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'-methylenediphenol and 30 g of DMSO, completed with di-n-butyl adipate to 100 cm.sup.3.
