Abstract: The present invention refers to a set for the production of a ready-to-use chemo-therapeutic composition for intraperitoneal administration as an aerosol, wherein the set comprises an aqueous concentrate containing at least cisplatin in a first predetermined concentration and doxorubicin in a second predetermined concentration with a predetermined ratio of the first and the second concentration and having a pH value in the range from 3.0 to 7.0. The set further comprises a physiological aqueous carrier solution, which is for optional dilution of the concentrate depending on target concentrations of cisplatin and doxorubicin in the chemo-therapeutic composition to be applied. Further, the invention refers to a method for providing of a ready-for-use chemotherapeutic composition for intraperitoneal administration as an aerosol by using of a set, to a chemotherapeutic composition for intraperitoneal administration as an aerosol, and a use of the chemotherapeutic composition.
