Earlier studies have shown that combination of antibodies to S100 protein and to cannabinoid receptor type 1 in released-active form (Brizantin) may possess anxiolytic properties and decrease nicotine dependence. Released-active form of antibodies is a novel approach that permits to modify natural functions of the target molecule (antigen) under investigation. The aim of the present study was to evaluate the anxiolytic-like effect of Brizantin in the light–dark test in mice, according to its ability to influence the number of entries into the lit compartment and the total time spent there. Three doses of Brizantin (2.5, 5, and 10 mL/kg) were compared with diazepam (1 mg/kg), placebo, and vehicle control. Anxiolytic-like effect of the tested drug was shown to be dose dependent, with an increasing trend from 2.5 to 10 mL/kg. Brizantin in its highest dose significantly increased studied behavioral parameters, although its effect was less pronounced than that of the reference drug diazepam (1 mg/kg).
В медицинской практике достаточно часто возникает необходимость в одновременном приеме нескольких лекарственных средств. Иногда это оказывается невозможным в силу наличия у препаратов гепатотоксических свойств, поэтому актуальными задачами фармакологии являются как поиск и разработка новых препаратов, так и оптимизация уже существующих с целью уменьшения побочных эффектов при их приеме. В настоящем обзоре были проанализированы данные о фармакологических препаратах класса гепатопротекторов, разобраны механизмы их действия и потенциал поиска новых препаратов. В заключение отмечено, что в настоящее время в клинической практике наибольшей популярностью пользуются препараты, содержащие эссенциальные фосфолипиды и препараты, улучшающие рециркуляцию и выведение желчных кислот. Существуют теоретические обоснования механизмов действия этих препаратов и перспектива накопления доказательной базы для них в виде рандомизированных клинических исследований и мета-анализов.
Medical practice quite often requires simultaneous administration of several drugs. Sometimes it is impossible due to their hepatotoxicity; therefore, urgent tasks of pharmacology include searching for and developing new drugs as well as optimizing already existing products in order to reduce side effects during their administration. This review focused on pharmacological drugs of the hepatoprotector class and their mechanisms of action and evaluated the prospects of searching for new medicines. In conclusion, drugs containing essential phospholipids and those improving recirculation and removal of bile acids are currently the most popular agents in clinical practice. Mechanisms of action of these drugs are theoretically justified and there is a prospect for building an evidence base for them by randomized clinical trials and meta-analyses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
