Title (EN) METHOD OF OBTAINING HYDROGELS OF CYCLODEXTRINS WITH GLYCIDYL ETHERS, COMPOSITIONS THUS OBTAINED AND APPLICATIONS THEREOF
(ES) PROCEDIMIENTO DE OBTENCIÓN DE HIDROGELES DE CICLODEXTRINAS CON GLICIDILÉTERES, LAS COMPOSICIONES OBTENIDAS Y SUS APLICACIONES
(FR) PROCEDE D'OBTENTION D'HYDROGELS DE CYCLODEXTRINES AVEC DES GLYCIDYLETHERS, COMPOSITIONS OBTENUES ET APPLICATIONS
Abstract: front page image
(EN)The invention relates to a method of obtaining hydrogels based on (i) cyclodextrins, (ii) cyclodextrins and cellulose ethers or (iii) cyclodextrins and guar gum or the derivatives of same, using molecules containing two or more glycidyl ether groups in the structure thereof as a cross-linking agent. The invention also relates to the compositions thus obtained, which can include active substances and pharmaceuticals and which form inclusion complexes with cyclodextrins. The invention further relates to the use of same as components of controlled-release devices, such as transdermal pharmaceutical forms, vaginal, otic, ocular, rectal, oral or buccal transmucosal forms and parenteral implants, which are designed to administer active substances or pharmaceuticals to humans, animals or plants, or as components of cosmetic formulations. In addition, the invention relates to the use of said compositions as chelating agents in the extraction of biological or toxic molecules from living organisms or contaminating substances from water.
(ES)Procedimiento de obtención de hidrogeles a base de ciclodextrinas, de ciclodextrinas y éteres de celulosa, o de ciclodextrinas y goma guar o sus derivados, utilizando como agente reticulante moléculas que contienen dos o más grupos glicidiléter en su estructura; las composiciones obtenidas capaces de incorporar fármacos y sustancias activas, que forman complejos de inclusión con ciclodextrinas; su uso como componentes de dispositivos de liberación controlada, tales como formas farmacéuticas transdérmicas, formas transmucosales bucales, orales, rectales, oculares, óticas o vaginales, e implantes parenterales, destinadas a administrar fármacos o sustancias activas a humanos, animales o plantas, o como componentes de preparados cosméticos; y el uso de las composiciones como secuestrantes, en la extracción de moléculas tóxicas o biológicas en organismos vivos o de sustancias contaminantes en aguas.
(FR)L'invention concerne un procédé d'obtention d'hydrogels à base de cyclodextrines, de cyclodextrines et d'éthers de cellulose, ou de cyclodextrines et de gomme de guar, ou de leurs dérivés, consistant à utiliser comme agent de réticulation des molécules contenant deux ou plusieurs groupes glycidyléther dans leur structure. L'invention concerne également les compositions obtenues, celles-ci pouvant incorporer des produits pharmaceutiques et des substances actives formant des complexes d'inclusion avec des cyclodextrines, leur utilisation en tant que composants de systèmes à libération contrôlée, par exemple des formes pharmaceutiques transdermiques, des formes transmucosales, buccales, rectales, oculaires, otiques ou vaginales, et des implants parentéraux, permettant d'administrer des médicaments ou des substances actives à des humains, des animaux ou des plantes, ou en tant que composants de préparations cosmétiques. L'invention concerne enfin l'utilisation des compositions comme agents séquestrants dans l'extraction de molécules toxiques ou biologiques d'organismes vivants, ou de substances contaminantes des eaux.
