Women's sex pill turns out to be an anti-climax

US health regulators said yesterday that the first pill designed to boost the female sex drive failed to make a significant impact on libido in two studies.

  • Go To

Despite missing that goal, the Food and Drug Administration said women did report slightly more satisfaction in their sexual experiences.

Boehringer Ingelheim has asked the FDA to approve its drug flibanserin for women who report a lack of sexual desire -- a market that drug makers have been targeting for more than a decade since the success of Viagra in men.

The search for so-called "female Viagra" has proved elusive, with many drugs abandoned after lacklustre results.

Tomorrow, the FDA will ask a panel of experts to weigh in on the safety and effectiveness of Boehringer's drug.

The FDA will also ask experts to comment on increased side-effects like depression, fainting and dizziness.



Chemicals

The drug, which is related to the anti-depressant family, affects serotonin and several other brain chemicals, though it is not clear how that increases sex drive.

Since the launch of Viagra in 1998, more than two dozen experimental therapies have been studied for so-called "female sexual dysfunction", a market that some analysts estimate at $2bn (€1.6bn).

In 2004, Pfizer halted its study of Viagra in women due to inconclusive results. Later that year, an FDA panel rejected Procter & Gamble's testosterone patch Intrinsa, due to risks of heart disease and cancer.

Smaller companies are developing creams and even nasal sprays to increase female libido.

Elizabeth Kavaler, a urologist at Lenox Hill Hospital in New York, says it may be unrealistic to expect a pill to completely address sexual problems.

"It's a fairly complicated area, unlike in men's sexual dysfunction where there's a major mechanical concern," said Dr Kavaler. "In women there's no mechanical concern, so if she's not having a successful sex life, where is the problem?"
