Study summary

This randomized controlled trial evaluated the comparative effectiveness and safety of four pharmacological treatments-Citalopram 20mg, Silodosin 4 mg, Dapoxetine 30 mg on demand, and Dapoxetine 30 mg daily-in men with premature ejaculation (PE). A total of 400 male patients were enrolled at Beni-Suef University Hospital and randomly assigned to one of four treatment groups (n=100). The primary outcome was the change in intravaginal ejaculatory latency time (IVELT), while secondary outcomes included ejaculatory control and sexual satisfaction, assessed using the Premature Ejaculation Profile Questionnaire (PEPQ). Side effects were also evaluated using multivariate regression analysis.

Inclusion criteria

  • Diagnosis of PE according to Premature Ejaculation Profile Questionnaire (PEPQ) and the , 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)
  • PEPQ score ≥11.

    • Age ≥ 20 years.
    • In a stable, monogamous, heterosexual relationship for at least 3 months.
    • Signed indicating willingness to participate.

Exclusion criteria

Exclusion Criteria:

  • Use of PE medications in the preceding 4 weeks.
  • Use of hormonal supplements.
  • Patients with erectile dysfunction diagnosed by International Index of Erectile Function.
  • History of psychiatric or significant physical disorders (in either patient or partner).
  • Use of antidepressants, local anesthetic sprays, intracavernosal injections, or psychotherapy within 4 weeks.
  • Alcohol or substance abuse.
  • Documented hypotension.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. ● Intravaginal Ejaculatory Latency Time: Minimum Value: 0 seconds Maximum Value: No fixed maximum, but usually recorded up to ~30 minutes in clinical studies Interpretation: Lower IELT values indicate worse outcomes, as they reflect shorter ejaculator

    Time frame: 3 months

Secondary outcomes

  1. ● Premature Ejaculation Profile Questionnaire (PEPQ): Each item is scored from 1 to 5, and the total score ranges from 4 to 20. Minimum Value: 4 Maximum Value: 20 Higher scores indicate better outcomes

    Time frame: 3 MONTHS

  2. Adverse events

    ● Side effects: Adverse effects were evaluated in terms of occurrence

    Time frame: 3 months

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2024 to primary completion in Jan 2025, 7 months.

Of 54 non-industry phase 4 interventional studies under Premature Birth, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 60. This study's 7 months is below that.

Counting every sponsor, half of 54 studies reached it within 25 months; a quarter within 13 and three quarters within 60.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 8, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
