The drug, which is being developed by Shionogi Pharma, has been tested with 556 men, with a total of 23,000 exposures during a period of three months. The spray gets directly applied to the glans five minutes before the sexual intercourse. The studies have showed that the intercourse went from 0.6 minutes to 3.3 minutes. Those subjects receiving the placebo went from the same 0.6 average to 0.9 minutes.
The drug had side effects on a small percentage of the test population: 3.1% of men had loss of erection, while 5% of women that had intercourse suffered a burning sensation. [Renal & Urology News]
