Abstract

The present invention is directed to a liposome composition for use in the peritoneal dialysis of patients suffering from endogenous or exogenous toxicopathies, wherein the pH within the liposomes differs from the pH in the intraperitoneal cavity and wherein the pH within the liposome results in a liposome-encapsulated charged toxin. The invention also relates to a pharmaceutical composition comprising said liposomes. A further aspect of the present invention relates to a method of treating patients suffering from endogenous or exogenous toxicopathies, preferably selected from drug, metabolite, pesticide, insecticide, toxin, and chemical warfare toxicopathies, more preferably hyperammonemia, comprising the step of administering liposomes of the invention in a therapeutically effective amount into the peritoneal space of a patient in need thereof. Next to human, the present invention is particularly suitable to veterinary aspects.
