Несмотря на хорошо известные особенности фармакокинетики и фармакодинамики левотироксина натрия, не всем пациентам, принимающим его в таблетированной форме, удается достичь индивидуальных целей лечения. Среди основных причин неэффективности терапии — неудобный режим приема препарата с необходимостью выдерживать временные интервалы перед едой и приемом других лекарственных средств, а также целый ряд желудочно-кишечных заболеваний, влияющих на биодоступность левотироксина натрия. Данное обстоятельство способствовало появлению исследований, направленных на поиск новых лекарственных форм левотироксина, обладающих большими преимуществами с точки зрения достижения клинического эффекта в сравнении с таблетированной формой. В настоящем обзоре приведены последние данные об использовании новых лекарственных форм левотироксина. Необходимо дальнейшее проведение крупных клинических испытаний для более обоснованного и широкого использования новых лекарственных форм левотироксина в клинической практике.</p></abstract><trans-abstract xml:lang="en"><p>Levothyroxine steadily maintains its position as the «gold standard» in the treatment of hypothyroidism. Despite the possibility of step-by-step tableted dose titration of levothyroxine, the results of many studies reliably point to the fact that a significant number of patients do not reach the target level of thyroid hormone. One of the main reasons for the therapy ineffectiveness is the inconvenience of levothyroxine sodium regimen for many patients, associated with the need to observe certain time intervals before meals and other medications. The above-mentioned factors have stimulated a number of studies aimed at developing new dosage forms with significant advantages in the pharmacokinetics and pharmacodynamics of drugs. The review provides the latest data on the new dosage forms of levothyroxine. Further large-scale clinical trials are needed for a more reasonable and widespread use of new dosage forms of levothyroxine in clinical practice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>левотироксин натрия</kwd><kwd>первичный гипотиреоз</kwd><kwd>вторичный гипотиреоз</kwd><kwd>хронический аутоиммунный тиреоидит</kwd><kwd>лекарственные формы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>levothyroxine</kwd><kwd>primary hypothyroidism</kwd><kwd>secondary hypothyroidism</kwd><kwd>chronic autoimmune thyroiditis</kwd><kwd>dosage forms</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания № 123021300097-0 «Гормонально-метаболические и молекулярно-клеточные характеристики заболеваний щитовидной железы как основа для разработки инновационных методов диагностики, лечения и профилактики».</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">Jonklaas J, Bianco AC, Bauer AJ, et al.
