  • PHARMACEUTICAL COMPOSITION HAVING ACTIVITY OF ANTICANCER
    Publication number: 20140235558
    Abstract: Disclosed is an anticancer pharmaceutical composition comprising phenformin or a pharmaceutically acceptable salt thereof, and a glycolysis inhibitor, particularly, 2-deoxy-D-glucose as active ingredients. These ingredients act in synergy with each other, thus exhibiting more potent inhibitory activity against the growth of cancer cells, compared to individual ingredients. Also, the synergistic anticancer activity allows the individual drugs to be used in lower amounts, which leads to a reduction in the occurrence of adverse effects. In addition, the time-lag release or administration of the ingredients decreases blood lactic acid levels to significantly mitigate the adverse effect of lactic acidosis, as well as exerting high anticancer effects. Particularly, the pharmaceutical composition can be formulated to dosage forms effective for therapy, increasing the drug compliance of the subject.
