Лекарственные препараты ботулинического токсина представляют собой хороший пример использования смертельно опасного токсина в составе уникальных терапевтических препаратов. Однако остается много нерешенных вопросов в отношении биотехнологии, биологической активности, взаимозаменяемости и стандартизации препаратов ботулотоксина.</p></sec><sec><title>Цель</title><p>Цель. Обзор актуальных направлений по совершенствованию лекарственных препаратов на основе ботулинического токсина.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. Рассмотрены лекарственные препараты ботулинического токсина типа А, а также связанные с ними вопросы, требующие решения. Зарегистрированные отечественные и зарубежные лекарственные препараты ботулинического токсина типа А из-за отсутствия международных непатентованных наименований, рекомендованных Всемирной организацией здравоохранения, Коллегией Евразийской экономической комиссии, а также в Российской Федерации, имеют только группировочные наименования. Кроме того, каждый производитель присваивает собственные наименования препаратам ботулотоксина. Для более четкой идентификации, правильного выбора и назначения требуются унификация названий и объединение данных препаратов в одну группу. Продемонстрирована особенность препаратов ботулинического токсина типа А — их существенное различие по многим параметрам, которое не позволяет считать эти препараты сопоставимыми по качественным и количественным характеристикам, что порождает проблему взаимозаменяемости и биоэквивалентности. В связи с этим требуется разработка и закрепление в соответствующих нормативных документах единой номенклатуры лекарственных препаратов ботулотоксина. Анализ данных литературы показал, что производители используют собственные стандартные образцы, поэтому при определении токсичности и лечебного действия разных препаратов ботулотоксина одной и той же единице измерения активности может соответствовать различная белковая нагрузка. В связи с этим рассмотрены вопросы разработки единого международного стандартного образца для определения активности ботулинического токсина типа А с целью стандартизации имеющихся и вновь создаваемых препаратов.</p></sec><sec><title>Заключение</title><p>Заключение. Описаны препараты ботулотоксина, имеющие новый состав, в том числе находящиеся на поздних стадиях разработки. Обобщенные данные клинических исследований по эффективности, безопасности и рентабельности препаратов ботулинического токсина типа А могут служить ориентиром для терапевтических назначений.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Scientific relevance</title><p>Scientific relevance. Botulinum toxin preparations are a good example of using a deadly toxin as a unique therapeutic agent. However, there are many unresolved issues related to biotechnology, biological activity, interchangeability, and standardisation of botulinum toxin preparations.</p></sec><sec><title>Aim</title><p> Aim. To review current opportunities for improving therapeutic botulinum toxin preparations.</p></sec><sec><title>Discussion</title><p>Discussion. This review covers botulinum toxin type A preparations and unresolved issues related to them. In the absence of international non-proprietary names recommended by the World Health Organisation or by the Board of the Eurasian Economic Commission, domestic and imported botulinum toxin type A preparations approved in Russia have only similarity-based grouping names. In addition, manufacturers name botulinum toxin preparations at their discretion. Therefore, classifying these preparations under a common nomenclature is essential for clear identification, adequate selection, and correct prescription. Several studies have shown significant variability across botulinum toxin type A preparations. Due to the identified differences in qualitative and quantitative characteristics, botulinum toxin type A preparations cannot be considered similar, which raises the issue of their interchangeability and bioequivalence. To resolve this issue, a unified classification and naming system for botulinum toxin preparations should be established and documented in regulatory standards. According to the literature, manufacturers of botulinum toxin preparations use in-house reference standards. Hence, the same activity unit resulting from toxicity and efficacy studies may express a different protein load for each botulinum toxin preparation. Keeping that in mind, the authors discuss the development of a single international potency standard for existing and pipeline botulinum toxin type A preparations.</p></sec><sec><title>Conclusions</title><p> Conclusions. The article describes novel pharmaceutical compositions containing botulinum toxin, including those in late development. Summarised data from clinical studies on the safety, efficacy, and cost-effectiveness of botulinum toxin type A preparations can guide prescribing decisions.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ботулинический токсин</kwd><kwd>биологическая активность препаратов ботулотоксина</kwd><kwd>биоэквивалентность лекарственных средств</kwd><kwd>биосимиляры</kwd><kwd>международные стандарты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>botulinum toxin</kwd><kwd>biological activity of botulinum toxin preparations</kwd><kwd>bioequivalence</kwd><kwd>biosimilars</kwd><kwd>international standards</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания ФГБУ «НЦЭСМП» Минздрава России № 056-00052-23-00 на проведение прикладных научных исследований (номер государственного учета НИР 121022000147-4).</funding-statement><funding-statement xml:lang="en">The study reported in this publication was carried out as part of publicly funded research project No. 056-00052-23-00 and was supported by the Scientific Centre for Expert Evaluation of Medicinal Products (R&amp;D public accounting No. 121022000147-4).</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">Camargo CHF, Teive HAG.
