Abstract
Description
Die Anwendung von Medikamenten erfolgt bisher oral, rektal, subku tan oder über die Blutgefäße. All diese Anwendungen haben die bei den Nachteile, daß das Medikament sich über den ganzen Körper ver teilt und dadurch (1) unerwünschte Nebenwirkungen an Körperteilen oder Organen verursacht, obwohl das Medikament an diesen Orten, wo die unerwünschten Nebenwirkungen entstehen, gar nicht benötigt wird, und daß (2) höhere Mengen des Medikamentes benötigt werden, um an der gewünschten Körperstelle oder am gewünschten Organ eine ausreichende Menge des Wirkstoffes zur Verfügung zu haben.So far, medication has been used orally, rectally, subcutaneously tan or through the blood vessels. All of these applications have the the disadvantages that the drug ver over the whole body shares and thereby (1) undesirable side effects on parts of the body or organs, although the drug is in these places where the undesirable side effects arise, not needed at all and that (2) higher amounts of the drug are needed, in order to achieve a desired position on the body or organ to have a sufficient amount of the active ingredient available.
Für viele Medikamentenanwendungen wäre es ideal, wenn der Wirk stoff unmittelbar nur an der gewünschten Stelle im Körper ange wandt werden könnte und die übrigen Körperteile und Organe nicht erreichte, denn dadurch könnten schädliche Nebenwirkungen an den übrigen Körperteilen oder Organen vermieden werden, und die erfor derliche Menge des oft sehr teuren Medikamentes könnte wesentlich reduziert werden, da eben nur die für die Anwendung an dem betrof fenen Körperteil oder Organ erforderliche Menge benötigt wird und das Medikament nicht über den ganzen Körper verteilt würde.For many drug applications, it would be ideal if the effect directly attached to the desired location in the body could be turned and the other parts of the body and organs can not achieved because this could cause harmful side effects to the other parts of the body or organs are avoided, and the requ Such amount of the often very expensive drug could be significant can be reduced, since only those for use on the affected the required part of the body or organ is required and the drug would not spread all over the body.
In der Medizin wird dieses Ziel teilweise dadurch erreicht, daß die Injektionen in bestimmte Körperteile erfolgen oder aber, daß Medikamente in Kapseln eingenommen werden, die sich erst nach ei ner bestimmten Zeit, und damit näher an dem gewünschten Körper teil, auflösen. All diese Verfahren haben aber den verbleibenden Nachteil, daß das Medikament sich nach der Anwendung frei über den Körper verteilt und damit an nicht gewünschten Stellen wirkt und so unverändert die zuvor beschriebenen Nachteile auslöst.In medicine, this goal is partially achieved by: the injections into certain parts of the body or that Medicines are taken in capsules that only take after an egg a certain time, and thus closer to the desired body part, dissolve. However, all of these methods have the remaining one Disadvantage that the drug is free after use Body distributed and thus acts in unwanted places and so unchanged triggers the disadvantages described above.
Erfindungsgemäß wird ein Verfahren zur lokalen Anwendung von Medi kamenten vorgeschlagen, das dadurch gekennzeichnet ist, daß das Medikament zwischen einer Anode und einer Kathode eingebracht wird mit der Folge, daß die Ausbreitung des Medikamentes sich auf den Bereich zwischen Anode und Kathode begrenzt und es dadurch möglich ist, die Wirkung des Medikamentes auf ganz bestimmte enge Körper bereiche zu begrenzen. Hierdurch werden Nebenwirkungen in allen anderen Körperbereichen ausgeschlossen, weil dort kein Wirkstoff hingelangt, und die erforderliche Menge des für die Behandlung er forderlichen Medikamentes kann wesentlich reduziert werden, da nur so viel einzusetzen ist, wie zu der gezielten Anwendung eben er forderlich ist. According to the invention, a method for the local application of medi came proposed, which is characterized in that the Medicament is introduced between an anode and a cathode with the result that the spread of the drug affects the Area between anode and cathode is limited, making it possible is the effect of the drug on certain tight bodies limit areas. This will cause side effects in all other areas of the body excluded because there is no active ingredient got there, and the amount required for treatment he required medication can be significantly reduced because only as much is to be used as for the targeted application is required.
Die oben beschriebene Wirkung wird dadurch erzielt, daß bei Anle gung einer schwachen Spannung zwischen der Anode und Kathode zunächst im Körper ein schwacher elektrolytischer Vorgang abläuft und die Moleküle des Medikamentes sich ebenfalls elektrolytisch in dem Feld zwischen Anode und Kathode bewegen.The effect described above is achieved in that with Anle weak voltage between the anode and cathode First, a weak electrolytic process takes place in the body and the drug's molecules also electrolytically move the field between the anode and cathode.
Hierzu ist erforderlich, in den beiden entgegengesetzten Enden des zu behandelnden Körperteils mittels einer dünnen Nadel eine Anode und eine Kathode einzuführen und dann durch eine weitere dünne Ka nüle das Medikament in das Gewebe zwischen Anode und Kathode ein zuspritzen, wobei selbstverständlich die erforderliche Spannung angelegt sein muß.This is required in the two opposite ends of the an anode using a thin needle and insert a cathode and then through another thin Ka cannulate the drug into the tissue between the anode and cathode inject, of course, the required voltage must be created.
Ein erfolgversprechendes Beispiel für die Anwendung des hier be schriebenen Verfahrens ist die bisher übliche Behandlung von Krebstumoren mit teuren Zytostatika, bei der nicht nur der Tumor, sondern eine Vielzahl von anderen Geweben, mit z. T. sehr toxischen Nebenwirkungen, angegriffen werden. Werden entsprechend dem Erfin dungsgedanken an den beiden Enden des Tumors über dünne Nadeln eine Anode und eine Kathode eingeführt und mit Hilfe dieser ein elektrisches Feld erzeugt, so kann das mittelbar in den Tumor ge spritzte Zytostatika in seiner Auswirkung auf den Bereich zwischen den beiden Elektroden begrenzt werden und damit erreicht werden, daß die Zytostatika nur im gewünschten Bereich, nämlich im Tumorbereich wirken, so daß in anderen Geweben keine schädlichen Nebenwirkungen entstehen. Gleichzeitig wird die erforderliche Menge des zur Behandlung erforderlichen Zytostatikas wesentlich reduziert. Dieses ist insbesondere wichtig bei sehr teuren Medika menten, wie Interleukine o. a., die bei der Tumorbehandlung zur An wendung kommen.A promising example of the application of the be here written procedure is the usual treatment of Cancer tumors with expensive cytostatics, in which not only the tumor, but a variety of other fabrics, with z. T. very toxic Side effects to be attacked. According to the inven Thought at both ends of the tumor via thin needles an anode and a cathode are inserted and with the help of this one generated electric field, so it can ge in the tumor injected cytostatics in its impact on the area between the two electrodes are limited and thus achieved that the cytostatics only in the desired range, namely in Tumor area act so that no harmful in other tissues Side effects arise. At the same time, the required The amount of cytostatic agent required for treatment is essential reduced. This is particularly important for very expensive medicines elements, such as interleukins or the like, which are used in tumor treatment turn come.
