New study will examine Mefloquine as a Treatment for Malignant Glioma (Brain Cancer). Mefloquine is designed to block a protein that helps to clean the waste in the cells and to destabilize the cell membrane. Blocking this protein may cause tumor cell death. (Study registered in September 2011)

“Given that such individuals will not be ill on departure, and that anti-malria use is prophylactic, the prescribed agent should enjoy a very low risk-benefit ratio, i.e. prophylactic antimalarials should be very well tolerated.”

Mefloquine Induces Dose-Related Neurological Effects in a Rat Model. GS Dow et al., Walter Reed Army Institute of Medical Research (WRAIR), March 2006. This study documents that at treatment levels, the concentration of mefloquine in the bloodstream (reached in women after the 4th or 5th preventive dose) “caused degeneration of specific brain stem nuclei.” Also see Dow’s earlier research (below) which further documents mefloquine’s neurotoxicity.

Malaria drug blocks brain conduits. Brown University Press Release. Brown researchers have discovered that mefloquine, an anti-malarial drug, blocks two gap junction proteins, or connexins, in low doses and with very few side effects in the brains of laboratory mice. The work opens an important door: Connexins found in high concentrations in the brain are believed to play a critical role in movement, vision and memory. August 7, 2004. Study follows.
