The results of the multicenter open-label observational study of Circadin (prolonged-release melatonin) efficiency for treatment of insomnia in 36 patients older than 55 yeare presented. The drug was administered at a dose of 2 mg one-two hours before bedtime for 3 weeks.</p></sec><sec><title>Results</title><p>Results. Treatment with Circadin resulted in statistically significant (p&lt;0.0001) according to pared t-test (95% CI: 4.8; 7.3) improvement of the sleep quality: the mean value of the modified subjective sleep characteristics scale increased from 11.8±2.6 points at baseline to 17.8±2.3 points after 3 weeks of treatment. The modified Questionnaire Scoring Subjective Characteristics of Sleep was grade from 0 (very bad) to 20 (very good) taking into account: the amount of time required to fall asleep, the sleep duration, the number of night awakenings and the general well-being in the morning. An increase of 6 points on a scale from 0 to 20 was considered as clinically relevant. A greater effect was observed in patients with severely impaired sleep quality as well as with low level of depression and anxiety and absence of cognitive impairment. Upon completion of Circadin treatment there were statistically significant improvement (p&lt;0.0001) of attention (the mean value of the symbol-digit coding test increased from 34.2±9.7 to 37.3±10.6 points) and memory (the median value of the short-term verbal memory test increased from 4 points at baseline to 5 points at the study end, p=0.0069).</p><p>The drug had a good safety profile; only one adverse event related to study medication (allergic rush) was registered in the study. The absolute majority (91.7%) of the study patients considered Circadin treatment as either effective or very effective.</p></sec><sec><title>Conclusion</title><p>Conclusion. Taking into consideration the good safety profile of this drug, confirmed in the present study, as well as the ability of the drug to improve cognitive functions, Circadin may be beneficial in patients from 55 years with insomnia complaint.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Цель исследования – оценка эффективности препарата мелатонина пролонгированного высвобождения (циркадин), применяемого в рутинной клинической практике для улучшения качества сна у российских пациентов старше 55 лет.</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. Представлены результаты многоцентрового открытого наблюдательного исследования эффективности мелатонина пролонгированного высвобождения при лечении инсомнии у больных старше 55 лет.</p><p>Препарат назначали в дозе 2 мг за 1–2 ч до сна в течение 3 нед.</p></sec><sec><title>Результаты</title><p>Результаты. На фоне терапии циркадином отмечено достоверное (p&lt;0,0001) улучшение качества сна: среднее значение модифицированной балльной шкалы субъективных характеристик сна увеличилось с 11,8±2,6 балла во время исходного визита до 17,8±2,3 балла через 3 нед лечения. Более заметный эффект препарата отмечен у пациентов с плохим качеством сна, а также с низким уровнем депрессии и тревоги и отсутствием когнитивных нарушений.</p><p>После завершения лечения мелатонином пролонгированного высвобождения статистически достоверно (p&lt;0,0001) улучшились внимание (среднее значение теста символьно-цифрового кодирования увеличились с 34,2±9,7 до 37,3±10,6 балла) и память (медиана результатов теста краткосрочной вербальной памяти увеличилась с 4 баллов исходно до 5 баллов в конце исследования, p=0,0069).</p><p>Препарат характеризовался хорошим профилем безопасности; в ходе исследования отмечено лишь одно нежелательное явление (аллергическая сыпь), связанное с приемом препарата. Абсолютное большинство (91,7%) участвовавших в исследовании больных оценили терапию как «эффективную» и «очень эффективную».</p></sec><sec><title>Заключение</title><p>Заключение. Учитывая уникальный профиль безопасности циркадина, подтвержденный и в ходе настоящего исследования, а также способность улучшать когнитивные функции, препарат может рассматриваться в качестве терапии первого ряда у пожилых больных.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>инсомния</kwd><kwd>сон</kwd><kwd>внимание</kwd><kwd>память</kwd><kwd>пожилые пациенты</kwd><kwd>циркадин</kwd><kwd>эффективность</kwd><kwd>безопасность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>insomnia</kwd><kwd>sleep</kwd><kwd>attention</kwd><kwd>memory</kwd><kwd>elderly patients</kwd><kwd>Circadin</kwd><kwd>efficacy</kwd><kwd>safety</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">Schutte-Rodin S, Broch L, Buysse D, et al.
