Therapy with levodopa/benserazide was started at 300 mg/day.  With time symptoms of the disease escalated: gait impairment and motor fluctuations started. Action duration after administration of levodopa/benserazide sin gle dose shortened to 2 hours, peak dose dyskinesia developed, as well as instability with frequent falls. In 2012, clinical picture of the disease included symptoms of DDS. The patient independently increased the drug dose, decreased time between doses, didn’t follow the doctor’s recommendations. Relatives noticed a state of euphoria in the patient after taking a dose of levodopa/benserazide. At the time of visiting the Department of Neurology of the Russian Medical Academy of Continuous Professional Education in the beginning of 2016, the daily equivalent levodopa dose was 2000 mg, and 800 mg of it were taken at night.</p><p><bold>Results.</bold> The patient was transferred to a three-component modern levodopa drug Stalevo (levodopa + carbidopa + entacapone) 150 mg + levodopa/benserazide 50 mg 6 times a day (daily dose 1200 mg). Decreased levodopa daily dose achieved by transferring the patient to a three-component drug with better bioavailability lead to significant reduction of motor and non-motor symptoms, significant increase in effect duration after a single dose of levodopa. In a year of follow-up, DDS symptoms gradually regressed, time between drug administration increased, the patient stopped taking the drug at night, fluctuations and drug-induced dyskinesias significantly decreased.</p><p><bold>Conclusion.</bold> In this clinical case, manifestations of DDS caused by long-term compulsive levodopa intake at doses significantly exceeding daily dose (necessary for control of motor symptoms) are described. One of the approaches to reduction of high doses of levodopa and control of motor fluctuations is prescription of Stalevo which stabilizes levodopa level in plasma and provides a more continuous stimulation of dopamine receptors in the striatum.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель работы</bold> – описание клинического случая дофаминового дизрегуляционного синдрома (ДДС) с компульсивным приемом больших доз препаратов леводопы у пациента с болезнью Паркинсона (БП).</p><p><bold>Материалы и методы</bold>. Больной Р., 1956 г. р., болен БП с 2004 г., когда впервые отметил изменение почерка, трудности в выполнении мелких движений правой рукой. Терапия была начата препаратом леводопа/бенсеразид в дозе 300 мг/сут. Со временем симптомы заболевания стали нарастать, присоединились нарушения походки, моторные флуктуации.  Продолжительность действия после приема однократной дозы леводопы/бенсеразида постепенно сократилась до 2 ч, появились дискинезии пика дозы, а также постуральная неустойчивость с частыми падениями. В 2012 г. в клинической картине заболевания появились симптомы ДДС. Пациент самостоятельно повышал дозу препарата, сокращал интервалы между приемами лекарства, не соблюдал рекомендации врача. На фоне приема очередной дозы леводопы/бенсеразида родственники стали отмечать появление у пациента состояния эйфории. На момент обращения на кафедру неврологии РМАНПО в начале 2016 г. суточная эквивалентная доза леводопы составляла 2000 мг, из них 800 мг принимались в ночное время суток.</p><p><bold>Результаты.</bold> Пациент был переведен на трехкомпонентный современный препарат леводопы – Сталево (леводопа + карбидопа + энтакапон) 150 мг + леводопа/бенсеразид 50 мг 6 раз в день (суточная доза 1200 мг). На фоне снижения суточных доз леводопы за счет перевода больного на трехкомпонентный препарат с большей биодоступностью было отмечено значительное уменьшение моторных и немоторных симптомов, отмечалось значительное удлинение эффекта от приема однократной дозы леводопы. На протяжении 1 года наблюдения был отмечен постепенный регресс симптомов ДДС, удалось увеличить промежутки времени между приемами препарата, пациент перестал принимать лекарство ночью, значительно уменьшилась выраженность флуктуаций, лекарственных дискинезий.</p><p><bold>Заключение.</bold> В данном клиническом случае отображены проявления ДДС на фоне длительного компульсивного приема высоких доз леводопы, значительно превышающих суточную (необходимую для контроля моторных симптомов). Одним из подходов к уменьшению высоких доз леводопы и контроля моторных флуктуаций является назначение препарата Сталево, который стабилизирует уровень леводопы в плазме и обеспечивает более постоянную стимуляцию дофаминовых рецепторов стриатума.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Parkinson’s disease</kwd><kwd>dopamine dysregulation syndrome</kwd><kwd>dopaminergic drugs</kwd><kwd>three-component levodopa drug Stalevo</kwd><kwd>impulsive-compulsive disorders</kwd><kwd>punding</kwd><kwd>dopamine receptor agonists</kwd><kwd>DOPA-decarboxylase inhibitor</kwd><kwd>catechol-O-methyltransferase inhibitor encaptone</kwd><kwd>Unified Parkinson’s Disease Rating Scale</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>болезнь Паркинсона</kwd><kwd>дофаминовый дизрегуляционный синдром</kwd><kwd>дофаминергические препараты</kwd><kwd>трехкомпонентный препарат леводопы Сталево</kwd><kwd>импульсивно-компульсивные расстройства</kwd><kwd>пандинг</kwd><kwd>агонисты дофаминовых рецепторов</kwd><kwd>ингибитор ДОФА-декарбоксилазы</kwd><kwd>ингибитор катехол-О-метилтрансферазы энтакапон</kwd><kwd>унифицированная шкала оценки болезни Паркинсона</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
