Researchers at the Medical College of Georgia report that another closer look should be given to three drugs that are used to treat male impotence to see if small modifications could be made to render the treatments effective in women who experience sexual dysfunction.
Researchers studied the effects of three Type-5 inhibitors, Viagra, Levitra and Cialis, and found that the drugs relaxed the artery in both male and female rats.
This finding suggests that small alterations could make the drugs viable for women as a way of treating sexual dysfunction.
Hope for a little pink-pill counterpart to men's blue pills was given up when early clinical trials showed no response in women.
"This research shows the drugs need to be investigated more for women and small alterations could make these compounds more effective for women living with these disorders," says Dr. Kyan J. Allahdadi, postdoctoral fellow in physiology at MCG in a press release.
Allahdadi will be presenting the findings at the 122nd Annual Meeting of the American Physiological Society in New Orleans, April 18-22 as part of the Experimental Biology 2009 conference.
