Effect of prescription medications on erectile dysfunction

Efficacy and safety of PDE5 inhibitors in middle-aged and old patients with and without hypogonadism

PURPOSE

Although several reviews have evaluated the use of PDE5 inhibitors (PDE5i) for treating erectile dysfunction (ED), their specific use in middle-aged and old patients has not been fully evaluated. Given that elderly patients with ED often have a complex combination of systemic and sexual health risk factors, the safety and efficacy of PDE5i in such a context are hereby reviewed.

MATERIALS AND METHODS

A thorough examination of existing literature has been conducted on PubMed.

RESULTS

PDE5i has good safety and efficacy, but the situation is more complex for patients with hypogonadism than those with normal testosterone levels, with reduced responsiveness to PDE5i. In this case, combination therapy with testosterone is recommended, safe and effective.

CONCLUSIONS

Eliminating or reducing reversible risk factors and controlling or slowing the development of irreversible factors is an important foundation for using PDE5i to treat ED in all patients, especially middle-aged and elderly ones.

Do oral antiviral drugs used in the treatment of chronic hepatitis B cause erectile dysfunction?

OBJECTIVE

The effect of antiviral drugs on the erectile dysfunction (ED) problem expressed by some patients using antiviral drugs due to chronic hepatitis B infection (HBV) was investigated.

METHODS

A total of 102 male patients receiving antiviral therapy for HBVinfection without any known non-cirrhotic and comorbid disease that may cause ED and whodon't use any drugs with an ED formation potential were analyzed through the InternationalIndex of Erectile Function test.

RESULTS

Among the patients admitted to the study, anxiety disorder was detected as 24.5% (n = 25) and depression as 46.1% (n = 47). 70.6% (n = 72) of the patients suffered ED. Severe ED was only detected in 3 (n = 2.9%) patients. ED was detected in 70.6% of the entecavir, 64.2% of tenofovir, and 80% of Tenofovir alafenamide users ( P  = 0.287). On the other hand, the logistics regression analysis revealed that the most important factors that increase the risk of ED are age (>55 age; RR: 2.66; P  < 0.001), and anxiety disorder (RR: 2.30; P  < 0.0001). The cumulative effect of antiviral drugs on ED was 5.7% (RR: 0.8; P  = 0.156).

CONCLUSION

We could not find any mounting evidence relating to the effect ofcommonly used antiviral drugs for hepatitis B causing ED. The incidence rate of ED on ourpatients was at a similar rate with population studies in the literature based on society. It is notappropriate to terminate antiviral therapy in hepatitis B for this reason.

A Scoping Review: Is Yoga an Effective Intervention for Erectile Dysfunction and Premature Ejaculation?

There is increasing concern among both healthcare professionals and the general public about the long-term effectiveness and possible adverse effects of medicines used to treat premature ejaculation (PE) and erectile dysfunction (ED). There is also a growing recognition of the advantages of incorporating alternative or traditional approaches into healthcare systems. Yoga is gaining popularity globally and has emerged as a viable adjunct and alternative to add value to patient care and prevention of illnesses, which requires further investigation. This scoping review aimed to explore the effects of yoga as an independent or adjunct intervention in treating ED and PE. In this review study, researchers conducted a systematic literature review from 2000 to 2023 as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Electronic databases of Scopus, Google Scholar, Web of Science, and PubMed were used for literature searches. Studies published in the English language on male individuals with ED and PE and those with comorbid stress, anxiety, and depression were also included. Studies on these sexual dysfunctions, comorbid with HIV/AIDS, and severe psychiatric conditions, i.e., schizophrenia, bipolar affective disorders, and substance dependence, except alcohol, were excluded. Ten studies out of the 2016 selected articles met the inclusion criteria and were included in the final analysis. The findings of this scoping review revealed that yoga interventions are more effective in managing PE and ED, with a greater emphasis on the former. Yoga is an effective, safe, and affordable approach recommended for managing erectile functions and PE. Men can improve their quality of life and regain confidence in sexual functioning by incorporating yoga into their routines. The study shows the potential benefits of yoga for both conditions, indicating the need for further robust studies in this area. Researchers advocate practising yoga under professional supervision for optimal safety and guidance.

Lower Urinary Tract Disorders as Adverse Drug Reactions-A Literature Review

A potential complication of pharmacotherapy for a given patient is the possibility of various side effects of drugs, which are manifested in many ways and constitute iatrogenic causes of diseases. Among the systemic side effects of drugs, there are also those involving the urinary tract, although these are less reported in the literature. The use of numerous drugs-especially of anticholinergics or drugs with anticholinergic potential, opioid analgesics, non-steroidal anti-inflammatory drugs, antidepressants, first-generation antipsychotics (classic neuroleptics) and selected cardiovascular drugs (beta-blockers, thiazides potassium-sparing diuretics, statins), as well as others-may increase the risk of developing urological disorders, such as urinary retention or incontinence, urinary tract infections, urolithiasis, erectile dysfunction in men and retroperitoneal fibrosis. The purpose of this paper is to characterise the abovementioned drug-induced disorders of the lower urinary tract on the basis of a non-systematic literature review.

Investigating self-reported efficacy of lifestyle medicine approaches to tackle erectile dysfunction: a cross-sectional eSurvey based study

BACKGROUND

Erectile dysfunction (ED) is the most common sexual dysfunction in men. Some types of ED are amenable to treatment using lifestyle medicine approaches with or without pharmacotherapy.

AIM

Investigate self-reported efficacy of lifestyle medicine approaches to tackle ED.

METHODS

A cross-sectional online survey of 1177 community dwelling adults explored the prevalence and methods used to tackle ED in the community setting. We examined differences between participants with and without ED. Variables associated with ED in univariable analyses were included in a multivariable logistic regression to identify variables independently associated with the condition.

OUTCOMES

Self-reported measure: perceived effectiveness of lifestyle medicine interventions to tackle ED.

RESULTS

Most respondents (76.5%) had experienced ED, and this was associated with having a long-term condition, taking anti-hypertensive medication, hypercholesterolaemia and obesity. Medication was the most common management strategy overall (65.9%), followed by stress management (43.5%) and weight loss (40.4%). Over half (53.9%) did not use any lifestyle modification strategies to tackle ED. Only 7.0% of ED sufferers received a mental health assessment and 29.2% received other tests (e.g., blood test, medical imaging) by GPs. Cardiovascular training was identified as the best rated strategy by its users (37.8%). Supplements (35.1%) and weight training/physical activity (32.6%) were also positively rated.

CLINICAL IMPLICATIONS

Structured education to general practitioners and community dwelling adults about the impact of lifestyle behaviour modification and how this could influence the appearance or trajectory of ED could help improve personal choice when tackling ED.

STRENGTHS AND LIMITATIONS

To our knowledge, this is the first study to collect eSurvey responses from community dwelling adults to gauge their reliance and perceived effectiveness of lifestyle medicine approaches to tackle ED. The principal limitation was the lack of follow-up, and not recording other information including lifestyle factors such as nutrition, smoking, and the use of alcohol and recreational drugs, which may have enabled a fuller exploration of the factors that could influence the primary outcome measures examined.

CONCLUSION

Despite the high prevalence of ED, there is not enough awareness in the community setting about effective and low-cost lifestyle medicine strategies, including cardiovascular training and the use of supplements and weight training, to help tackle this common condition.

Male Sexual Dysfunction

Male sexual dysfunction is a series of conditions, most notably including erectile dysfunction (ED), Peyronie's disease (PD), and premature ejaculation (PE), defined by impaired sexual functioning. The prevalence of male sexual dysfunction increases with age and is relatively high with greater than 50% of men aged 40 to 70 describing some degree of erectile dysfunction. Risk factors for male sexual dysfunction include age, diabetes mellitus (DM), cancer, stroke, hypertension, penile trauma, depression, anxiety, and disturbance in central serotonin neurotransmission and 5-HT postsynaptic receptor functioning. Sexual questionnaires including the International Index of Erectile Dysfunction, Sexual Health Inventory for Men, and the Premature Ejaculation Diagnostic Tool are useful in screening for these disorders. Focused history and physical can establish diagnoses. For a condition to be diagnosed as male sexual dysfunction, the patient or their partner must view their sexual functioning as impaired. Treatment of male sexual dysfunction is etiology dependent. For ED, first-line therapy is a phosphodiesterase-5 inhibitor or mental health care for psychogenic ED. More complicated cases may be treated with injections, surgery, or shockwave therapy. PD is either treated with medications for pain management, collagenase clostridium histolyticum injection, corpoplasty, plication, or shockwave therapy. PE may be treated behaviorally or with SSRIs as first line medication.

Medications Most Commonly Associated With Erectile Dysfunction: Evaluation of the Food and Drug Administration National Pharmacovigilance Database

Background

Erectile dysfunction (ED) is an adverse effect of many medications.

Aim

We used a national pharmacovigilance database to assess which medications had the highest reported frequency of ED.

Methods

The Food and Drug Administration Adverse Event Reporting System (FAERS) was queried to identify medications with the highest frequency of ED adverse event reports from 2010 to 2020. Phosphodiesterase-5 inhibitors and testosterone were excluded because these medications are often used as treatments for men with ED. The 20 medications with the highest frequency of ED were included in the disproportionality analysis.

Outcomes

Proportional Reporting Ratios (PRRs) and their 95% confidence intervals were calculated.

Results

The 20 medications accounted for 6,142 reports of ED. 5-α reductase inhibitors (5-ARIs) and neuropsychiatric medications accounted for 2,823 (46%) and 2,442 (40%) of these reports respectively. Seven medications showed significant levels of disproportionate reporting with finasteride and dutasteride having the highest PRRs: 110.03 (103.14–117.39) and 9.40 (7.83–11.05) respectively. The other medications are used in a wide variety of medical fields such as cardiology, dermatology, and immunology.

Clinical Implications

Physicians should be familiar with these medications and understand their respective mechanisms of action, so that they may counsel patients appropriately and improve their quality of life.

Strengths and Limitations

The strength of the study is its large sample size and that it captures pharmacologic trends on a national level. Quantitative and comparative “real-world” data is lacking for the most common medications associated with ED. The limitation is that the number of reported events does not establish causality and cannot be used to calculate ED incidence rates.

Conclusion

In a national pharmacovigilance database, 5-ARIs and neuropsychiatric medications had the highest reports of ED adverse effects. There were many other medications used in a variety of medical fields that were also associated with ED.

Contemporary cost-analysis comparison of direct-to-consumer vs. traditional prescriptions of phosphodiesterase-5 inhibitors

After a focused telehealth visit, patients can now access phosphodiesterase-5 inhibitor (PDE5 inhibitor) prescriptions through online direct-to-consumer (DTC) healthcare companies. This study seeks to quantify the cost of DTC PDE5 inhibitor treatment compared to a traditional physician visit and local pharmacy prescription. Two DTC companies, two compounding pharmacies with national reach, three online Canadian pharmacies, and sixteen American pharmacy chains were queried for prices of 90-day regimens of common PDE5 inhibitors. Prices for chains were determined using their publicly available price on GoodRx^® with coupon. Cost of physician visit was determined using 2020 Center for Medicare and Medicaid Services reimbursement for a level 3 new patient visit. For sildenafil 20 mg, a physician visit and local prescription cost a low of $125.45 compared to $144.35 for compounding, $169.34 for Canadian, and $195.00 for DTC. For sildenafil 100 mg, a physician visit and local prescription cost a low of $137.16 compared to $289.35 for compounding, $200.36 for Canadian, and $900.00 for DTC. For tadalafil 5 mg, a physician visit and local prescription cost a low of $125.80 compared to $169.35 for compounding, $195.34 for Canadian, and $720.00 for DTC. For tadalafil 20 mg, a physician visit and local prescription cost a low of $161.00 compared to $289.35 for compounding, $229.00 for Canadian, and $2880.00 for DTC. Thus, local pharmacies, in conjunction with online coupons, consistently provide a markedly less-expensive option for fulfillment of PDE5 inhibitor prescriptions than online DTC services.

Prevalence, Comorbidities, and Risk Factors of Erectile Dysfunction: Results from a Prospective Real-World Study in the United Kingdom

OBJECTIVES

Assessment of erectile dysfunction (ED) burden could improve health outcomes associated with underlying cardiometabolic and psychological causes of ED. This study provided updated real-world evidence (RWE) on ED epidemiology and quantified healthcare resource utilization (HCRU) and health-related quality of life (HRQoL) burden among men with ED in the UK.

METHODS

This cross-sectional, prospective real-world evidence study was conducted via a self-reported Internet survey in 2018 in the UK general population. Prevalence of ED was estimated; HCRU and HRQoL were compared between men with ED versus without ED via bivariate analysis.

RESULTS

Of 12,490 men included, 41.5% reported ED; 7.5% of men reported severe ED; ED was most prevalent in Wales (44.3%). Men with ED were older (54.1 ± 14.5 vs. 46.8 ± 14.1 years) and often reported modifiable lifestyle risk factors, including smoking (32.8% vs. 26.3%), drinking alcohol (76.1% vs. 71.0%), not exercising (21.7% vs. 19.4%), and being overweight or obese (64.9% vs. 54.6%). Additionally, men with ED more often reported ≥1 comorbid chronic conditions (73.7% vs. 47.7%), including hypertension (31.8% vs. 16.3%), hyperlipidemia (27.6% vs. 14.0%), depression (24.3% vs. 14.6%), anxiety (23.3% vs. 16.6%), and diabetes (15.9% vs. 6.1%) versus men without ED (all, p < 0.001). Nearly half of men with ED (45.3%) were not undergoing treatment for cardiometabolic or psychological comorbidities. Furthermore, men with ED more often reported ≥1 visit to physicians/nurse practitioners and pharmacists in the past year and had significantly lower SEAR total and domain scores than men without ED (all, p < 0.001).

CONCLUSION

ED was highly prevalent in the UK affecting over a quarter of younger men. Cardiometabolic and psychological conditions were common among men with ED and often remained untreated. Higher proportions of modifiable lifestyle risk factors observed among men with ED present an opportunity for healthcare providers to help mitigate the risk of cardiometabolic diseases and incidence of ED.

Pharmacological treatment and inappropriate prescriptions for patients with erectile dysfunction

Background Erectile dysfunction is associated with old age, some morbidities and the use of certain medications. Objective To identify the treatments and drugs related to worsening sexual activity in patients with erectile dysfunction. Setting Patients diagnosed with erectile dysfunction during 2018. Methods This cross-sectional study of a population database identified all drug prescriptions of patients with erectile dysfunction during 2018. Main outcome measure The identification of other comorbidities and potentially inappropriate drugs that could worsen erectile dysfunction. Results A total of 2999 patients with erectile dysfunction (mean age 59.6 ± 12.1 years) were identified. A total of 88.2% received pharmacological treatment for erectile dysfunction, mainly tadalafil (70.5%). A total of 47.6% of all patients received at least one medication associated with worsening erectile dysfunction, especially hydrochlorothiazide (17.0%), metoprolol (7.9%) and sertraline (6.7%). Residing in Cali (OR 1.86; 95% CI 1.52-22.27) or Bucaramanga (OR 2.23; 95% CI 1.39-33.58), having 3 or more chronic comorbidities (OR 1.52; 95% CI 1.04-2.24) and presenting psychiatric (OR 5.5; 95% CI 3.70-8.17), cardiovascular (OR 3.48; 95% CI 2.79-4.33), genitourinary (OR 1.31; 95% CI 1.05-1.64) pathologies or chronic kidney failure (OR 1.84; 95% CI 1.18-2.21) elevated the probability of receiving these prescriptions. Conclusions The pharmacological treatment of erectile dysfunction was in accordance with the recommendations of clinical practice guidelines, but the high proportion of potentially inappropriate prescriptions makes it necessary to promote educational and pharmacovigilance strategies that improve the prescription habits of physicians involved in caring for this group of patients.
