Description
DK 175752 B1
Den foreliggende opfindelse angår et vandigt, oralt farmaceutisk diclofenacpræparat samt en fremgangsmåde til fremstilling deraf.
> 5 Diclofenac med den kemiske betegnelse o-( 2,6-dichlorani- 1 ino) -phenyleddikesyre er et kendt kraftigt analgetikum og antirheumatikum og er eksempelvis beskrevet i US-patent-skrift nr. 3.558.690.
10 Der er gjort mange forsøg på at udvikle en vandig, individuel doserbar oral indgiftsform for dette virksomme stof. Den tilstræbte indgiftsform skal have en neutral eller behagelig smag og desuden have en tilfredsstillende lagerstabilitet, således at læger samt patienter får 15 mulighed for at anvende et hensigtsmæssigt alternativ til andre orale præparater.
Det er kendt, at diclofenac har en bitter smag og fremkalder en kradsende fornemmelse i halsen. Det er endvidere 20 en ulempe, at der ved dannelse af sædvanlige vandige orale opløsninger dannes tungtopløselige hydrater, der medfører udfældninger. Desuden er det kendt, at diclofenac især i sur opløsning cycliserer til l-(2,6-dichlorphenyl)-indo-lin-2-on. Tilsvarende vandige farmaceutiske diclofenac-.
25 formuleringer har derfor ikke tilstrækkelige lagerstabilitet og ville følgelig ikke opfylde kriterierne for registrering som lægemiddel.
Det er formålet med den foreliggende opfindelse at til-30 vejebringe et vandigt oralt farmaceutisk diclofenacpræparat, som ikke har de ovenfor omtalte ulemper.
Dette opnås med præparatet ifølge opfindelsen, der er ejendommeligt ved, at diclofenac foreligger i et pH-35 område på 2-3,5.

I 1 I
I Ved anvendelse af sådanne vandige formuleringer eller I
I præparater har overraskende vist sig, at der især ikke I
I konstateres nogen prohibitiv indolinondannelse. Endvidere I
har sådanne præparater en behagelig smag og fremkalder I
5 ingen kradsende fornemmelse i halsen. I
Den foretrukne koncentration af aktivt stof i præparatet I
ifølge opfindelsen ligger mellem 0,5 og 10 vægt-%, især I
I mellem 1 og 5 vægt-%, forst og fremmest ved 1 vægt-%; I
B 10 I
Det her omhandlede pH-områ de ligger imellem 2 og 3,5, I
I fortrinsvis mellem 2,5 og 3,5, og det indstilles ved hjælp I
af kendte, farmaceutisk anvendelige syrer eller puffer- I
systemer. Som farmaceutiske anvendelige syrer kan I
15 eksempelvis nævnes carboxylsyrer, såsom eddikesyre, I
malonsyre, furmarsyre, maleinsyre, ravsyre, mælkesyre, I
vinsyre eller i første række citronsyre. Som eksempler på I
puffersystemer kan nævnes natriumcitrat/HCl-puffer eller I
citronsyre/phosphatpuffer. I
I 20 I
Tilsvarende applikationsformer for suspensionen ifølge I
opfindelsen er dråber, miksturer, saft eller sirup, som I
også kan anvendes på dosisenhedsform. I
25 De omhandlede præparater kan endvidere indeholde farma- I

10 Egnede antioxidationsmidler, som skal hæmme de oxidative processer, er eksempelvis sulfiter, såsom alkalimetalsul-fiter, -hydrogensulfiter eller -pyrosulfiter, f.eks. de tilsvarende natrium- eller kaliumsalte, thiodipropionsyre, thioglycol, thiomælkesyre, glutathion, fortrinsvis dog 15 cystein, ascorbinsyre og estere deraf, f.eks. ascorbin-syremyristat, -palmitat eller -stearat, eller gallussyre-estere, såsom galluspropyl-, -octyl- eller -dodecylester, f.eks. i en mængde på fra ca. 0,01 til ca. 0,1 vægt-%. Der kan eventuelt også anvendes synergister, såsom citronsyre, 20 citraconsyre, phosphorsyre eller vinsyre.
Til forbedring af smagen kan der som aromastoffer eksempelvis anvendes etheriske olier, især olier fra frugter, såsom appelsin-, pomerans-, mandarin- eller citronolie, og endvidere sukkerkulør.
25 Egnede farvestoffer er eksempelvis indigotin I (blå), amaranth (rød), gulorange S (orange), tartrazin XX (gul) eller chlorofyl (grøn).
Som sødemidler, der f.eks. i sirupper foreligger i høj koncentration, kan eksempelvis anvendes sukker, såsom 30 mono- eller disaccharider, f.eks. D-glucose, D-fructose, D-xylose, maltose eller saccharose, polyoler, såsom glycerol, dulcitol, mannitol, sorbitol eller xylitol, eller kunstigesødestoffer, såsom saccharin eller det tilsvarende natrium-, kalium- eller calciumsalt, cyclamat

De omhandlede vandige orale farmaceutiske diclofenacpræ-parater fremstilles afhængigt af applikationsformen eksempelvis som beskrevet i det følgende.
15 Fremgangsmåden ifølge opfindelsen er ejendommelig ved, at man suspenderer diclofenac i vand, indstiller pH-værdien ved hjælp af syre eller et puffersystem og eventuelt tilblander farmaceutisk anvendelige hjælpe- og tilsætningsstoffer 20
Man kan eksempelvis starte med at indarbejde hjælpe- og tilsætningsstofferne i vandet eventuelt under opvarmning, f.eks. i et temperaturområde fra ca. 20 til ca. 100°C. I dette grundlag suspenderes derefter det aktive stof. Blan-22 dingsrækkefølgen for komponenterne i præparatet ifølge opfindelsen er dog ikke kritisk.
Til fremstilling af sirupper sættes eksempelvis suspensionsmidlet og den tilsvarende suspensionsstabilisator til 2Q vandet. Derefter indarbejdes sødemiddel samt eventuelt konserveringsmiddel, antioxidanter, aromastoffer og/eller j farvestoffer, eventuelt under opvarmning, f.eks. i et tem peraturområde fra ca. 50 til ca.lOO’C. Derpå suspenderes det aktive stof i mediet.
Det omhandlede vandige orale farmaceutiske præparat kan eksempelvis anvendes til behandling af smertetilstande og inflammatoriske processer.
