A review on pharmacological options for the treatment of erectile dysfunction: state of the art and new strategies. Expert Opin Pharmacother 2023; 24:1375-1386. [PMID: 37272398 DOI: 10.1080/14656566.2023.2221785] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Accepted: 06/01/2023] [Indexed: 06/06/2023]
Abstract
INTRODUCTION Erectile dysfunction (ED) affects between 12.9% and 28.1% of men worldwide, presenting a strong aged-correlated prevalence. Several pharmacological treatments are currently available for ED, which can be classified into oral, injection, and topical/intraurethral therapies. AREAS COVERED Extensive research on PubMed/MEDLINE until February 2023 was performed. For each of the aforementioned drug classes, available molecules, and formulations, their efficacy and most common adverse events as well as general guidelines on prescription were investigated and extensively described. A glimpse into future directions regarding ED pharmacotherapy is also present. EXPERT OPINION In recent years, there have been significant developments in pharmacological treatments for ED. It is essential for physicians to identify the best treatment option for patients based on their preferences and sexual habits. The treatment approach for ED has shifted from a sequential to a parallel paradigm, where all treatment options are available as first-line therapies. While there are promising regenerative therapies for ED, such as shockwaves and platelet-rich plasma injections, pharmacological treatment is still the most effective option for most patients.

Abstract
INTRODUCTION Erectile dysfunction (ED) is a substantial cause of dissatisfaction among many men. This discontentment has led to the emergence of various drug treatment options for this problem. OBJECTIVES Unfortunately, due to various interactions, contraindications, and side effects, systemic therapies such as phosphodiesterase-5 inhibitors (including sildenafil, tadalafil, vardenafil, avanafil, etc.) are not welcomed in many patients. These problems have led researchers to look for other ways to reduce these complications. METHODS This article holistically reviews the efficacy of topical prostaglandins and their role in treating ED. We sought to provide a comprehensive overview of recent findings on the current topic by using the extensive literature search to identify the latest scientific reports on the topic. RESULTS In this regard, topical and transdermal treatments can be suitable alternatives. In diverse studies, prostaglandins, remarkably PGE1 (also known as alprostadil), have been suggested to be an acceptable candidate for topical treatment. CONCLUSION Numerous formulations of PGE1 have been used to treat patients so far. Still, in general, with the evolution of classical formulation methods toward modern techniques (such as using nanocarriers and skin permeability enhancers), the probability of treatment success also increases.

Combination therapy with topical alprostadil and phosphodiesterase-5 inhibitors after failure of oral therapy in patients with erectile dysfunction: a prospective, two-arm, open-label, non-randomized study. Int J Impot Res 2022; 34:164-171. [PMID: 33483603 DOI: 10.1038/s41443-020-00400-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 12/03/2020] [Accepted: 12/04/2020] [Indexed: 01/30/2023]
Abstract
Phosphodiesterase type 5 inhibitors (PDE5Is) are the first-line therapeutic option for erectile dysfunction (ED), while second-line therapy includes the alprostadil. Due to the different pharmacodynamic mechanism of PDE5Is and alprostadil, a synergistic action is conceivable when they are administered in combination. The aim of present study was to evaluate the efficacy and safety of combination therapy with PDE5I and topical alprostadil in patients with ED non-responders to PDE5I alone. We designed a prospective, two-arm, open-label, non-randomized study. Patients over 18 years old, with a stable sexual relationship for at least 6 months, and ED non-responders to PDE5I monotherapy were included in the study. At baseline the variables assessed were 5-item version of the International Index of Erectile Function (IIEF-5), and Sexual Encounter Profile Questions 2 and 3 (SEP-2 and SEP-3). In addition, all subjects underwent penile dynamic duplex ultrasonography. All patients were assigned to the monotherapy group (Group A) or combination therapy group (Group B) based on their preference. Topical alprostadil 300 μg/100 mg (Virirec®) was the treatment assigned to Group A, while the combination therapy with the last PDE5I taken (at the maximum recommended dose) plus topical alprostadil 300 μg/100 mg (Virirec®) was assigned to Group B. After 3 months from assignment to groups were evaluated IIEF-5, SEP-2 and SEP-3 regarding the last sexual intercourse, and Global Assessment Questionnaire-Questions 1 and 2 (GAQ-1 and GAQ-2). All adverse events (AEs) that occurred during the study period were recorded. A total of 170 patients were included in the study (72 in Group A and 98 in Group B). Fifty-two patients were previously treated with sildenafil 100 mg (30.6%), 6 with vardenafil 20 mg (3.5%), 56 with tadalafil 20 mg (32.9%), and 56 with avanafil 200 mg (32.9%). No significant differences among the study groups were found at baseline (p > 0.05). The mean IIEF-5 score increased significantly in Group B after treatment compared to baseline (12.4 ± 3.4 vs. 17.1 ± 4.5; p < 0.001), conversely patients in Group A showed no significant increase (12.2 ± 2.5 vs. 12.7 ± 3.1; p = 0.148). The number of affirmative responses to SEP-2 was significantly higher after treatment compared to baseline only in Group B (57 vs. 78; p < 0.001). The number of affirmative responses to SEP-3 was significantly higher after treatment compared to baseline in both groups (p < 0.001). The number of affirmative responses to GAQ-Q1 and GAQ-Q2 was significantly higher in Group B compared to Group A (p < 0.001). A total of 59 (34.7%) patients experienced AEs. They were mild, self-limited, and did not cause discontinuation of treatment. No episode of priapism was recorded. No statistically significant difference was recorded between the AEs of the two groups, except for facial flushing that was reported only in Group B (p = 0.021). The combination therapy with topical alprostadil and PDE5I seems to be more effective than topical alprostadil alone without worsening the safety of the treatment.

Abstract
Diabetes mellitus (DM), a chronic metabolic disease characterised by elevated levels of blood glucose, is among the most common chronic diseases. The incidence and prevalence of DM have been increasing over the years. The complications of DM represent a serious health problem. The long-term complications include macroangiopathy, microangiopathy and neuropathy as well as sexual dysfunction (SD) in both men and women. Erectile dysfunction (ED) has been considered the most important SD in men with DM. The prevalence of ED is approximately 3.5-fold higher in men with DM than in those without DM. Common risk factors for the development of DM and its complications include sedentary lifestyle, overweight/obesity and increased caloric consumption. Although lifestyle changes may help improve sexual function, specific treatments are often needed. This study aims to review the definition and prevalence of ED in DM, the impact of DM complications and DM treatment on ED and, finally, the current and emerging therapies for ED in patients with DM.

Abstract
Abstract
Background
Erectile dysfunction (ED) is common among ageing men because of associated underlying risk factors which are peculiar to this category of patients. Endothelial dysfunction and replacement of cavernosal smooth muscles by collagen fibres are common in older men, making them prone to ED. It is either vasogenic, neurogenic, hormonal, cavernosal or psychogenic in origin, but vasogenic causes are the commonest. This study was aimed at establishing vasogenic causes among patients being evaluated for ED using Doppler ultrasound as this category of ED is amenable to either medical and/or surgical treatment.
Methods
The study was conducted from July 2015 to January, 2017 at Federal Medical Centre Abuja. Nineteen consecutive patients with clinical diagnosis of erectile dysfunction were evaluated with Doppler ultrasound scan using a high-frequency linear array transducer. The penile scan was done before and after intracavernosal injection of 20 µg of Prostaglandin E1 (PGE1). B-mode scan of the penis was done prior to intracavernosal injection of PGE1, and the spectral waveforms as well as peak systolic velocity (PSV) of the CA were recorded at 5 min interval, from 5 to 50 min post-intracavernosal injection of PGE1, using angle of insoation ≤ 60°.
Results
The age range of the patients was fifty to sixty-six years (mean: 57.4 ± 4.3 years), while the PSV of CA varied between 21.4 and 104.4 cm/s (mean: 46.2 ± 19.2) among the entire patients, between 21.4 and 22.3 cm/s (mean: 21.9 ± 0.7) among patients with arteriogenic ED, and between 25.0 and 74.9 cm/s (mean: 45.0 ± 15.5) among those with venogenic ED. Arteriogenic ED was found in two patients (10.6%), while venogenic ED was observed in seven patients, which constituted 36.8% of the entire research participants. None had Peyronie’s disease, penile fracture, penile tumour or mixed arteriogenic and venogenic ED.
Conclusion
47.4% of the patients had vasogenic ED and venogenic ED was more common than arterioegenic ED in the age range considered. This categorization of ED with Doppler study is imperative before initiating therapy as treatment protocol for vasogenic ED is aetiologic specific.

Abstract
Erectile Dysfunction (ED) is the persistent inability to attain and maintain an erection sufficient to permit satisfactory sexual performance, causing tremendous effects on both patients and their partners. The pathophysiology of ED remains a labyrinth. The underlying mechanisms of ED may be vasculogenic, neurogenic, anatomical, hormonal, drug-induced and/or psychogenic. Neurogenic ED consists of a large cohort of ED, accounting for about 10% to 19% of all cases. Its diversity does not allow an in-depth clarification of all the underlying mechanisms nor a “one size fits all” therapeutical approach. In this review, we focus on neurogenic causes of ED, trying to elucidate the mechanisms that lie beneath it and how we manage these patients.

Abstract
Penile erection is a perfect example of microcirculation modulated by psychological factors and hormonal status. It is the result of a complex neurovascular process that involves the integrative synchronized action of vascular endothelium; smooth muscle; and psychological, neuronal, and hormonal systems. Therefore, the fine coordination of these events is essential to maintain penile flaccidity or allow erection; an alteration of these events leads to erectile dysfunction (ED). ED is defined as the consistent or recurrent inability of a man to attain and/or maintain a penile erection sufficient for sexual activity. A great boost to this research field was given by commercialization of phosphodiesterase-5 (PDE5) inhibitors. Indeed, following the discovery of sildenafil, research on the mechanisms underlying penile erection has had an enormous boost, and many preclinical and clinical papers have been published in the last 10 years. This review is structured to provide an overview of the mediators and peripheral mechanism(s) involved in penile function in men, the drugs used in therapy, and the future prospective in the management of ED. Indeed, 30% of patients affected by ED are classified as "nonresponders," and there is still an unmet need for therapeutic alternatives. A flowchart suggesting the guidelines for ED evaluation and the ED pharmacological treatment is also provided.

Abstract
No study has yet been done to evaluate topical alprostadil as a less invasive alternative vasoactive agent for Penile Dynamic Duplex Ultrasonography (PDDU) in the diagnosis of erectile dysfunction. The main aim of our study was to evaluate the usability and reliability of topical alprostadil for PDDU compared with standard intracavernous injection. A further objective was to determine the patients' preference between these two different approaches. During session A, patients received injection while during session B, they received topical alprostadil. Each patient underwent both sessions, 1 week apart from the other. A total of 80 patients were enrolled. After 20 min from drug administration, no significant difference was found between the two procedures in terms of peak systolic velocity and end-diastolic velocity, while Erection Hardness Score was significantly higher with injection. Patients reported less pain/discomfort during the procedure in case of topical alprostadil use and an overall preference towards this examination modality. Topical alprostadil could represent a usable and reliable alternative to intracavernous injection for PDDU, with less discomfort and greater preference by patients.

Abstract
OBJECTIVE This study has been carried out to assess the hardness of erection and the perception of improvement in erectile function with the treatments received during the last month. MATERIAL AND METHOD Descriptive, observational, multicenter, cross-sectional study carried out in 30 urology sites in Spain. Patients diagnosed of erectile dysfunction receiving treatment during at least the last month have been enrolled. Hardness of erection has been assessed with the erection hardness score and improvement perception has been estimated with the global assessment question. RESULTS A 63% of patients had a hardness of erection that was insufficient for penetration, but 75% of patients referred that their erectile function had improved with treatment. After adjustment for other factors, erection hardness score values were not significantly different among patients being treated with alprostadil topical cream, compared to patients being treated with the combination of phosphodiesterase 5 (PDE5) inhibitors plus alprostadil topical cream or with PDE5i other than sildenafil alone. However, patients treated with alprostadil topical cream had a significantly higher chance of referring an improvement in their erectile function compared to patients treated with PDE5i, despite the fact that they had received treatment for a shorter period of time. CONCLUSION Hardness of erection is just another factor of erectile function, but it is not the only one influencing improvement perception by patients.

Combination therapy for erectile dysfunction involving a PDE5 inhibitor and alprostadil. Int J Impot Res 2018; 30:203-208.

Abstract
The phosphodiesterase-5 inhibitors (PDE5Is) are the first-line treatment option for men with erectile dysfunction (ED), with alprostadil considered a second-line choice. Consideration has to be given to patients who fail these treatments and what their options are. This review evaluates the data on the combination of a PDE5I with alprostadil in patients who have previously failed therapy with either drug. A PubMed search was conducted and identified nine publications relating to combination treatment with alprostadil as intracavernosal, intraurethral or topical application. The results indicate that with all three formulations the combination therapy resulted in an improved outcome compared with either of the drugs as monotherapy. This was demonstrated by the increased total International Index of Erectile Function (IIEF) scores as well as IIEF erectile function domain scores. This finding was also valid for patients with post-prostatectomy ED. The associated side effects of the combined treatment did not result in treatment discontinuation. These findings suggest that combination therapy with a PDE5I and alprostadil might be considered a treatment option in patients who have previously had a poor response to either drug.

Abstract
Erectile dysfunction (ED) is a very common disorder with a deep impact on quality of life on both patients and partners. Several options are available for treating ED: oral pharmacotherapy with phosphodiesterase 5 (PDE5) inhibitors currently represents the first-line option for many patients with ED. Alprostadil, a prostaglandin, has been marketed for many years as a urethral stick and an intracavernous injection for the treatment of ED. It is now available in the form of a cream (Vitaros/Virirec), a noninvasive treatment which combines an active drug (alprostadil, a synthetic prostaglandin E1) with a skin enhancer improving its local absorption directly at the site of action. Alprostadil has a favourable pharmacodynamic profile and is poorly absorbed in systemic circulation, which makes it suitable in a lot of circumstances and results in a reduced risk of adverse effects (AEs). Systemic AEs are reported in only 3% of the treated population. Clinical efficacy has been demonstrated in both phase II and III trials, showing a global efficacy up to 83% with the 300 μg dose in patients with severe ED, significantly better than placebo. Its fast onset of action and lack of interactions with other drugs makes alprostadil cream a possible first-line therapeutic option for some patients with ED: individuals who are reluctant to take systemic treatments or have AEs, patients who do not respond, cannot tolerate, or do not accept PDE5 inhibitor therapy, and patients treated with nitrates. Therefore, this new treatment for ED can be offered to patients and could help address the needs unmet by other treatments.
