Оценка контаминации контрольных образцов является необходимым элементом подтверждения корректности исследований токсикокинетики (ТК), сопутствующим изучению токсичности лекарственных веществ и препаратов. Вместе с тем недостаточная проработка действующих регуляторных документов обуславливает необходимость обсуждения практических аспектов и совершенствования регуляторной базы. Цель. Работа посвящена рассмотрению экспериментального опыта по оценке контаминации контрольных проб в исследованиях ТК. Материалы и методы. В качестве экспериментальных примеров рассмотрены два исследования ТК лекарственных препаратов, выполненные с использованием самцов и самок кроликов при пероральном введении исследуемых препаратов в течение 28 (исследование 1) или 90 (исследование 2) дней. Результаты. В исследовании 1 выявлен уровень контаминации 17–25 % (в первый и последний дни введения исследуемого препарата соответственно). Контаминация биопроб происходит in vivo (контаминация организма животного) и ex vivo (на этапе забора биопроб, на преаналитическом и аналитическом этапах). Характер обнаружения аналита в пробах позволил исключить контаминацию in vivo, результаты внутреннего расследования позволили предположить, что она происходила на этапе отбора биопроб. В исследовании 2 реализован ряд профилактических мер и получен незначительный уровень контаминации (0,83 %), не оказавший влияния на полноту и корректность интерпретации результатов. Заключение. На основании экспериментального опыта сформулированы рекомендации по минимизации и профилактике контаминации контрольных образцов при выполнении биологической части, преаналитического и аналитического этапов исследований. Предположительно, при наличии случайного характера загрязнений, свидетельствующего о его ex vivo происхождении, уровень контаминации, не превышающий 25 %, можно считать незначительным, то есть не ведущим к дальнейшему отклонению и аннуляции результатов всего исследования.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. The evaluation of control samples contamination is a necessary element for confirming the correctness of toxicokinetic studies (TK), concomitant with the study of toxicity of drugs and products. At the same time, insufficient elaboration of existing regulatory documents necessitates discussion of practical aspects and improvement of the regulatory framework. Purpose. The work is devoted to the consideration of experimental experience of control samples contamination in TK studies. Materials and methods. As experimental examples, two studies of TK drugs performed using rabbits with oral administration of study drugs for 28 (Study 1) or 90 (Study 2) days were considered. Results. Study 1 revealed a contamination level of 17–25 % (on the first and last days of study drug administration, respectively). Contamination of bioassays can occur in vivo (contamination of animals) and ex vivo (at the stage of bioassay sampling, at the pre-analytical stage and analytical stage). The nature of the analyte detection in the samples made it possible to exclude contamination in vivo, and the results of an internal investigation suggested that it occurred at the stage of biosample selection. In Study 2, a number of preventive measures were implemented and a slight level of contamination was obtained (0.83 %), which did not affect the completeness and correctness of results interpretation. Conclusion. Based on experimental experience, recommendations for minimizing and preventing contamination of control samples during the biological part, pre-analytical and analytical stages of studies were formulated. Presumably, in the presence of a random nature of contamination indicating its ex vivo origin, the level of contamination not exceeding 25 % can be considered insignificant, i.e. not leading to further deviation and cancellation of the results of the entire study</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аннулирование результатов исследования</kwd><kwd>контаминация</kwd><kwd>регуляторные документы</kwd><kwd>токсикокинетика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cancellation of study results</kwd><kwd>contamination</kwd><kwd>regulatory documents</kwd><kwd>toxicokinetics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Welling PG.
