Scientists have created a drug which enhances a man’s sex drive.

The drug is specifically aimed at men who experience impotence (erectile dysfunction).

It is not the same as Viagra. Called PT-141, it does not target the symptoms of impotence. Rather, it increases the man’s libido � sex drive.

The drug should be administered 30 minutes before sex. The person sprays it into his nose.

It is a copy of melanocyte-stimulating hormone.

In clinical trials, researchers say it has been effective in 70% of volunteers.

If all goes according to plan this drug should be on the market in the year 2008.

Plans are also in the pipeline to experiment with a cocktail that would include Viagra and PT-141. This may help men who do not respond to any treatment available today.

The manufacturers also said that they are planning to test a new drug that may increase a woman’s sex drive.
