Abstract: The invention relates to the use as medicaments, specifically as antiinflammatories, of complexes formed by cationic liposomes and polydeoxyribonucleotides having a molecular weight in the range 7,000-60,000 Da obtainable by depolymerization of nucleic acids, wherein in said complexes the polydeoxyribonucletoides are located on the outer surface of the liposome.
