VERWENDUNG VON LICHTAKTIVIERTEM INDOCYANINGRÜN ZUR BEHANDLUNG VON ENTZÜNDLICHEN KRANKHEITSZUSTÄNDEN IN DER MUNDHÖHLE USE OF LIGHT-ACTIVATED INDOCYANINGRENE FOR THE TREATMENT OF INFLAMMATORY DISEASE STATES IN THE MOUTH VALVE
Die Erfindung betrifft ein Verfahren zur Behandlung von insbesondere entzündlichem Krankheitszuständen in der Mundhöhle durch Einbringen einer von einer Lichtquelle aktivierbaren Substanz.The invention relates to a method for treating in particular inflammatory disease states in the oral cavity by introducing a substance which can be activated by a light source.
Stand der TechnikState of the art
Unter Photodynamische Therapie wird ein photochemisches Verfahren verstanden, das bisher vor allem in der Krebstherapie Anwendung fand. Unter diesem Begriff wird allgemein eine lichtinduzierte Inaktivierung von Zellen, Mikroorganismen oder Molekülen verstanden. Ein Wirkstoff heftet sich an die zu bekämpfenden Zellen an und wird dann durch Licht aktiviertPhotodynamic therapy is understood to mean a photochemical process which has hitherto been used primarily in cancer therapy. By this term is generally understood a light-induced inactivation of cells, microorganisms or molecules. An active substance attaches to the cells to be controlled and is then activated by light
BESTÄTIGUNGSKOPfE Eine Modifikation dieses Prinzip findet in der Bekämpfung von Mikroorganismen Anwendung - die „Antimikrobielle Photodynamische Therapie" (APT). Dabei ist das Ziel nicht die Vernichtung körpereigener (Tumor) - Zellen, sondern die gezielte Bekämpfung lokaler Infektionen, die Bekämpfung von Mikroorganismen. Das Wirkungsprinzip der APT beruht auf der selektiven Anfärbung der Mikroorganismen durch einen sogenannten Photosensitizer und der Zerstörung der Keime durch Belichtung mit einer geeigneten, auf den Photosensitizer abgestimmten Lichtquelle.confirmation head A modification of this principle is used in the control of microorganisms - the "antimicrobial photodynamic therapy" (APT) .The aim is not the destruction of the body's own (tumor) cells, but the targeted control of local infections, the fight against microorganisms The APT is based on the selective staining of the microorganisms by a so-called photosensitizer and the destruction of the germs by exposure to a suitable, matched to the photosensitizer light source.
Ein entsprechendes Verfahren ist aus der WO 01/87416 A1 bekannt. Mit Hilfe der lichtaktivierbaren Substanz, insbesondere eines Farbstoffes, werden die Mikroorganismen, sensibilisiert und/oder angefärbt und nach Bestrahlung mit Licht geeigneter Wellenlänge und Energiedichte abgetötet: Die mittels eines Bestrahlungsgeräts, insbesondere eines Lasergeräts, erzeugte Energie wird damit auf die Mikroorganismen konzentriert und die Gleichgewichtslage von Reaktionen, welche auch im nicht belichteten Zustand im „normalen" Milieu ablaufen, werden verschoben und in der Folge werden die Mikroorganismen zerstört.A corresponding method is known from WO 01/87416 A1. With the aid of the light-activatable substance, in particular a dye, the microorganisms are sensitized and / or stained and killed after irradiation with light of suitable wavelength and energy density: The energy generated by means of an irradiation device, in particular a laser device is thus concentrated on the microorganisms and the equilibrium position reactions that occur in the unexposed state in the "normal" milieu are postponed and as a result the microorganisms are destroyed.
Femer ist aus der EP 0 637 976 Bl die Verwendung einer lichtsensibilisierenden Substanz oder Verbindung bzw. eines Photosensitizers oder Photosensibilisators (PS) bei der Herstellung eines Medikamentes zur Verwendung bei der Desinfizierung oder Sterilisierung von Geweben der Mundhöhle oder einer Wunde oder Läsion in der Mundhöhle durch Zerstören von mit einer Erkrankung verbundenen Mikroben in einer periodontalen Tasche, in der Region zwischen dem Zahn und dem Zahnfleisch bekannt. Hierbei erfolgt eine Kontaktierung der Gewebe, der Wunde oder der Läsion mit dem Photosensitizer, wobei die mit der Erkrankung verbundenen Mikroben den Photosensitizer aufnehmen. Es wird eine Bestrahlung der Gewebe, der Wunde oder der Läsion mit Laserlicht bei einer durch den Photosensitizer absorbierenden Wellenlänge durchgeführt. Die Keimreduktion dieser kombinierten Farbstoff- und Laserbehandlung wird für verschiedene Keime und Photosensitizer in Form von Lösungen mit unter anderem Methylenblau und Toluidinblau beschrieben, wobei ferner der Einfluß der applizierten Energiedichte aufgezeigt wird. Als Lichtquellen werden HeNe-Laser sowie GaAs-Laser verwendet.Furthermore, EP 0 637 976 B1 discloses the use of a photosensitizing substance or compound or photosensitizer (PS) in the manufacture of a medicament for use in disinfecting or sterilizing tissues of the oral cavity or a wound or lesion in the oral cavity Destroying disease-related microbes in a periodontal pocket, known in the region between the tooth and the gums.

Aufgabetask
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren der o.g. Art zu entwickeln, bei dem ein geeigneter Wirkstoff Anwendung findet, der vor allem auch nach kurzer Zeit nicht mehr nachweisbar ist.The object of the present invention is to provide a method of the above-mentioned. To develop a type in which a suitable drug is used, which is especially after a short time no longer detectable.
Lösung der AufgabeSolution of the task
Zur Lösung der Aufgabe führt, dass die Substanz den Wirkstoff Indocyaningrün enthält und das Spektrum der Lichtquelle nennenswerte Anteile im Bereich von 700 — 1.000 nm emittiert.To achieve this object, the substance contains the active ingredient indocyanine green and the spectrum of the light source emits significant proportions in the range of 700-1,000 nm.
Indocyaningrün ist ein Infrarotfarbstoff, der in der medizinischen Diagnostik verwendet und unter dem Namen IR 125 als Laserfarbstoff eingesetzt wird. Es findet als intravenöses Diagnostikum mit einem breiten Spektrum in der Herz- Kreislauf-, Mikrozirkulations- und Leberfunktionsdiagnostik Anwendung und vor allem auch bei der Messung im Auge bzw. der Netzhaut.Indocyanine Green is an infrared dye used in medical diagnostics and used under the name IR 125 as a laser dye. It is used as an intravenous diagnostic agent with a broad spectrum in the cardiovascular, microcirculation and liver function diagnostics application and especially in the measurement in the eye or the retina.
Gemäss der vorliegenden Erfindung wird nun ein völlig neues Anwendungsgebiet eröffnet, welches nicht zu erwarten war, nämlich die Verwendung zur Behandlung von insbesondere entzündlichen Krankheitszuständen in der Mundhöhle im Zusammenwirken mit einer aktivierenden Lichtquelle. Die Substanz hat den grossen Vorteil, dass sie nach ca. drei Stunden nicht mehr nachweisbar ist.According to the present invention, a completely new field of application is now opened, which was not to be expected, namely the use for the treatment of, in particular, inflammatory disease states in the oral cavity in cooperation with an activating light source. The substance has the great advantage that it is no longer detectable after about three hours.
Als Lichtquelle sollen vor allem Halbleiterlaser (Diodenlaser) oder Licht emittierende Dioden (LED's) eingesetzt werden. Die eingesetzten Lichtquellen sollen bevorzugt Licht mit einer Wellenlänge im Bereich zwischen 780-830 nm emittiert. Die Ausgangsleistung der Lichtquelle liegt bevorzugt im Bereich zwischen 50 mW und 5.000 mW. Dies ergibt eine Bestrahlungsdosis zwischen 0,5 J — 50 J bei einer Belichtungsdauer von 10s - 100s.The main source of light is semiconductor lasers (diode lasers) or light emitting diodes (LEDs). The used Light sources should preferably emit light with a wavelength in the range between 780-830 nm. The output power of the light source is preferably in the range between 50 mW and 5,000 mW. This gives an irradiation dose of between 0.5 J-50 J at an exposure time of 10s-100s.
Bei der Applikation des Lichtes soll die Lichtquelle im Bereich zwischen 1.000 — 50.000 Hz, bevorzugt im Bereich zwischen 10.000 Hz — 20.000 Hz, gepulst werden. Dabei kann die Pause zwischen zwei Pulsen länger ist als die Pulszeit sein.When applying the light, the light source should be pulsed in the range between 1,000 and 50,000 Hz, preferably in the range between 10,000 Hz and 20,000 Hz. The pause between two pulses may be longer than the pulse time.
Die Substanz wird in steriler Darreichungsform appliziert. Ferner können der Substanz weitere Inhaltsstoffe hinzugefügt werden, die entzündliche Prozesse positiv beeinflussen.The substance is administered in sterile dosage form. Furthermore, the substance can be added to other ingredients that positively influence inflammatory processes.
Als Darreichungsform bietet es sich an, dass die Substanz in Form einer Mundspüllösung eine gewisse Zeit in der Mundhöhle verbleibt und die Belichtung des Wirkstoffs mit einer Lichtquelle nach dem Ausspülen des Wirkstoffs erfolgt. Dabei erfolgt die Belichtung des Wirkstoffs über eine Vorrichtung, welche die Lichtquelle enthält und temporär (z.B. während einer Arbeitspause oder über Nacht) getragen wird. Eine weitere Möglichkeit ist das Einbringen der Wirkstofflösung über eine entsprechende Applikationsvorrichtung, wie z.B. eine Spritze in schwer zugängliche Bereiche, wie Parodontaltaschen o.a.. As a dosage form, it is advisable that the substance in the form of a mouthwash solution remains in the oral cavity for a certain time and the exposure of the active substance to a light source takes place after rinsing out the active substance. The exposure of the drug is via a device that contains the light source and is worn temporarily (e.g., during a break or overnight). Another possibility is the introduction of the drug solution via a corresponding application device, such. a syringe in hard-to-reach areas, such as periodontal pockets or similar.
