After a quality validation, only seven studies9,10,11,12,13,14,15 were selected from the literature search.
Of the 95 participants who completed follow-up, 64% maintained satisfactory ejaculation control at 24 months and 56% did so at 36 months. Surgical procedures that reduce penile sensation have been proposed as treatments for premature ejaculation. These include selective dorsal nerve neurotomy, pulsed radiofrequency ablation or cryoablation of dorsal penile nerves, and hyaluronic acid gelaugmentation of the glans penis. [61, 62] Currently, all those are considered experimental. Before the availability of nonsurgical methods for treating erectile dysfunction, a patient with premature ejaculation who was mistakenly diagnosed with erectile dysfunction might have undergone a penile prosthesis implantation, which would have yielded unsatisfactory results because of the incorrect initial diagnosis.
In this scenario, the patient would be able to engage in sexual intercourse, because the penile implant would provide an adequate erection, but he would still climax prematurely. Currently, penile implants are placed much more rarely, and with the use of nonsurgical treatments for erectile dysfunction, any permanent harm resulting from diagnosing erectile dysfunction rather than premature ejaculation is unlikely. Consultation with a sex therapist, psychologist, or psychiatrist may prove helpful if the primary care physician or urologist cannot provide successful treatment or does not have the time to explore psychological issues and implement behavioral techniques (eg, squeeze-pause). If the primary care physician or urologist is inexperienced or uncomfortable with treating premature ejaculation, early referral to a sex therapist, psychologist, or psychiatrist is indicated. Some physicians are comfortable implementing pharmacologic therapy but not behavioral therapy.
As with any medical condition, the patient should be offered all available treatment options, and the physician should proceed with referral for any option considered to require more specialized help than the physician can provide. For men who may have a severe emotional disturbance underlying the premature ejaculation, referral to a mental health professional is most appropriate. Diagnosis and treatment of the various psychological factors that manifest partly as premature ejaculation are beyond the scope of this discussion. Premature ejaculation (PE) is the most common male sexual dysfunction. Dapoxetine hydrochloride, belonging to a class of drugs known as selective serotonin reuptake inhibitors or, was the first drug originally approved for the on-demand treatment of men with PE. The flow chart of the evidence acquisition process is summarized in Figure 1 and the methodological quality of the included studies is reported in Figure 2. Seven randomized controlled trials (RCTs) involving 8039 PE patients met the inclusion criteria.

The study included patients aged 18 years or older and the patients were randomized for dapoxetine 30 mg or dapoxetine 60 mg or placebo administration on-demand (1–3 hours prior to anticipated sexual activity).
Unfortunately, the efficacy and safety of dapoxetine (30 mg and 60 mg on-demand) has never been comprehensively studied in men with PE. Most data derived from clinical studies in men with PE are available. The objective of this study was to not only evaluate the efficacy and safety of dapoxetine when used at either 30 mg or 60 mg as compared with the placebo as an oral on-demand treatment in men with PE in routine clinical practice by performing a meta-analytic synthesis of studies, but also to assess whether there are differences in efficacy and safety for PE treatment using either 30 mg or 60 mg dapoxetine. The electronic and manual searches of PubMed, EMBASE and Cochrane Central Register of Controlled Trials (Cochrane Library) databases resulted in 106 references, of which 88 were clearly not relevant to our study. Of the remaining 18 references, 11 were excluded after reading the full text. The basic characteristics of the included studies are summarized in Table 1.
Three of the RCTs selected9,12,13 evaluating dapoxetine versus placebo for PE reported IELT as the primary outcome.
She stimulates him by manipulating his penis first close to and then with friction against her vulval area. Each time he senses excessive excitement, she applies the squeeze and stops all stimulation until he calms down enough for the process to be repeated. Finally, coitus may be attempted, with the female partner in the superior position so that she may withdraw immediately and again apply a squeeze to remove the male partner’s urge to climax. Most couples find this technique to be highly successful. It can also help the female partner to be more aroused and can shorten her time to climax because it constitutes a form of extended foreplay in many cases.
If the male is relatively young and can achieve another erection within a few minutes after a premature ejaculation, he may find that he is much less likely to experience a premature ejaculation the second time. The interval for achieving a second climax often includes a much longer period of latency, and the male can usually exert better control in this setting. Accordingly, some therapists advise young men to masturbate (or have their partner stimulate them rapidly to climax) 1-2 hours before sexual relations are planned. In an older man, such a strategy may be less effective, because the older man may have difficulty achieving a second erection after his first rapid sexual release. If this occurs, it can damage his confidence and may result in secondary impotence.
Kilinc et al reported that moderate physical activity longer than 30 min at least 5 times a week leads to ejaculation delay in patients with premature ejaculation. In their study, 35 patients were treated with dapoxetine, 30 mg on demand; 35 performed moderate physical activities; and 35 performed minimal physical activity. [59] Pastore et al reported long-term benefit from pelvic muscle floor rehabilitation (PFM) in patients with lifelong premature ejaculation. The 154 participants in this retrospective study entered a 12-week program of PFM rehabilitation, including physio-kinesiotherapy treatment, electrostimulation, and biofeedback, with three sessions per week, with 20 min for each component completed at each session. Of the 122 participants who completed PFM rehabilitation, 111 gained control of their ejaculation reflex. Our pooled analysis showed that PE in patients in the dapoxetine group showed a significant improvement in IELT when compared to patients in the placebo group (mean difference [MD] = 1.39; 95% confidence interval [95% CI] = 1.24–1.55; P < 0.00001).
Among these studies, we carried out a subgroup analysis based on PE patients treated with dapoxetine 30 mg and 60 mg on-demand oral administration. A statistically significant difference was found in the subgroup treated with 30 mg dapoxetine compared with the placebo-treated group (MD = 1.16; 95% CI = 0.94–1.38; P < 0.00001).
The subgroup analysis of the dapoxetine group treated with 60 mg compared with placebo also reporting IELT also revealed a statistically significant difference in patient response (MD = 1.63; 95% CI = 1.41–1.84; P < 0.00001).
In addition, five studies9,12,13,14,15 including a total of 3346 patients, we pooled to compare IELT; patients were divided into two groups treated with either 60 mg or 30 mg dapoxetine.
We aimed to compare the intravaginal ejaculatory latency time (IELT), patient-reported global impression of change (PGIC) and adverse effect (AE) incidence associated with the use of dapoxetine (30 mg and 60 mg) versus placebo and evaluate the differences in administering 60 mg versus 30 mg as on-demand medical oral therapy for the treatment of PE via a literature review and meta-analysis. Relevant randomized controlled trials (RCTs) were identified from PubMed, EMBASE and Cochrane Central Register of Controlled Trials (Cochrane Library) databases. Ultimately, a total of seven RCTs with 8039 patients were included. Our meta-analysis demonstrated that dapoxetine (in the 30 mg and 60 mg subgroup) resulted in significantly higher IELT, PGIC and AE incidence relative to the placebo, with higher proportions observed for 60 mg versus 30 mg of dapoxetine administration. The for sale priligy most common AEs were mild and tolerable.
We conclude that dapoxetine (particularly the 60 mg dosage) may be considered a safe and effective drug for patients with PE. Premature ejaculation (PE) is the most common male sexual dysfunction with a prevalence of between 20% and 40%1,2. Recently, the International Society for Sexual Medicine has proposed the following evidence-based definition: “PE is a male sexual dysfunction characterized by ejaculation that always or nearly always occurs prior to or within about 1 minute of vaginal penetration; inability to delay ejaculation on all or nearly all vaginal penetrations; and negative personal consequences, such as distress, bother, frustration, and/or the avoidance of sexual intimacy”3,4. In addition, PE affects numerous aspects of a man's life, including sexual confidence, interpersonal relationships and the sexual satisfaction of both partners5. The role of PE on the individual and the sexual relationship is very significant.
Thus, it is important to treat patients with PE in order to improve quality of life. At present, treatment of PE includes mainly psychotherapy, drug therapy and surgical treatment6. Drug therapy is not only likely to be the most receptive approach for patients, but it is also the most commonly used method. Selective serotonin reuptake inhibitors (SSRIs) have become the most widely used medicine in the world7. Dapoxetine hydrochloride, belonging to the class of SSRIs, was the first drug originally approved for the on-demand treatment of men with PE by seven European countries in 20088.
