Baggrund
\n<\/span><\/strong>Mange retningslinjer anbefaler seponering af benzodiazepiner og Z-drugs (ikke-benzodiazepine sovemidler som fx zolpidem og zopiclon) hos langtidsbrugere. Fysisk afh\u00e6ngighed kan dog opst\u00e5 selv ved<\/span> korrekt brug som ordineret, og udtrapning kan derfor v\u00e6re vanskelig og forbundet med sv\u00e6re og langvarige abstinenssymptomer, s\u00e6rligt efter lang tids behandling.<\/span><\/p>\n

Form\u00e5l
\n<\/span><\/strong>Artiklen har til form\u00e5l at beskrive de farmakologiske principper bag sikker dosisreduktion af benzodiazepiner og Z-drugs samt at belyse, hvordan udtrapning kan tilrettel\u00e6gges, s\u00e5 ubehag og abstinenssymptomer mindskes.<\/span><\/p>\n

Metode
\n<\/span><\/strong>Artiklen er en farmakologisk analyse, der sammenholder eksisterende anbefalinger om line\u00e6r og proportionel dosisreduktion med sammenh\u00e6ngen mellem dosis og aktivitet p\u00e5 GABA-A-receptorer.<\/span><\/p>\n

Resultater
\n<\/span><\/strong>Forfatterne beskriver, at forholdet mellem dosis og aktivitet p\u00e5 hjernens receptorer (GABA-A) er hyperbolsk: kurven stiger stejlt ved lave doser og flader ud ved h\u00f8jere doser. Line\u00e6re dosisreduktioner medf\u00f8rer derfor gradvist st\u00f8rre \u00e6ndringer i graden af receptorbinding og dermed forventeligt mere udtalte abstinenssymptomer, mens hyperbolske eller proportionelle reduktioner giver mere line\u00e6re \u00e6ndringer i den farmakologiske effekt. <\/span><\/p>\n

Langsom udtrapning over m\u00e5neder eller \u00e5r kan v\u00e6re mere succesfuld end hurtig udtrapning over dage eller uger, og tempoet b\u00f8r justeres efter abstinenssymptomernes sv\u00e6rhedsgrad. For nogle patienter vil slutdoserne skulle v\u00e6re meget sm\u00e5 og ligge langt under de mindste tabletstyrker p\u00e5 markedet (svarende til omkring 0,2 mg i diazepam\u00e6kvivalent eller mindre), for at det sidste spring til nul ikke bliver st\u00f8rre end de foreg\u00e5ende trin. Flydende eller special-fremstillede l\u00e6gemidler i sm\u00e5 styrker (magistrelt fremstillede) kan derfor v\u00e6re n\u00f8dvendige (se<\/span> dk.taperingstrip.com<\/a>)<\/span><\/p>\n

Konklusion
\n<\/span><\/strong>Forfatterne anbefaler, at kliniske retningslinjer b\u00f8r underst\u00f8tte hyperbolsk udtrapning, mens der afventes randomiserede studier, som direkte sammenligner line\u00e6r og hyperbolsk dosisreduktion.<\/span><\/p>\n

Implikationer for praksis
\n<\/span><\/strong>Artiklen peger p\u00e5, at udtrapning b\u00f8r planl\u00e6gges individuelt og med gradvist mindre dosisreduktioner, jo lavere dosis patienten n\u00e5r ned p\u00e5. I klinisk praksis indeb\u00e6rer det behov for t\u00e6t monitorering af abstinenssymptomer, fleksibel tilpasning af tempoet og i nogle tilf\u00e6lde brug af styrker, der muligg\u00f8r meget sm\u00e5 dosisreduktioner.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
