Originally developed as an anti-depressant, Dapoxetine succeeds in a slightly different way to the one planned- it can be used as a treatment for premature ejaculation, making a man last up to three times longer than usual.
The men in the trial were all in monogamous sexual relationships. Before taking the drug, they typically lasted less than a minute in the sexual act. On the highest dose of the drug, patients lasted around 3 minutes 20 seconds, the company reported.
Just over half of the men who took the drug described the control they had over their ejaculation as “fair” to “very good”, compared to about 3% of those who did not take the treatment. The number of men describing the sexual satisfaction as “good” to “very good” almost doubled to 46.5%. Their sexual partners reported a similar experience.
