Abstract
This study evaluated the bioequivalence of the newly developed dapoxetine hydrochloride tablet relative to the marketed reference product by comparing their pharmacokinetic profiles under fasted and fed conditions. A total of 60 healthy Chinese male subjects participated in a single-center, 2-period, 2-sequence, randomized, open-label, self-crossover study with a washout period of 14 days, 30 in the fasted group and 30 in the fed group. Following a single 30-mg oral dose of the test or reference dapoxetine formulation, blood samples were collected before dosing to 72 hours after dosing. Liquid chromatography-tandem mass spectrometry was performed to measure plasma concentration of dapoxetine and determine pharmacokinetic parameters through noncompartmental analysis. The vital signs and adverse events were also monitored during the study. The 90% confidence intervals of the geometric mean ratios for maximum plasma concentration, area under the plasma concentration-time curve from time 0 to the last concentration time, and area under the plasma concentration-time curve from time 0 extrapolated to infinity of the 2 dapoxetine formulations completely fell within the regulatory criteria for bioequivalence of 80%-125%. In addition, both dapoxetine hydrochloride formulations were generally well tolerated. The generic dapoxetine hydrochloride tablet was bioequivalent to the marketed reference product in healthy Chinese men with no discernible safety differences.

Abstract
PURPOSE Adverse effects of selective serotonin reuptake inhibitors (SSRIs) on sexual function have been an important area of research for many years. However, the duration of SSRI-associated sexual adverse effects, and their possible persistence after treatment discontinuation, is still uncertain. The aims of the current systematic review were first to identify existing evidence of sexual dysfunction following SSRI discontinuation, and to provide an account of reported symptoms and proposed treatment options; and second, to establish whether current literature allows accurate estimates of the prevalence of such sexual dysfunction. METHODS A systematic review was conducted on PubMed, Embase, and Google Scholar; papers with clinical data regarding patients with persistent sexual dysfunction after SSRI treatment suspension were included. RESULTS Overall, two retrospective interventional studies, six observational studies and 11 case reports were judged eligible for inclusion. It was not possible to determine reliable estimates of prevalence. Similarly, a cause-effect relationship between SSRI exposure and persistent sexual impairment could not be ascertained. Nonetheless, the potential for continued sexual disturbances despite discontinuation could not be entirely ruled out. CONCLUSIONS There is a need to investigate a possible dose-response relationship between SSRI exposure and persistent sexual adverse effects. Treatment options for persistent dysfunctions remain limited, but novel therapeutic approaches may be required in order to address an otherwise neglected need for sexual well-being.

Abstract
BACKGROUND Lifelong premature ejaculation (LPE) is a rare sexual condition believed to be caused by genetic neurobiological disorders. In the field of LPE, 2 main types of research have been conducted: direct genetic research and pharmacotherapeutic interference of neurotransmitter systems that can relieve the symptoms of LPE in male patients. OBJECTIVE We aim to provide an overview of studies on neurotransmitter systems as the pathophysiological cause of LPE by investigating direct genetic research or pharmacotherapeutic interference that relieves the main symptom of LPE in male patients. METHODS This scoping review will use the PRISMA-ScR tool (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews). In addition, this study will use a peer-reviewed search strategy. Systematic searches will be conducted using 5 scientific databases (Cochrane Database of Systematic Reviews, PubMed or MEDLINE, Cumulative Index to Nursing and Allied Health Literature [CINAHL], EMBASE, and Epistemonikos). Additionally, pragmatic searches for relevant information in gray literature databases will be performed. Two reviewers will independently include relevant studies in a 2-stage selection strategy. Finally, data will be extracted from the studies and charted to summarize relevant study characteristics and key findings. RESULTS As of July 2022, we completed the preliminary searches according to the PRESS 2015 guidelines and started to determine the final search terms that we will use in all selected 5 scientific databases. CONCLUSIONS This scoping review protocol is the first to focus on neurotransmitter pathways in LPE by combining the results from the genetic and pharmacotherapy studies. The results could help identify potential research gaps or target candidate proteins and neurotransmitter pathways in LPE for further genetic research.

Abstract
OBJECTIVES The Post-University Interdisciplinary Association of Sexology (AIUS) has brought together a panel of experts to develop French recommendations for the management of premature ejaculation. METHODS Systematic review of the literature between 01/1995 and 02/2022. Use of the clinical practice guidelines (CPR) method. RESULTS We recommend giving all patients with PE psychosexological counseling, and whenever possible combining pharmacotherapies and sexually-focused cognitive-behavioral therapies, involving the partner in the treatment process. Other sexological approaches could be useful. We recommend the use of dapoxetine as first-line, on-demand oral therapy for primary and acquired PE. We recommend the use of lidocaine 150mg/mL/prilocaine 50mg/mL spray as local treatment for primary PE. We suggest the combination of dapoxetine and lidocaine/prilocaine in patients insufficiently improved by monotherapy. In patients who have not responded to treatments with marketing authorisation, we suggest using an off-label SSRI, preferably paroxetine, in the absence of a contraindication. We recommend treating ED before PE in patients with both symptoms. We do not recommend using α-1 blockers or tramadol in patients with PE. We do not recommend routine posthectomy or penile frenulum surgery for PE. CONCLUSION These recommendations should contribute to improving the management of PE.

A novel on-demand therapy for lifelong premature ejaculation using a miniature transperineal electrical stimulator-the vPatch: an as-treated analysis. J Sex Med 2023; 20:22-29. [PMID: 36897239 DOI: 10.1093/jsxmed/qdac012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 10/04/2022] [Accepted: 10/09/2022] [Indexed: 01/14/2023]
Abstract
BACKGROUND While premature ejaculation (PE) is a common and disturbing sexual dysfunction in men, current available treatment modalities have limited efficacy and low treatment adherence. AIM To assess the feasibility, safety, and efficacy of the vPatch, a miniaturized on-demand perineal transcutaneous electrical stimulation device for treating PE. METHODS This prospective bicenter international first-in-human clinical study consisted of 2 arms, was sham controlled, and had a randomized double-blind design. In terms of statistical power calculation, 59 patients aged 21 to 56 years (mean ± SD, 39.8 ± 9.28) with lifelong PE were included. During the initial visit, intravaginal ejaculatory latency time (IELT) was measured over a 2-week run-in period. Eligibility was confirmed in visit 2, based on IELT values, medical and sexual history, and patients' individualized sensory and motor activation thresholds during perineal stimulation with the vPatch. Patients were randomized to the active (vPatch) and sham device groups in a 2:1 ratio, respectively. The vPatch device's safety profile was determined by comparing the incidence of treatment-emergent adverse events. During visit 3, IELTs, Clinical Global Impression of Change scores, and Premature Ejaculation Profile questionnaire outcomes were recorded. Primary end points assessed vPatch device efficacy as mean change in geometric mean IELT; each person was compared with himself, with and without the device, and the sham group was compared with the active group. OUTCOMES Outcomes included changes in IELT and Premature Ejaculation Profile before and after treatment, last visit Clinical Global Impression of Change scores, and vPatch safety profile. RESULTS Of 59 patients, 51 completed the study: 34 in the active group and 17 in the sham group. The baseline geometric mean IELT significantly increased from 67 to 123 seconds (P < .01) in the active group, as compared with an insignificant increase from 63 to 81 seconds (P = .17) in the sham group. The increase in mean IELT in the active group was significantly higher than in the sham group (56 vs 18 seconds, P = .01). IELT significantly increased by 3.1 times in the active vs sham group. The mean ratio of fold change (active:sham) was 1.4, significantly different from 1.0 (P = .02). No serious adverse events were reported. CLINICAL IMPLICATIONS Therapeutic use of the vPatch during coitus may become an on-demand, noninvasive, and drug-free treatment for PE. STRENGTHS AND LIMITATIONS To our knowledge, this is the first rigorous study investigating whether transcutaneous electrical stimulation during coitus could improve the symptoms of men with lifelong PE. The study is limited by the small number of patients, the exclusion of patients with acquired PE, the short-term follow up, and the use of a device based on a theoretic mechanism of action. CONCLUSION We demonstrated the possibility to treat lifelong PE by prolonging coitus on demand, using electric stimulation of ejaculation muscles with the vPatch.Clinical trial registration: NCT03942367 (ClinicalTrials.gov).

Abstract
Premature ejaculation (PE) is a prevalent male sexual dysfunction. Current standard treatment regimens include behavioural therapies, topical anaesthetics, dapoxetine and other selective serotonin reuptake inhibitors (SSRIs). Most of the pharmacotherapeutic options target neurotransmitters (such as serotonin and oxytocin) that have a role in the ejaculation mechanism. However, these treatments are mildly effective and only provide a temporary delay in the ejaculation latency time, and PE recurs when the treatment is stopped. Thus, a treatment for PE is urgently needed and research is ongoing to find the ideal PE therapy. The efficacy and safety of topical anaesthetics and SSRIs in delaying ejaculation have been confirmed in many well-designed controlled trials. Both preclinical and clinical studies on new-generation SSRIs are ongoing. Moreover, promising results came from clinical trials in which the efficacy of on-demand PE therapies targeting neurotransmitters other than serotonin, such as α1-adrenoceptor antagonists and oxytocin antagonists, was assessed. Surgical intervention and neuromodulation have been proposed as potential treatment options for PE; however, current PE guidelines do not recommend these treatments owing to safety concerns.

Abstract
PURPOSE Premature ejaculation (PE) is a common sexual dysfunction that significantly affects the quality of life of the patient and their partner. We aimed to compare the efficacy and safety of the combination therapy with biofeedback-guided pelvic floor exercise therapy (BFT) and dapoxetine 30 mg. METHODS Sixty-five patients diagnosed with lifelong PE were included in the study. Patients were divided into three groups as BFT, dapoxetine 30 mg and a combination of BFT and dapoxetine 30 mg. The patients were compared with the intravaginal ejaculatory latency time (IELT) pre-treatment and post-treatment 1st and 3rd months. RESULTS The mean IELTs of the patients in Group 1 were 40 s in pre-treatment, 115 s at the end of the 4th week and 140 s at the end of the 12th week. The IELT values of the patients in Group 2 were 40 s in pre-treatment, 145 s in the 4th week and 170 s in the 12th week. The IELT values were calculated in Group 3 as 42.5 s in pre-treatment, 185 s in the 4th week and 205 s in the 12th week When the IELT was statistically compared between the groups at 1st and 3rd months, the duration in the combination group was found to increase significantly (p < 0.001). CONCLUSION Combination therapy with BFT and dapoxetine 30 mg in lifelong PE treatment is a good alternative with a low side effect profile and acceptable continuous efficiency.

Abstract
INTRODUCTION Premature ejaculation (PE) is a sexual dysfunction of unknown etiology affecting a substantial number of males and deteriorating sexual health and quality of life of the patient and his partner. Treatment still remains challenging; however, pharmacotherapy is considered the mainstay of therapy with behavioral and psychosexual interventions being particularly important as adjudicate procedures, within the context of a holistic approach. AREAS COVERED The authors review the literature on the available medications for PE, both officially registered and non-registered. Currently, only dapoxetine and an anesthetic spray containing lidocaine and prilocaine (Fortacin™) are officially approved, with the rest being used off-label. Herein, updated data regarding the efficacy and safety of the pharmaceutical agents are presented. EXPERT OPINION On-demand dapoxetine is reportedly efficacious and safe in treating lifelong PE and is the first medication to be approved for this purpose. Fortacin has also shown considerable efficacy and may be reliably used on-demand. Phosphodiesterase type 5 inhibitors (PDE5Is) have been found to be effective in the treatment of PE and are therefore recommended either as monotherapy or combined with other therapies (i.e. dapoxetine). Adverse events of any therapy should be taken under consideration. Physicians should encourage patients to discuss their needs and expectations and grade any improvement of their condition with treatment.

Abstract
PURPOSE Selective serotonin re-uptake inhibitors (SSRIs) are frequently used to treat premature ejaculation (PE) in men. We performed a Cochrane review to assess the efficacy of SSRI treatment for PE. MATERIALS AND METHODS We extensively searched a range of databases up to May 2020 and only included randomized controlled trials. RESULTS A total of 31 studies with 8,254 men were included in this analysis. We found that SSRI treatment probably improves self-perceived PE symptoms (defined as a rating of 'better' or 'much better'; risk ratio [RR], 1.92; 95% confidence interval [CI], 1.66-2.23; moderate-certainty evidence) and satisfaction with intercourse (defined as a rating of 'good' or 'very good'; RR, 1.63; 95% CI, 1.42-1.87; moderate-certainty evidence) compared to placebo. Furthermore, SSRI treatment likely improve participants' self-perceived control over ejaculation (defined as rating of 'good' or 'very good'; RR, 2.29; 95% CI, 1.72-3.05; moderate-certainty evidence) and probably lessens distress (defined as rating of 'a little bit' or 'not at all') about PE (RR, 1.54; 95% CI, 1.26-1.88; moderate-certainty evidence). SSRI treatment may increase IELT compared to placebo (mean difference, 3.09 minutes higher; 95% CI, 1.94 higher to 4.25 higher; low-certainty evidence). However, SSRIs may increase treatment cessations due to adverse events compared to placebo (RR, 3.80; 95% CI, 2.61-5.51; low-certainty evidence). CONCLUSIONS SSRI treatment for PE appears to substantially improve a number of outcomes of direct patient importance such as symptom improvement, satisfaction with intercourse and perceived control over ejaculation when compared to placebo.

Abstract
Introduction Before dapoxetine was approved for the treatment of lifelong premature ejaculation (LPE) in China, daily dosing with off-label sertraline was common. Aim To investigate the efficacy of dapoxetine in the treatment of patients with LPE as an alternative to sertraline therapy. Methods This prospective study included LPE patients who previously attempted treatment with sertraline and who agree to receive dapoxetine therapy in our hospital from January 2020 to March 2021. Patients who received any PE therapy in the two months prior to the dapoxetine therapy were excluded. All patients received dapoxetine 30 mg (taken 1–3 hours before sexual intercourse) for 12 weeks, and they were not taking sertraline during the trial. Main Outcome Measure Data on their intravaginal ejaculatory latency time and premature ejaculation profile were recorded before and after the dapoxetine treatment. Clinical Global Impression of Change scores and data on Treatment-Emergent adverse events were collected after treatment. Results A total of 144 patients with LPE completed this study; including 64 patients who reported that previous sertraline treatment was satisfactory (group A) and 80 patients for whom previous sertraline therapy was unsatisfactory in treating PE (group B). Both groups experienced significantly increased intravaginal ejaculatory latency time. Dapoxetine therapy was reported satisfactory by 67.5% of patients with LPE in whom sertraline therapy unsatisfactory according to their Clinical Global Impression of Change score, which was not different from those who reported this result in group A (62.5%). Similar outcomes were also reported for premature ejaculation profile and treatment-emergent adverse events. Conclusion : Although both dapoxetine and sertraline are selective serotonin re-uptake inhibitors, dapoxetine therapy is satisfactory in 67.5% of patients with LPE in whom sertraline treatment unsatisfactory, and the effect of dapoxetine was independent of the effect of sertraline.

A systematic review and meta-analysis of randomized controlled trials of "on-demand" use of tramadol vs "on-demand" use of paroxetine in the management of patients with premature ejaculation. Int J Clin Pract 2021; 75:e14825. [PMID: 34492139 DOI: 10.1111/ijcp.14825] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 08/27/2021] [Accepted: 09/06/2021] [Indexed: 11/27/2022] Open
Abstract
AIM To evaluate the effect of "on-demand" use of tramadol vs "on-demand" use of paroxetine in the management of patients with premature ejaculation (PE). MATERIALS AND METHODS A systematic search of PubMed, EMBASE, Cochrane Library databases and original references of the included articles was performed. PRISMA checklist was followed. The Cochrane Handbook was used to evaluate the quality of the included research. RESULTS A total of seven articles including 663 patients were studied. The results indicated that patients who received on-demand therapy of tramadol or paroxetine showed significant improvement compared with those treated with placebo, as assessed by intravaginal ejaculatory latency time (IELT) (P < .00001 and P = .02, respectively) and sexual satisfaction score (P < .00001 and P < .00001, respectively). Furthermore, Patients who were treated with on-demand tramadol had a better effect than those treated with on-demand paroxetine in respect of IELT (P = .01) and sexual satisfaction score (P = .03). With regard to safety, the most common adverse event for the tramadol group was sleep disturbance and the most common adverse event for the paroxetine group was a headache. No serious adverse event was observed in both groups. CONCLUSIONS Compared with placebo, on-demand therapy of tramadol or paroxetine showed a better improvements in IELT and sexual satisfaction scores. Besides, on-demand tramadol revealed a better effect than on-demand paroxetine for patients with PE, and patients in both groups showed good tolerance.

Abstract
Premature ejaculation (PE) and delayed/inhibited ejaculation (DE) are 2 ejaculatory problems that may negatively affect the sexual relationship and cause distress. Although no specific cause explains these problems when they have been lifelong conditions, understanding both biological and psychological factors may be relevant to treatment choices, with options ranging from pharmacologic to psychobehavioral. Integrating treatment modalities may lead to better outcomes but may also require greater psychological and resource investment from the patient or couple.

Abstract
To analyse the current therapeutic options for patients with premature ejaculation (PE) and highlight their mechanism(s) of action, effectiveness, advantages and limitations. A literature search was conducted using the PubMed database searching for articles exploring different PE treatment modalities. A Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) approach was used to report the results of the literature search. A total of 149 articles were included in this review. The currently available treatment methods for PE include behavioural therapy, local anaesthetics, tricyclic antidepressants, selective serotonin reuptake inhibitors, and selective phosphodiesterase inhibitors. Most PE treatments are either experimental or used off-label. New treatments are certainly warranted to overcome this exasperating sexual dysfunction.

Abstract
CONTEXT The present summary of the European Association of Urology (EAU) guidelines is based on the latest guidelines on male sexual health published in March 2021, with a last comprehensive update in January 2021. OBJECTIVE To present a summary of the 2021 version of the EAU guidelines on sexual and reproductive health. EVIDENCE ACQUISITION A literature review was performed up to January 2021. The guidelines were updated, and a strength rating for each recommendation was included based on either a systematic review of the evidence or a consensus opinion from the expert panel. EVIDENCE SYNTHESIS Late-onset hypogonadism is a clinical condition in the ageing male combining low levels of circulating testosterone and specific symptoms associated with impaired hormone production and/or action. A comprehensive diagnostic and therapeutic work-up, along with screening recommendations and contraindications, is provided. Erectile dysfunction (ED) is the persistent inability to attain and maintain an erection sufficient to permit satisfactory sexual performance. Along with a detailed basic and advanced diagnostic approach, a novel decision-making algorithm for treating ED in order to better tailor therapy to individual patients is provided. The EAU guidelines have adopted the definition of premature ejaculation (PE), which has been developed by the International Society for Sexual Medicine. After the subtype of PE has been defined, patient's expectations should be discussed thoroughly and pharmacotherapy must be considered as the first-line treatment for patients with lifelong PE, whereas treating the underlying cause must be the initial goal for patients with acquired PE. Haemospermia is defined as the appearance of blood in the ejaculate. Several reasons of haemospermia have been acknowledged; the primary goal over the management work-up is to exclude malignant conditions and treat any other underlying cause. CONCLUSIONS The 2021 guidelines on sexual and reproductive health summarise the most recent findings, and advise in terms of diagnosis and treatment of male hypogonadism and sexual dysfunction for their use in clinical practice. These guidelines reflect the multidisciplinary nature of their management. PATIENT SUMMARY Updated European Association of Urology guidelines on sexual and reproductive health are presented, addressing the diagnosis and treatment of the most prevalent conditions in men. Patients must be fully informed of all relevant diagnostic and therapeutic options and, together with their treating physicians, decide on optimal personalised management strategies.

Abstract
Premature ejaculation (PE) is the most prevalent male sexual dysfunction, and the most recently defined. PE is often mistakenly considered a purely psychosexological symptom by patients: the lacking awareness in regards to the pathophysiology and treatments often lead to resignation from the patients' side, making PE the most underdiagnosed sexual complaint. However, an ever-growing body of evidence supporting several organic factors has been developed in the last decades and several definitions have been suggested to encompass all defining features of PE. In the present document by the Italian Society of Andrology and Sexual Medicine (SIAMS), we propose 33 recommendations concerning the definition, pathophysiology, treatment and management of PE aimed to improve patient care. These evidence-based clinical guidelines provide the necessary up-to-date guidance in the context of PE secondary to organic and psychosexological conditions, such as prostate inflammation, endocrine disorders, and other sexual dysfunctions, and suggest how to associate pharmacotherapies and cognitive-behavioral therapy in a couple-centered approach. New therapeutic options, as well as combination and off-label treatments, are also described.

Abstract
BACKGROUND Premature ejaculation (PE) is a common problem among men that occurs when ejaculation happens sooner than a man or his partner would like during sex; it may cause unhappiness and relationship problems. Selective serotonin re-uptake inhibitors (SSRIs), which are most commonly used as antidepressants are being used to treat this condition. OBJECTIVES To assess the effects of SSRIs in the treatment of PE in adult men. SEARCH METHODS We performed a comprehensive search using multiple databases (the Cochrane Library, MEDLINE, Embase, Scopus, CINAHL), clinical trial registries, conference proceedings, and other sources of grey literature, up to 1 May 2020. We applied no restrictions on publication language or status. SELECTION CRITERIA We included only randomized controlled clinical trials (parallel group and cross-over trials) in which men with PE were administered SSRIs or placebo. We also considered 'no treatment' to be an eligible comparator but did not find any relevant studies. DATA COLLECTION AND ANALYSIS Two review authors independently classified and abstracted data from the included studies. Primary outcomes were participant-perceived change with treatment, satisfaction with intercourse and study withdrawal due to adverse events. Secondary outcomes included self-perceived control over ejaculation, participant distress about PE, adverse events and intravaginal ejaculatory latency time (IELT). We performed statistical analyses using a random-effects model. We rated the certainty of evidence according to GRADE. MAIN RESULTS We identified 31 studies in which 8254 participants were randomized to receiving either SSRIs or placebo. Primary outcomes: SSRI treatment probably improves self-perceived PE symptoms (defined as a rating of 'better' or 'much better') compared to placebo (risk ratio (RR) 1.92, 95% confidence interval (CI) 1.66 to 2.23; moderate-certainty evidence). Based on 220 participants per 1000 reporting improvement with placebo, this corresponds to 202 more men per 1000 (95% CI 145 more to 270 more) with improved symptoms with SSRIs. SSRI treatment probably improves satisfaction with intercourse compared to placebo (defined as a rating of 'good' or 'very good'; RR 1.63, 95% CI 1.42 to 1.87; moderate-certainty evidence). Based on 278 participants per 1000 reporting improved satisfaction with placebo, this corresponds to 175 more (117 more to 242 more) per 1000 men with greater satisfaction with intercourse with SSRIs. SSRI treatment may increase treatment cessations due to adverse events compared to placebo (RR 3.80, 95% CI 2.61 to 5.51; low-certainty evidence). Based 11 study withdrawals per 1000 participants with placebo, this corresponds to 30 more men per 1000 (95% CI 17 more to 49 more) ceasing treatment due to adverse events with SSRIs. Secondary outcomes: SSRI treatment likely improve participants' self-perceived control over ejaculation (defined as rating of 'good' or 'very good') compared to placebo (RR 2.29, 95% CI 1.72 to 3.05; moderate-certainty evidence). Assuming 132 per 1000 participants perceived at least good control, this corresponds to 170 more (95 more to 270 more) reporting at least good control with SSRIs. SSRI probably lessens distress (defined as rating of 'a little bit' or 'not at all') about PE (RR 1.54, 95% CI 1.26 to 1.88; moderate-certainty evidence). Based on 353 per 1000 participants reporting low levels of distress, this corresponds to 191 more men (92 more to 311 more) per 1000 reporting low levels of distress with SSRIs. SSRI treatment probably increases adverse events compared to placebo (RR 1.71, 95% CI 1.48 to 1.99; moderate-certainty evidence). Based on 243 adverse events per 1000 among men receiving placebo, this corresponds to 173 more (117 more to 241 more) men having an adverse event with SSRIs. SSRI treatment may increase IELT compared to placebo (mean difference (MD) 3.09 minutes longer, 95% CI 1.94 longer to 4.25 longer; low-certainty evidence). AUTHORS' CONCLUSIONS SSRI treatment for PE appears to substantially improve a number of outcomes of direct patient importance such as symptom improvement, satisfaction with intercourse and perceived control over ejaculation when compared to placebo. Undesirable effects are a small increase in treatment withdrawals due to adverse events as well as substantially increased adverse event rates. Issues affecting the certainty of evidence of outcomes were study limitations and imprecision.

Abstract
Dapoxetine HCl is used for the treatment of premature ejaculation. Dapoxetine is primarily metabolized in the liver and kidney and its metabolites are inactive; resulting in reduced bioavailability. Also, one of the commonly encountered issues in the oral dapoxetine formulae is its bitter taste. Thus, the objective of this study was to develop and to optimize novel dapoxetine taste-masked oral thin films (OTFs), to offer a faster dissolution rate, rapid release pattern, lower liver metabolism, and better patient compliance. To achieve our goal, the applicability of either pullulan or maltodextrin as strip forming polymers were investigated in the preparation of (OTFs), while glycerol was used as a plasticizer. Also, the physicochemical characteristics of dapoxetine in a resinate complex with AmberLiteTM -IRP69 as taste masking were evaluated. Furthermore, a 23 factorial design was used to study and to optimize the effect of the independent variables (strip forming polymer (X1), glycerol (X2) and AmberLiteTM (X3) amounts) on the disintegration time (Y1), degree of elongation (Y2), and degree of in vitro drug release in phosphate buffer pH 6.8 at 5 minutes (Q5min, Y3) as responses. P2 batch (OTF) (pullulan 96 mg, glycerol 12 mg, AmberLiteTM 32 mg, and dapoxetine 30 mg) was identified as an optimized formulation showing an in vitro disintegration time 9.33 s, 35.56% elongation, and 91.43% Q5min; excellent in vivo disintegration time; good overall taste acceptability and stable resinate complex.

Abstract
Dapoxetine is the first oral medication specifically developed for the on-demand treatment of premature ejaculation. The pharmacokinetics and safety of 30 mg (n = 40) and 60 mg (n = 38) dapoxetine in healthy Chinese under fasted and fed states were assessed in 2 studies. Both studies are random, single-center, 2-period, open-label, 2-way crossover designs. Plasma concentration of dapoxetine was determined by high-performance liquid chromatography-tandem mass spectrometry, and the pharmacokinetic parameters were calculated using noncompartmental analysis. Dapoxetine was quickly absorbed and reached maximum concentration 1 to 3 hours after oral administration. Elimination was biphasic, and the plasma concentration decreased to 3% to 7% of maximum concentration by 24 hours while half-life was 15 to 18 hours. Meantime, high-fat meals slightly increased its exposure. Both doses of dapoxetine were well tolerated. The adverse events in the high-dose group under fasted and fed states were 37.9% and 19.0%, respectively.

Abstract
Premature ejaculation (PE) and poor ejaculatory control are multidimensional sexual symptoms estimated to affect almost one-third of men, severely impairing the overall quality of life of patients and their partners. However, patients who do not completely fulfil the definition criteria for PE rarely receive a diagnosis or adequate treatment, with the risk of subsequent progression from initial, subclinical symptoms to clinically overt PE, frequently with other sexual comorbidities. Thus, the current definitions of PE warrant review, in order to consider and propose a new taxonomy encompassing other unaddressed, crucial clinical aspects of PE. These newly proposed criteria include the recommendation for a primary screening for erectile dysfunction (ED), as PE and ED can be comorbid in up to 50% of patients but have never before been considered as a unified clinical entity. In order to facilitate clinical practice and improve clinical management of men with PE and comorbid conditions, we propose and define the new taxonomic clinical entities of subclinical PE (SPE) and loss of control of erection and ejaculation (LCEE). Application of these diagnoses to men who meet the criteria for SPE and/or LCEE, but not the overt conditions, could improve access to treatment for these patients and reduce progression to the more serious clinical disorder.

Abstract
This study assessed whether the reference and test formulations of dapoxetine hydrochloride were bioequivalent under fed and fasting conditions postadministration of a single dose as well as evaluated the safety profile of these 2 formulations. This study was a randomized, single-center, 2-period, open-label, 2-way crossover design study with a washout period of 7 days between each period. The study included 80 subjects, 40 under fed and 40 under fasting conditions. During each study period, the subjects were administered a single oral dose of either the reference or the test formulation, followed by collection of plasma samples 70 hours postdose. High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was performed to determine the concentrations of dapoxetine in plasma samples along with the calculation of Cmax , AUC0-t, and AUC0-inf . In addition, adverse events were monitored to determine the safety of these formulations. The geometric mean ratio (90%CI) for the reference and test formulations was 86% to 100%, 89% to 103%, and 89% to 103% under fasting conditions and 92% to 107%, 91% to 100%, and 92% to 101% under fed conditions for Cmax , AUC0-t , and AUC0-inf , respectively. The 90%CIs for the test/reference ratio for AUC and Cmax were within the acceptable limits of bioequivalence, thus demonstrating bioequivalence for these 2 dapoxetine hydrochloride formulations.

Abstract
To evaluate the safety and efficacy of Chinese medicine, Qiaoshao formula combined with dapoxetine was used for the treatment of premature ejaculation in a real-life setting. Nine hundred and five males diagnosed with premature ejaculation were reviewed in this retrospective cohort study. We divided the patients into two groups: dapoxetine alone and Qiaoshao formula combined with dapoxetine according to actual interventions provided to patients in clinics. The perceived intravaginal ejaculation latency time and the premature ejaculation profile measures markedly improved in both groups. However, in men with severe premature ejaculation (baseline perceived intravaginal ejaculation latency time <1 min) and those with baseline age ≤30 years, the perceived intravaginal ejaculation latency time was slightly but significantly longer with combined therapy than with dapoxetine alone (p < .05). Therefore, combined therapy involving the Qiaoshao formula and dapoxetine proved to safe as well as effective for treating premature ejaculation while prolonging the perceived intravaginal ejaculation latency time, which significantly improved the overall satisfaction of the patient and likely that of the couple.

Abstract
We conducted a systematic review and meta-analysis of published randomised controlled trials of dapoxetine for premature ejaculation. We systematically searched Embase, PubMed, Cochrane, Web of Knowledge, FDA.gov and Clinical Trials.gov for studies reporting dapoxetine in men with premature ejaculation. Efficacy endpoints included intravaginal ejaculatory latency times (IELT), personal distress related to ejaculation (PDRE) and treatment-emergent adverse events (TEAEs) was used to evaluate safety. Data were analysed using a random-effects model. Electronic search identified 276 papers. The final analysis included eight papers (n = 8422 subjects). Analysis of the pooled results indicated efficacy in both IELT (weighted mean difference (WMD) = 1.67, 95% confidence interval (CI) 1.45-1.89) and PDRE (relative risk = 1.26, 95% CI 1.18-1.35). Subgroup analysis indicated efficacy (i.e. increase in IELT) for 30- and 60-mg on-demand dapoxetine (WMD 1.38 (95% CI 1.01-1.75) and 1.62 (95% CI 1.40-1.84) respectively), as well as daily use of 60 mg dapoxetine (WMD 2.18, 95% CI 1.71-2.64). The safety profile was acceptable. Based on the different effects of magnitude of the three dosing regimens, we recommend a stepwise approach, starting with 30 mg on demand, then 60 mg on demand and finally 60 mg dapoxetine daily.

Abstract
To assess the comparative efficacy and safety of drug treatments for premature ejaculation. A systemic review and Bayesian network meta-analysis were executed on randomised controlled trials of drug interventions for premature ejaculation. Intravaginal ejaculation latency time and related adverse effects were outcome measures. A total of 44 RCTs with 11,008 patients were included in our NMA. In therapy <8 weeks, the ranking of drug efficacy was topical creams >selective serotonin reuptake inhibitor (SSRI)+ phosphodiesterase 5 inhibitor (PDE5i) > PDE5i > sertraline > clomipramine > paroxetine > dapoxetine 60 milligram (mg) > dapoxetine 30 mg > fluoxetine>citalopram > duloxetine>placebo. In therapy ≥ 8 weeks, the ranking of drug efficacy was SSRI + PDE5i > topical creams > paroxetine > tramadol > PDE5i > fluoxetine > dapoxetine 60 mg > dapoxetine 30 mg > clomipramine>citalopram > placebo. For total adverse events, clomipramine, dapoxetine 30 mg, dapoxetine 60 mg, paroxetine, PDE5i, SSRI + PDE5i and tramadol had a higher risk than placebo. In conclusion, in ≥8 weeks of therapy, the drug combination of SSRI + PDE5i was the most effective PE therapy. In <8 weeks of therapy, the efficacy of local anaesthetics was best. All drug treatments were ranked better than placebo. In general, drugs with better effects had more obvious side effects.

Abstract
The aim of our study was to compare melatonin levels of patients with lifelong premature ejaculation (LPE) (n:60) with healthy controls (n:30) and to investigate the changes of melatonin levels in the treatment with dapoxetine and sertraline. Age, body mass index, duration of marriage, weekly intercourse number, International Index of Erectile Function scores, Intravaginal Ejaculation Latency Time (IELT) and melatonin levels were recorded. LPE patients were divided into two treatment groups. The first group was included 30 patients, who received 60 mg dapoxetine for six weeks, twice a week, an hour before intercourse. The second group received 50 mg of sertraline daily, for six weeks. IELT and melatonin measures were repeated after the treatment. IELT (dapoxetine group: 41.22 ± 21.3 s, sertraline group: 48 ± 23.11 s, control group: 195.54 ± 84.14 s; p < .001) and melatonin levels (dapoxetine group: 5.75 ± 2.04 pg/mL, sertraline group: 5.49 ± 2.88 pg/mL, control group: 13.4 ± 12.09 pg/mL; p < .001) of both LPE groups were significantly lower than control group. Following the six-week sertraline (before: 48 ± 23.11 s, after: 101.01 ± 59.55 s; p < .001) and dapoxetine (before: 41.22 ± 21.3 s, after: 97.39 ± 44.1 s; p < .001) treatments, IELT increased. The melatonin levels increased in the sertraline group (before: 5.49 ± 2.88 pg/mL, after: 10.6 ± 7.37 pg/mL; p < .001). Our results indicate that melatonin levels of LPE patients are lower than levels of healthy volunteers. Furthermore, we found a significant increase in melatonin levels following sertraline treatment.

Abstract
The relationship between 5-hydroxytryptamine transporter-linked promoter region (5-HTTLPR) gene and lifelong premature ejaculation (LPE) risk was discussed widely for the last few years, which was still controversial and remained to be explored. We performed the meta-analysis with 8 reliable research, which were searched in the following databases: PubMed, Embase and Cochrane Library. We also performed random and fixed effects models to evaluate the odds ratios (ORs) and 95% confidence intervals respectively. By pooling all included studies, we found that SS genotype of 5-HTTLPR polymorphism was linked with significantly higher PE risk in Caucasian population (OR =0.635, 95% CI: 0.417–0.958, I2=0.311, P=0.035), and S-allele of 5-HTTLPR polymorphism increased the risk of LPE significantly in Asian population (OR =0.656, 95% CI: 0.539–0.799, I2=0.435, P<0.001). However, no significant was observed between 5-HTTLPR gene polymorphism and LPE risk in overall studies. Further studies were anticipated to be done.

Abstract
This trial aimed to assess the efficacy of on-demand oral dapoxetine versus topical lidocaine treatments for lifelong PE. Cases with lifelong PE were randomised to start treatment by oral dapoxetine 60 mg or topical lidocaine 10% spray. The intravaginal ejaculatory latency time (ILET), validated Arabic Index for PE (AIPE), Sexual Health Inventory for Men (SHIM) and frequency of intercourse/week were recorded at the baseline and after 12 weeks treatment period of the first medication before two weeks washout period and then crossing over to the other one for another 12 weeks. Results showed that both medications significantly increased both IELT and AIPE scores compared with the baseline being significantly better with topical lidocaine (63.44 s, 179.4 s versus 21.87 s, p < .05). Significant decrease of SHIM score was recorded with lidocaine but not with dapoxetine. Global Efficacy Question for the patient's assessment of the effectiveness of drugs showed that lidocaine was described as being effective by 43 cases and ineffective by 12 cases, oral dapoxetine was described as being effective by 16 cases and ineffective by 39 cases. From these accumulated data, it is concluded that topical lidocaine is more effective on-demand therapy for lifelong PE compared with oral dapoxetine.

Abstract
The incidence of premature ejaculation (PE) has been on the rise over the years. Thus, significant research efforts have been directed toward understanding the pathogenesis and hence treatment of PE. Here, we performed a comprehensive analysis of the worldwide trends in research outputs in the field of PE. This study investigated the universal findings of previous PE studies and the trending issues surrounding the condition. We employed the Web of Science Core Collection for data collection. The Excel (2016) and CiteSpace IV were used for information analysis. The information was categorized using journal names, institutions, research frontiers, citation reports, regions/countries, and authors. A sum of 886 publications concerning PE between 2008 and 2018 were identified as of July 6, 2019. The highest number of publications was identified in the Journal of Sexual Medicine published. The United States of America (USA) had the highest number of publications and H-index value. The highest co-citations were from Waldinger MD. The most common keyword was 'drug treatment'. A steady pattern was observed for PE publications done between the period of 2008-2018. Thus, the USA is at the forefront of research on PE research. The interesting advanced research frontiers were drug treatment, circumcision, and sertraline.

Abstract
This study aimed to appraise the effectiveness and tolerability of lidocaine 5% spray in the treatment of patients with premature ejaculation (PE). The current study has been designed as a randomized single-blind placebo-controlled clinical trial. It was done on 150 lifelong PE patients with normal erection. They were randomized evenly categorized into two treatment groups. Group 1 (n = 75); was given on demand lidocaine 5% spray for 8 weeks. Group 2 (n = 75); was given placebo in the form on demand alcohol spray for 8 weeks. All medications were applied on the glans penis for 10-20 min, and then cleaned before planned sexual intercourse. Patients were evaluated with the Arabic Index of Premature Ejaculation (AIPE) scores, intravaginal ejaculatory latency times (IELTs), and frequency of sexual intercourse before and after treatments. The mean values of the AIPE scores, IELTs, and sexual intercourse frequency in the lidocaine 5% spray group were statistically significant increased than the group of placebo after treatment (P value 0.0001). The present study deduced that local use of lidocaine 5% spray on glans penis 10-20 min prior to sexual intercourse could significantly improve PE patients, with tolerated local adverse effects.

Abstract
BACKGROUND Premature ejaculation (PE) is a common sexual dysfunction for which selective serotonin reuptake inhibitors (SSRIs) have been used effectively for treatment. However, compliance with therapy and predictors of long-term SSRI use in the treatment of PE are not well known. AIM To analyze our experience with drop-out rates with fluoxetine in the primary PE population and to identify predictors of continued use of this agent. METHODS Men with primary PE constituted who used fluoxetine and had at least 12 months follow-up constituted the study population. Subjects underwent a comprehensive interview to ascertain self-reported (non-stopwatch) intravaginal ejaculatory latency time (IELT), self-rated control over ejaculation, and personal and patient-reported partner distress due to PE. Patients were treated with fluoxetine 20 mg daily, with the possibility of dose titration up or down based on efficacy and side effects. OUTCOMES The PE parameters of interest included self-reported IELT, self-rated control over ejaculation, personal and partner distress due to PE, and medication adherence. RESULTS 130 men were included in the study. Dropout rates at 6 and 12 months were 56% and 72%. Self-rated "poor" ejaculatory control decreased from 98%-41% (P < .01), high personal distress from 47%-11% (P < .01), and high partner distress rates from 72%-27% (P < .01). Predictors of continued use at 12 months included high partner distress, being unpartnered, and having a post-treatment IELT ≥5 minutes (P < .01). Overall side effects included headache (5%), dizziness (4%), nausea (5%), nervousness (5%), and sleepiness (8%); however, moderate to severe side effects reported included nausea (2%), sleepiness (2%), headache (2%), and dizziness (2%). CLINICAL IMPLICATIONS Compliance with SSRIs is a well-described problem in the depression literature, but data are sparse regarding continued use of SSRIs in the treatment of PE. STRENGTHS AND LIMITATIONS We report on 12-month compliance with SSRIs for the treatment of PE. Our early compliance rates were more encouraging than what has been reported in the past. However, IELT was self-reported and not measured objectively, and we did not use validated patient-reported outcomes but rather self-reported ejaculatory control and distress levels, which have limitations. CONCLUSIONS Fluoxetine is an effective agent for the treatment of PE with significant improvement realized in IELT, ejaculatory control, and distress levels for both men and their partners. Despite its efficacy, continued use of fluoxetine beyond 6 months is poor. Jenkins LC, Gonzalez J, Tal R, et al. Compliance with Fluoxetine Use in Men with Primary Premature Ejaculation.

Abstract
BACKGROUND Premature ejaculation (PE) is a form of male sexual dysfunction. As people's lifestyle changes and the population ages, the incidence of PE continues to increase. Chinese patent medicines have been widely used in clinical practice as derivatives of traditional Chinese medicine (TCM). Many clinical trials have proven that Chinese patent medicine has a significant effect in the treatment of PE. In this systematic review, we aim to evaluate the effectiveness and safety of Chinese patent medicine for PE. METHODS We will search for PubMed, Cochrane Library, AMED, Embase, WorldSciNet, Nature, Science online and China Journal Full-text Database, China Biomedical Literature CD-ROM Database, and related randomized controlled trials included in the China Resources Database. The time is limited from the construction of the library to September 2019. We will use the criteria provided by Cochrane 5.1.0 for quality assessment and risk assessment of the included studies, and use the RevMan 5.3 and Stata 13.0 software for meta-analysis of the effectiveness, recurrence rate, and symptom scores of PE. ETHICS AND DISSEMINATION This systematic review will evaluate the efficacy and safety of TCM for treating PE. Because all of the data used in this systematic review and meta-analysis have been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process Trial. TRIAL REGISTRATION NUMBER PROSPERO CRD42017065316.

Abstract
Premature ejaculation (PE) is a highly prevalent male sexual dysfunction that is often neglected, presenting a currently unmet therapeutic need. The classification of PE has historically been varied and at times ambiguous, contributing to inaccurate prevalence estimates. This review uses the International Society for Sexual Medicine (ISSM) definition of PE, which includes reduced ejaculatory latency, lack of control and associated negative personal consequences. Patient assessment and management options differ depending on the classification of PE and it is the role of the clinician to appropriately classify patients and be aware of the correct management strategies. This review provides an overall background of PE in terms of classification and underlying physiology, patient assessment and management strategies along with the scientific rationale for treatment. Patients with lifelong and acquired PE are most likely to benefit from combination therapy of pharmacological treatment in the form of selective serotonin re-uptake inhibitor dapoxetine, psychosexual behavioural therapy and psychological therapy.

Abstract
Premature Ejaculation (PE) is a very common and disturbing sexual dysfunction in men. Currently available treatment modalities are associated with limited efficacy and low treatment adherence. In this prospective, single-blinded, self-controlled study, we evaluated the efficacy and safety of transcutaneous electrical stimulation (TES) for the treatment of (PE). We included 23 patients aged 20-60 (mean: 38.7) with lifelong PE. On the first visit, we delivered either TES or sham treatment to the perineum, based on the enrollment order. For stimulation, we used a commercial neuromuscular electrical stimulation device. The patients were invited for the second visit after at least 7 days for receiving the alternating treatment. During the treatment sessions, the patients were left alone in a privet silent room to masturbate and a stopwatch was used to measure their masturbation ejaculatory latency time (MELT). The patients also filled-out safety questionnaires after each visit and on each of the 3 following days. Of the 20 patients who completed the study, 17 (85%) experienced prolonged MELT under TES compared with the sham treatment. Mean MELT values increased 3.5-folds under TES (p = 0.0009). We demonstrated a significant increase in MELT in lifelong PE patients using TES. This therapeutic option may have the potential to become an on-demand treatment option for PE. Future studies with wireless devices are needed to confirm the efficacy and safety of this treatment concept during intercourse.

Abstract
Introduction To assess the treatment efficacies of paroxetine, fluoxetine and dapoxetine in patients with lifelong premature ejaculation (PE). Material and methods One hundred and seventy male patients with lifelong PE were included in our study. Premature ejaculation profile (PEP) and Intravaginal ejaculation latency times (IELT) were recorded. Paroxetine 20 mg/d was given in Group 1 (n = 64), fluoxetine 20 mg/d was given in Group 2 (n = 47) and dapoxetine 30 mg on demand (at least two times/week) was given in Group 3 (n = 59) patients. After 1 month of treatment, the patients' IELT, PEP and patient reported clinical global impression of change (CGIC) were completed. Results The mean age was 36 ±9.2 years. There was no difference between the groups' age, PEP and IELT before treatment (p >0.05). PEP and IELT improved in all three groups (p <0.001). The changes in the 1st and 3rd questions of PEP was significantly higher in group 1 than in the other groups (pPEP-1 = 0.042, pPEP-3 = 0.001). The changes in the 2nd and 4th questions of PEP were similar between groups (pPEP-2 = 0.444, pPEP-4 = 0.442). In group 1 and 3 IELT changes were better than group 2 (pIIEL1-3 = 0.297, pIIEL1-2 = 0.017, pIIEL2-3 = 0.100). There was no difference between CGIC scores (p = 0.087). The treatment was terminated by 8 patients in Group 1 and 9 patients in Group 2 because of side effects. Conclusions While paroxetine treatment seemed to be better than the other medications, dapoxetine 30 mg treatment has less side effects than the two others and its' on demand usage makes it more prominent than the others.

Abstract
INTRODUCTION Factors that impact the pharmacokinetics of dapoxetine, a 5-HT selective reuptake inhibitor used for the treatment of premature ejaculation, have not been clearly identified. This study aimed to evaluate the effects of consumption of a high-fat meal and cytochrome P450 (CYP) 2D6 polymorphisms on the pharmacokinetics of dapoxetine in healthy Chinese men. METHODS Twenty-two healthy volunteers were enrolled and classified based on their CYP2D6 genotype. A single-dose, two-treatment (fasted and fed), two-period, one-sequence pharmacokinetic study was conducted. Plasma concentrations of the drug were determined using LC-MS. Pharmacokinetic parameters were calculated by a noncompartmental analysis. RESULTS The consumption of food significantly prolonged the time required for dapoxetine to reach its peak concentration and area under the concentration-time curve (AUC0-48) (p < 0.01). Compared with that in *1/*10 and *2/*10 genotypes, the dapoxetine plasma exposure in *10/*10 individuals was notably increased. The AUC0-48 value for *10/*10 was significantly higher than that for *1/*10 and *2/*10 (p < 0.05). CONCLUSION The obtained results demonstrated that a high-fat meal and the CYP2D6 *10/*10 genotype influence the pharmacokinetic properties of dapoxetine and may thus have potential clinical implications. Future studies focusing on safe dapoxetine dosing based on CYP2D6 genotyping are needed. FUNDING This study was partially sponsored by Xiamen Fuman Pharmaceutical Co., Ltd.

Abstract
Background The aim of this study was to assess the efficacy and safety of “on-demand” dapoxetine in the treatment of premature ejaculation (PE). Material/Methods We performed a meta-analysis of intravaginal ejaculatory latency time (IELT), patient-reported global impression of change (PGIC), perceived control over ejaculation (PCOE), and drug-related adverse effects (AEs). We searched Medline, PubMed, Embase, CNKI, Wanfang, and VIP databases up to May 30, 2018 with the following search terms: “dapoxetine” or “SSRIs” and “premature ejaculation” or “sexual dysfunction”. Results Our analysis included 11 RCTs (8521 cases and 4338 controls). We found that IELT, PGIC, and PCOE in PE patients with “on-demand” dapoxetine were significantly higher than in the control group, and we observed higher proportions in 60 mg vs. 30 mg dapoxetine. The AEs were mild and tolerable. Conclusions “On-demand” dapoxetine is effective and safe for patients with PE, and a dose of 60 mg may be more effective than 30 mg.

Abstract
BACKGROUND The Premature Ejaculation Profile (PEP) is a patient-reported outcome (PRO) measure that is widely used in clinical research in men with premature ejaculation (PE) but has not been fully validated for men meeting the current International Society for Sexual Medicine (ISSM) definition of lifelong PE. AIM To explore the content validity of the PEP (original 1-month recall version and new event-driven version) in men meeting current definitions of lifelong PE and to understand the relevance of the concept of ejaculation control. METHODS In-depth individual interviews were conducted with 24 men in a stable heterosexual relationship, including 15 with lifelong PE, 4 with acquired PE (with intravaginal ejaculation latency time values confirmed during a 4-week period of no treatment), and 5 with no sexual dysfunction. Initial concept elicitation explored individual experiences of having PE (in those with PE), experiences of control, and impact on sexual life. This was followed by a cognitive debriefing of the PEP versions. MAIN OUTCOME MEASURE Thematic analysis was used to identify key concepts of PE, understand the experience of control in men with and without PE, and confirm understanding and relevance of questions from original and event-driven versions of the PEP. RESULTS The interviews confirmed substantial negative consequences for men with lifelong PE. Men with and without PE could describe ejaculation control (or lack of it). The PEP was shown to cover the key concepts in PE, and the questions were easily understood in both the original or event-driven versions. The items were comprehensive, and the concept of ejaculation control was confirmed. A 1- or 2-category change in each item of the PEP was considered clinically meaningful. CLINICAL IMPLICATIONS The PEP (original and per-event) has strong content validity for use in clinical research studies of men meeting the ISSM definition of lifelong PE. STRENGTHS & LIMITATIONS This study addressed gaps in previously published research on the development and validation of the PEP and also confirmed that a new event-driven version is also suitable for use in research. However, the study was limited mainly to men meeting a strict definition of lifelong PE; in addition, homosexual men and those not in stable long-term relationships were not studied. CONCLUSION Both the original and per-event PEP versions were shown to have strong content validity and be acceptable for use in men with lifelong PE. Burbridge C, Symonds T, Osterloh IH, et al.

Abstract
To evaluate the overall treatment benefits of premature ejaculation desensitisation therapy combined with 30 mg dapoxetine hydrochloride treatment on patients with primary premature ejaculation (PPE). Ninety-nine PPE patients were randomly divided into two groups at the ratio of 2:1. Sixty-six PPE patients received premature ejaculation desensitisation therapy accomplished by Weili Automatic Semen Collection-Penis Erection Detection and Analysis workstation (WLJY-2008) combined with 30 mg dapoxetine hydrochloride treatment (DTCD group), and another 33 patients received 30 mg dapoxetine hydrochloride-only treatment (DO group). Intravaginal ejaculation latency time (IELT) and premature ejaculation profile (PEP) were recorded before and during the treatment, and clinical global impression of change (CGIC) in PPE was recorded at the fourth week and the end of the treatment and the items. In both groups were significantly improved (p < 0.0001) in IELT, PEP and CGIC for premature ejaculation compared with baseline, and DTCD treatment showed a more significant improvement on PPE patients in the items compared with DO treatment (p < 0.05). Thus, premature ejaculation desensitisation combined with dapoxetine therapy may be a better choice for improving premature ejaculation with PPE.

Abstract
BACKGROUND Premature ejaculation (PE) is one of the most common male sexual dysfunctions, which can directly harm men's self-esteem and affect the stability of the relationship between husband and wife. To some extent, PE even affects the harmony and stability of society. So, men's health has gained more and more attention. As one of the long-acting selective serotonin reuptake inhibitors (SSRIs), fluoxetine has been proven to be effective in the treatment of PE by many trails. In this study, we aim to evaluate the effectiveness and safety of fluoxetine for PE to provide the newest evidence for clinical use. METHODS AND ANALYSIS Literature research will be divided into 2 parts: electronic search and manual search. We will search PubMed, EMBASE, The Cochrane Library, the China National Knowledge Infrastructure (CNKI), China Biology Medicine disc (CBMdisc), the China Science and Technology Journal database (VIP), and the Wanfang database online. We will select the eligible studies published up to December 31, 2018. Manual searches mainly retrieve dissertations, ongoing trails, internal reports, and so on. We use intravaginal ejaculatory latency time (IELT) as the primary outcome of PE and we also care about the following indexes: PE Diagnostic Tool (PEDT); Arabic index of PE (AIPE); Index of PE (IPE). In addition, we will carefully observe the patient's adverse reactions during the medication. Two reviewers will read the articles, extract the data information, and assess the risk of bias independently.

Efficacy and safety of dapoxetine/sildenafil combination tablets in the treatment of men with premature ejaculation and concomitant erectile dysfunction-DAP-SPEED Study. Int J Impot Res 2019; 31:92-96. [PMID: 30705437 DOI: 10.1038/s41443-019-0122-2] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Revised: 12/29/2018] [Accepted: 01/10/2019] [Indexed: 12/31/2022]
Abstract
Premature ejaculation (PE) and erectile dysfunction (ED) are the most prevalent sexual disorders in men. ED is commonly reported among patients with PE. Although recent guidelines recommend to treat ED first in men with both PE and ED, this recommendation is not based on evidence and there are limited data about the efficacy and safety of dapoxetine/sildenafil combination therapy for these patients. The aim of this study is to evaluate the clinical efficacy and safety of the dapoxetine/sildenafil combination (Dapoxil® 30/50 mg film-coated tablet) in the treatment of patients with PE and concomitant ED. In a single-center, single-arm, open-label clinical study conducted between October 2016 and September 2017, 74 patients with lifelong or acquired PE and ED were included. All patients were instructed to record their intravaginal ejaculatory latency time (IELT) with a stopwatch for 4 weeks. After the screening, they were requested to complete Premature Ejaculation Diagnostic Tool (PEDT), Premature Ejaculation Profile (PEP), and International Index of Erectile Function-Erectile Function (IIEF-EF) questionnaires before the treatment. The patients received on demand Dapoxil® 1-3 h before sexual intercourse for the next 4 weeks (2 days a week and no more than once a day). The patients were also assessed with global impression of change (GIC) question for the treatment satisfaction and the side effects were recorded. The study was completed with 53 patients (53/74, 71.62%). Mean age of the patients was 45.32 ± 10.05 years. At the end of the 4-week treatment period, the geometric mean IELT of the patients significantly increased (from 22.72 ± 15.16 to 68.25 ± 82.33 s; p < 0.001). Similarly, significant improvements were observed in the mean PEP index score (0.86 ± 0.72 vs. 2.36 ± 1.13; p < 0.001) and mean IIEF-EF domain score (13.17 ± 3.33 vs. 24.60 ± 3.96; p < 0.001). According to the GIC results, 81.13% of the patients were satisfied with the treatment. Non-serious adverse events occurred in 10 patients (18.87%) and 4 (7.55%) of these patients dropped out of the treatment. The most common adverse events were headache, palpitation, and flushing. The dapoxetine/sildenafil combination therapy significantly improves the IELT values and patient reported outcome measures of PE patients who also suffer from ED. Although several side effects were reported, these were mild and transient.

Comparative efficacy and safety of phosphodiesterase-5 inhibitors with selective serotonin reuptake inhibitors in men with premature ejaculation: A systematic review and Bayesian network meta-analysis. Medicine (Baltimore) 2018; 97:e13342. [PMID: 30544399 PMCID: PMC6310608 DOI: 10.1097/md.0000000000013342] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2018] [Accepted: 10/29/2018] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND We performed the network meta-analysis (NMA) and systematic review involved all evidence from relevant trials to compare the efficiency and safety of various types of selective serotonin reuptake inhibitors (SSRI) and phosphodiesterase-5 inhibitors (PDE5i) in patients with premature ejaculation (PE). METHODS We conducted comprehensive searches of peer-reviewed and grey literature. PubMed, the Cochrane Library Central Register of Controlled Trials, Embase were searched for randomized controlled trials published up to June 1, 2017. The primary outcome was intravaginal ejaculation latency time (IVELT) and adverse effects (AEs). We performed pairwise meta-analyses by random effects model and network meta-analysis by Bayesian model. We used the GRADE framework to assess the quality of evidence contributing to each network estimate. RESULTS Of 3046 titles and abstracts initially identified, 17 trials reporting 5739 participants were included. Considering IVELT in the NMA, paroxetine plus sildenafil and sildenafil alone are both superior to placebo (MD: 1.75, 95% CrI: 0.05 to 3.78; MD 1.43, 95% CrI 0.003 to 2.81). Sildenafil is superior to sertraline (MD: 1.63, 95% CrI: 0.10 to 2.79). Considering AEs, placebo demonstrated obviously lower risk comparing to paroxetine, sildenafil and paroxetine plus sildenafil (OR 0.20, 95% CI: 0.05 to 0.52; OR 0.23, 95% CI: 0.04 to 0.80; OR 0.45, 95% CI: 0.01 to 0.92). Compared with tadalafil plus paroxetine, dapoxetine showed significantly less AEs (OR 0.23, 95% CI 0.02 to 0.96). CONCLUSIONS Our study concluded that although paroxetine plus sildenafil and sildenafil alone both demonstrated significant IVELT benefit compared with placebo, significant increase of AEs risk was also observed. Furthermore, sildenafil alone was superior to sertraline in efficacy with comparable tolerability.

Abstract
PURPOSE The purpose of the study was to conduct a systematic evaluation of the different general prescribed drugs for premature ejaculation (PE). METHODS A systematic literature search of MEDLINE, Cochrane Central Register of Controlled Trials, and Web of Science for Systematic Reviews was performed on 1 March 2018. Intravaginal ejaculation latency time (IELT) was the main outcome. Analysis was performed under multivariate random-effects network model and efficacies of drugs were ranked with surface under the cumulative ranking (SUCRA) probabilities. RESULTS A total of 48 studies were reviewed and 40 of them were further enrolled into network meta-analysis. The majority of RCTs were of unclear methodological quality. Pooled evidence suggested that topical anaesthetic creams (TAs), tramadol, selective serotonin reuptake inhibitors (SSRIs), and phosphodiesterase type 5 inhibitors (PDE5is) are more effective at prolonging IELT comparing with placebo. TAs (90%) on demand (OD) and PDE5is plus SSRI (89.8%) had the highest SUCRA, which meant the most probable to be the most effective intervention. CONCLUSIONS We recommend the initial use of dapoxetine 30 mg OD for PE because it has been tested in largest and better designed clinical trials rather than it is more effective than the other drugs studied. TAs and tramadol 50 mg OD can be used as a viable alternative to oral treatment with SSRIs. PDE5is combined with SSRIs are more effective than SSRIs monotherapy but are also associated with more side effects. PDE5is OD can be recommended to PE patients with ED.

Abstract
BACKGROUND The safety and efficacy of dapoxetine for the treatment of premature ejaculation (PE) is still controversial. Thus, we decided to conduct a meta-analysis using trial sequential analysis (TSA) to determine the sufficiency of conclusions. OBJECTIVE Evaluate the efficacy and safety of dapoxetine in the treatment of patients with PE and assess the reliability of the findings. DESIGN Meta-analysis of randomized controlled trials (RCTs). METHODS Electronic databases including PUBMED, EMBASE, Cochrane Library, CNKI and Wanfang data were reviewed up to July 2017. RCTs evaluating the efficacy of dapoxetine in patients with PE and reporting intravaginal ejaculatory latency time (IELT), patient global impression of change (PGIC) and/or adverse events (AEs) were included. MAIN OUTCOME MEASURES Mean differences between trials in efficacy for IELT, and risk ratios for PGIC and treatment-emergent AEs. SAMPLE 8 RCTs. RESULTS For IELT and PGIC, significant effects were found for all doses of dapoxetine versus placebo, and similar results were obtained in subgroups of the 30-mg dose versus 60-mg dose. There were also statistically different dose-related effects on AEs. Trial sequential analysis showed that the result of our meta-analysis was confirmed and further trials are unnecessary. CONCLUSIONS The evidence suggests that dapoxetine may be a safe and effective drug for patients with PE. REGISTRATION Not registered, no published protocol. CONFLICT OF INTEREST No relationship with manufacturer of drug.

Abstract
BACKGROUND Premature ejaculation is a common sexual dysfunction disease in adult males. It can be divided into primary and secondary premature ejaculation. Acupuncture is widely used in the treatment of premature ejaculation in China. There are many clinical trials confirmed that acupuncture can prolong the ejaculation latency in the vagina. We aim to use a meta-analysis to evaluate the efficacy and safety of acupuncture for premature ejaculation. METHOD We will systematically search all randomized controlled trials (RCTs) by electronic and manual search, until June 31, 2018. Electronic retrieval of the database includes Medline, EMBASE, the Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, the Cochrane Library, the Chinese BioMedical Literature Database, the China National Knowledge Infrastructure (CNKI), the China Science and Technology Journal database (VIP), and the Wanfang database. Manual search will retrieve gray literature, including unpublished conference articles. The primary outcomes include the Intravaginal Ejaculatory Latency Time (IELT). At the same time, Premature Ejaculation Diagnostic Tool (PEDT), Arabic index of Premature Ejaculation (AIPE), Index of Premature Ejaculation (IPE) will be the secondary outcomes. Two reviewers will independently read the articles, extract the data information, and give the assessment of risk of bias. Data analysis will be used the special software like RevMan (version 5.3) and EndNote X7. ETHICS AND DISSEMINATION This systematic review will evaluate the efficacy and safety of acupuncture for premature ejaculation. This review does not require ethical approval and will be reported in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER PROSPERO CRD42018092783.
