It was by chance that they discovered its ability to treat premature ejaculation, actually developed to treat depression. In this electronic resource (e-source), we’ll use the Viagra™ story to show how a medicine is designed, developed and produced As an active ingredient in Priligy, Buy Levitra With Dapoxetine hydrochloride belongs to the class of medicines called selective serotonin reuptake inhibitors (SSRIs) with a short half-life of 1 or 2 hours, it is considered safe and sound for the treatment of premature ejaculation.

Like Prozac and other antidepressants such as Zoloft, Escitalopram and Paxil, dapoxetine is SSRI. In fact, considering the drug’s early development over a decade ago, Eli Lilly began phase I clinical trials for dapoxetine as an antidepressant medication. But dapoxetine was put on hold for a while and didn’t pan out as an antidepressant. But the same thing that leads to its failure as a psychopharmaceutical turned out to be the cause for its success as a premature ejaculation treatment.
Dapoxetine as a SRRI

But, as these antidepressants for treating this condition are not approve by the FDA, this is consider for “off label” use. As unlike other SSRIs, dapoxetine is easily and rapidly absorbed and eliminated by the body i.e. within few hours, rather than days. It was Karl Thor an Eli Lilly researcher who realized the drug’s potential as a treatment particularly for premature ejaculation. Due to its short residence in the body, it is consider unfeasible as an antidepressant. But on the other hand makes it more suitable for treating premature ejaculation. Eli Lilly resumed several trials with the remedy, but this time as a treatment for premature ejaculation.
