В настоящей работе были синтезированы полимерные комплексы цефалоспориновых антибиотиков третьего поколения цефтриаксона и цефотаксима с водорастворимым производным целлюлозы – сульфатом ацетатом в форме натриевой соли. Полученные комплексы охарактеризованы методами УФ- и ИК-спектроскопии. Путем иммобилизации комплекса на активированном угле получены кислотоустойчивые таблетированные лекарственные формы для перорального применения, которые могут быть предложены для проведения доклинических и клинических испытаний. </p></abstract><trans-abstract xml:lang="en"><p>The state-of the-art in antibiotics modification is the development of acid resistant dosage forms for per oral treatment. This article is about the synthesis of complexes of ceftriaxone and cefotaxime, 3rd generation antibiotics of cephalosporines family, with new water-soluble cellulose derivative – acetate sulfate sodium salt. The composition of complexes was established by UV- and FTIR-spectroscopy. Stable in acid media tablet dosage form of antibiotics was prepared by the immobilization of complexes on activated carbon. Release of the major quantity of antibiotics was proved by HPLC method to be in alkaline media modeling the intestine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>антибиотик</kwd><kwd>цефалоспорин</kwd><kwd>сульфатированный полисахарид</kwd><kwd>полимерный комплекс</kwd><kwd>таблетка</kwd><kwd>инъекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>antibiotic</kwd><kwd>cephalosporin</kwd><kwd>sulfated polysaccharide</kwd><kwd>polymer complex</kwd><kwd>tablet</kwd><kwd>injection</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">Pharmacokinetics of a new, orally available ceftriaxone formulation in physical complexation with a cationic analogue of bile acid in rats / L.
