The invention concerns microparticulate systems with modified release of oral active principle(s). The invention aims at providing a novel pharmaceutical with time-dependent and pH-dependent release mechanism, enabling: a) the latent period preceding the release of the active principle in the stomach; b) the pH triggering the release of the active principle in the intestine; c) the release speed of the active principle. This is achieved through the use of coated microparticles made from particles of active principle each coated with two coating films A and B. A comprises: film-forming (co)polymer (A1) insoluble in fluids of the gastrointestinal tract; ethylcellulose (co)polymer (A2) soluble in fluids of the gastrointestinal tract; plasticizing polyvinylpyrrolidone (A3); castor oil/optionally a surfactant and/or magnesium stearate lubricant (A4). B comprises a hydrophilic polymer (B1) bearing ionized groups with neutral pH (EUDRAGIT® L100-55) and a hydrophobic compound (B2) (LUBRITAB®). The invention also concerns medicines based on said microparticles.

Die Erfindung betrifft ein Präparat zur Applikation von Wirkstoffen in Form kleinster, insbesondere mit einer membranartigen Hülle aus einer oder wenigen Lagen amphiphiler Moleküle bzw. mit einer amphiphilen Trägersubstanz versehenen Flüssigkeitströpfchen, insbesondere zum Transport des Wirkstoffes in und durch natürliche Barrieren und Konstriktionen wie Häute und dergleichen. Das Präparat weist einen Gehalt einer randaktiven Substanz auf, der bis zu 99 Mol.-% des Gehaltes dieser Substanz entspricht, durch den der Solubilisierungspunkt der Tröpfchen erreicht wird. Das Präparat eignet sich zur nichtinvasiven Verabreichung von Antidiabetica, insbesondere von Insulin. Die Erfindung betrifft außerdem ein Verfahren zur Herstellung solcher Präparate.
