Snorting sex

A new drug for sexual dysfunction–for both men and women–isn’t a little blue pill or terrifying suction cup.
PT-141, about to enter clinical trials, is taken via nasal spray. I’m hot already.

PT-141 has been tested on 900 volunteers who have since reported enhanced arousal and desire in as few as 15 minutes after taking the drug.
…PT-141 acts on the brain to jump-start desire, which in turn can cause increased genital blood flow in men and women.

Is it just me or does the vague “acts on the brain” explanation of the drug seem a little freaky?
