Selective serotonin reuptake inhibitors in the treatment of premature ejaculation / 中华医学杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To review and assess the update studies regarding selective serotonin reuptake inhibitors (SSRIs) in the treatment of premature ejaculation (PE) and then provide practical recommendations and possible mechanisms concerning state of the art knowledge for the use of SSRIs in alleviating PE.</p><p><b>DATA SOURCES</b>Using the Medline, 48 articles published from January 1st, 1996 to August 1st, 2006 concerning the use of SSRIs and their possible mechanisms in alleviating PE were found and reviewed.</p><p><b>STUDY SELECTION</b>PE, rapid ejaculation, early ejaculation and SSRIs were employed as the keywords, and relevant articles about the use of SSRIs and their possible mechanisms in the treatment of PE were selected.</p><p><b>RESULTS</b>Many kinds of SSRIs, such as fluoxetine, sertraline, paroxetine and citalopram, have widely been employed to treat PE. However, their effects are moderate and there is no a universal agreement about the kind, dose, protocol and duration. Dapoxetine, as the first prescription treatment of PE, may change this bottle-neck situation. SSRIs are suggested to be used in young men with lifelong PE, and acquired PE when etiological factors are removed but PE still exists. Phosphodiesterase 5 inhibitors (PDE(5)-Is) are suggested to be employed alone or combined with SSRIs when SSRIs fail to treat PE or sexual dysfunction associated with SSRIs occurs. The protocol of taking drugs on demand based on taking them daily for a suitable period is proposed to be chosen firstly. The possible mechanisms include increasing serotonergic neurotransmission and activating 5-hydroxytryptamine 2C (5-HT(2C)) receptors, then switching the ejaculatory threshold to a higher level, decreasing the penile sensitivity and their own effect of antidepression.</p><p><b>CONCLUSION</b>The efficacies of the current SSRIs are moderate in the treatment of PE and they have not been approved by the FDA, therefore new SSRI like dapoxetine needs to be further evaluated.</p>
