Viagra for Women

Scientists move closer to creating equivalent of male Viagra for women.
The Los Angeles Times (4/14, Mestel) "Booster Shots" blog reported that "when Viagra [sildenafil] was first marketed, some sexual health experts suggested that it might work in women as well as men, providing a pharmacological aid for women with low levels of arousal (sometimes termed 'female sexual dysfunction' or 'female sexual arousal disorder')." Women haven't had great success with the little blue pill, however, which suggests "there's something about arousal in male versus female parts that differs physiologically." Now, however, researchers at Pfizer say they've made headway in finding a drug that could help some women with FSAD.
According to an article on the ABC News (4/14, Hutchinson) website, the breakthrough came courtesy of rabbits. Researchers administered a drug known as UK-414,495 to female rabbits and it appeared to "mimic the human body's natural processes in bolstering" excitement. "By specifically blocking the enzyme in the body that checks blood flow to" female genitalia, "the drug could allow for greater blood flow and greater physiological arousal, said Chris Wayman, the lead researcher on the project" that is detailed in the British Journal of Pharmacology. The "drug would not create arousal out of nowhere," but it will "boost blood flow when accompanied by desire and sexual stimulation."
