Anti-diarrhea drug triggers cell death in glioblastoma cells

In cell culture, loperamide, a drug commonly used against diarrhea, proves effective against glioblastoma cells. A research team at Goethe University has now unraveled the drug’s mechanisms of action of cell death induction and – in doing so – has shown how this compound could help attack brain tumors that otherwise are difficult to treat.
