This includes a discussion of how the type I error is controlled, i.e. the way how the patient risks arising from the inherent uncertainty of statistical inferences are handled. Additionally, certain weaknesses of the current approach for the bioequivalence assessment are discussed.bioequivalencetype I errorstatistical testбиоэквивалентностьошибка I родастатистический критерий[CFR320.23 https://www.accessdata.fda.gov/scripts/cdrh/ cfdocs/cfcfr/CFRSearch.cfm?fr=320.23.][Информационный справочник понятий, применяемых в рамках Евразийского экономического союза в сфере обращения лекарственных средств http://eec.eaeunion.org/ru/act/texnreg/ deptexreg/LS1/Pages/pharm_glossary.aspx, доступ 01.11.2018.][EMA Guideline on the investigation of bioequivalence, 2010.][Shein-Chung Chow, Jen-pei Liu, Design and Analysis of Bioavailability and Bioequivalence Studies, Third Edition, by Taylor & Francis Group, LLC, 2009.][Schuirmann D.J.
