Description

Verfahren zur Herstellung von Suspensionen von Penicillinsalzen Es wurde gefunden, daR man zu hochkonzentrierten, leicht flielBenden wäßrigen Suspensionen von schwer löslichen Penicillinsalzen rganischer Basen gelangen kann, wenn man den Penicillinsalzen Galle oder Zubereitungen aus Galle, wie gereinigte Ochsengalle (Fel tauri depuratum), ferner Gallensäuren, z. B. Desoxycholsäure, vorzugsweise in Form wasserlöslicher Salze zusetzt.Process for the preparation of suspensions of penicillin salts It it has been found that highly concentrated, easily flowing aqueous suspensions are obtained of sparingly soluble penicillin salts of organic bases, if one has the Penicillin salts of bile or preparations made from bile, such as purified ox bile (Fel tauri depuratum), also bile acids, z. B. deoxycholic acid, preferably added in the form of water-soluble salts.

Die Menge der erfindungsgemäß zu verwendenden Zusatzstoffe läßt sach durch Vofversuche leicht ermitteln, sie hängt häufig von der Korngröße des p-Aminobenzoyldiäthylaminoäthanol-Penicillins ab; im allgemeinen genügen Zusätze von O,I bis 1 0/o. The amount of the additives to be used according to the invention can be considered Easily determined by trial tests, it often depends on the grain size of the p-aminobenzoyl diethylaminoethanol penicillin away; In general, additions of 0.1 to 10% are sufficient.

Zur Erhöhung der Haltbarkeit können in an sich beliannter Weise noch Puffer zugesetzt werden. Da die Suspensionen so flüssig sind, daß sie zum Absetzen neigen, werden zweckmäßig Verdickungsmittel, wie Celluloseäther, Na-Alginat, Traganth, Polyvinylpyrrolidon usw. zugesetzt. In order to increase the shelf life, you can still use Buffers can be added. Because the suspensions are so fluid that they have to settle tend to use thickeners such as cellulose ether, sodium alginate, tragacanth, Polyvinylpyrrolidone, etc. added.

Beispiel I I g p-Aminobenzoyldiäthylaminoäthanol-Penicillin werden in 2 ccm einer o,0/0igen Lösung von Ochsengalle in Wasser suspendiert. Example I I g of p-aminobenzoyl diethylaminoethanol penicillin will be suspended in 2 cc of a 0.0 / 0 solution of ox bile in water.

Beispiel 2 1 g p-Aminohenzoyldiäthylaminoäthanol-Penicillin werden in 2 ccm einer Lösung von 0,2°/o Ochsengalle und 0,5 0/0 Polyvinylpyrrolidon in Wasser suspendiert. Example 2 1 g of p-Aminohenzoyldiäthylaminoäthanol-penicillin become in 2 cc of a solution of 0.2% ox gall and 0.5% polyvinylpyrrolidone in Suspended in water.

Beispiel 3 1 g p-Aminobenzoyldiäthylaminoäthanol-Penicillin werden in 2 ccm einer o,7°/oigen Lösung von desoxycholsaurem Natrium in Wasser suspendiert. Example 3 1 g of p-aminobenzoyl diethylaminoethanol penicillin are used suspended in 2 cc of a 0.7% solution of sodium desoxycholate in water.

Beispiel 4 1 g p-Aminobenzoyldiäthylaminoäthanol-Penicillin werden in 2 ccm einer Lösung von Ochsengalle und 0,I0/o Gummiarabikum in Wasser suspendiert. Example 4 1 g of p-aminobenzoyl diethylaminoethanol penicillin are used suspended in 2 cc of a solution of ox bile and 0.110 / o gum arabic in water.

Beispiel 5 1 g des Salzes aus Penicillin und 3-n-Butoxy-Nisobutylhenzylamin werden in 4 ccm einer 1%igen wäßrigen Lösung von gereinigter Ochsengalle (Fel tauri depuratum) suspendiert. Example 5 1 g of the salt of penicillin and 3-n-butoxy-nisobutylhenzylamine are in 4 ccm of a 1% aqueous solution of purified ox bile (Fel tauri depuratum).

In allen Fällen erhält man leicht fließende, gut injizierbare Suspensionen. Easily flowing, readily injectable suspensions are obtained in all cases.
