Russian. Целью исследования было изучение антигельминтной эффективности супрамолекулярного комплекса фенбендазола (СКФ) против разных видов нематод у овец. Опыты проводили на молодняке овец, спонтанно инвазированном желудочно-кишечными стронгилятами (48 гол.), Dictyocaulus filaria (42 гол.), Strongyloides papillosus (21 гол.) и Trichocephalus ovis (24 гол.). При каждом гельминтозе овцам разных групп задавали однократно перорально СКФ в дозе 3,0; 2,0 и 1,0 мг/кг по действующему веществу (ДВ) в сравнении с базовым препаратом фенбендазолом в дозах 1,0 и 3,0 мг/кг. Контролем служила группа овец, не получавшая препарат. Эффективность препаратов учитывали по результатам копрооволарвоскопических исследований методом флотации и Бермана до и через 18 сут после дегельминтизации. Учет активности препаратов проводили по типу "контрольный тест". Изучена антигельминтная эффективность и установлена терапевтическая доза СКФ, полученного по механохимической технологии с адресной доставкой Drug Delivery System. Комплекс в дозах 3,0; 2,0 и 1,0 мг/кг по ДВ показал, соответственно, 100; 93,4 и 78%-ную эффективность при стронгилятозах пищеварительного тракта, 100; 92,4 и 76,0%-ную – против D. filaria. Эффективность комплекса в дозе 3,0 мг/кг составила против S. papillosus 100 % и против T. ovis 98,3 % при 10–13%-ной эффективности базового препарата фенбендазола в дозе 1,0 мг/кг. Терапевтическая доза СКФ при основных нематодозах овец составила 3,0 мг/кг по ДВ.

Experiments were carried out on young sheep spontaneously infected with gastrointestinal strongylates (48 head), Dictyocaulus filaria (42 head), Strongyloides papillosus (21 head) and Trichocephalus ovis (24 head). In each helminthiasis, the SCF was given once orally to sheep from various groups at the dose of 3.0; 2.0 and 1,0 mg of active ingredient (a.i.)/kg in comparison with the base preparation Fenbendazole at the doses of 1.0 and 3.0 mg/kg. Sheep which didn't receive the drug served as controls. The efficacy of drugs was evaluated before and 18 days after dehelmintization according to the results of coprolarvoscopic examination by flotation and G. Baermann methods. The registration of drug activity was performed using the "control test". The anthelminthic efficacy was studied and a therapeutic dose for the SCF produced by the chemical mechanical technology using the Drug Delivery System was determined. In gastrointestinal strongylatoses the supramolecular complex against D. filaria at the doses of 3.0; 2.0 and 10 mg a.i./kg showed the efficacy of 100; 9.4 and 78%, respectively. The efficacy of supramolecular complex at the dose of 3.0 mg/kg against S. papillosus was 100 %, and against T. ovis - 98.3 % at 10–13% efficacy of the base preparation Fenbendazole at the dose of 1.0 mg/kg. The therapeutic dose for the SCF at main nematodiasis in sheep was 3.0 mg a.i./kg.
