The study included 60 patients diagnosed with ED with mean (SD) baseline scores of 2.2 (1.4) min for IELT and 9.5 (3.7) for the IIEF-5 and at the endpoint was 3.4 (1.9) min and 16.1 (4.7) for IELT and the IIEF-5, respectively.
Can ED Medications Boost Confidence and Sexual Stamina?
PE co-exists with ED in ~30% of patients, mainly secondary PE. However, the specific phenotype of ED-PE men has never been systematically investigated. The five-item version of the International Index of Erectile Function (IIEF-5) questionnaire and intravaginal ELT (IELT) is used to evaluate ED and PE, respectively. The IELT has higher sensitivity and specificity for the evaluation of PE [Citation9]. There are many modalities for PE treatment, the most commonly used are behavioural and pharmacological therapy, but behavioural therapy is inefficient for many couples.
Information to gather in advance
Although many drugs are used for PE, serotonin reuptake inhibitors are the most common drugs used in PE. Other medications like topical anaesthesia or opioid agonists, like tramadol, are less commonly used [Citation10]. Tadalafil with once-daily (OAD) and on-demand [pro re nata (PRN)] dose regimens is sufficient for treating ED. Other studies reported that the tadalafil OAD dose regimen is better, and more sexual satisfaction occurred than PRN [Citation11,Citation12]. Tadalafil, which is commonly used in the treatment of ED, has been recently investigated in some studies for treating PE, and most of these studies reported a significant improvement [Citation13–15].
What to do in case of overdose
There were no data in the literature about long-term follow-up results of tadalafil on the improvement of PE. The present study evaluated the efficacy of daily 5-mg tadalafil treatment vs placebo for 3 months on the erectile function (assessed using the IIEF-5) and ejaculation time (IELT) in patients with ED and PE. In addition, we investigated whether there was a significant improvement in the IIEF-5 and IELT after the stoppage of tadalafil for a long time. A prospective, single-blind, randomised study comparing the safety and efficacy of 5-mg tadalafil continuous daily dosing for 3 months compared with placebo for ED with PE and assessment of persistence of improvement after 2 years from the cessation of tadalafil. This study was conducted on 160 patients attending the urology outpatient clinic, Benha University Hospital, and Al-Azhar University Hospital from April 2018 to April 2019, including men aged 18–65 years who had ED and lifelong PE for the last 6 months of a continuous marriage relationship. Also, tadalafil increased the IELT in all three ED groups (severe, moderate, and mild ED groups).

In addition, there was a statistically significant difference between the pre- and post-treatment values of IELT variables (P < 0.01) in all groups.
| Treatment | Onset of Action | Duration of Effect | Effectiveness | Side Effects |
|---|---|---|---|---|
| Tadalafil | 30-60 mins | Up to 36 hours | Moderate | Headache, flushing |
| SSRIs (e.g., dapoxetine) | 1-3 hours | Short-term | High | Nausea, dizziness |
| Topical anesthetics | Minutes | Localized effect | Varies | Numbness, irritation |
Still, there was no statistically significant difference between the ED groups in terms of IELT, and these results were comparable with our study.

We excluded from our study patients with a neurogenic disorder, parkinsonism, diabetes mellitus, active Urinary tract infection (UTI), chronic prostatitis, chronic renal failure, Peyronie’s disease, and endocrine disorders, including low testosterone, hyperprolactinaemia, and thyroid dysfunction, patients taking medications for PE and drugs affecting erectile function. Written informed consent was obtained from all patients enrolled in this study, which the local ethics committee approved. The sample size was calculated using the EPI info 2000 statistical package (Centers for Disease Control and Prevention (CDC), Atlanta, GA, USA). The null hypothesis of the study was that tadalafil has no treatment effect relative to placebo. A statistical significance at P < 0.05 was required for the two co-primary endpoints (IIEF-5, IELF) to reject the null hypothesis, and a sample size of 160 patients (80 placebo and 80 tadalafil) was calculated to give 90% power to detect a significant treatment effect.
Stomach acid drugs
Patients were subdivided into two equal groups and randomised using the secure envelope method. Group I included 80 patients treated with a daily 5-mg tadalafil oral tablet for 3 months, and Group II included 80 patients treated with a placebo for the same period. The tadalafil group were followed up for 2 years after cessation tadalafil weekend pill of tadalafil, but five patients were lost during follow-up, and so 75 patients were assessed at the end of 2 years. Full medical and sexual history was taken with the history of current medications, a complete physical and genital examination was performed, and all patients were evaluated using the IIEF-5 to evaluate ED and IELT for PE [Citation16] before and after treatment and at the end of the 2-year follow up. The IIEF is a multidimensional validated questionnaire including 15 questions in the five domains of sexual function (erectile and orgasmic functions, sexual desire, satisfaction with intercourse, and overall sexual satisfaction).
Side effect details
More recently, to simplify the IIEF, an abridged five-items version the IIEF-5 has been used as a diagnostic tool for ED and evaluation of treatment. It consists of only five questions, and each IIEF-5 item is scored on a 5-point ordinal scale where lower values represent an impaired sexual function. According to this scale, ED is classified into three grades based on IIEF-5 scores: severe ED (score: 1–7), moderate ED (8–11), and mild ED (12–21) [Citation17]. The IELT was defined as the time from intravaginal intromission to intravaginal ejaculation. Female partners were provided with a stopwatch and instructions on how to record and measure the IELT. Also, our present results agree with Salonia et al.
| Satisfaction Level | Percentage | Sample Size | Comments |
|---|---|---|---|
| Very satisfied | 45% | 150 men | Noted improved control |
| Satisfied | 30% | 150 men | Moderate improvement |
| Dissatisfied | 25% | 150 men | No significant effect |
[Citation22] who reported a significant improvement in IELT and overall sexual satisfaction and decreased stress.
- Tadalafil is sometimes used off-label for treating premature ejaculation.
- It works by relaxing muscles and increasing blood flow.
- Tadalafil may delay ejaculation by altering sensation response.
- Consult a doctor before using tadalafil for PE treatment.
- Dosage varies; typically lower doses are safer for PE.
- Tadalafil is not officially approved for premature ejaculation.
Our present findings disagree with the results of McMahon et al.
Understanding Premature Ejaculation: An Overview
It can be used as an integrated measurement of the partners, and that it was a simple and objective screening indicator for diagnosing self-reporting PE [Citation18]. The collected data were revised, organised, tabulated, and statistically analysed using the Statistical Package for the Social Sciences (SPSS®) version 25.0 (IBM Corp., Armonk, NY, USA). Data are presented as the mean ± standard deviation (SD); Continuous variables in comparable groups were compared by the Student’s t-test (two-tailed). In the intention-to-treat (ITT) analysis, all randomised patients were included in their original group irrespective of their compliance with treatment or loss to follow-up. Patients who were lost to follow-up were considered as a failure to treat.
Cialis and herbs and supplements
The level of significance was accepted for P < 0.05. Both groups were comparable for age, weight, and height (). At the end of 3 months, the mean (SD) IELT in Group I showed a highly significant improvement from 37 (11.24) to 120.5 (47.37) s (P < 0.001). While in Group II, the mean (SD) IELT showed no significant improvement from baseline at 35.98 (10.8) to endpoint at 39.43 (13.6) s (P > 0.05). For the IIEF-5, there tadalafil 2.5 mg was a highly significant improvement from a mean (SD) IIEF-5 score of 13.2 (4.2) at baseline to 20.45 (4.5) at endpoint in Group I (P < 0.001), while there was no statistically significant difference in Group II from baseline at 13.12 (4.11) to 15 (4.84) at endpoint (P > 0.05; ).
Dosage for erectile dysfunction (ED)
For the IIEF-5 scores, the patients with ED were divided into three grades as severe ED (score: 1–7), moderate ED (8–11), and mild ED (12–21). All grades of ED showed a statistically significant difference in IELT in Group I (P < 0.01) vs placebo (Group II). However, there was no significant difference between the grades of ED from baseline to endpoint (P = 0. At the end of the 2-year follow-up, after the cessation of tadalafil, there was a significant improvement in IELT and IIEF-5 form baseline [mean (SD) 37 (11.24) s and 13.2 (4.2), respectively] to endpoint [mean (SD) 98 (18.3) s and 19.1 (2.3), respectively]. However, the IIEF-5 and IELT values decreased slightly compared with the previous values after 3 months of treatment (). [Citation23] who performed a well-designed study to assess the efficacy of sildenafil in men with PE compared to placebo; they found increased overall sexual satisfaction with improved control over ejaculation but without a significant improvement in IELT.
| Contraindication | Reason | Alternative Options |
|---|---|---|
| Nitrate medication use | Risk of severe hypotension | Use other PE treatments |
| Severe cardiovascular disease | Increased risk of adverse events | Non-pharmacologic methods |
| Allergy to tadalafil | Hypersensitivity | Avoid use, consult doctor |
| Liver impairment | Altered drug metabolism | Dose adjustment or alternative |

What Does ‘Low-Dose’ Mean?
The common side-effects were headache in 13 patients (16.25%), lower back pain in 11 (13.75%), dyspepsia in eight (10%), gastro-oesophageal reflux in four (5.0%), and myalgia in three (3.3%). Most of the side-effects disappeared spontaneously over time. The relationship between ED and PE was hypothesised by Jannini et al. [Citation19], as he declared a continuous circle between both PE and ED as the trial to delay ejaculation decreases stimulation and produces ED. The attempt to attain an erection by constant repeated stimulation ends in rapid ejaculation and stress with frustration.
Take as directed
In this scenario, PE occurs secondary to increased sexual arousal to attain erection with anxiety that increases sympathetic stimulation and produces PE [Citation19]. Our present study investigated the effect of daily 5-mg tadalafil on ED and PE after 3 months of medical treatment. It showed a significant improvement in erectile function and overall sexual satisfaction with significant improvement in IIEF-5 scores and IELT compared to placebo. In addition, all ED grades (mild, moderate, and severe) showed a statistically significant improvement in IELT from before to after treatment. However, tadalafil pills it was not statistically significant between the grades.
How long do the effects of tadalafil last?
The first study to assess the effect of 5-mg tadalafil daily on PE was done by Ozcan et al. They found a significant improvement in IELT in patients with lifelong PE. These results comply with our present results that showed improved in IELT up to 2.3 min. In a retrospective study, Karabakan et al. [Citation21] found that 5-mg tadalafil alone for 3 months significantly improved all measured parameters (all P < 0.001). [Citation24] to assess the effect of 20-mg tadalafil alone or with fluoxetine in PE revealed a better improvement in combined tadalafil and fluoxetine than each drug alone.
