However, no valid conclusions from these studies comparing 60 mg versus 30 mg dapoxetine could be obtained since these lacked strong statistical evidence. In this meta-analysis, in order to obtain a reliable and scientifically sound comparison of dapoxetine (30 and 60 mg) versus placebo and dapoxetine 60 mg versus dapoxetine 30 mg as on-demand oral treatment for PE, a precise search strategy was performed to include all relevant RCTs. Therefore, studies of patients with erectile dysfunction18, non-RCTs19 and studies including patients with chronic, daily oral treatment with dapoxetine20,21 were excluded from the analysis of patients with PE. Ultimately, seven RCTs met the inclusion criteria for the present meta-analysis. To our knowledge, this is the most recent systematic review and meta-analysis comparing oral dapoxetine on-demand with placebo and comparing dapoxetine dosages (60 mg versus 30 mg) for the treatment of patients with PE.

2.1 Chemical Structure and Classification

The present meta-analysis for IELT demonstrated that on-demand oral treatment with dapoxetine had an advantage over placebo despite the different dosages (30 mg and 60 mg) used. It demonstrated that on-demand oral dapoxetine was an effective treatment for PE. In addition, our meta-analysis comparing dapoxetine 60 mg with 30 mg on-demand orally proved that there was a statistically significant difference in IELT between the both groups; thus, 60 mg dapoxetine had a longer IELT than 30 mg on-demand for PE. The present findings are in agreement with the results of previous clinical trials that have reported significant improvement in the IELT with the use of dapoxetine9,10,11,12,13,14,15,16,17,18,19,20,21. Mean IELT was also significantly increased in all the studies not included in this meta-analysis.

• Dapoxetine 60 mg is a medication used to treat premature ejaculation in men.
• It is classified as a selective serotonin reuptake inhibitor (SSRI).
• The recommended dose for most men is a 60 mg tablet taken 1-3 hours before intercourse.
• Dapoxetine is fast-acting, typically beginning to work within 30 minutes.
• Possible side effects include nausea, dizziness, headache, and insomnia.
• Dapoxetine 60 mg should be used under medical supervision to avoid interactions.
• It is not intended for daily use but on-demand treatment before sexual activity.
• Patients should avoid alcohol as it can increase side effects and reduce effectiveness.

The present findings are in agreement with the results of previous clinical trials that have reported significant improvement in the IELT with the use of dapoxetine9,10,11,12,13,14,15,16,17,18,19,20,21. Mean IELT was also significantly increased in all the studies not included in this meta-analysis. Mirone et al22 performed non-RCT trials in 2014 that compared dapoxetine 30–60 mg with alternative care/nondapoxetine, the results revealed that dapoxetine for treatment of PE had a longer mean IELT. The integrated analysis from five trials by McMahon et al19 also showed dapoxetine 30 and 60 mg on-demand significantly increased mean IELT compared with placebo (1.9 minutes for placebo, 3.1 and 3.6 minutes for dapoxetine 30 mg and 60 mg, respectively).

Our statistical results and subgroup analysis of PGIC demonstrated that dapoxetine was associated with a major improvement in PGIC. As shown in Figure 5, the overall RR was 2.14 (95% CI = 1.90–2.24) between dapoxetine and placebo, 2.01(95% CI = 1.69–2.38) between the dapoxetine 30 mg subgroup and placebo and 2.26 (95% CI = 1.91–2.67) between the dapoxetine 60 mg subgroup and placebo, respectively. Additionally, the present meta-analysis also demonstrated significant improvement in PGIC with 60 mg over 30 mg dapoxetine on-demand alone. Pryor et al9 thought that the PGIC condition as a study endpoint is informative with respect to men's perception to minor detectable changes in IELT. In other words, there is a positive relationship between the participants' PGIC ratings and mean change in IELT values. The present findings agree with the results of previous clinical trials that reported a similar improvement in PGIC with dapoxetine versus placebo or comparing 60 mg versus 30 mg dapoxetine9,10,11,12,13,16,17,18,19,20,21. This analysis revealed the incidence of total AEs was more frequent with dapoxetine than with placebo and more common with dapoxetine 60 mg than 30 mg.

Rights and permissions

The unique pharmacokinetic characteristics might be the reason why dapoxetine is the on-demand treatment of choice for PE. Safety and efficacy data have demonstrated that dapoxetine use produces acceptable improvement in the IELT and PGIC with on-demand use. Thus, we also believe it is probably better suited as an on-demand treatment option for PE26. Our systematic review and meta-analysis has many drawbacks, the primary one being that this was a heterogeneous trial. In an attempt to reduce the high heterogeneity, we carried out a subgroup analysis among studies involving the drug dosage sildenafil dapoxetine tablets used (30 mg versus 60 mg groups).

Chemical Formula

The heterogeneity was significantly decreased when comparing dapoxetine with placebo in the IELT by subgroup analysis. However, this heterogeneity of data still exists in the PGIC and AEs analyses, which we were unable to improve. We believe this heterogeneity might have resulted in the evaluation of the PGIC value using a 7-point scale (from −3 = much worse to 3 = much better) and AEs that were assessed using a subjective evaluation by individual patients. Additional factors might have been potentially amplified heterogeneity; these include differences in treatment duration, individual differences and mental or physical conditions. Secondly, some of the included studies did not report the outcome measures; hence, the statistical results might be influenced by the statistical parameters used for calculations. However, from a review tadalafil with dapoxetine online of all the studies reported in the literature, AEs of dapoxetine are generally tolerable. In the integrated analysis of the McMahon et al16 study, total AEs occurred in 35.1%, 47.0%, 60.3% subjects with placebo, dapoxetine 30 mg and dapoxetine 60 mg on-demand orally, respectively. In Figure 7, the total number of AEs occurred in 49.1% (2601/5293) and 20.7% (1040/5017) of subjects treated with dapoxetine and placebo, respectively. In Figure 8, the total number of AEs occurring with dapoxetine 60 mg or 30 mg were 58.2% (1421/2441) and 36.6% (907/2476), respectively. The most frequently reported AEs were nausea, dizziness, headache, diarrhea and insomnia22,23. Fortunately, the most common AEs with dapoxetine were mild or moderate in nature and were transient symptoms9,10,11,12,13,15,16,17,18,19,20,21,24,25.

8. Special Populations and Considerations

Additionally, nearly all trials included in this study lacked a clear description of the allocation concealment, but all trials included in this meta-analysis were RCTs, the methods were designed well. Thus, the data from the studies included tadalafil dapoxetine in our meta-analysis were reliable. In summary, our meta-analysis has shown that either 30 mg or 60 mg dapoxetine on-demand orally was associated with a significantly greater increase in mean IELT and PGIC compared placebo. Additionally, 60 mg had a better efficacy than 30 mg dapoxetine on-demand orally. However, the meta-analysis also demonstrated that those treated with dapoxetine (especially 60 mg on-demand orally) reported more AEs than placebo or the dapoxetine 30 mg group.

Quá liều

Nonetheless, the most commonly reported AEs were mild and tolerated. We searched the following databases up to and including June 2014: MEDLINE by PubMed, EMBASE, Cochrane Central Register of Controlled Trials (Cochrane Library). We did not restrict our search to articles published in English and the following search terms were used in conjunction with: dapoxetine, SSRIs and premature ejaculation, sexual dysfunction. We also searched the relevant references of all studies included in the analysis. All retrieval literatures were independently performed by Cao D and HY. The present findings agree with the results of previous clinical trials that reported similar low incidence rates of side effects. Dapoxetine is a short-acting SSRI and doses of 30 mg and 60 mg have been evaluated through our meta-analysis. Peak plasma concentrations of dapoxetine were observed within 1.01–1.27 hours after oral administration24. The elimination half-life time is 1.3–1.4 hours and there appears to be very little accumulation24.

Mirone et al22 performed non-RCT trials in 2014 that compared dapoxetine 30–60 mg with alternative care/nondapoxetine, the results revealed that dapoxetine for treatment of PE had a longer mean IELT. The integrated analysis from five trials by McMahon et al19 also showed dapoxetine 30 and 60 mg on-demand significantly increased mean IELT compared with placebo (1.9 minutes for placebo, 3.1 and 3.6 minutes for dapoxetine 30 mg and 60 mg, respectively).

Additionally, the present meta-analysis also demonstrated significant improvement in PGIC with 60 mg over 30 mg dapoxetine on-demand alone.

Study selection

Pryor et al9 thought that the PGIC condition as a study endpoint is informative with respect to men's perception to minor detectable changes in IELT. In other words, there is a positive relationship between the participants' PGIC ratings and mean change in IELT values. The present findings agree with the results of previous clinical trials that reported a similar improvement in PGIC with dapoxetine versus placebo or comparing 60 mg versus 30 mg dapoxetine9,10,11,12,13,16,17,18,19,20,21. This analysis revealed the incidence of total AEs was more frequent with dapoxetine than with placebo and more common with dapoxetine 60 mg than 30 mg. However, from a review tadalafil with dapoxetine online of all the studies reported in the literature, AEs of dapoxetine are generally tolerable. Dapoxetine undergoes rapid absorption, elimination and dose-dependent pharmacokinetics, which are unaffected by multiple dosing.

Included in the study were all published or unpublished RCTs evaluating dapoxetine interventions for PE. Studies comparing dapoxetine intervention versus placebo or another drug intervention were eligible for this review. All relevant studies were included in this study if they met the following criteria: (1) all patients were older than 18 years; (2) patients were diagnosed with PE; (3) patients were treated with oral dapoxetine on-demand (1–3 hours before sexual activity); (4) data were available for at least one of the predefined outcome measurements. Studies were excluded if (1) patients were diagnosed with mixed sexual dysfunction such as erectile dysfunction plus PE; (2) patients were treated with a fixed-dose orally daily; (3) the data referred to data from an animal study; or (4) studies reported data from non-RCTs or quasi-RCTs. The following variables from each study were recorded independently by two reviewers and cross-checked: first author name, publication year, research design type, total number of patients enrolled, patient age, intervention method, outcome measures.

In addition, the following primary outcome was extracted: IELT, defined as the time from the start of vaginal insertion to the start of intravaginal ejaculation and measured using the stopwatch. The secondary outcomes were as follows: PGIC, also called the clinical global impression of change (CGIC or CGI) in some studies, defined as a validated tool used to measure overall perceived change in patients with better and much better results after treatment (i.e., “Compared to the start of the study, would you describe your PE problem as much worse, worse, slightly worse, no change, slightly better, better, or much better?27”) and AEs, defined as potential symptoms related to dapoxetine discontinuation syndrome such as nausea, diarrhea, insomnia, headache, dizziness, erectile dysfunction, fatigue. The methodological quality of the included studies was measured independently by two reviewers using the Cochrane Handbook for Systematic Reviews of Interventions28. The main evaluation items included: (1) random sequence generation (selection bias), (2) allocation concealment (selection bias), (3) blinding of participants (performance bias), (4) blinding of outcome assessment (detection bias), (5) incomplete outcome data (attrition bias), (6) selective reporting (reporting bias) and (7) other bias. These criteria for a judgment of low, high, or unclear risk of bias for each item were used to describe the bias. The unique pharmacokinetic characteristics might be the reason why dapoxetine is the on-demand treatment of choice for PE. Safety and efficacy data have demonstrated that dapoxetine use produces acceptable improvement in the IELT and PGIC with on-demand use.

• Prescription only in most countries; requires medical evaluation before initiation.
• A baseline assessment of blood pressure and cardiovascular risk is recommended.
• Regular follow-up every 3-6 months to monitor efficacy and side effect profile.

Thus, we also believe it is probably better suited as an on-demand treatment option for PE26. Our systematic review and meta-analysis has many drawbacks, the primary one being that this was a heterogeneous trial. In an attempt to reduce the high heterogeneity, we carried out a subgroup analysis among studies involving the drug dosage sildenafil dapoxetine tablets used (30 mg versus 60 mg groups). The heterogeneity was significantly decreased when comparing dapoxetine with placebo in the IELT by subgroup analysis.

We believe this heterogeneity might have resulted in the evaluation of the PGIC value using a 7-point scale (from −3 = much worse to 3 = much better) and AEs that were assessed using a subjective evaluation by individual patients.

Common Side Effects	Incidence Rate	Severity	Management Tips
Nausea	10-15%	Mild	Take with food
Dizziness	8-12%	Mild to Moderate	Avoid operating machinery
Headache	5-10%	Mild	Hydration, pain relief if needed
Insomnia	4-7%	Mild	Maintain a regular sleep routine

Additional factors might have been potentially amplified heterogeneity; these include differences in treatment duration, individual differences and mental or physical conditions. Secondly, some of the included studies did not report the outcome measures; hence, the statistical results might be influenced by the statistical parameters used for calculations. Additionally, nearly all trials included in this study lacked a clear description of the allocation concealment, but all trials included in this meta-analysis were RCTs, the methods were designed well. Thus, the data from the studies included tadalafil dapoxetine in our meta-analysis were reliable.

• Dapoxetine 60 mg is designed to be taken on an as-needed basis.
• Using Dapoxetine can significantly improve sexual satisfaction for some men.
• Always read the patient information leaflet provided with the medication.
• The medication is not suitable for women or individuals under 18 years old.
• Keep track of any side effects experienced and report them to your doctor.
• Do not combine Dapoxetine with other SSRIs or monoamine oxidase inhibitors.
• The effectiveness varies; some men may experience better control than others.
• Avoid driving or operating heavy machinery after taking Dapoxetine if feeling dizzy.

In summary, our meta-analysis has shown that either 30 mg or 60 mg dapoxetine on-demand orally was associated with a significantly greater increase in mean IELT and PGIC compared placebo. Additionally, 60 mg had a better efficacy than 30 mg dapoxetine on-demand orally. However, the meta-analysis also demonstrated that those treated with dapoxetine (especially 60 mg on-demand orally) reported more AEs than placebo or the dapoxetine 30 mg group.

6. Real-World Applications and Clinical Efficacy

In the integrated analysis of the McMahon et al16 study, total AEs occurred in 35.1%, 47.0%, 60.3% subjects with placebo, dapoxetine 30 mg and dapoxetine 60 mg on-demand orally, respectively. In Figure 7, the total number of AEs occurred in 49.1% (2601/5293) and 20.7% (1040/5017) of subjects treated with dapoxetine and placebo, respectively.
