Description
Die vorliegende Erfindung betrifft neue galenische Dar
reichungsformen und Kompositionen mit verbessertem Resorptionsvermögen für das Antibiotikum S 7481 /F- 1 der Formel
EMI2.1
Erfindungsgemäss enthalten die neuen galenischen Kom positionen die Verbindung der Formel I zusammen mit a) Sesamöl und/oder b) nichtionogenen Tensiden und/oder c) umgeesterten nichtionogenen Triglyzeriden und/oder d) einem Gemisch bestehend aus einem oder mehreren Lecithinen, umgeesterten nichtionogenen Triglyzeriden oder Äthyloleat und/oder e) einem Neutralöl.
Diese Kompositionen werden in folgenden galenischen Formen verabreicht: Trinklösung, Trinkemulsion und parenterale Injektionslösungen.
Erfindungsgemäss gelangt man zu den neuen galenischen Kompositionen, indem man das Antibiotikum S 7481/F-1 mit einem oder mehreren der unter a)e) angeführten Agenzien vermischt.
Das erfindungsgemäss verwendete unter a) angeführte Sesamöl wird mit dem Antibiotikum S 7481/F-1 bei einer Temperatur von 18 bis 50 "C, vorzugsweise bei Raumtemperatur, gemischt, wobei für 1 g Antibiotikum zweckmässigerweise 10 bis 100 ml Sesamöl verwendet werden. Das Auflösen erfolgt auf an sich bekannte Weise mit Hilfe eines Propeller- oder Magnetrührers. Die so erhaltene Komposition wird in Flaschen oder Ampullen abgefüllt und kann sowohl oral als auch parenteral angewendet werden.
Die erfindungsgemäss verwendeten unter b) angeführten nicht ionogenen Tenside umfassen insbesondere Polyoxy äthylensorbitolmonooleat (Tween 80), Glyzerinpolyäthylenglykolricinoleat (Cremophor EL), polyäthoxyliertes hydriertes Ricinusöl (Cremophor 40 und 60) und Lecithine. Es können ebenfalls Gemische dieser Tenside verwendet werden.
Die Herstellung der Komposition erfolgt durch Auflösen des Antibiotikums S 7481/F-1 in einem Gemisch des Tensids mit Äthanol gegebenenfalls in Gegenwart von Hilfsstoffen, beispielsweise Athyloleat, bei Temperaturen von + 16 bis 40 "C, vorzugsweise bei Raumtemperatur, wobei pro I g des Antibiotikums bis 5 g des Tensids verwendet werden. Der
Lösung können ebenfalls andere Zusätze, wie Neutralöle, z. B. Triglyceride auf Basis gesättigter Pflanzenfettsäuren der Kettenlänge C8-C12 (Miglyol 812) enthalten.
Die erhaltenen Lösungen werden in Flaschen oder Ampullen abgefüllt und können oral oder parenteral verabreicht werden.
Die unter c) angeführten umgeesterten nicht-ionogenen Triglyzeride können beispielsweise aus umgeestertem pharmazeutischem Kernöl und/oder umgeestertem pharmazeutischem Mandelöl und/oder umgeestertem pharmazeutischem Erdnussöl und/oder umgeestertem pharmazeutischem Olivenöl und/oder umgeestertem pharmazeutischem Palmöl bestehen, deren Gemisch (polyoxyäthylierte Glyzeride) sich unter dem Namen LABRAFIL im Handel befindet (siehe Fiedler, Lexikon der Hilfsstoffe 1971, Seite 320). Die Herstellung der erfindungsgemässen galenischen Mischungen des Antibiotikums S 7481/F-1 erfolgt dadurch, dass man 10-50 mg des Antibiotikums in 0,5 ml Labrafil vorzugsweise in 0,2 ml der umgeesterten nichtionogenen Triglyzeride bei Temperaturen von 16-40 "C, insbesondere bei Raumtemperatur, löst.
Die so erhaltene Lösung wird anschliessend für orale oder parenterale Verabreichung in Flaschen oder Ampullen abgefüllt.
Das unter d) aufgeführte Gemisch enthält die unter c) besprochenen umgeesterten nichtionogenen Triglyzeride oder Athyloleat, Lecithine, wie z. B. isolierte Sojaphospholipide in Sojaöl (z. B. Epikuron 125) und Wasser, und wird konserviert mit einem Konservierungsmittel (z. B. mit Nipakobin, einem Gemisch von 65% p-Hydroxy-benzoesäuremethylester und 35% p-Hydroxybenzoesäure-propylester in einem Verhältnis von 0,05 bis 0,09%, vorzugsweise 0,08%).
Die zur oralen Verabreichung geeignete Komposition wird erhalten, indem man das Antibiotikum (1 mg) in dem Gemisch von einem oder mehreren Lecithinen und umgeesterten nichtionogenen Triglyzeriden oder Äthyloleat, dem noch ein inertes Lösungsmittel, beispielsweise ein pharmazeutisch annehmbarer niederer Alkohol, wie z. B. Ätha- nol, in einem Verhältnis von 1 zu 10 bezogen auf das o.e.
Gemisch zugesetzt wurde, bei Temperaturen von 18 bis 30 "C, vorzugsweise bei Raumtemperatur, löst, dann mit den übrigen Zusätzen, z. B. Konservierungsmittel, versetzt und die Lösung mit einem Homogenisator mit Wasser mischt und homogenisiert. Die erhaltene Emulsion wird zur oralen Verabreichung in Flaschen abgefüllt.
Das unter e) angegeben Neutralöl, beispielsweise Triglyzerid auf Basis gesättigter Pflanzenfettsäuren der Kettenlänge C8 bis C12 (Miglyol 812), wird mit dem Antibiotikum S 7481/F-1 bei Temperaturen von 16 bis 40 C, vorzugsweise bei Raumtemperatur, vermischt, wobei für 1 g Antibiotikum von 5 bis 50 ml, vorzugsweise 10 ml, Neutralöl verwendet werden. Bei der Herstellung des Gemisches ist die Anwesenheit eines Lösungsmittels, z. B. Benzoesäurebenzylester (siehe Fiedler, Lexikon der Hilfsstoffe 1971, Seite 79), 1,2 Butylenglykol-l-methyläther (Soluphor CE 5151) oder Äthanol in einem Anteil von 2 bis 15% zweckmässig. Die erhaltene Komposition wird zur parenteralen Verabreichung in Ampullen abgefüllt.
Die erfindungsgemässen Kompositionen, die überdies noch übliche Zusätze, wie z. B. Konservierungsmittel, enthalten können, zeichnen sich dadurch aus, dass sie eine gute Resorption des üblicherweise schwer resorbierbaren Antibiotikums S 7481/F-1 ermöglichen.
Die erfindungsgemässen Kompositionen können in den nachfolgenden galenischen Formen verabreicht werden:
A) Trinklösungen
B) Trinkemulsionen oder
C) Parenterale Injektionslösungen.
Als Trinklösungen werden bevorzugt folgende Kompositionen verabreicht:
1) Antibiotikum S 7481/F-1 und Sesamöl, gegebenenfalls zusammen mit den unter bd) beschriebenen Zusätzen,
2) Antibiotikum S 7481/F-1 und Äthyloleat und ein unter b) angegebenes Tensid.
Diese Trinklösungen enthalten gegebenenfalls ebenfalls Äthanol in einem Anteil von 1% bis 15%.
Als Trinkemulsion verwendet man insbesondere eine Komposition bestehend aus dem Antibiotikum S 7481/F-1, einem umgeesterten nichtionogenen Triglyzerid, insbesondere Labrafil, und einem Lecithin, insbesondere isolierte Sojaphospholipide in Sojaöl. Diese Komposition enthält überdies noch von 2 bis 10% Äthanol und von 50 bis 80% Wasser.
Als parenterale Injektionslösungen werden bevorzugt folgende Kompositionen verabreicht:
3) Antibiotikum S 7481/F-1 und Sesamöl gegebenenfalls zusammen mit den unter b}d) beschriebenen Zusätzen,
4) Antibiotikum S 7481/F-1 und ein Neutralöl zusammen mit Äthanol und gegebenenfalls den unter b)-d) beschriebenen Zusätzen,
5) Antibiotikum S 7481/F-1 und Äthyloleat zusammen mit Äthanol und gegebenenfalls den unter b)d) beschriebenen Zusätzen.
Zur Bestimmung der Resorption wird folgende Methode verwendet:
Probanden oder Tieren wird das Antibiotikum S 7481/F
1 in verschiedenen galenischen Formen oral verabreicht. Vor der Einnahme und zu verschiedenen Zeiten nachher wird Blut entnommen. Das Serum wird in verschiedenen Mengen (0,3 bis 10%) einer Mausmilzzellsuspension in vitro beigemischt. Die Lymphozytenproliferation wird mittels Concanavalin A induziert. Nach 72 Std. Kultur und nach einem 24 Std. 3H-Thymidin-puls werden die cpm/Kultur, d. h. der Thymidineinbau, gemessen. Letzterer wird als Parameter für die Lymphozytenvermehrung gewertet. Wenn im Serum das Antibiotikum S 7481/F-1 vorliegt, dann wird gegenüber den Kontrollen (Serum vor Substanzapplikation) eine konzentrationsabhängige Hemmung der Lymphozytenproliferation beobachtet.
In den nachfolgenden Beispielen, worin die Herstellung der erfindungsgemässen Kompositionen im einzelnen beschrieben werden, sind alle Temperaturen in Grad-Celsius angegeben. Als Raumtemperatur gilt eine Temperatur von 25"C.

According to the invention, the new pharmaceutical compositions are obtained by mixing the antibiotic S 7481 / F-1 with one or more of the agents listed under a) e).
The sesame oil listed under a) according to the invention is mixed with the antibiotic S 7481 / F-1 at a temperature of 18 to 50 ° C., preferably at room temperature, 10 to 100 ml of sesame oil being expediently used for 1 g of antibiotic The composition obtained in this way is filled into bottles or ampoules and can be used both orally and parenterally.
The nonionic surfactants mentioned under b) according to the invention include in particular polyoxyethylene sorbitol monooleate (Tween 80), glycerol polyethylene glycol ricinoleate (Cremophor EL), polyethoxylated hydrogenated castor oil (Cremophor 40 and 60) and lecithins. Mixtures of these surfactants can also be used.
The composition is produced by dissolving the antibiotic S 7481 / F-1 in a mixture of the surfactant with ethanol, if appropriate in the presence of auxiliaries, for example ethyl oleate, at temperatures from + 16 to 40 ° C., preferably at room temperature, with per 1 g of Antibiotic up to 5 g of the surfactant can be used
Other additives such as neutral oils, e.g. B. Triglycerides based on saturated vegetable fatty acids chain length C8-C12 (Miglyol 812).
The solutions obtained are filled into bottles or ampoules and can be administered orally or parenterally.
The transesterified nonionic triglycerides listed under c) can consist, for example, of transesterified pharmaceutical core oil and / or transesterified pharmaceutical almond oil and / or transesterified pharmaceutical peanut oil and / or transesterified pharmaceutical olive oil and / or transesterified pharmaceutical palm oil, the mixture of which (polyoxyethylated glycerides) can be the name LABRAFIL is commercially available (see Fiedler, Lexicon of auxiliary materials 1971, page 320). The galenic mixtures of the antibiotic S 7481 / F-1 according to the invention are prepared by adding 10-50 mg of the antibiotic in 0.5 ml of Labrafil, preferably in 0.2 ml of the transesterified nonionic triglycerides at temperatures of 16-40 "C. especially at room temperature.
The solution thus obtained is then filled into bottles or ampoules for oral or parenteral administration.
The mixture listed under d) contains the transesterified nonionic triglycerides or ethyl oleate, lecithins, such as z. B. isolated soy phospholipids in soybean oil (e.g. Epikuron 125) and water, and is preserved with a preservative (e.g. with nipakobin, a mixture of 65% p-hydroxy-benzoic acid methyl ester and 35% p-hydroxybenzoic acid propyl ester in a ratio of 0.05 to 0.09%, preferably 0.08%).
The composition suitable for oral administration is obtained by combining the antibiotic (1 mg) in the mixture of one or more lecithins and transesterified nonionic triglycerides or ethyl oleate, which still contains an inert solvent, for example a pharmaceutically acceptable lower alcohol such as e.g. B. ethanol, in a ratio of 1 to 10 based on the above.
Mixture was added, dissolved at temperatures of 18 to 30 ° C., preferably at room temperature, then the other additives, for example preservatives, were added and the solution was mixed with water and homogenized using a homogenizer. The emulsion obtained became an oral Bottled administration.
The neutral oil specified under e), for example triglyceride based on saturated vegetable fatty acids with chain length C8 to C12 (Miglyol 812), is mixed with the antibiotic S 7481 / F-1 at temperatures of 16 to 40 C, preferably at room temperature, whereby for 1 g antibiotic from 5 to 50 ml, preferably 10 ml, neutral oil can be used. In the preparation of the mixture, the presence of a solvent, e.g. B. benzoic acid benzyl ester (see Fiedler, Lexicon of auxiliary materials 1971, page 79), 1.2 butylene glycol l-methyl ether (Soluphor CE 5151) or ethanol in a proportion of 2 to 15% is appropriate. The resulting composition is filled into ampoules for parenteral administration.
The compositions according to the invention, moreover, the usual additives such. B. preservatives, are characterized in that they allow good absorption of the usually difficult to absorb antibiotic S 7481 / F-1.
The compositions according to the invention can be administered in the following galenic forms:
A) Drinking solutions
B) drinking emulsions or
C) Parenteral injection solutions.
The following compositions are preferably administered as drinking solutions:
1) antibiotic S 7481 / F-1 and sesame oil, optionally together with the additives described under bd),
2) Antibiotic S 7481 / F-1 and ethyl oleate and a surfactant specified under b).
These drinking solutions may also contain ethanol in a proportion of 1% to 15%.
In particular, a composition consisting of the antibiotic S 7481 / F-1, a transesterified nonionic triglyceride, in particular Labrafil, and a lecithin, in particular isolated soy phospholipids in soybean oil, is used as the drinking emulsion. This composition also contains 2 to 10% ethanol and 50 to 80% water.
The following compositions are preferably administered as parenteral injection solutions:
3) antibiotic S 7481 / F-1 and sesame oil, optionally together with the additives described under b} d),
