1. Förfarande för framställning av ett peroralt tera-peutiskt system för givning av i vatten svärlösliga aktiva ämnen, förutom karbamazepin, vilket system bestär av a) en mantel, vilken är vattenpermeabel och opermeabel för komponenterna i en kärna, vilken innehäller det aktiva ämnet, b) en kärna, som innehäller det i vatten svärlösliga aktiva ämnet eller en kombination av aktiva ämnen, ett hyd-rofilt, polymeriskt svällningsmedel, som bestär av en blandning av vinylpyrrolidon-vinylacetat-kopolymerisat och etylenoxidhomopolymerisat, eventuellt ett vattenlös-ligt medel för att ästadkomma osmos och eventuellt andra farmaceutiskt godtagbara hjälpmedel, och c) en genomgäng genom mäntein a) för transport av kärnans komponenter in i en omgivande vattenhaltig kroppsvätska, kannetecknat därav, att komponenterna i kärnan b) blandas med varandra och komprimeras tillsammans, denna kärna b) beläggs med mäntein a) och genomgängen c) bildas i mäntein.
2. Förfarande enligt patentkravet 1 för framställning av ett peroralt terapeutiskt system, som bestär av a) en mantel, vilken är vattenpermeabel och för komponenterna i kärnan, som innehäller det aktiva ämnet, samt för mag- eller tarmsaftjonera opermeabel acylerad cellulosa, b) en kärna, som innehäller det i vatten svärlösliga aktiva ämnet eller en kombination av aktiva ämnen, en 1:1-blandning (vikt) av vinylpyrrolidon-vinylacetat-kopolymerisat och etylenoxidhomopolymerisat, natrium-eller kaliumklorid för att ästadkomma osmos och eventuellt andra farmaceutiskt godtagbara hjälpmedel, och c) en genomgäng genom mäntein a) för transport av kärnans komponenter in i den omgivande vattenhaltiga kroppsväts-kan, kannetecknat därav, att komponenterna i kärnan b) 92648 blandas med varandra och komprimeras tillsammans, denna kärna b) beläggs med mäntein a) och genomgängen c) bildas i mäntein.
3. Förfarande enligt patentkravet 1 för framställning av ett peroralt terapeutiskt system i tablettform, vilken bestär av a) en mantel, som är vattenpermeabel och för komponenter-na i kärnan, som innehäller det aktiva ämnet, samt för mag- och tarmsaftjonerna opermeabel acylerad cellulosa, b) en kärna, som innehäller det i vatten svärlösliga aktiva ämnet eller en kombination av aktiva ämnen, en 1:1-blandning (vikt) av vinylpyrrolidon-vinylacetat-kopolyme-risat, vars molekylvikt är 60000 + 15000 och monomerför-hällande ca. 60:40 (vikt-%), och etylenoxidhomopolymeri-sat, vars polymeriseringsgrad är 2000-100000, och c) en genomgäng genom mäntein a) för transportering av kärnans komponenter in i den omgivande vattenhaltiga kroppsvätskan, kännetecknat därav, att komponenterna i kärnan b) blandas med varandra och komprimeras tillsammans, denna kärna b) beläggs med mäntein a) och genomgän-gen c) bildas i mäntein.
