Pharmaceutical administration systems containing a mixture of immunomodulators

摘要

The present invention relates to pharmaceutical administration systems containing phosphatidylserine and phosphatidylcholine or phosphatidylethanolamine derivatives in the form of liposomes which encapsulate water soluble muramyldipeptide derivatives in combination with gamma-interferon. The liposomes are prepared by conventional dispersion methods. The pharmaceutical administration systems when applied in the form of liposomes are especially useful in the cancer chemotherapy for combating metastatic tumor cells.
