  • Patent number: 8828972
    Abstract: The invention relates to novel medicament formulations containing, as active ingredients, alkylphosphocholines and the like, alkyl-alkanediol-phosphocholines and the like, and (ether)lysolecithins and the like, in different forms of embodiment. The active ingredients are integral constituents of liposomes, also containing cholesterol and the like and a negative charge carrier. The medicament formulations are especially suitable for the treatment and/or prophylaxis of cancer, protozoan diseases such as leishmaniasis and amoebic diseases, acariasis and diseases caused by arthropods, and bacterial diseases, such as ehrlichiosis. Ocular diseases accompanied by uncontrolled cellular processes can also be advantageously influenced.

  • Publication number: 20030139459
    Abstract: A veterinary preparation for fleas is described, which consists of an amount that is effective against fleas of a combination of a compound of formula (I), wherein R1 hydrogen, C1-C6-alkyl or C3-C7-cycloalkyl; R2 is hydrogen, C1-C6-alkyl or C3-C7-cycloalkyl; R3 is hydrogen or C1-C6-alkyl; and A is heterocycly which is unsubstituted or substituted once or repeatedly by identical or different halogen atoms; and a compound of formula (II), wherein X is halogen, X1 is hydrogen or halogen; X2 is hydrogen or halogen; Y is partially or completely halogenated C1-C6-alkoxy, or partially or completely halogenated C1-C6-alkoxy which is interrupted by one oxygen atom, or partially or completely halogenated C2-C6-alkenyl; Y1 is hydrogen or halogen; Y2 is hydrogen or halogen; Y3 is hydrogen or halogen; Z1 is hydrogen or C1-C3-alkyl; and Z2 is hydrogen or C1-C3-alkyl; and a physiologically acceptable formulation excipient.
