title: [The in vitro and in vivo stability of the entrapment of methotrexate in negatively charged liposomes after sterile filtration (author's transl)].
abstract: The preparation of sterile artificial liposomes (phosphatidylcholine:cholesterol:dicethylphosphate=5:5:1) by Millipore filtration is described. Conditions for storing liposome entrapped Methotrexate have been found which allow storage of the drug in the entrapped form over a period of at least 4 months. It is shown that intravenously injected liposome entrapped Methotrexate is retained for at least 15 hours in the particulate form. During this time no free Methotrexate is detectable in the blood.
