Effect of Serum Vitamin B12 Levels on Premature Ejaculation.

To assess the impact of vitamin B12 levels in the failure of the dapoxetine used in premature ejaculation (PE) treatment. Experimental study. Place and Duration of the Study: Andrology Clinic, between May and December 2020. Patients with premature ejaculation complaints completed the Premature Ejaculation Diagnostic Tool (PEDT) questionnaire. Patients were also asked to fill in the Premature Ejaculation Profile (PEP) surveys. Intravaginal ejaculation latency time (IELT) were recorded based on the estimates of patients. Serum vitamin B12 levels were evaluated based on blood samples. All patients were advised to use dapoxetine 30 mg, 1-3 hours prior to intercourse. After four weeks, patients were asked to complete the PEP questionnaire again. IELT times were recorded. A total of 62 patients were included in the study. A total of 39 patients (62.90%) were satisfied with the treatment of the dapoxetine. In comparison to patients who benefited from dapoxetine treatment and those who did not, vitamin B12 levels of patients who did not benefit from dapoxetine were found to be significantly lower (p=0.005). Vitamin B12 deficiency can reduce the effectiveness of dapoxetine treatment in patients with PE. It is important to evaluate serum vitamin B12 levels for the evaluation of patients with PE.

PS-05-004 Discontinuation of dapoxetine treatment in patients with premature ejaculation: A 2-year prospective observational study

Although dapoxetine is the only oral pharmacological agent approved for the treatment of premature ejaculation (PE) and is very effective, its discontinuation rate is high compared to PDE5 inhibitors in patients with erectile dysfunction (ED). This study assessed the discontinuation rate of dapoxetine treatment in patients with PE and the reasons for discontinuation a clinical setting. The study enrolled 182 consecutive patients (mean age 38.2 (range 19–63) years). The PE type (life-long or acquired), self-estimated intravaginal ejaculation latency time (IELT), International Index of Erectile Function-Erectile Function Domain (IIEF-EF) questionnaire, and medical history were checked in all patients. The patients were evaluated 1, 3, 6, 12, and 24 months after initiating therapy regarding the treatment status and the reasons for treatment discontinuation in the case of discontinuation. We compared the discontinuation rates with various parameters and the time interval. Of the patients, 9.9% were continuing treatment after 2 years. The discontinuation rate at 1, 3, 6, 12, and 24 months was 26.4, 35.2, 17.6, 8.2, and 2.7%, respectively. Cumulatively, 79.1% of the patients discontinued the treatment within 6 months. After 12 months, however, the discontinuation rate dropped sharply. The reasons for discontinuation were cost (29.9%), disappointment that PE is not a curable disease and dapoxetine was needed whenever he had sex (25%), side effects (11.6%), low efficacy (9.8%), to seek other treatment options (5.5%), and unknown (18.3%). Patients with acquired PE (vs. life-long), IELT >2 min before treatment, older than 50 years, taking PDE-5 inhibitors, and IIEF-EF <26 tended to discontinue early and had high drop-out rates.

AB087. Discontinuation of dapoxetine treatment in patients with premature ejaculation: a 2-year prospective observational study

BackgroundAlthough dapoxetine is the only oral pharmacological agent approved for the treatment of premature ejaculation (PE), and is very effective, the discontinuation rate is high. We assessed the discontinuation rate in patients with PE, and the reasons for discontinuation, in real-world practice.MethodsA total of 182 consecutive patients [mean age 38.2 (range, 19–63) years] were enrolled. The type of PE (lifelong or acquired), the self-estimated intravaginal ejaculation latency time (IELT), and medical history were evaluated in all patients, who also completed the International Index of Erectile Function-Erectile Function Domain (IIEF-EFD) questionnaire. Visits were scheduled 1, 3, 6, 12, and 24 months after initiation of therapy; we checked treatment status and the reasons for discontinuation in those who did in fact discontinue. We compared the relationships of discontinuation rates with various parameters and the time to discontinuation after treatment commencement.ResultsOf all patients, 9.9% continued treatment to 2 years. The discontinuation rates at 1, 3, 6, 12, and 24 months were 26.4%, 35.2%, 17.6%, 8.2%, and 2.7%, respectively. Cumulatively, 79.1% of all patients discontinued treatment within 6 months. After 12 months, however, the discontinuation rate fell sharply. The reasons for discontinuation were cost (29.9%), disappointment that PE was not curable and that dapoxetine was required every time sexual intercourse was contemplated (25%), side effects (11.6%), perceived poor efficacy (9.8%), a search for other treatment options (5.5%), and unknown (18.3%). Patients with acquired PE (compared to lifelong PE), with IELT >2 min prior to treatment, on PDE-5 inhibitors, and with IIEF-EF scores <26 tended to discontinue early and thus exhibited high drop-out rates.ConclusionsOnly 9.9% of patients continued treatment to 24 months; 79.1% discontinued within 6 months. The main reasons for discontinuation were the cost and disappointment that treatment was required every time adequate sexual function was required, followed by side effects and perceived poor efficacy. These results indicate that a better strategy is required to manage PE patients.

Discontinuation of Dapoxetine Treatment in Patients With Premature Ejaculation: A 2-Year Prospective Observational Study.

IntroductionAlthough dapoxetine is the only oral pharmacologic agent approved for the treatment of premature ejaculation (PE) and is very effective, the discontinuation rate is high.AimTo assess the discontinuation rate of patients with PE and the reasons for discontinuation in real-world practice.MethodsIn total, 182 consecutive patients were enrolled. Type of PE, self-estimated intravaginal ejaculation latency time, and medical history were evaluated in all patients who also completed the erectile function domain of the International Index of Erectile Function (IIEF). Visits were scheduled 1, 3, 6, 12, and 24 months after initiation of therapy; treatment status and the reasons for discontinuation in those who did discontinue were checked. The relations of discontinuation rates were compared with various parameters and the time to discontinuation after treatment commencement.ResultsOf all patients, 9.9% continued treatment to 2 years. The cumulative discontinuation rates at 1, 3, 6, 12, and 24 months were 26.4%, 61.6%, 79.1%, 87.3%, and 90.1%, respectively. Moreover, 79.1% of all patients discontinued treatment within 6 months. After 12 months, the discontinuation rate decreased sharply. The reasons for discontinuation were cost (29.9%), disappointment that PE was not curable and that dapoxetine was required every time sexual intercourse was contemplated (25%), side effects (11.6%), perceived poor efficacy (9.8%), a search for other treatment options (5.5%), and unknown (18.3%). Patients with acquired PE (vs lifelong PE), with intravaginal ejaculation latency time longer than 2 minutes before treatment, on phosphodiesterase type 5 inhibitors, and with IIEF erectile function scores lower than 26 tended to discontinue early and thus exhibited high dropout rates.ConclusionThe treatment discontinuation rate of dapoxetine was very high. The main reasons for discontinuation were the cost and disappointment that treatment was required every time adequate sexual function was required.Park HJ, Park NC, Kim TN, et al.

Discontinuation of Dapoxetine Treatment in Patients with Premature Ejaculation: A 2-Year Prospective Observational Study

Objective: Although dapoxetine is the only oral agent approved for premature ejaculation (PE) and is very effective, its discontinuation rate is high compared to PDE5 inhibitors for ED treatment. We assessed discontinuation rate of dapoxetine in PE and the reasons for discontinuation. Design and Method: The study enrolled 182 patients (mean age 38.2). The PE type (life-long or acquired), self-estimated intravaginal ejaculation latency time (IELT), IIEF-EF questionnaire, and medical history were checked in all patients. The patients were evaluated 1, 3, 6, 12, and 24 months after initiating therapy regarding the treatment status and the reasons for treatment discontinuation. Results: Of the patients, 9.9% were still in treatment after 2 years. The discontinuation rates at 1, 3, 6, 12, and 24 months were 26.4, 35.2, 17.6, 8.2, and 2.7%, respectively. Cumulatively, 79.1% of the patients discontinued the treatment within 6 months. After 12 months, however, the discontinuation rate dropped sharply. The reasons for discontinuation were cost (29.9%), disappointment that PE is not a curable disease and dapoxetine was needed whenever he had sex (25%), side effects (11.6%), low efficacy (9.8%), to seek other treatment options (5.5%), and unknown (18.3%). Patients with acquired PE (vs. life-long), IELT &gt;2 min before treatment, older than 50 years, taking PDE-5 inhibitors, and IIEF-EF &lt;26 tended to discontinue early and had high drop-out rates. Conclusions: Only 9.9% patients continued treatment after 24 months, while 79.1% discontinued within 6 months. The main reasons for discontinuation were not related to its side effects or low efficacy.

Dapoxetine Treatment in Patients With Lifelong Premature Ejaculation: The Reasons of a “Waterloo”

To assess both the acceptance and the discontinuation rates from dapoxetine, the first oral pharmacological agent indicated for the treatment of premature ejaculation (PE). One hundred twenty consecutive potent patients (mean age 40.3 years; range 18-63 years) seeking medical treatment for lifelong PE were enrolled in a prospective phase II study. Moreover, they were assessed regarding detailed medical and sexual history, intravaginal ejaculatory latency time (IELT), International Index of Erectile Function (IIEF), and complete physical examination. The patients received a dapoxetine prescription (30 mg on demand) and unresponded cases received increased dose (60 mg after 3 months). The patients were evaluated at 1, 3, 6, and 12 months, and requested to complete a multiple-choice global assessment questionnaire regarding specific reasons for eventual therapy discontinuation. Twenty-four of the patients (20%) decided not to start dapoxetine. Fear of using a "drug" was the most frequently reported reason for treatment nonacceptance (50%) and the cost of treatment was the reason for 25% of the patients. Ninety-six patients (80%) started the therapy. Twenty-six percent dropped out after 1 month, 42.7% dropped out after 3 months, 18.7% dropped out at 6 months, 2% dropped out at 12 months, and 10.4% are continuing the therapy after 1 year. The main reasons were effect below expectations 24.4%, costs 22.1%, side effects 19.8%, loss of interest in sex 19.8%, and no efficacy 13.9%. Twenty percent of lifelong PE patients seeking medical treatment for early ejaculation freely decided not to start treatment with dapoxetine, and roughly 90% of the patients who started therapy discontinued after 1 year.
