Dapoxetine for Premature Ejaculation: An Updated Meta-Analysis of Randomized Controlled Trials
Dapoxetine 30 mg (daily) outperformed 30 mg (on demand) in select categories (P = 0.01 for interpersonal difficulty), though not all comparisons reached statistical significance. All treatment arms exceeded the 0.5 SD MCID for IELT and PEPQ.

Median percent change in IELT was highest in the Citalopram group at + 260% (IQR: 197.5–330.5), followed by Dapoxetine 30 mg (daily) at + 220%, Dapoxetine 30 mg (on demand) at + 197%, and Silodosin at + 149.5% All within-group comparisons were statistically significant (P < 0.001). In terms of subjective outcomes (Table 3), all treatment groups showed statistically significant improvements in PEPQ scores (P < 0.001), reflecting enhanced ejaculatory control, sexual satisfaction, and reduced personal distress and interpersonal difficulty. Among the groups, Citalopram resulted in the highest median percentage improvement (300%), followed by Dapoxetine 30 mg (daily) (225%), Dapoxetine 30 mg (on demand) (166.7%), and Silodosin (175%). These findings indicate that Citalopram not only prolonged latency time objectively but also yielded the most favorable patient-reported outcomes, suggesting a greater overall benefit in the psychological and relational aspects of premature ejaculation management. Pairwise analysis post treatment according to PEPQ (Table 4) showed that Citalopram was significantly more effective than Silodosin in all domains (P < 0.001), and superior to both Dapoxetine doses in most comparisons, including interpersonal difficulty (P < 0.01). Responder rates were correspondingly high and exceeding the MCID threshold largely (Table 5).

This study aimed to evaluate the effects of citalopram, dapoxetine, and silodosin in the treatment of premature ejaculation (PE), with a focus on changes in intravaginal ejaculatory latency time (IELT) and the psychological aspects of sexual function, including perceived control, satisfaction, personal distress, and interpersonal difficulty.

Baseline characteristics were comparable across all groups, with no statistically significant differences observed in age, duration of PE, comorbid conditions (diabetes mellitus, hypertension, cardiac disease, hepatic/renal disease), or laboratory parameters (FSH, LH, free testosterone, cholesterol, and triglycerides). These findings suggest that the observed changes in treatment outcomes were independent of these baseline characteristics.

The total sample size in the ANOVA/ANCOVA framework was determined using the noncentral F distribution according to the following relationship: The achieved power is then calculated as: Using f = 0.25, α = 0.05, and 95% power, with four treatment groups and four covariates, the required sample size was confirmed as 400 participants (100 per group). Diagnosis of PE according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-V-TR) [12]. ◦ Persistent or recurrent ejaculation within approximately 1 minute of vaginal penetration (confirmed by stopwatch-measured IELT ≤60 seconds at baseline) ◦ Inability to delay ejaculation during all or nearly all vaginal penetrations ◦ Negative personal consequences (distress, frustration, avoidance of sexual intimacy) Premature Ejaculation Diagnostic Tool (PEDT) score ≥11. ◦ Persistent or recurrent ejaculation within approximately 1 minute of vaginal penetration (confirmed by stopwatch-measured IELT ≤60 seconds at baseline) ◦ Persistent or recurrent ejaculation within approximately 1 minute of vaginal penetration (confirmed by stopwatch-measured IELT ≤60 seconds at baseline) ◦ Inability to delay ejaculation during all or nearly all vaginal penetrations ◦ Inability to delay ejaculation during all or nearly all vaginal penetrations ◦ Negative personal consequences (distress, frustration, avoidance of sexual intimacy) ◦ Negative personal consequences (distress, frustration, avoidance of sexual intimacy) Premature Ejaculation Diagnostic Tool (PEDT) score ≥11.

Use of antidepressants, local anesthetic sprays, intracavernosal injections, or psychotherapy within 4 weeks. Participants were randomly assigned to four equal groups (n = 100 each) using a computer-generated and centralized randomization: Group A: Received Citalopram hydrobromide, starting with 10 mg once daily for 1 week, followed by 20 mg once daily for 10 weeks, and 10 mg daily during the final week (tapered). Group A: Received Citalopram hydrobromide, starting with 10 mg once daily for 1 week, followed by 20 mg once daily for 10 weeks, and 10 mg daily during the final week (tapered). Group B: Received Silodosin 4 mg, administered orally once daily. Group C: Received Dapoxetine hydrochloride 30 mg, taken 2 h before intercourse, on-demand, minimum of 8 times/month for 3 months. This is consistent with other studies in this field, which also found no significant baseline differences across treatment groups [11, 12].

The results demonstrated significant increases in IELT across all treatment groups, with the most substantial improvement observed in the Citalopram group. Increasing IELT represents a considerable improvement in ejaculation latency.
What causes Premature Ejaculation
Group D: Received Dapoxetine hydrochloride 30 mg, administered daily. Comprehensive medical history, including comorbidities (e.g., diabetes, hypertension), medication review for drug interactions, erectile function and prostatitis. Physical examination focused on genitourinary abnormalities (e.g., prostatitis, hypospadias). Lab tests: including FSH, LH, free testosterone, cholesterol, and triglycerides. The assessors of the outcomes were blinded during the study procedures.

Adherence was assessed at each visit by pill count and patient diaries. We assessed clinical meaningfulness using distribution-based MCID thresholds because there is currently no published literature which identifies a clinically significant threshold response to IVELT and PEPQ. Following established methodology, we prespecified 0.5 SD of baseline IVELT and PEPQ as the primary MCID. Intravaginal Ejaculatory Latency Time (IELT): Measured by the partner using a wristwatch (Casio®, Tokyo, Japan), defined as the interval between vaginal penetration and ejaculation. IELT was recorded pre- and post-intervention (after 3 months).

Premature Ejaculation Profile Questionnaire (PEPQ) [13]: Evaluated perceived ejaculatory control, sexual satisfaction, personal distress, and interpersonal difficulty. Each domain was assessed via a single-item, 5-point Likert scale (0–4), with higher scores indicating improved functioning. Side effects: Adverse effects were evaluated in terms of occurrence of nausea, diarrhea, vomiting, headaches, decreased semen volume, retrograde ejaculation, anejaculation, constipation, dizziness, sleep disturbance, and dry mouth. Statistical analysis was performed using SPSS version 26.0 (IBM tadalafil with dapoxetine tablets Corp., Armonk, NY, USA). Continuous variables were expressed as mean ± SD; categorical variables as number and percentage. These results corroborate previous studies indicating that SSRIs like citalopram are highly effective in prolonging ejaculation latency [13, 14].

Between-group comparisons were analyzed using ANOVA with post-hoc Tukey tests. Within-group pre/post comparisons were analyzed using paired t-tests. Categorical variables were compared using χ² or Fisher’s exact test. Significance was set at p < 0.05. A total of 400 participants were included.

Figure 1 shows the CONSORT flow diagram of the study procedures (Table 1), show Baseline characteristics were comparable across the four groups, with no statistically significant differences in age, duration of the disorder, comorbidities (diabetes mellitus, hypertension, cardiac or hepatic/renal disease), or laboratory data including FSH, LH, free testosterone, cholesterol, and triglycerides. Age ranged from 33.91 ± 8.84 years to 36.21 ± 8.98 years. Comorbid conditions were distributed without significant group differences. In (Table 2) All treatment groups demonstrated a significant increase in IELT following 3 months of therapy. The greatest improvement was observed in the Citalopram group, where IELT increased from 110.4 ± 31.5 s to 391.2 ± 45.9 s. These improvements were observed across all four domains: perceived control, sexual satisfaction, personal distress, and interpersonal difficulty. The Citalopram group demonstrated the highest improvement in patient-reported outcomes.
