Abstract

Abstract Translated from German Arzneimittelhaltiges Trägersystem zur peroralen Anwendung in Form einer ultrafeinen Suspension von Lipidnanopellets bestehend aus Lipiden mit oberflächenaktiven Mitteln, deren Teilchendurchmesser 50-1'000 Nanometer, vorzugsweise 80-800 Nanometer beträgt, wobei das Verhältnis von Lipid zu grenzflächenaktiven Stoff in den Lipidnanopellets 1:0,01 bis 1:2,2, vorzugsweise 1:0,22 bis 1:1,2, insbesondere 1:1 bis 1:0,22 beträgt und die Lipidteilchen in der Suspension in einer Konzentration von 1-20 Gew.-% vorliegen. Die Lipidnanopellets lassen sich mit pharmakologisch aktiven Substanzen beladen, so daß eine verbesserte Bioverfügbarkeit möglich ist. Drug-containing carrier system for oral use in the form of an ultrafine suspension of lipid nanopellets consisting of lipids with surface-active agents, the particle diameter of which is 50-1,000 nanometers, preferably 80-800 nanometers, the ratio of lipid to surfactant in the lipid nanopellets being 1: 0. 01 to 1: 2.2, preferably 1: 0.22 to 1: 1.2, in particular 1: 1 to 1: 0.22 and the lipid particles are present in the suspension in a concentration of 1-20% by weight . The lipid nanopellets can be loaded with pharmacologically active substances, so that an improved bioavailability is possible.
