The prescribing increased rapidly from 2013–2017. The highest yearly increase occurred from 2014–2015, which showed a 42.1% increase. A 5.8% yearly increase in the rate of prescription was observed between 2017 and 2018. A 0.5% increase in the rate of prescribing between 2018 and 2019 was observed, suggesting modest impact of reclassification on the prescribing practices. The number of items prescribed per 1000 men were 124.2 and 125.8 in 2018 and 2019, respectively. The spending on primary care prescriptions for ED decreased by 71.0% from £77.4 million in 2009 to £22.4 million in 2019. The spending on sildenafil decreased by 90% and tadalafil decreased by 75%. The biggest decreases were seen after 2014 for sildenafil and 2018 for tadalafil (Figure 1).

Mechanism of action

Promotion of sildenafil by pharmaceutical industries since being made available over the counter for pharmacy sales could have raised awareness of ED among the general public. Higher rate of prescribing in deprived regions offers opportunity for monitoring of linked health conditions such as CVD and diabetes. The most deprived regions consistently showed higher rates of prescriptions for ED drugs.

In 2019 there were 190.4 items prescribed per 1000 men of all ED drugs in the most deprived region. This figure was approximately 21.0% higher compared with the data from the least deprived regions, where a total of 150.5 items were prescribed per 1000 men. In the most deprived regions, the yearly increases in prescription items were 9.0% in 2016, 4.5% in 2017, and 4.4% and 5.0% in 2018 and 2019, respectively. An overall 24.9% increase in prescription items was observed from 2015–2019. In the least deprived region, the rate of increase in the number of prescriptions was 38.9% during the same period (Figure 2). A wide variation in the rate of prescribing across the six English regions were observed. The North East and the North West regions had approximately 50% higher rates of prescribing compared with London. Rates of prescribing were 15.9, 15.3, and 10.3 items per 1000 men each month, respectively, in these regions (Figure 3). The aim of this study was to investigate the trend in prescribing of drugs for ED in primary care settings in England and to assess the impact of deprivation, regional demography, and legal reclassification of sildenafil on prescribing practices of ED drugs.

Feeling Low?

These include: CVDs such as hypertension, coronary artery disease, peripheral vasculopathy; endocrine disorders such as diabetes, metabolic syndrome, and hyperthyroidisim; as well as assessment of psychogenic risk factors and medication-induced ED.2 Prescribers should be aware of the wider organic, psychogenic nature and linked risk factors of ED including diabetes, vascular disorders, and mental health conditions. The cause of cialis street price ED needs to be established before treatment can commence and patients should be referred to specialist clinics where appropriate. Guidelines recommend that a physical examination, including genitourinary, endocrine, vascular, and neurological systems, is undertaken. This can reveal any unsuspected diagnoses, such as Peyronie’s disease, pre-malignant or malignant genital lesions, prostatic enlargement or irregularity or nodularity, or signs and symptoms suggesting hypogonadism.2,3 It is, however, unclear how often patients are screened for the red-flag symptoms. Long-term safety outcomes of PDE-5Is are not understood.

Manufacturers’ Strategies

Prescribers should, therefore, reassess the continuous use of these drugs on a periodic basis.22,23 Reclassification to allow ‘pharmacy-only’ supply of drugs to free-up GP time and resources have faced successes and barriers in the past.24–26 For example, reclassification of drugs such as chloramphenicol eye products, mild steroids, and antifungal products have been positively received by patients, GPs, and pharmacists. However, reclassified pharmacy version of simvastatin was not adopted in practice to the same extent.24 Research on community pharmacist and patient perspectives on the need, supply, and aspects of risk assessments and referrals are warranted. GPs and patient experiences of access to sildenafil from pharmacy also need to be further explored. Results of this study suggest that more men are being screened for, or seeking help with, ED. The two-fold observed increase in the population adjusted rate of prescriptions over the past 10 years is less likely to be accounted for by other factors. There was a persistent increase in the rate of prescribing for treatment of ED in men between 2009 and 2019 in English primary care. Sildenafil remained the most frequently prescribed medication out of the two super cialis drugs of choice. A strong link between deprivation and prescribing trends were observed across all data points. These can be linked to higher prevalence of risk factors of ED, such as cardiovascular and mental health conditions, with deprivation.14 A north–south divide was observed in the rate of prescriptions, with higher prescribing rates observed in the northern regions of England compared with London and the southern regions.

Which lasts longer: Cialis or Viagra?

Deprivation data were based on CCG level and individual practice level variations were not accounted for. This study only included NHS prescription data and private prescriptions were not accounted for. Only two PDE-5Is were included, sildenafil and tadalafil, as the authors' observations suggested that the rest of the PED-5Is accounted for negligible volume of prescribing and, hence, did not impact on the trend analysis. Similarly, community and online pharmacy sales of over-the-counter sildenafil were not included in the trend analysis. Some patients may avoid perceived order cialis super force embarrassment and confidentiality issues in face-to-face clinical consultations in primary care and community pharmacy16 by accessing medicines through online sources.

How do Cialis and Viagra affect sexual performance?

Other available treatments for ED, including vacuum-pump treatment and psychosexual therapies, were not included in the study. In addition, prevalence data of ED over time were considered for this study. The segmented regression for different policy changes (for example, sildenafil patent expiry in June 2013, tadalafil patent expiry in November 2017, and reclassification of sildenafil from prescription medicine to pharmacy medicine in March 2018) could not be performed owing to: a) absence of monthly prescribing and spending data (access was restricted to annual level for historical data prior to 2015); and b) inadequate time-points before and after different policy changes needed to conduct segmented regression analysis.17 There is a lack of literature on the prescribing and management of ED in primary care. Previous studies have reported that many men do not seek help with sexual problems to avoid perceived embarrassment for themselves and their doctors.18,19 The observed increasing trend in the rate of prescriptions may have been contributed by various factors. These include inclusion of ED assessment for men with diabetes in the Quality and Outcomes Framework (QOF) since 2013–2014.20 The QOF required opportunistic screening, advice and assessment of contributory factors, and treatment options for ED in patients with diabetes in primary care.

How Medication Helps

In addition, media, including social media, may have contributed to increased knowledge and awareness of the condition among members of the general public given the licensing of newer PDE-5Is in recent years. The study shows that the introduction of generic versions of both sildenafil in 2013 and tadalafil in 2017 reduced overall spending on drugs used for ED. The expiry of the patent on sildenafil in June 2013 allowed the NHS to purchase generic sildenafil from other pharmaceutical companies for a competitive price, subsequently reducing the price per item from £31.31 in 2012 to £2.53 in 2014.11 This also allowed sildenafil to be removed from the Selected List Scheme, which restricted prescriptions of certain drugs in May 2014, allowing more men access to the medicine on the NHS, which potentially increased the number of items prescribed.21 The patent on tadalafil also expired in November 2017, leading to a 49% decrease in cost per item from £49.40 in 2017 to £25.12 in 2018. The data suggest that more men are seeking help or being assessed for ED in primary care. The increased presentations and, hence, prescribing for EDs allows further opportunities to screen for the associated risk factors for ED. While some of the regional variations are explained by the differences in deprivation level, London’s younger population compared with the rest of the country15 could explain low ED prevalence and the observed low prescribing for ED. In addition, patient behaviours around use of online sources for access to sildenafil may be different across various geographical regions. Data showed that reclassification of sildenafil to a pharmacy medicine from ‘prescription-only' medicine had modest impact on the trend of prescribing. It could be assumed that the reclassification of sildenafil would lead to a decrease in the number of items prescribed as people would be able to get their medicine directly from the pharmacy instead of needing to go to the doctors and wait for an appointment.

It is important to note, however, that the pharmacy version of sildenafil costs approximately £20 for a pack of four tablets (as of April 2020) whereas the generic sildenafil prescriptions from a GP only costs £9 for the same number of tablets. The higher cost of the pharmacy version of the medicine compared with the prescription cost may dissuade patients from using pharmacy for accessing sildenafil. In addition, confidentiality and privacy have been cited as barriers to utilisation of sexual health services from pharmacy.16 The lack of long-term monitoring and follow-up in pharmacy settings may also discourage many patients from accessing the pharmacy version of sildenafil. This project included data from very large routinely collected datasets covering all primary care prescriptions in England. Deprivation data were based on CCG level and individual practice level variations were not accounted for. This study only included NHS prescription data and private prescriptions were not accounted for. Only two PDE-5Is were included, sildenafil and tadalafil, as the authors' observations suggested that the rest of the PED-5Is accounted for negligible volume of prescribing and, hence, did not impact on the trend analysis.

What Are the Current Market Dynamics for Tadalafil?

The North East and the North West regions had approximately 50% higher rates of prescribing compared with London.
