Однако особенности выполнения анализа для данной лекарственной формы в отечественной фармакопее не описаны.</p><sec><title>Цель работы</title><p>Цель работы: разработать методику определения содержания бактериальных эндотоксинов (БЭ) с помощью ЛАЛ-теста в имплантатах на примере гормонального препарата с активным веществом гозерелин.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: выполняли процесс экстракции БЭ с поверхности имплантата в водную среду и определяли содержание БЭ в смыве турбидиметрическим кинетическим методом. Затем имплантат растворяли в диметилсульфоксиде и оценивали наличие БЭ в полученном растворе гозерелина с помощью гель-тромб теста.</p></sec><sec><title>Результаты</title><p>Результаты: на основании существующих в отечественной и зарубежной фармакопейной практике подходов к определению пирогенных примесей в гормональных имплантатах предложено два способа предварительной подготовки образцов для последующего определения содержания БЭ (в смыве и в растворе имплантата). Установлено, что содержание БЭ в водном смыве не превышает 0,01 ЕЭ/мл и составляет менее 0,07 ЕЭ на имплантат. Содержание БЭ в растворе имплантата составило менее 8,3 ЕЭ на 1 мг гозерелина, что почти в 11 раз меньше теоретически рассчитанной нормы.</p></sec><sec><title>Выводы</title><p>Выводы: разработаны две методики определения БЭ в имплантатах гормональных препаратов с помощью ЛАЛ-теста, пригодные для включения в нормативную документацию. Первая методика предусматривает испытание водного смыва с поверхности имплантата с нормой предельного содержания БЭ «не более 20 ЕЭ/изделие». Вторая методика основана на полном растворении имплантата в диметилсульфоксиде с нормой «не более 97,22 ЕЭ на 1 мг гозерелина». </p></sec></abstract><trans-abstract xml:lang="en"><p>The State Pharmacopoeia of the Russian Federation, 14th edition states that implants are a sterile dosage form, and have to be tested for pyrogens. However, it does not provide details on how the test should be performed for this dosage form.</p><p>The aim of the study was to develop a LAL test procedure for detection of bacterial endotoxins (BE) in implants, using the example of a goserelin product.</p><sec><title>Materials and methods</title><p>Materials and methods: BE extraction from the implant surface into an aqueous medium was performed with subsequent BE detection in the extract by turbidimetric kinetic test. The implant was then dissolved in dimethyl sulfoxide, and the obtained goserelin solution was tested for BEs using the gel-clot test.</p></sec><sec><title>Results</title><p>Results: the analysis of the Russian and foreign pharmacopoeial approaches to pyrogenic substance detection in hormonal implants helped to develop two sample preparation procedures for determination of BE content (in the extract and the implant solution). It was demonstrated that the BE content in the water extract did not exceed 0.01 EU/mL and was less than 0.07 EU per implant. The BE content in the implant solution was less than 8.3 EU per 1 mg of goserelin, which is almost eleven-fold lower than the theoretically-derived limit.</p></sec><sec><title>Conclusions</title><p>Conclusions: the authors developed two test procedures for BE detection in hormonal implants using the LAL test, which could be included in manufacturers’ product files. The first procedure involves testing of the water extract from the implant surface and establishes the BE limit of no more than 20 EU/product. The second procedure involves complete dissolution of the implant in dimethyl sulfoxide and establishes the limit of not more than 97.22 EU per 1 mg of goserelin.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ЛАЛ-тест</kwd><kwd>бактериальные эндотоксины</kwd><kwd>пирогены</kwd><kwd>имплантаты</kwd><kwd>гормональные препараты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>LAL test</kwd><kwd>bacterial endotoxins</kwd><kwd>pyrogens</kwd><kwd>implants</kwd><kwd>hormone products</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания ФГБУ «НЦЭСМП» Минздрава России № 056-00005-21-00 на проведение прикладных научных исследований (номер государственного учета НИР 121021800098-4).</funding-statement><funding-statement xml:lang="en">The study reported in this publication was carried out as part of a publicly funded research project No. 056-00005-21-00 and was supported by the Scientific Centre for Expert Evaluation of Medicinal Products (R&amp;D public accounting No. 121021800098-4).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ouédraogo M, Semdé R, Somé TI, Ouédraogo M, Ouédraogo R, Henschel V, et al.
