The invention relates to a solvent vehicle for therapeutics comprising a dialkyl ester of adipic acid and, optionally, DMSO, which is particularly useful for therapeutic materials having a low solubility or being insoluble in water.
The invention further relates to pharmaceutical compositions which are suitable for parenteral administration, especially by intramuscular injection, comprising a therapeutically active material dissolved in said solvent vehicle.
Solvent vehicles containing di-n-butyl adipate and DMSO, and, if desired, one or more adjuvants, are preferred.
Particularly useful are pharmaceutical compositions for the prophylaxis and or treatment of diseases caused by internal parasites, which can be administered by intramuscular injection. A preferred embodiment of the invention is an injectable composition against distomatosis (liver fluke disease) containing proportionally 12.5 g 4,6'-dichloro-4',6-dinitro-2,2'-methylene-diphenol and 30 g of DMSO, completed with di-n-butyl adipate to 100 cm3,
