Antimykotisches Mittel mit hoher Wirkstoff-Freisetzung in Form von CremeAntifungal agent with high active ingredient release in the form of cream

5 die eine höhere Freisetzung des Wirkstoffes aufweist und dadurch eine Kurzzeittherapie ermöglicht.5 which has a higher release of the active ingredient and thus enables short-term therapy.
Für die Behandlung von Mykosen beim Menschen, vor allem * die Mykosen der Haut und der Hautanhangsgebilde, sind be reits Zubereitungen von antimykotischen Derivaten be-' 10 kannt geworden. Mit diesen Zubereitungen wurden für eine vollständige Sanierung 14 bis 21 Tage Therapiezeit benötigt.Preparations of antifungal derivatives have already been known for the treatment of mycoses in humans, especially * the mycoses of the skin and the appendages of the skin. With these preparations, 14 to 21 days of therapy were required for complete refurbishment.
Um z.B. bei Vaginal- oder Buccal-Mykosen oder Dermatomykosen zu einer Verkürzung der Therapiedauer zu kommen,To e.g. to reduce the duration of therapy for vaginal or buccal mycoses or dermatomycoses,
Le A 22 266-Ausland t - 2 - t - - benötigt man, besonders zur Eliminierung der Keime, bzw. um eine mykologisch gesicherte Sanierung zu erzielen, eine höhere Freisetzung der Wirkstoffe im wäßrigen Milieu. Dafür sind die bekannten Formulierungen 5 nur begrenzt geeignet, weil sich von dem vorhandenen Wirkstoffangebot nur ein kleiner Anteil im Flüssigkeitsvolumen am Ort der Infektion löst. Wenn man nun durch oder ohne weitere Erhöhung der Wirkstoffkonzentration eine Verkürzung der Therapiedauer, z.B. auf einige Tage 10 bei täglicher einmaliger Applikation, erreichen will, muß man für eine optimale Bioverfügbarkeit des Wirkstoffes Sorge tragen.Le A 22 266 abroad t - 2 - t - - one needs, especially to eliminate the germs or to achieve a mycologically safe remediation, a higher release of the active substances in the aqueous environment. The known formulations 5 are only suitable for this to a limited extent, because only a small proportion of the liquid volume at the site of the infection dissolves from the available active substance. If one now shortens the duration of therapy by or without further increasing the active substance concentration, e.g. to reach 10 for a few days with a single daily application, care must be taken to ensure optimal bioavailability of the active ingredient.
Es wurde nun'gefunden, daß solche Formulierungen des Bifonazols, die neben üblichen Formulierungsstoffen 1 5 und Lösungsmitteln 5 - 25 % Spreitmittel enthalten, den Wirkstoff in höherem Maße freisetzen und dadurch eine Verkürzung der Therapiedauer auf einige Tage ermöglichen. Dieser Effekt der höheren Wirkstoff-Frei-setzung kann bis zu einer Zehnerpotenz erreichen.It has now been found that such formulations of bifonazole, which in addition to conventional formulations 15 and solvents contain 5-25% spreading agent, release the active ingredient to a greater extent and thereby enable the duration of therapy to be shortened to a few days. This effect of the higher release of active ingredient can reach up to a power of ten.

Verfahrensvariante (a) 13,6 g (0,2 Mol) Imidazol werden in 150 ml Acetonitril ge-5 löst und bei 10°C mit 3,5 ml Thionylchlorid versetzt. Zu der so erhaltenen Lösung von Thionyl-bis-imidazol gibt man 13 g (0,05 Mol) Diphenyl-phenyl-carbinol. Nach 15-stündigem Stehen bei Raumtemperatur wird das Lösungsmittel durch Abdestillieren im Vakuum entfernt. Der Rückstand wird in 10 Chloroform aufgenommen und mit Wasser gewaschen. Die organische Phase wird abgetrennt, über Natriumsulfat getrocknet, filtriert und das Lösungsmittel im Vakuum abdestilliert. Der ölige Rückstand wird in Essigester gelöst und durch Filtration von unlöslichen, harzigen Be-15 standteilen befreit. Das Lösungsmittel wird erneut im Vakuum abdestilliert und der Rückstand durch Umkristallisation aus Acetonitril gereinigt. Man erhält 8,7 g (56 % der Theorie) Diphenyl-imidazolyl-(1 )-phenyl-methan (Bifonazol) vom Schmelzpunkt 142°C.Process variant (a) 13.6 g (0.2 mol) of imidazole are dissolved in 150 ml of acetonitrile and 3.5 ml of thionyl chloride are added at 10 ° C. 13 g (0.05 mol) of diphenyl-phenyl-carbinol are added to the solution of thionyl-bis-imidazole thus obtained. After standing at room temperature for 15 hours, the solvent is removed by distillation in vacuo. The residue is taken up in 10 chloroform and washed with water. The organic phase is separated off, dried over sodium sulfate, filtered and the solvent is distilled off in vacuo. The oily residue is dissolved in ethyl acetate and the insoluble, resinous constituents are removed by filtration. The solvent is distilled off again in vacuo and the residue is purified by recrystallization from acetonitrile. 8.7 g (56% of theory) of diphenyl-imidazolyl- (1) -phenyl-methane (bifonazole) of melting point 142 ° C. are obtained.

Wirksamkeitstestung der erfindungsgemäßen Mittel am Trichophyton-infizierten Meerschweinchen.Effectiveness test of the agents according to the invention on Trichophyton-infected guinea pigs.
Als Testmodell zur vergleichenden Wirksamkeitsprüfung der erfindungsgemäßen Formulierungen verwendeten wir 5 Trichophyton-infizierte Pirbright-white-Meerschwein- chen mit einem durchschnittlichen Gewicht von 600 g. Die Tiere wurden auf dem Rücken mit einer elektrischen Haarschneidemaschine so geschoren, daß ca. 1/10 mm lange Haarstümpfe stehen blieben.We used 5 trichophyton-infected Pirbright white guinea pigs with an average weight of 600 g as a test model for comparative effectiveness testing of the formulations according to the invention. The animals were shaved on their backs with an electric hair clipper so that hair stumps about 1/10 mm long remained.
1° Die Infektion mit Trichophyton mentagrophytes erfolgte durch leichtes Verreiben einer 24 Stunden in Sabouraud-Nährlösung angekeimten Sporensuspension des Erregers auf einer ca. 2 x 2 cm großen Fläche des geschorenen Rückens der Tiere. Aufgetragen wurden pro Tier 0,5 ml 4 C 5 13 Keimsuspension, die 1 - 3 x 10 infektiöse Pilzpartikel enthielten.1 ° Trichophyton mentagrophytes was infected by gently rubbing in a spore suspension of the pathogen germinated in Sabouraud nutrient solution for 24 hours on an approx. 2 x 2 cm area of the sheared back of the animals. 0.5 ml of 4 C 5 13 germ suspension, which contained 1-3 x 10 infectious fungal particles, was applied to each animal.
Bei diesem Infektionsmodus zeigen sich 2-3 Tage post infectionem die ersten Symptome der Dermatopnytose als Rötung und Schuppung der Haut. Bei unbehandelten Tieren 2^ ist ca. 14 Tage p.i. die Dermatophytose maximal ausgeprägt: Flächiger Haarausfall und blutige Integument-Defekte innerhalb einer entzündlich veränderten, schuppigen Randzone.With this mode of infection, the first symptoms of dermatopnytosis appear as reddening and scaling of the skin 2-3 days after infection. In untreated animals 2 ^ is approx. 14 days p.i. the dermatophytosis is maximal: extensive hair loss and bloody integument defects within an inflammatory, scaly peripheral area.
Die zu prüfenden Formulierungen wurden 1-mal, am 2. Tag 25 post infectionem, lokal auf die gerötete Infektionsstelle der Tiere appliziert und mit einem Hornspatel leichtThe formulations to be tested were applied once, on the second day 25 post infection, locally to the reddened infection site of the animals and lightly with a horn spatula

^ In diesem Test zeigen die erfindungsgemäßen Formulierungen eine sehr gute Wirkung.^ In this test, the formulations according to the invention show a very good effect.
Verwendet man zum Vergleich Formulierungen, die neben Bifonazol kein Spreitmittel enthalten, so wird ein Effekt, der dem der erfindungsgemäßen Formulierungen 10 entspricht, erst nach dreimaliger Applikation erreicht.If, for comparison, formulations are used which contain no spreading agent in addition to bifonazole, an effect which corresponds to that of the formulations 10 according to the invention is only achieved after three applications.
