2-Amino-3-ethoxycarbonylamino-6-(p-fluorbenzylamino ) -pyridin-hydrochlorid er beskrevet i det tyske patentskrift 1 795 858. Denne forbindelse er antiflogistisk og analgesisk virksom. Til fremstilling 5 af farmaceutiske præparater er det i det tyske offentliggorelsesskrift DE 31 33 519.Al beskrevne 2-amino-3-ethoxycarbonylamino-6-(p-fluorbenzylamino)-pyridinmaleat egnet.
Til anvendelse af det aktive stof i form af en 10 oplosning er disse salte dârligt egnet pâ grund af de-res ringe oploselighed, dârlige stabilitet i oplosning og utilfredsstillende venose forligelighed.
Det tilsigtes derfor med opfindelsen at tilveje-bringe yderligere egnede tilberedningsformer for 2-ami-15 no-3-ethoxycarbonylamino-6-(p-fluorbenzylamino)-pyri-din, f.eks. injicerbare oplosninger.
Opfindelsen angâr 2-amino-3-ethoxycarbonylamino- 6-(p-fluorbenzylamino)-pyridin-gluconat med den kemiske formel: 20 ✓£Ss/IHCOOC2H5 F-^ ^-CH2“NH^N^^*NH2 *C6H12°7 25
Det har overraskende vist sig, at der ud fra 2-amino-3-ethoxycarbonylamino-6-(p-fluorbenzylamino)-pyridin-gluconat kan fremstilles stabile farmaceutiske præparater, især oplosninger. Det har endvidere vist sig, 30 at 2-amino-3-ethoxycarbonylamino-6-(p-fluorbenzylamino)-pyridin-gluconat ved intravenos indgivelse tâles bedre end de ovrige kendte salte af 2-amino-3-ethoxycarbonyl-amino-6-(p-fluorbenzylamino)-pyridin, idet det har bedre oploselighed og dermed venos forligelighed.

Premstillingen af 2-amino-3-ethoxycarbonylamino- 6-(p-fluorbenzylamino)-pyridin-gluconatet udfores ved 5 omsætning af 2-amino-3-ethoxycarbonylamino-6-(p-fluor-benzylamino)-pyridin med gluconsyre eller gluconsyre-6-lacton. Denne omsætning kan gennemfores med eller uden oplosningsmiddel ved temperaturer mellem 20 og 140°C, fortrinsvis 50 og 120°C.
10 Som oplosningsmiddel kommer f.eks. lavere alkoho- ler (f.eks. med 1-6 C-atomer, sâsom methanol, éthanol, n-propanol, isopropanol, n-butanol, 1,2-propandiol, 1,4-butandiol, n-pentanol, 3-pentanol, n-hexanol), lavere ketoner (f.eks. med 1-6 C-atomer, sâsom acetone, 2-buta-15 non, methylisobutylketon), polyalkylenglycoler (hvor al-kylen har 2,3 eller 4 C-atomer) med molekylvægte mellem 190 og 7500, og cykliske mættede alkoholer med 4 til 8, fortrinsvis 4 til 6 C-atomer, som f.eks. glycofurol samt farmaceutisk anvendelige organiske syrer og blan-20 dinger af disse midler med vand pâ taie.
Hvis man i stedet for gluconsyre anvender gluconsyre-6-lactonen, skal en vis mængde vand være til m stede (f.eks. 1 mol vand pr. 1 mol lacton. Det er f.eks. hensigtsmæssigt at anvende gluconsyre-6-25 lactonen, da den i handlen foreligger i krystallinsk form og hurtigt hydrolyseres til gluconsyre i vand. Fremstillingen kan f.eks. udfores pâ folgende mâde: 1 mol 2-amino-3-ethoxycarbonylamino-6-(p-fluor-benzylamino)-pyridin suspenderes eventuelt i et oplos-30 ningsmiddel (éthanol, 1,2-propandiol) og blandes med en oplosning af 1 mol gluconsyre-δ-lacton i et vandholdigt oplosningsmiddel (éthanol, 1,2-propandiol), fremstillet ved en temperatur mellem 20 og 140°C, eller med 1 mol gluconsyre med eller uden oplosningsmiddel. Man lader 35 reaktionsblandingen efterreagere i endnu nogen tid, fortrinsvis under opvarmning (50 til 70°C) og afdriver
DK 157016 B
3 dernæst eventuelt tilstedeværende opl0sningsmiddel.
Den tilbageblevne remanens inddampes derefter i alkohol og terres ved forhojet temperatur i vakuum.
Saltet udvindes i et udbytte pâ 90%. Smp. 117 5 til 123 °C.
2-Amino-3-ethoxycarbonylamino-6-(p-fluorbenzyl-amino)-pyridingluconatet er stabilt og udviser ingen tilbejelighed til farvning ved reaktion med den frie base eller ved oxidation, som det f.eks. kan iagttages 10 ved hydrochloridet.
2-Amino-3-ethoxycarbonylamino-6-(p-fluorbenzyl-amino)-pyridingluconatet er sâledes særlig velegnet til fremstilling af farmaceutiske præparater. Opfindelsen angâr derfor ogsâ lægemidler, der er ejendommelige ved 15 at de som aktivt stof indeholder 2-amino-3-ethoxycar- bonylamino-6-(p-fluorbenzylamino)-pyridin-gluconat sam-men med en sædvanlig farmaceutisk bærer og/eller et fortyndingsmiddel. 2-Amino-3-ethoxycarbonylamino-6-(p-fluorbenzylamino)-pyridingluconatet er tungt opleseligt 20 i vand, men ved tilsætning af en fysiologisk acceptabel organisk syre, f.eks. mælkesyre, glucuronsyre og/eHer gluconsyre, eges opleseligheden. Især ved tilsætning af overskydende gluconsyre oges oploseligheden væsentligt.
Til fremstilling af stabile, injicerbare oples-25 ninger af 2-amino-3-ethoxycarbonylamino-6-(p-fluorben zylamino ) -pyridingluconatet egner fysiologisk acceptable midler sig som oplosningsmiddel, f.eks. polyethylenglycol-vand-blandinger eller glycofurol-vand-blandinger og polyethylenglycol-glycofurol-vand-30 blandinger, eventuelt sammen med yderligere sædvanlige stabiliseringsmidler og hjælpestoffer. Fortrinsvis indeholder sâdanne oplosninger overskydende fri gluconsyre. Opfindelsen angâr ogsâ en fremgangsmâde til fremstilling af injicerbare oplosninger af 2-amino-3-etho-3 5 xycarbonylamino-6-(p-fluorbenzylamino)-pyridingluconat indeholdende fri gluconsyre, ved hvilken man blander 2-
DK 157016 B
4 amino-3-ethoxycarbonylamino-6-(p-fluorbenzylamino)-py-ridin eller 2-amino-3-ethoxycarbonylamino-6-(p-fluor-benzylamino)-pyridin-gluconat sammen med overskud af gluconsyre eller gluconsyre-ô-lacton i et fysiologisk 5 acceptabelt oplosningsmiddel.
For eksempel vælger man mindst l-gange, især 1-til 6-gange, fortrinsvis 2- til 4-gange molasrt overskud (pâ basis af 2-amino-3-ethoxycarbonylamino-6-(p-fluorbenzylamino)-pyridin-gluconatet) af gluconsyre.
10 Gluconsyren kan f.eks. fremstilles ved opvarm- ning af en vandig oplosning af gluconsyre-5-lacton til 60 til 70°C i mindst 30 minutter.
Gluconsyre-δ-lactonen foreligger i krystallinsk form, sâledes at det i almindelighed til udovelse af 15 opfindelsen er gunstigere, hver gang at fremstille gluconsyren ved hydrolyse af lactonen. Ved syretilsæt-ning fremkaldes en sur pH-værdi. Det anbefales i den fbrbindelse, at man ikke kommer under en pH-værdi pâ 2,0, da den ved venos anvendelse krævede forligelighed 20 herved forringes.
Oplesninger af 2-amino-3-ethoxycarbonylamino-6-(p-fluorbenzylamino)-pyridin-gluconatet i de angivne oplesningsmidler kan ogsâ fremstilles ved, at man blan-der 2-amino-3-ethoxycarbonylamino-6-(p-fluorbenzylami-25 no)-pyridin-gluconat med overskydende gluconsyre eller gluconsyre-δ-lacton og det pâgældende oplesningsmiddel (polyethylenglycol-vand, glycofurol-vand, polyethylenglycolglycofurol-vand), f.eks. ved omroring eller suspension ved en temperatur mellem 20 og 80°C 30 under nitrogengennemluftning.
I tilfælde af, at man i stedet for gluconsyre anvender gluconsyre-δ-lactonen, er tilstedeværelsen af vand nodvendig, nærmere bestemt 1 mol vand pr. mol gluconsyre- δ-lacton.
35 2-Amino-3-ethoxycarbonylamino-6-(p-fluorbenzyl amino ) -pyridin-gluconatoplosningerne ifolge opfindelsen
DK 157016 B
5 indeholder f.eks. 10 til 50, især 20 til 40, fortrins-vis 35 mg af den frie base pr. ml. For eksempel er indholdet af 2-amino-3-ethoxycarbonylamino-6-(p-fluor-benzyl-amino)-pyridin-gluconat i en injicerbar oplos-5 ning ca. 55 mg/ml.
Oplosningerne med et 3-gange eller 4-gange mo-lært overskud af gluconsyre har en pH-værdi pâ 3 til 4 og forbliver i klar oplosning ved syv dages opbevaring ved 7°C og dagslys og efter syv dages henstand i kole-10 skab ved 7°C uden krystaldannelse eller dannelse af uklarheder. Oplosningerne, fremstillet ifolge oplosnin-gen, udviser sâledes fordele i stabiliteten og den for-bedrede lagerholdbarhed.
Som oplosningsmidler kommer f.eks. polyethylen-15 glycol-vand-blandinger, som indeholder 10 til 95 vægt%, især 30 til 60 vægt%, fortrinsvis 40 vægt% polyethylen-glycol (den anvendte polyethylenglycol har fortrinsvis en gennemsnitlig molekylvægt pâ 200 til 600, især 300 til 400) eller glycofurol-vand-blandinger, som indehol-20 der 10 til 95 vægt%, især 40 vægt% glycofurol, pâ taie.
Ogsâ polyethylenglycol-glycofurol-vand-blandinger kommer pâ taie. En særlig foretrukken udforelsesform indeholder ca. 40 vægt% polyethylenglycol med en gennemsnitlig molekylvægt pâ ca. 400 og 60% vand eller 25 20 vægt% glycofurol og 80 vægt% vand.
Den ifolge opfindelsen anvendte polyethylenglycol har den almene formel:
H(OCH2CH2)nOH
og forhandles f.eks. som CARBOWAX eller LUTROL (se H.P.
30 Fiedler Editio Cantor Aulendorf, Lexikon der Hilfsstof-fe für Pharmazie, Kosmetik und angrenzende Gebiete 1981, side 726 ff).
Den polyethylenglycol, der kommer til anvendelse, kan f.eks. hâve folgende molekylvægtomrâde: 35
DK 157016 B
6 T A B E L 1
Polyethylenglycol Molekylvæqtomrâde 200 190 - 210 300 285 - 315 5 400 380 - 420 600 570 - 630 1000 950 - 1050 1540 1300 - 1600 4000 3000 - 4800 10 6000 5600 - 7500
Glycofurol ( tetrahydrofurfurylalkohol-polyethy-lenglycolether) har en molekylvægt pâ ca. 190 og en lav toksicitet og er derfor egnet som medium til injektions-15 oplosninger (R. Budden Arzneimittel-Forschung 28 (II), 1586 (1978)).
Dette oplosningsmiddel er ligeledes kommercielt tilgængeligt.
Injektionsopl0sningerne ifolge opfindelsen kan 20 desuden indeholde stabilisatorer og/eller antioxidanter, som f.eks. natriumfoisulfit, acetone-natriumbisulfit, ethylendlamintetraeddikesyre, ascorbinsyre og lignende.
Fortrinvis fyldes oplosningerne sterilt i stérile beholdere, f.eks. i ampuller. Midler til sterili-25 sering af disse oplosninger er kendt ifelge teknik-kens stade. Det foretrækkes at pâfylde oplosningerne under aseptiske betingelser og under steril nitroge-natmosfære i ampuller.
