Abstract
Description
Für die pharmazeutische Verarbeitung von pflanzlichen Drogen werden hauptsächlich Flüssig-Extrakte (Fluid-Extrakte bzw. Tinkturen), Dickextrakte (Spissum-Extrakte) und Trockenextrakte (Siccum-Extrakte) verwendet.For the pharmaceutical processing of herbal drugs mainly liquid extracts (fluid extracts or Tinctures), thick extracts (spissum extracts) and dry extracts (Siccum extracts) used.
Wie in den meisten Arzneibüchern beschrieben, wird für die Herstellung von Flüssig-Extrakten in der Regel als Auszugs mittel eine wäßrig-äthanolische Mischung verwendet.As described in most pharmacopoeias, for Production of liquid extracts usually as an extract medium used an aqueous ethanol mixture.
Da viele Drogen medizinisch wirksame flüchtige Bestand teile enthalten, bestehen zwischen halbfesten bzw. Trocken- Extrakten und einem aus der gleichen Droge hergestellten Flüssig-Extrakt erhebliche Unterschiede in der phytoche mischen Zusammensetzung.Because many drugs are medically effective volatile parts included, exist between semi-solid or dry Extracts and one made from the same drug Liquid extract significant differences in phytoche mix composition.
Nach den herkömmlich angewandten Verfahren geht ein Großteil der flüchtigen Drogenbestandteile bei der Herstellung zu Trocken- bzw halbfesten Extrakten verloren. Somit sind klinisch-pharmakologische Aussagen, welche mit äthanolhal tigen Flüssig-Extrakten gewonnen wurden, nicht immer ohne weiteres auf Präparate von Trocken- bzw. Dick-Extrakten zu übertragen.The majority of the processes are based on the conventional methods of volatile drug components in manufacturing Dry or semi-solid extracts lost. So are clinical-pharmacological statements, which with ethanol liquid extracts, not always without further on preparations of dry or thick extracts transfer.
Daher ist ein Verfahren hocherwünscht, welches die Herstel lung von Dick- bzw. Trocken-Extrakten erlaubt, wo die flüchtigen Bestandteile praktisch nicht verloren gehen. Therefore, a method which the manufacturer Thick or dry extracts allowed where the volatile components are practically not lost.
Extrakte mit solchen Eigenschaften würden es erlauben, feste Arzneiformen, wie Tabletten, Kapseln (Hart- und Weichgelatine- Kapseln), Granulate, zu entwickeln, wo die klinisch-pharma kologische Wirksamkeit mit der einer äthanolhaltigen Flüssig- Extrakt-Arzneiform vergleichbar ist.Extracts with such properties would allow them to be solid Dosage forms, such as tablets, capsules (hard and soft gelatin Capsules), granules, develop where the clinical pharma ecological effectiveness with that of a liquid containing ethanol Extract drug form is comparable.
Feste Darreichungsformen haben insbesondere bei Drogen mit schlechtem Geschmack einen erheblichen Compliance-Vorteil gegenüber flüssigen Zubereitungen, da oft auf Grund der schlechten Compliance die Therapie vorzeitig vom Patienten abgebrochen wird. Außerdem sind diese Darreichungsformen im Gegensatz zu den Flüssig-Extrakt-Zubereitungen äthanolfrei, was insbesondere vorteilhaft ist für die Anwendung bei Alkoho likern und Kindern.Fixed dosage forms are particularly important for drugs bad taste has a significant compliance advantage compared to liquid preparations, because of the poor compliance the therapy prematurely from the patient is canceled. In addition, these dosage forms are in the In contrast to the liquid extract preparations, free of ethanol, which is particularly advantageous for use in alcohol likers and children.
Somit könnte den WHO-Empfehlungen voll entsprochen werden. Ein solcher Dick- oder Fest-Extrakt erlaubte es auch, durch Auflösung in einem äthanolfreien Lösungsmittel, äthanolfreie Flüssigextrakte herzustellen.The WHO recommendations could thus be fully complied with. Such a thick or solid extract also allowed through Dissolution in an ethanol-free solvent, ethanol-free To produce liquid extracts.
Der vorliegenden Erfindung liegt ein solches hocherwünschtes Verfahren zugrunde, welches die Herstellung von Dick- bzw. Trockenextrakten erlaubt, welche in ihren Inhaltsstoffzusam mensetzungen mit einem aus der gleichen Droge hergestellten wäßrig-äthanolischen Flüssig-Extrakt vergleichbar sind.The present invention has such a highly desirable one Process based on the production of thick or Dry extracts allowed, which together in their ingredients resolutions with one made from the same drug aqueous-ethanolic liquid extract are comparable.
Überraschenderweise wurde gefunden, daß durch Abdestillieren des Äthanol-Wasser-Gemisches aus Flüssig-Extrakten und anschließender Extraktion des Destillates mit einem geeigneten Extraktionsmittel die flüchtigen Drogen-Bestandteile aus der Äthanol-Wasser-Phase praktisch vollständig extrahiert werden können.Surprisingly, it was found that by distillation of the ethanol-water mixture of liquid extracts and subsequent extraction of the distillate with a suitable one Extractant the volatile drug components from the Ethanol-water phase can be extracted almost completely can.
Nach dem Abtrennen der Extraktionsphase und anschließender Vereinigung derselben mit dem Destillationsrückstand, erhält man ggf.durch Zugabe von geeigneten Hilfsstoffen einen Dick- bzw. Trocken-Extrakt, mit dem praktisch gleichen Inhaltsstoff- Spektrum, wie im ursprünglichen Flüssig-Extrakt.After separation of the extraction phase and subsequent Union of the same with the distillation residue if necessary, a thick- or dry extract, with practically the same ingredient Spectrum as in the original liquid extract.
Bedingt durch die Eigenschaften des Extraktionsmittels und Zugabe von ggf. Hilfsstoffen, wie z. B. hochdispersem Silicium dioxid, kann verhindert werden, daß die flüchtigen Bestand teile bei der späteren Weiterverarbeitung zu Pharmazeutika in relevantem Ausmaß entweichen.Due to the properties of the extractant and Addition of auxiliary materials, if necessary, such as B. highly disperse silicon dioxide, can be prevented from volatile parts in later processing into pharmaceuticals relevant dimensions escape.
Als Extraktionsmittel werden physiologisch unbedenkliche Ester von ein- oder mehrwertigen Carbonsäuren, wie z. B. Fettsäuren (z. B. Stearinsäure, Myristinsäure u. a.), Adipinsäure u. a. mit ein- oder mehrwertigen Alkoholen, z. B. Äthanol, Isopropanol, Glycerin u. a. verwendet, einzeln oder in Mischungen.Physiologically harmless esters are used as extractants of mono- or polyvalent carboxylic acids, such as. B. fatty acids (e.g. stearic acid, myristic acid and others), adipic acid u. a. with mono- or polyhydric alcohols, e.g. B. ethanol, Isopropanol, glycerin and the like a. used individually or in Mixtures.
Als Hilfsstoffe zur weiteren Verarbeitung werden ggf. pharma zeutisch übliche Hilfsstoffe, einzeln oder in Mischungen, wie hochdisperses Siliciumdioxid, Stärke und Derivate, Cellulose und Derivate (auch quervernetzt), Poly(1-vinyl-2-pyrrolidon) und Derivate (auch quervernetzt), Einfach- und Mehrfachzucker, wie z. B. Saccharose, Lactose, Zucker-Alkohole, wie z. B. Mannit, Xylit, Sorbit, Polyäthylenglycol, wie z. B. Polyäthylenglycol 4000, Cyclodextrine, Propylenglycol, Carbonsäureester, physio logisch verträgliche Tenside, wie z. B. Polysorbate u. a. zuge geben, besonders bevorzugt hochdisperses Siliciumdioxid. Pharmaceuticals may be used as auxiliary substances for further processing typical auxiliary substances, individually or in mixtures, such as highly disperse silicon dioxide, starch and derivatives, cellulose and derivatives (also cross-linked), poly (1-vinyl-2-pyrrolidone) and derivatives (also cross-linked), single and multiple sugars, such as B. sucrose, lactose, sugar alcohols, such as.
