacopoeia), but, nevertheless, work on the harmonization of the requirements in the various EU countries require the creation of a working group (it exists in EP) for clinical trials and progressive therapy.

Keywords: cosmetics, pharmaceuticals, The State Pharmacopoeia of Ukraine, European Pharmacopoeia, the regulatory framework of cosmetic products.

Relevance of quality control of drugs in terms of «Depressor substances». Generalizing analysis of tests

What is the relevance of the quality control of drugs that contain ‘depressor substances’? The following is a summary of the test analysis; It is a requirement of the regulatory documents that any adverse effects of antibacterial drugs and biological medical product that is isolated from animal sources be tested against the normal permissible standards. This has been done by carrying out intravenous injections of cats with drugs from microbial (kanamycin, lincomycin, streptomycin, gentamicin), semi-synthetic (doxorubicin) and animal (heparin) sources. We carried out a comprehensive analysis of experimental data on any unwanted depressant effects of antibacterial pharmaceuticals and it was determined that the vasoactive substance antihyperitensive response does not exceed the appropriate accepted standard. The data suggests a number of undesirable impurities of histamine-like substances in the tested drugs and this would justify that these be biologically controlled in an appropriate test.

Keywords: depressor substance, histamine, vasodilatations, cats, biological methods of control.

Prediction of death due 6 months in patients with acute Q-positive myocardial infarction

It is shown that there is an increased interest in the world in optimizing the scales of risk stratification of patients with acute myocardial infarction (AMI) due to the high mortality in this disease. The aim of this study was to define the utility of the measurement N-terminal pro-brain natriuretic peptide (NT-proBNP) and other clinical and biochemical markers to predict death at 6 months in patients with AMI. We included 151 consecutive patients admitted in hospital for acute Q-positive myocardial infarction. The parameters in patients with and without adverse events were taken for analysis: age, levels of creatinine and NT-proBNP, localization of infarction. Curves of sensitivity and specificity were used based on the method of ROC-analysis and cut-off values were chosen for each variable. Ball scoring was performed for each parameter regard to the cut-off value and a scale for calculating the summarized diagnostic coefficient by the method of Gubler was offered. We had performed a model of risk stratification of patients with acute myocardial infarction within 6 months, taking into account the patient’s age, the levels of creatinine and NT-proBNP, and localization of myocardial infarction. The sensitivity of the proposed model in predicting lethal result in patients with acute myocardial infarction was 81 %, specificity — 85 %, the area under the curve — 0.893.

Keywords: myocardial infarction, prediction of death, NTproBNP.
