Producers of a new Viagra-type medicine for women say that the pill will boost female sex drive and reduce appetite, Newsmax Health reports.

The drug, which is still undergoing clinical trials, is essentially a synthetic version of melatonin and acts on the brain to boost sexual desire, the report says. Women take it 15 minutes before sexual activity, and the pill can keep the engine revving for more than two hours.

Another new drug on the horizon offering the same promise is Lybridos, created by Dutch and

U.S. firm Emotional Brain. The pill, which could be on sale within three years, contains testosterone and targets areas of the brain related to sexual desire, the company says.

Meanwhile, Pfizer's Viagra for men is a global sensation, with the company even selling it online for $25 to counter the fierce online trade in counterfeit pills.
