Abstract

Det beskrives en kombinasjon av to forskjellige subenheter med forskjellige frigivningsprofiler i nye, orale doseringsformer for opprettholdt frigivning. Særlig inkluderer de orale doseringsformer en subenhet som omfatter et opioid analgetikum og et materiale for opprettholdt frigivning der oppløsningshastigheten in vitro for subenheten, målt ved standard USP Drug Release test i henhold til U.S. Pharmacopeia XXV1 (2003) <724> er mindre enn rundt 10 % innen rundt 6 timer og minst rundt 60 % innen rundt 24 timer; mindre enn rundt 10 % innen rundt 8 timer og minst rundt 60 % innen rundt 24 timer; mindre enn rundt 10 % innen rundt I 0 timer og minst rundt 60 % innen rundt 24 timer; eller mindre enn rundt 10 % innen rundt 12 timer og minst rundt 60 % innen rundt 24 timer; idet doseringsformen gir en varighet for den terapeutiske effekt på rundt 24 timer.
