Description
Die Erfindung betrifft den in den Ansprüchen 1 bis 7 bebeschriebenen Gegenstand. The invention relates to the subject matter described in claims 1 to 7.
Die erfindungsgemässen Arzneiformen sind Manteltabletten, deren Kern den Wirkstoff m-Hydroxy-a-(äthyl-aminomethyl)-benzylalkohol (Etilefrin) vorzugsweise in Form von dessen pharmazeutisch annehmbaren Salzen, bei-5 spielsweise dem Hydrochlorid oder Sulfat, enthält. The pharmaceutical forms according to the invention are coated tablets, the core of which contains the active ingredient m-hydroxy-a- (ethylaminomethyl) benzyl alcohol (etilefrin), preferably in the form of its pharmaceutically acceptable salts, for example the hydrochloride or sulfate.
Aus der belg. Patentschrift 854 694 ist es bekannt, eine Kombination von Verbindungen der Formel I bzw. deren pharmazeutisch annehmbaren Salzen und m-Hydroxy-a-(äthyl-amino-methyl)-benzylalkohol (Etilefrin) bzw. dessen io pharmazeutisch annehmbaren Salzen zur Verbesserung des Venentonus beispielsweise zur Behandlung von niederem Blutdruck und Orthostase zu verwenden. Hierbei wurde tert. Butyl in Stellung 6 des Ergopeptin-Ringsystems nicht beansprucht, nachdem für Verbindungen dieser Struktur eine i5 günstige Wirkung bei der Kombination nicht zu erwarten ist. Der gleiche Disclaimer gilt auch für die vorliegende Erfindung. From the Belgian patent 854 694 it is known to combine compounds of the formula I or their pharmaceutically acceptable salts and m-hydroxy-a- (ethylamino-methyl) benzyl alcohol (etilefrin) or its io pharmaceutically acceptable salts To improve venous tone, for example, to treat low blood pressure and orthostasis. Here was tert. Butyl in position 6 of the ergopeptin ring system is not claimed, since an i5 beneficial effect in the combination is not expected for compounds of this structure. The same disclaimer also applies to the present invention.
Die vorliegende Erfindung betrifft eine spezielle Verabreichungsform dieser bekannten Kombination. The present invention relates to a special administration form of this known combination.
20 Neben dem Wirkstoff befinden sich im Kern pharmazeutische Hilfsstoffe, die eine verzögernde Wirkung auf die Freigabe des Wirkstoffes besitzen, vorzugsweise Acrylharze (EUDRAGIT RS 100) und Calciumarachinat. Ferner können noch pharmazeutische, die Wirkstofffreisetzung verzö-25 gernde Füll- und Trägerstoffe, beispielsweise Calciumsalze wie Calciumsulfat oder Calciumhydrogenphosphat, und übliche Hilfsstoffe wie Maisstärke und Talk anwesend sein. 20 In addition to the active ingredient, the core contains pharmaceutical excipients that have a delaying effect on the release of the active ingredient, preferably acrylic resins (EUDRAGIT RS 100) and calcium arachinate. Furthermore, pharmaceutical fillers and carriers which delay the release of the active ingredient, for example calcium salts such as calcium sulfate or calcium hydrogen phosphate, and customary auxiliaries such as corn starch and talc may also be present.
Zur Befilmung verwendet man zweckmässigerweise Cel-luloseätherderivate wie Hydroxypropylmethylcellulose, 30 Ethocel, Methocel usw. For filming it is expedient to use cellulose ether derivatives such as hydroxypropylmethyl cellulose, 30 Ethocel, Methocel etc.
Das im Tablettenmantel befindliche wirkstoffhaltige Gemisch enthält als Wirkstoffe die Verbindungen der Formel I, insbesondere Dihydroergotamin, vorzugsweise in Form ihrer pharmazeutisch annehmbaren Salze, beispielsweise der 35 Methansulfonate, Maleate oder Tartrate. Überdies enthält der Tablettenmantel übliche pharmazeutische Zusätze, beispielsweise Bindemittel wie Polyvinylpyrrolidon, Gleitmittel wie Talk, Sprengmittel wie Maisstärke und weitere Zusätze wie Siliciumdioxid und Cellulose. The active ingredient-containing mixture contained in the tablet coat contains as active ingredients the compounds of the formula I, in particular dihydroergotamine, preferably in the form of their pharmaceutically acceptable salts, for example the methanesulfonates, maleates or tartrates. In addition, the tablet casing contains customary pharmaceutical additives, for example binders such as polyvinylpyrrolidone, lubricants such as talc, disintegrants such as corn starch and other additives such as silicon dioxide and cellulose.

Beispiel: Example:
Herstellung einer 2-Schichten-Manteltablette a) Herstellung des Tablettenkernes Production of a 2-layer coated tablet a) Production of the tablet core
16,2 kg Etilefrin Hydrochlorid werden mit 34,0 kg wasser-45 freiem Calciumhydrogenphosphat, 9,72 kg Maisstärke, 6,48 kg Calciumarachinat, 16,2 kg Talkum und 8 g LB-Pigment rotbraun zu einer homogenen Pulvermischung vermischt. Diese Pulvermischung wird mit einer Lösung von 12,96 kg Eudragit RS 100 in einem 1 zu 1 Gemisch von so Äthanol und Dichlormethan durchfeuchtet, anschliessend granuliert und dann getrocknet. Das trockene Granulat wird mit 3,24 kg Calciumarachinat und 2,43 kg Talkum zur Tablettenmasse aufgemischt und mit Hilfe einer üblichen Tablettenpresse zu Tabletten mit einem Gewicht von 125 mg 55 Gewicht verpresst. 16.2 kg of Etilefrin hydrochloride are mixed with 34.0 kg of water-45-free calcium hydrogen phosphate, 9.72 kg of corn starch, 6.48 kg of calcium arachinate, 16.2 kg of talc and 8 g of LB pigment red-brown to form a homogeneous powder mixture. This powder mixture is moistened with a solution of 12.96 kg of Eudragit RS 100 in a 1 to 1 mixture of such ethanol and dichloromethane, then granulated and then dried. The dry granules are mixed with 3.24 kg of calcium arachinate and 2.43 kg of talc to give the tablet mass and pressed into tablets with a weight of 125 mg 55 by means of a conventional tablet press.
b) Beschichtung des Tablettenkernes b) coating of the tablet core
405 g Hydroxypropylmethylcellulose E 15 werden vollständig in demineralisiertem Wasser gelöst. Die unter a) her-60 gestellten Tablettenkerne (101,25 kg) werden in einem geeigneten Beschichtungsapparat vorgewärmt und nach und nach mit der Filmlösung überzogen. Nach Beendigung des Sprühvorganges werden die befilmten Tablettenkerne vorgetrocknet, 300 g Talkum eingestreut und über Nacht getrocknet. 405 g of hydroxypropylmethylcellulose E 15 are completely dissolved in demineralized water. The tablet cores (101.25 kg) produced under a) -60 are preheated in a suitable coating apparatus and gradually coated with the film solution. When the spraying process has ended, the coated tablet cores are predried, 300 g of talc are sprinkled in and dried overnight.
