Согласно данным литературы и опыту экспертной оценки результатов доклинических исследований, неправильный выбор высокой дозы является весьма распространенной ошибкой планирования токсикологических исследований, которая значительно сокращает или полностью лишает их информативности и не позволяет использовать для оценки безопасности применения нового лекарственного средства у человека.</p><p>Цель работы: анализ актуальных регуляторных требований по выбору высокой дозы для исследований общетоксического действия лекарственных средств.</p><p>Проведенный анализ позволил предположить, что возможной причиной необоснованного выбора высокой дозы в токсикологических исследованиях является неоднозначность интерпретации методических рекомендаций в случае отсутствия в них конкретного указания на нормирование предела верхней границы исследуемых токсических доз или достаточной определенности критериев выбора дозы. Соблюдение требований регуляторной токсикологии в отношении выбора доз и применение обоснованного алгоритма принятия решений являются необходимыми условиями корректного планирования доклинических исследований безопасности новых лекарственных средств.</p></abstract><trans-abstract xml:lang="en"><p>High dose selection is a key methodological element in general toxicity studies of medicines. It determines the informative value of study results, the compliance with the principles of ethical and rational use of experimental animals, and the accuracy of predicting the safety of new medicines for human use. The literature data and the regulatory experience in evaluating preclinical study results suggest that the selection of an inappropriate high dose is a very common error in planning toxicity studies. This error leads to a significant or complete loss of the informative value of study results; the results become useless for assessing the safety of new medicinal products for human use.</p><p>The aim of this study was to analyse the current regulatory requirements for high dose selection for general toxicity studies of medicines.</p><p>The analysis suggests that unreasonably high doses may be selected for toxicity studies because methodological recommendations are prone to interpretation errors. Their potential for ambiguity stems from the absence of specific standardised upper limits for toxic doses or sufficiently clear dose selection criteria. Prerequisites for properly planning preclinical safety studies of new medicines include compliance with dose selection requirements of regulatory toxicology and implementation of a clinically and toxicologically sound decision-making algorithm.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>доклинические исследования</kwd><kwd>выбор высокой дозы</kwd><kwd>безопасность лекарственных средств</kwd><kwd>общетоксическое действие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>preclinical studies</kwd><kwd>high dose selection</kwd><kwd>drug safety</kwd><kwd>general toxicity</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 121021800098-4).</funding-statement><funding-statement xml:lang="en">The study reported in this publication was carried out as part of publicly funded research project № 056-00052-23-00 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">Sewell F, Corvaro M, Andrus A, Burke J, Daston G, Delaney B, et al.
