Abstract
Description
Die androgenetische Alopezie ist die häufigste Form des Haarverlustes, der sowohl bei Männern als auch bei Frauen auftreten kann. Unter dem Begriff "androgenetische Alopezie" werden Haarmangelzustände verstanden, deren Ursache eine genetisch determinierte Überempfindlichkeit der Haarwurzel auf 5α- Dihydrotestosteron ist.Androgenetic alopecia is the most common form of hair loss, both can occur in both men and women. Under the term "Androgenetic alopecia" is understood to mean hair deficiency conditions, the Cause a genetically determined hypersensitivity of the hair root to 5α- Is dihydrotestosterone.
Ein typisches Beispiel einer androgenetischen Alopezie ist die gewöhnliche Glatze des Mannes. Eine androgenetische Alopezie kann jedoch auch bei Frauen im ge schlechtsreifen Alter - mit oder ohne die klinischen Merkmale der männlichen Glatze - auftreten.A typical example of androgenetic alopecia is baldness of the man. Androgenetic alopecia can also occur in women in ge poorly mature age - with or without the clinical features of male baldness - occur.
Die Behandlung des androgenetischen Haarausfalls setzt die frühzeitige Unterbre chung der pathogenetischen Vorgänge voraus, die zur Rückbildung des Haarfollikels führen. Um eine Normalisierung des Haarzyklus, d. h. eine Verlängerung der Wachs tumsphase der Haare zu erreichen, ist eine Verminderung der biologisch aktiven Androgenmenge am Follikel erforderlich. Wenn Endokrinopathien ausgeschlossen und Medikamente, die Testosteron oder andere androgen wirksame Substanzen enthalten, abgesetzt sind, ist die Hemmung der Androgenstimulation am Zielorgan notwendig. Zur Erreichung dieser Zielsetzung sind theoretisch zwei Wege denkbar: Erstens, die Aktivitätshemmung der 5α-Reduktase und damit Minderung der Umwandlung von Testosteron in 5α-Dihydrotestosteron, z. B. durch Östrogen, und zweitens eine Blockierung des Dihydrotestosteron-empfindlichen Rezeptorproteins, z. B. durch Antiandrogene.The treatment of androgenetic hair loss sets the early stage The pathogenetic processes leading to the regression of the hair follicle to lead. To normalize the hair cycle, i.e. H. an extension of the wax Reaching the hair's growth phase is a reduction in the biologically active Amount of androgen required on the follicle. If endocrinopathies are excluded and drugs that contain testosterone or other androgenic substances contained, are discontinued, the inhibition of androgen stimulation on the target organ necessary. There are theoretically two ways to achieve this goal: First, the inhibition of activity of 5α-reductase and thus reduction of Conversion of testosterone to 5α-dihydrotestosterone, e.g. B. by estrogen, and secondly, a blocking of the dihydrotestosterone-sensitive receptor protein, e.g. B. by antiandrogens.
Da alle systemischen Therapiemaßnahmen bei der androgenetischen Alopezie sich gegen die Androgenwirkung richten, ist ihre Anwendung bei gebährfähigen Frauen nur bei gleichzeitiger Kontrazeption möglich. Nach der Einführung der oralen Antikonzeptiva hat es sich gezeigt, daß je nachdem, ob man ein östrogenbetontes oder ein Präparat mit androgener Restwirkung verabreicht, der Verlauf einer androgenetischen Alopezie und ihrer Begleitsymptome günstig oder ungünstig beeinflußt wird.Since all systemic therapeutic measures in androgenetic alopecia themselves directed against the androgen effect is its use in fertile women only possible with simultaneous contraception. After the introduction of the oral Anticonceptives have shown that depending on whether you are an estrogen-stressed or administered a preparation with residual androgenic activity, the course of a androgenetic alopecia and its accompanying symptoms cheap or unfavorable being affected.
In Ermangelung einer anderen, stärker wirksamen, gefahrlosen Alternative werden zur Behandlung der androgenetischen Alopezie bei Männern bislang östrogenhaltige Haarwässer verordnet. Bei Frauen wird diese Lokaltherapie als unterstützende Maß nahme empfohlen und das Hauptgewicht auf die systemische Behandlung gelegt.In the absence of another, more effective, safe alternative for the treatment of androgenetic alopecia in men previously estrogen-containing Hair lotions prescribed. In women, this local therapy is used as a supportive measure recommended and the emphasis was placed on systemic treatment.
Alle Patienten werden angewiesen, den noch behaarten Bereich der Kopfhaut zu behandeln und nicht die bereits kahlen Bezirke. In vielen Fällen gelingt es mit Hilfe dieser Lokalmaßnahmen die Schübe des Haarausfalls zu mildern oder zum Stillstand zu bringen.All patients are instructed to close the still hairy area of the scalp treat and not the already bare districts. In many cases it can be done with help of these local measures to mitigate the flare-ups of hair loss or to Bring to a standstill.
Topisch wirksame Antiandrogene sind aus der französischen Patentschrift 2 693 461 und aus US 5,411,981 ((4-[3-(4-Hydroxybutyl)-4,4-dimethyl-2,5-dioxo-1-imidazoli dinyl]2-(tifluormethyl)-benzonitrile) sowie aus der PCT Anmeldung WO 98/05654 (3- Aryl-2,4-dioxo-oxazolidine) bekannt, stehen aber derzeitig noch nicht zu Therapie zwecken zur allgemeinen Verfügung.Topical antiandrogens are from French patent 2,693,461 and from U.S. 5,411,981 ((4- [3- (4-hydroxybutyl) -4,4-dimethyl-2,5-dioxo-1-imidazoli dinyl] 2- (tifluoromethyl) benzonitrile) and from PCT application WO 98/05654 (3- Aryl-2,4-dioxo-oxazolidine) are known, but are not yet available for therapy for general use.
Beide Substanzklassen zeigen nach topischer Applikation eine hohe Bindungsaffini tät zum Androgenrezeptor an der Haarwurzel bei nahezu fehlender systemischer Aktivität.Both substance classes show a high binding affinity after topical application to the androgen receptor at the hair root with almost no systemic Activity.
Aufgrund der Substanz-inhärenten Teratogenität von Antiandrogenen mit Einfluß auf die Geschlechtsdifferenzierung im Spätstadium der Schwangerschaft sind die ge nannten Substanzen in Form von herkömmlichen wäßrig/alkoholischen Haarwäs sern wegen des Auftretens von Substanzausfällungen an der Applikationsstelle nach Verdunsten des Lösungsmittels und dem damit verbundenen toxikologischen Risikos der Substanzübertragung auf Schwangere nicht verwendbar. Ferner ist durch her kömmliche Zubereitungen zum Auftragen auf die Kopfhaut die verzögerte Wirkstoff freisetzung über einen längeren Zeitraum zur Vermeidung von hohen systemischen Wirkstoffkonzentrationen und dem damit einhergehenden Auftreten von systemi schen antiandrogen Effekten nicht gewährleistet.Influenced by the substance-inherent teratogenicity of antiandrogens gender differentiation in the late stages of pregnancy are the most common named substances in the form of conventional aqueous / alcoholic hair washes follow up on the occurrence of substance precipitation at the application site Evaporation of the solvent and the associated toxicological risk the substance transfer to pregnant women cannot be used. Furthermore is by forth Conventional preparations for application to the scalp are the delayed active ingredient Release over a longer period to avoid high systemic Active substance concentrations and the associated occurrence of systemi anti-androgenic effects are not guaranteed.
Um die in oben genannten Patenten antiandrogen Wirkstoffe für eine sichere und wirksame Therapie zur Verfügung stellen zu können, war es daher erforderlich, Formulierungen zu finden, die die beschriebenen Nachteile von herkömmlichen Kopfhautbehandlungsmitteln nicht aufweisen.In order to use the antiandrogenic active ingredients for safe and To be able to provide effective therapy, it was therefore necessary Find formulations that describe the disadvantages of conventional ones Do not have scalp treatment agents.

Ganz besonders bevorzugt sind Verbindungen der Formel I genannt wie 4-[3-(4- Hydroxybutyl)-4,4-dimethyl-2,5-dioxo-1-imidazolidinyl]-2-(trifluormethyl)-benzonitril oder 4-(5-methyl-2,4-dioxo-5-trifluormethyl)-oxazolidin-3-yl)-2-(trifluormethyl)- benzonitril.Compounds of the formula I such as 4- [3- (4- Hydroxybutyl) -4,4-dimethyl-2,5-dioxo-1-imidazolidinyl] -2- (trifluoromethyl) benzonitrile or 4- (5-methyl-2,4-dioxo-5-trifluoromethyl) oxazolidin-3-yl) -2- (trifluoromethyl) - benzonitrile.
Unter dem Begriff "Halogen" wird Fluor, Chlor, Brom oder Jod verstanden. Unter dem Begriff "Alkyl" oder "Alkenyl" werden Kohlenwasserstoffreste verstanden deren Kohlenstoffkette geradkettig oder verzweigt sind. Ferner können die Alkenylreste auch mehrere Doppelbindungen enthalten. Unter dem Begriff "physiologisch verträgliches Lösemittel" werden beispielsweise Wasser, (C1-C6)-Alkohole wie Methanol, Ethanol, Propanol, Isopropanol, Butanol, Pentanol oder Hexanol verstanden. Es können aber auch Mischungen der Lösemittel eingesetzt werden.The term "halogen" means fluorine, chlorine, bromine or iodine. The term "alkyl" or "alkenyl" is understood to mean hydrocarbon radicals whose carbon chain is straight-chain or branched. The alkenyl radicals can also contain a plurality of double bonds. The term "physiologically compatible solvent" means, for example, water, (C 1 -C 6 ) alcohols such as methanol, ethanol, propanol, isopropanol, butanol, pentanol or hexanol. However, mixtures of the solvents can also be used.
Weichmacher sind Stoffe, die spröden Massen, z. B. filmbildenden Substanzen, Geschmeidigkeit und Flexibilität verleihen. Durch Art und Menge des zugesetzten Weichmachers kann darüber hinaus auch das Freisetzungsprofil von Substanzen aus Filmen gesteuert werden. Als Weichmacher kommen verschiedene Substanzklassen in Betracht, insbesondere ethoxylierte Verbindungen, Panthenol und Ester der Adipin- oder Sebacinsäure. Plasticizers are substances that contain brittle materials, e.g. B. film-forming substances, Give suppleness and flexibility. By type and amount of added Plasticizers can also change the release profile of substances be controlled from films. Various come as plasticizers Substance classes into consideration, especially ethoxylated compounds, panthenol and esters of adipic or sebacic acid.
Filmbildner sind Stoffe unterschiedlicher Zusammensetzung, die dadurch charakterisiert sind, daß sie in Wasser oder anderen geeigneten Lösemitteln gelöst nach dem Verdunsten des Wassers oder des Lösemittels Filme auf der Haut bilden, die unter anderem dazu geeignet sind, inkorporierte Wirkstoffe über einen bestimmten Zeitraum gezielt freizusetzen.Film formers are substances of different compositions that result are characterized in that they are dissolved in water or other suitable solvents form films on the skin after the water or solvent has evaporated, which are suitable, among other things, for incorporated active substances via a release specific time period.
Im Gegensatz zu Verdickungsmitteln, welche flüssigen Zubereitungen zugesetzt werden, um eine bestimmte Viskosität einzustellen, beeinflussen Filmbildner die Viskosität einer Flüssigkeit nur in geringen Maße. Nachteil von Verdickungsmitteln ist die schlechte Verteilbarkeit der Applikationsform.In contrast to thickeners, which added liquid preparations to set a certain viscosity, film formers influence the Viscosity of a liquid only to a small extent. Disadvantage of thickeners is the poor spreadability of the application form.
Die erfindungsgemäßen Zubereitungen zeichnen sich in erster Linie durch eine gleichmäßige über einen bestimmten Zeitraum ablaufende Freigabe der Verbindung der Formel I aus dem - sich nach dem Auftragen der Zubereitung bildenden - elastischen, auf der Haut gut haftenden, Film aus. Dadurch wird sichergestellt, daß therapeutisch wirksame Antiandrogen-Konzentrationen an dem Zielorgan - der Haarwurzel - über einen längeren Zeitraum erreicht werden, ohne daß kurzfristig hohe Blutspiegelkonzentrationen auftreten, die naturgemäß zu einer systemischen Belastung des Patienten führen.The preparations according to the invention are primarily characterized by a even release of the connection over a certain period of time of the formula I from the - formed after application of the preparation - elastic film that adheres well to the skin. This ensures that therapeutically effective antiandrogen concentrations on the target organ - the Hair roots - can be achieved over a longer period of time without short term high blood levels occur which naturally lead to a systemic Lead to patient stress.
Vorzugsweise handelt es sich bei den pharmazeutischen Zubereitungen um flüssige Zubereitungen wie Haarwässer oder Haartonika, die als Hauptbestandteile Wasser, aber auch wäßrigen (C1-C6)-Alkohol, wie beispielsweise Ethanol, Propanol oder Isopropanol enthalten können, ferner um Lotionen oder um halbfeste Zubereitungen wie Emulsionen, Cremes, Gele oder Salben. Gegebenenfalls können die Zubereitungen auch in Aerosolform vorliegen.The pharmaceutical preparations are preferably liquid preparations, such as hair lotions or hair tonics, which may contain water as the main constituents, but also aqueous (C 1 -C 6 ) alcohol, such as, for example, ethanol, propanol or isopropanol, furthermore lotions or semisolid Preparations such as emulsions, creams, gels or ointments.
