          Abstract

          Background

          Premature ejaculation (PE) is considered to be the most common male sexual disorder affecting 20% to 66% of sexually active men. Most of the patients had already tried on demand dapoxitine with no improvement. We aimed in the current study to assert the efficacy and safety profile of daily intake of 30 mg duloxetine in treating patients with lifelong premature ejaculation (LPE) as well as patients with acquired premature ejaculation (APE).

          Results

          The current study showed significant improvement in intravaginal ejaculatory latency time (IELT) after intake of duloxetine. All participants had a median Arabic index of premature ejaculation (AIPE) of 26, median IELT of 180 s, median male sexual quality of life (SQOL) of 43 after being treated with duloxetine ( p value < 0.001 for all). While median AIPE after placebo was 19, median IELT after placebo was 60 s and median male SQOL after placebo was 21. Paired comparison of AIPE, IELT (Secs), inter quartile range (IQR) and male SQOL in group (A) patients at baseline and after duloxetine intake showed statistically significant improvement among treated patients ( p values < 0.001 for all). Paired comparison of AIPE, IELT (Secs), IQR and male SQOL in group (A) patients at baseline and after placebo treatment showed no significant improvement of male SQOL. Furthermore, AIPE and IELT returned to baseline scores after discontinuation of duloxetine ( p values 0.729; 0.892, respectively). Paired comparison of AIPE, IELT (Secs), IQR and male SQOL in group (B) patients at baseline and after placebo treatment showed almost same scores of patients in group (A) who received placebo for 2 months after a 2 month washout period ( p values 1.000 for all).

          Paired comparison of AIPE, IELT (Secs), IQR and male SQOL in group (B) patients at baseline and after duloxetine treatment showed statistically significant improvement among all treated patients ( p values < 0.001 for all).

          Conclusion

          Duloxetine is an effective drug for treatment of LPE and APE patients. Further, larger studies are needed to compare duloxetine to different known therapeutic modalities for PE to assert it’s efficacy and superiority.

          Résumé

          Contexte

          L’éjaculation précoce (EP) est considérée comme le trouble sexuel masculin le plus courant, touchant 20% à 66% des hommes sexuellement actifs. La plupart des patients avaient déjà essayé la dapoxitine à la demande sans amélioration. Dans la présente étude, nous avons cherché à déterminer l’efficacité et l’innocuité de l’apport quotidien de 30 mg de duloxétine comme traitement de patients atteints d’éjaculation précoce de longue durée et de patients atteints d’éjaculation précoce acquise.

          Résultats

          La présente étude a montré une amélioration significative du temps de latence éjaculatoire intravaginal (IELT) après la prise de duloxétine. Tous les participants avaient un indice médian de l’éjaculation précoce (AIPE) de 26, un IELT médian de 180 secondes, et une médiane de la qualité de vie sexuelle masculine (SQOL) de 43 après avoir été traités par la duloxétine ( p < 0,001 pour tous). Après placebo, l’AIPE médian était de 19, l’IELT médian de 60 secondes et la médiane de la SQOL masculine de 21. La comparaison appariée de l’AIPE, de l’IELT, de l’intervalle interquartile (IQR) et de la SQOL masculine chez les patients du groupe (A) au départ et après la prise de duloxétine a montré une amélioration statistiquement significative chez les patients traités ( p < 0,001 pour tous). La comparaison appariée de l’AIPE, de l’IELT, de l’IQR et de la SQOL masculine chez les patients du groupe (A) au départ et après traitement par placebo n’a montré aucune amélioration significative de la SQOL masculine. De plus, l’AIPE et l’IELT sont revenus aux scores de base après l’arrêt de la duloxétine (respectivement p 0,729; 0,892).

          La comparaison appariée de l’AIPE, de l’IELT, de l’IQR et de la SQOL masculine chez les patients du groupe (B) au départ et après traitement par placebo a montré presque les mêmes scores que les patients du groupe (A) qui ont reçu un placebo pendant 2 mois après une période de sevrage thérapeutique de 2 mois (p 1,000 pour tous). La comparaison appariée de l’AIPE, de l’IELT, de l’IQR et de la SQOL masculine chez les patients du groupe (B) au départ et après le traitement par la duloxétine a montré une amélioration statistiquement significative chez tous les patients traités ( p < 0,001 pour tous).

          Conclusions

          La duloxétine est un médicament efficace pour traiter des patients atteints d’éjaculation précoce de longue durée, et ceux atteints d’éjaculation précoce acquise. D’autres études de plus grande envergure sont nécessaires pour comparer la duloxétine aux différentes modalités thérapeutiques connues de l’éjaculation précoce, afin de déterminer son efficacité et sa supériorité.

              An Evidence-Based Unified Definition of Lifelong and Acquired Premature Ejaculation: Report of the Second International Society for Sexual Medicine Ad Hoc Committee for the Definition of Premature Ejaculation

              Introduction The International Society for Sexual Medicine (ISSM) Ad Hoc Committee for the Definition of Premature Ejaculation developed the first evidence-based definition for lifelong premature ejaculation (PE) in 2007 and concluded that there were insufficient published objective data at that time to develop a definition for acquired PE. Aim The aim of this article is to review and critique the current literature and develop a contemporary, evidence-based definition for acquired PE and/or a unified definition for both lifelong and acquired PE. Methods In April 2013, the ISSM convened a second Ad Hoc Committee for the Definition of Premature Ejaculation in Bangalore, India. The same evidence-based systematic approach to literature search, retrieval, and evaluation used by the original committee was adopted. Results The committee unanimously agreed that men with lifelong and acquired PE appear to share the dimensions of short ejaculatory latency, reduced or absent perceived ejaculatory control, and the presence of negative personal consequences. Men with acquired PE are older, have higher incidences of erectile dysfunction, comorbid disease, and cardiovascular risk factors, and have a longer intravaginal ejaculation latency time (IELT) as compared with men with lifelong PE. A self-estimated or stopwatch IELT of 3 minutes was identified as a valid IELT cut-off for diagnosing acquired PE. On this basis, the committee agreed on a unified definition of both acquired and lifelong PE as a male sexual dysfunction characterized by (i) ejaculation that always or nearly always occurs prior to or within about 1 minute of vaginal penetration from the first sexual experience (lifelong PE) or a clinically significant and bothersome reduction in latency time, often to about 3 minutes or less (acquired PE); (ii) the inability to delay ejaculation on all or nearly all vaginal penetrations; and (iii) negative personal consequences, such as distress, bother, frustration, and/or the avoidance of sexual intimacy. Conclusion The ISSM unified definition of lifelong and acquired PE represents the first evidence-based definition for these conditions. This definition will enable researchers to design methodologically rigorous studies to improve our understanding of acquired PE.
