В статье изучаются особенности применения урсодезоксихолевой кислоты (УДХК) в аспекте безопасности и рисков нежелательных реакций. Анализируются инструкции по медицинскому применению, результаты токсикологических исследований на животных, клинических исследований на пациентах с разной патологией, приводятся метаанализы результатов исследований. В статье приводятся актуальные данные об использовании УДХК при беременности и в детском возрасте. Учитывая особенности зарегистрированных в инструкции показаний в детском возрасте, обсуждается возможность использования УДХК в педиатрии. Инструкция по медицинскому применению является официальным документом, утвержденным Минздравом России, в основание ее положены данные исследований, что подтверждает безопасность применения в педиатрической практике. Изучаются терапевтические возможности УДХК, эффективность и безопасность. В результате анализа многочисленных исследований не обнаружено свидетельств токсичности или низкого профиля безопасности УДХК. Напротив, большое количество исследований посвящено категориям пациентов, являющихся эталоном безопасности, подтверждают отсутствие токсичности и высокую эффективность УДХК. Сообщения о токсичности УДХК следует считать некорректными и необоснованными.
The article studies the characteristics of ursodeoxycholic acid (UDCA) application in terms of safety and the risk of adverse effects. We have analyzed the instructions of medical application, the results of toxicological studies using animals, clinical trials of patients with different pathologies and meta-analysis of the results of the studies. This article deals with the actual results on the use of UDCA in pregnancy and childhood. We discuss the possibility of the usage the UDCA in pediatric patients, according to the characteristics of application of registered instruction in childhood. The instruction of medical application is an official document approved by the Ministry of Health, at the baseline of it are placed the results of the studies that confirm the safety of the usage of UDCA in pediatric practice. We have studied the therapeutic possibilities of UDCA usage and the safety and efficacy. As follows from the analysis of numerous studies we have found no evidence of toxicity or low-profile safety of the usage of UDCA. In contrast, the large number of studies are devoted to the categories of patients the so-called safety standard, confirm the absence of toxicity and high efficiency of UDCA. The reports of toxicity of UDCA should be considered incorrect and unfounded.
Key words: ursodeoxycholic acid, safety, toxicity, side effects, adverse effects.
