The present invention relates to a preparation method of liposome as anticancer medicine, whose targetable drug-applied ratio is closed to 100% (direct injection to cancerism). Because three layers (internal, intermediate and external) of the sain liposome are treated specially, so that said liposome is applicable to industrialization production, and as thickening and slow-releasing measures are taken for said liposome, when the drug is directly applied to the focus, its orientation effect is good and action time is long. |
