Abstract

Oppfinnelsen vedrorer et system til fortrinnsvis peroral administrering med erosjonsregulert aktivt middelfrlgjørlng og en fremgangsmåte for dens fremstil- ling som fortrinnsvis lavoppløsellge aktive midler blir frigjort med forsinkelse, og 1 en mulig kombinasjon av hensiktsmessige, høyoppløselige aktive midler blir sistnevnte frigjort raskt og med bare liten for- sinkelse. Det aktive mldlet(ene) blir fremstilt på en vanlig måte med hjelpestoffer som har evne til Evelling, f.eks. mikrokrystallinsk cellulose eller stivelse, med hjelpestoffer som har høyere affinitet til vann og fungerer som svelleregulatorer (f.eks. polyetylenglykoler, sterkt hydratlserende uorganiske forbindelser) og valgfritt med ytterligere hjelpe- stoffer. De farmasøytiske fremstillingene fremstilt på denne måten bidrar betydelig i å forbedre terapien med forskjellige sykdommer, for når passende og fortrinns- vis lavoppløsellge aktive midler blir inkorporert, blir Justering og opprettholdelse av terapeutisk effektive konsentrasjoner med aktivt middel sikret.
