  • Patent number: 6696428
    Abstract: The side effect of decrease in body weight caused by the alkylphosphocholines such as miltefosine can be antagonized by certain acetylcholine receptor antagonists such as domperidone and pimozide. The combination of alkylphosphocholine plus the antagonist does not have any effect on the anti-tumor action of the alkylphosphocholine. The combination also caused no new side effects in the animals.

  • Publication number: 20030040507
    Abstract: The invention relates to the use of a combination of ifosfamide and carnitine, in particular L-carnitine, for the production of tumour pharmaceuticals having decreased side effects. The results show clearly that the side effect produced by ifosfamide (damage to the proximal tubule of the kidney) is antagonized in animals by L-carnitine. It was furthermore possible to show that the antitumour action of ifosfamide is not affected in combination with L-carnitine. The combination also caused no new side effects in the animals.
