Abstract
Verwendung einer Zusammensetzung, enthaltend40-60%Hydroxyethylenmethacrylat40-60%Phosphatdimethacrylat,0,1-1,0%Starter,zur Herstellung eines lichthärtenden Lackes zur Therapie der Onychomykose oder eines bakteriellen Nagelbefalls.Use of a composition containing 40-60% hydroxyethylene methacrylate, 40-60% phosphate dimethacrylate, 0.1-1.0% starter, for the production of a light-curing varnish for the therapy of onychomycosis or bacterial nail infestation.
Description
Die vorliegende Erfindung betrifft Zusammensetzungen zur Behandlung von Onychomykose, welche ohne einen klassischen antimykotischen Wirkstoff auskommen.The present invention relates to compositions for the treatment of onychomycosis which manage without a classic antifungal agent.
Onychomykose (Nagelpilz) ist keine schwere, aber häufige Erkrankung. Erhebungen zu Folge tragen 5-12% der Europäer Dermatophyten in den Nägeln, die Häufigkeit steigt mit dem Alter.Onychomycosis (nail fungus) is not a serious but common condition. Surveys show that 5-12% of Europeans have dermatophytes in their nails, and the incidence increases with age.
Die klassische Behandlung besteht im einfachen Fall aus einer antimykotischen Creme oder einem antimykotischen Nagellack. Der Nagellack enthält dabei ein Antimykotikum, wie z.B. Bifonazol, Clotrimazol, Ciclopirox oder Amorolfin. Bei schweren Erkrankungen kann eine chirurgische Entfernung des Nagels nötig sein, ferner besteht häufig Bedarf an systemischer Gabe von oralen Antimykotika wie z.B. Griseofulvin, Itraconazol, Terbinafin oder Fluconazol, welche ihrerseits Risiken und Nebenwirkungen aufweisen. Beispiele von Terbinafin-haltigen Zusammensetzungen zur Behandlung von Onychomykosen sind in
Es besteht daher weiterer Bedarf an effizienten Behandlungsmöglichkeiten von Onychomykosen.There is therefore a further need for efficient treatment options for onychomycosis.
Es wurde gefunden, dass überraschenderweise die in der

Der Haftvermittler enthält 40 - 60 % Hydroxyethylenmethacrylat und 40 - 60 % Phosphatdimethacrylat sowie 0,1 - 1,0 % Polymerisationsstarter. Die Polymerisationsstarter werden unten näher beschrieben. Das Mischungsverhältnis kann im Rahmen der oben genannten Prozentangaben variieren. Vorteilhafterweise sind die beiden Methacrylate in ungefähr gleichem Verhältnis enthalten. Es versteht sich von selbst, dass alle Komponenten zusammen 100 % ergeben.The adhesion promoter contains 40-60% hydroxyethylene methacrylate and 40-60% phosphate dimethacrylate as well as 0.1-1.0% polymerization initiator. The polymerization initiators are described in more detail below. The mixing ratio can vary within the scope of the percentages given above. The two methacrylates are advantageously contained in approximately the same ratio. It goes without saying that all components add up to 100%.

Der oben genannte Zusammensetzungsbereich erlaubt eine unterschiedliche Einstellung der mechanischen Eigenschaften, in Form unterschiedlicher Härtegrade. In der Praxis hat es sich bewährt, zwei Zusammensetzungen zur Verfügung zu stellen, von denen eine vergleichsweise weich, die andere vergleichsweise hart ist.The above-mentioned composition range allows a different setting of the mechanical properties, in the form of different degrees of hardness. In practice it has proven useful to provide two compositions, one of which is comparatively soft and the other is comparatively hard.
Die weiche Zusammensetzung enthält beispielsweise
Die harte Zusammensetzung enthält beispielsweise
Die in den Zusammensetzungen enthaltenden Monomere Bisphenol-(A)-(di)-methacrylat und Urethan-dimethacrylat sind bevorzugt in etwa gleicher Menge enthalten. Mischungsverhältnisse, bei denen die beiden Hauptkomponenten im Massenverhältnis zwischen 1:5 und 5:1 enthalten sind generell geeignet. Besonders vorzugswürdig sind Mischungsverhältnisse, bei denen die beiden Hauptkomponenten im Massenverhältnis zwischen 1:2 und 2:1 enthalten sind.The monomers bisphenol (A) - (di) methacrylate and urethane dimethacrylate contained in the compositions are preferably contained in approximately the same amount. Mixing ratios in which the two main components are contained in a mass ratio between 1: 5 and 5: 1 are generally suitable. Mixing ratios in which the two main components are present in a mass ratio between 1: 2 and 2: 1 are particularly preferred.
Das Material für die lichthärtende Nagelspange enthält ferner Füllstoffe und Pigmente. Hierbei handelt es sich um Füllstoffe auf Silikatbasis (Silicafiller), auf der Basis von gemahlenem Bariumglas (Bariumglasfiller) sowie Polymerpartikel. Die partikulären Zusätze haben Durchmesser im Bereich von 0,1-10 µm, vorzugsweise sind sie kleiner als 5 µm. Insbesondere die Füllstoffe auf der Basis von Bariumglas tragen erheblich zu den mechanischen Eigenschaften der Nagelspange bei. Zusätzlich können noch Pigmente in der Zusammensetzung enthalt sein, um der gebildeten Nagelspange ein ästhetisches Äußeres zu geben. Auch die Pigmente sollten vorzugsweise Durchmesser im Bereich von 0,1-10 µm aufweisen.The material for the light-curing nail braces also contains fillers and pigments. These are fillers based on silicate (silica filler), based on ground barium glass (barium glass filler) and polymer particles. The particulate additives have a diameter in the range from 0.1-10 μm, preferably they are smaller than 5 μm. In particular, the fillers based on barium glass contribute significantly to the mechanical properties of the nail braces. The composition can also contain pigments in order to give the nail brace formed an aesthetic appearance. The pigments, too, should preferably have a diameter in the range from 0.1-10 μm.
Das Material der lichthärtenden Nagelspange scheint zwar zum Therapieerfolg bei der Onychomykose beizutragen, jedoch nicht unabdingbar zu sein. Eine Therapie der Onychomykose durch Auftrag des Material der lichthärtenden Nagelspange allein scheint möglich zu sein, während eine Therapie der Onychomykose durch Auftrag des lichthärtenden Primers allein bevorzugt ist. Eine Auftragung beider Komponenten (Primer und Material der lichthärtenden Spange) ist besonders bevorzugt.The material of the light-curing nail braces seems to contribute to the success of therapy in onychomycosis, but it is not indispensable. Therapy of onychomycosis by applying the material of the light-curing nail brace alone seems to be possible, while therapy of onychomycosis by applying the light-curing primer alone is preferred. An application of both components (primer and material of the light-curing brace) is particularly preferred.
Die erfindungsgemäßen Zusammensetzungen enthalten ferner Polymerisationsstarter, die durch Bestrahlung mit Licht die gewünschte Polymerisationsreaktion auslösen können. Hierzu sind im Prinzip alle klassischen Polymerisationsstarter geeignet. Als besonders geeignet hat sich die Kombination Campherchinon mit Aminostartern, nämlich tertiären Aminen (z. B. Triethanolamin, N,N-Dimethyl-p-toluidin, Triethylamin, 4-Dimethylaminobezoesäureethylester, N,N-Tetramethylanilin) herausgestellt. Alternativ kann beispielsweise 2-Ethyl-Anthrachinon in Kombination mit N-Phenyl Glycin verwendet werden.The compositions according to the invention also contain polymerization initiators which can trigger the desired polymerization reaction by exposure to light. In principle, all classic polymerization initiators are suitable for this. The combination of camphorquinone with amino starters, namely tertiary amines (e.g. triethanolamine, N, N-dimethyl-p-toluidine, triethylamine, ethyl 4-dimethylaminobenzoate, N, N-tetramethylaniline) has proven to be particularly suitable. Alternatively, for example, 2-ethyl-anthraquinone can be used in combination with N-phenyl glycine.

Bei Verwendung eines derartigen Systems kann die fertige Zusammensetzung überraschenderweise über längere Zeit gelagert werden, ohne dass eine Polymerisationsreaktion eintritt. Erst nach Beleuchtung mit einer angepassten Lichtquelle tritt die Polymerisationsreaktion ein. Hierzu kann z.B. eine LED-Lichtquelle mit einer Wellenlänge von ca. 425 nm und einer Lichtleistung von 1000-1500mW/cm2 verwendet werden.When using such a system, the finished composition can surprisingly be stored for a long time without a polymerization reaction occurring. The polymerization reaction only occurs after lighting with an adapted light source. For this purpose, for example, an LED light source with a wavelength of approx. 425 nm and a light output of 1000-1500mW / cm 2 can be used.
Die Erfindung kann im Rahmen einer Nagelkorrekturbehandlung, wie in der
Das erfindungsgemäße Kit kann aber auch ohne Nagelkorrekturbehandlung verwendet werden. Hierzu wird zunächst der Primer auf den betroffenen Nagel flächig aufgetragen. Dabei ist insbesondere darauf zu achten, dass der Nagel trocken ist. Der betroffene Nagel sollte insbesondere in den 24 Stunden vor der Auftragung nicht länger mit Wasser in Kontakt gewesen sein. Der Patient sollte beispielsweise nicht gebadet haben. Ein kurzes Waschen oder Duschen ist hingegen unschädlich, sofern der Nagel wieder gut getrocknet wurde. Erforderlichenfalls kann der Nagel mit einem Heißluftgebläse getrocknet werden. Nach dem Auftragen wird mittels einer Lichtquelle (bevorzugt blaues Licht mit ca. 425 nm und mindestens 1000mW/cm2) die Polymerisation gestartet. Bei Verwendung einer üblichen Lichtquelle ist die Polymerisation nach einem Zeitraum von 5 Sekunden bis 60 Sekunden abgeschlossen, im Regelfall ist eine 10-sekündige Belichtung ausreichend. Anschließend wird die lichthärtende Nagelspange aufgetragen. Für den Fall einer reinen antimykotischen Behandlung kann die Auftragung flächig erfolgen. However, the kit according to the invention can also be used without nail correction treatment. To do this, the primer is first applied over the entire surface of the affected nail. It is particularly important to ensure that the nail is dry. The affected nail should not have been in contact with water any longer, especially in the 24 hours prior to application. For example, the patient should not have bathed. A short wash or shower, on the other hand, is harmless provided the nail has been dried well again. If necessary, the nail can be dried with a heat gun. After application, the polymerization is started by means of a light source (preferably blue light with approx. 425 nm and at least 1000 mW / cm 2). If a conventional light source is used, the polymerization is complete after a period of 5 seconds to 60 seconds; as a rule, a 10-second exposure is sufficient. Then the light-curing nail brace is applied. In the case of a purely antimycotic treatment, the application can be made over a large area.
Soll gleichzeitig eine mechanische Korrektur vorgenommen werden, erfolgt die Auftragung wie in der
Wie oben bereits beschrieben, ist in vielen Fällen die Anwendung des Primers für die Therapie der Onychomykose ausreichend.As already described above, in many cases the use of the primer is sufficient for the therapy of onychomycosis.
Die erfindungsgemäßen Zusammensetzungen werden vorzugsweise in entsprechend angepassten Behältern angeboten. Für den Primer eignen sich grundsätzlich Fläschchen aus Glas oder Kunststoff mit einem Applikationspinsel oder einer Applikationsbürste. Die Zusammensetzungen zur Herstellung von lichthärtenden Nagelspangen sind typischerweise stärker viskos und werden vorzugsweise in Kartuschen zur Nutzung zusammen mit einer Kartuschenpresse oder -pistole angeboten. Alle Behältnisse sind vorzugsweise lichtundurchlässig.The compositions according to the invention are preferably offered in appropriately adapted containers. Basically, bottles made of glass or plastic with an application brush or an application brush are suitable for the primer. The compositions for making light curing nail braces are typically more viscous and are preferably presented in cartridges for use with a cartridge gun or gun. All containers are preferably opaque.
Mit den erfindungsgemäßen Zusammensetzungen wird das notwendige Material zur Verfügung gestellt, um Onychomykosen effektiv zu behandeln, ohne klassische Antimykotika lokal oder systemisch einsetzen zu müssen. Überraschenderweise wurde gefunden, dass die beschriebenen Zusammensetzungen auch dazu geeignet sind, bakterielle Infektionen der Nägel (z.B. durch Staphylocccus aureaus, Streptokokken oder Pseudomonas aeruginosa) effektiv zu bekämpfen. Die Auftragung der Zusammensetzungen auf den betroffenen Nagel erfolgt, wie oben für die Onychomykose beschrieben.The compositions according to the invention provide the necessary material to effectively treat onychomycoses without having to use classic antimycotics locally or systemically. Surprisingly, it has been found that the compositions described are also suitable for effectively combating bacterial infections of the nails (e.g. by Staphylocccus aureaus, streptococci or Pseudomonas aeruginosa). The compositions are applied to the affected nail as described above for onychomycosis.
