    There is some speculation about whether the drugs could delay orgasm in men with normal sexual function — potentially creating an even larger lifestyle market. Jon Pryor, chairman of the University of Minnesota urology department and the principal investigator on the dapoxetine study, says he believes the drug could potentially delay ejaculation in the general male population, though a potential downside could be an inability to achieve orgasm at all. Johnson & Johnson says it is testing the drug strictly on men diagnosed with premature ejaculation and will market it only to that group if it is approved.

    Drug makers face some challenges if they want these new drugs to rival the likes of Pfizer’s Viagra, which passed the $1 billion sales mark within a year. A report by Merrill Lynch on Johnson & Johnson’s drug pipeline estimated that U.S. sales of dapoxetine in 2008 could range from $350 million to $1.15 billion.

    Dapoxetine didn’t significantly improve the sex lives of everyone who tried it in the study. Less than 50% of the dapoxetine study participants reported "good" or "very good" satisfaction with sex at the end of the study.

    One challenge for drug companies, doctors and patients is defining what constitutes "premature." A recent study in the Journal of Sexual Medicine sponsored in part by Johnson & Johnson attempted to define the problem by giving stopwatches to the wives and girlfriends of 1,587 men, and asking them to measure the period between penetration and ejaculation. Men who considered themselves "normal" averaged 7.3 minutes. Men who considered themselves "premature" averaged 1.8 minutes. But the study also found that anxiety over the issue varied greatly.

    "The number of men who want to be treated for PE is far less than the men who report having it," says Ira Sharlip, a urologist and spokesman for the American Urological Association.

    Johnson & Johnson is confident there will be a market for the drug. "There’s a lot of cynicism out there about if this really is a condition or not," says Usman Azam, the company’s vice president of urology drug research and development. But he notes that 10 years ago, people thought the same way about impotence.

    Dapoxetine works in a similar manner to SSRI (selective serotonin reuptake inhibitors) antidepressants like Paxil, which regulate levels of the neurotransmitter serotonin in the brain — but it works much faster and can be taken one to three hours before sex. Ongoing research suggests that changes in serotonin metabolism in the central nervous system may be responsible for the timing of ejaculation. Ironically, SSRI antidepressants are known to have sexual side effects such as damping libido. But the sexual side effects may be less-pronounced in a short-acting pill.

    Pfizer is also testing a short-acting SSRI to treat premature ejaculation. The experimental drug had progressed to the early clinical trial stage in 2003, according to a review of research projects the company released that year. A Pfizer spokesman declined to give an update on the project but said the company "is conducting studies." Several smaller companies are also working on pills, including Enhance Biotech of North Carolina.

    Some doctors have also been studying whether impotence drugs could help men with premature ejaculation. The results are mixed. While one study suggested sildenafil citrate, the active ingredient in Viagra, can delay ejaculation, a more recent study found the drug did not. (Even with Viagra, men lose their erection after ejaculation.) The new Johnson & Johnson-funded study on dapoxetine involved 2,614 men age 18-77 in stable, heterosexual relationships. All were diagnosed with premature ejaculation. (That meant they typically ejaculated in under two minutes after sex started and felt considerable distress over the issue.) One group took a 30-milligram dose of the drug, another group took a 60-milligram dose, and a third group took a placebo. Wives and girlfriends timed intercourse with a stopwatch over a 12-week period.

    Men taking the highest dose of the drug were able to last for just over three minutes, up from an average of 55 seconds. But they also had the highest rate of side effects: About one in five experienced nausea and 6%-7% experienced headache, diarrhea or dizziness. Side effects were milder at the 30-milligram dose. On that dose, men were able to delay ejaculation to about 2.8 minutes. Men in the placebo group were able to delay ejaculation slightly — to about 1.8 minutes

    No; it does neither.
    It simply increases the ability to achieve and/or maintain an erection, & may help increase ejaculation by having a stronger erection.
