Levitra & Viagra Help Brain Tumors Treatment
Neurologists at Cedars-Sinai Medical Center in Los Angeles discovered that pairing chemotherapy with Levitra and Viagra improved the chemo’s ability to reach brain tumors in rats. Tests in rats showed two erectile dysfunction drugs helped carry a chemotherapy drug past the blood-brain barrier, they said.
Levitra and Viagra, known generically as sildenafil, are in a class of drugs known as PDE5 inhibitors. They were originally tested as heart drugs because they increase blood flow in small vessels.
Animals that got both drugs had smaller tumors and lived longer than rats that got chemo alone. Makes sense. Erectile dysfunction drugs work by increasing blood flow to the penis. The same process seems to speed life-saving medicines to the brain.
