Background: Numerous pathways can lead to erectile dysfunction (ED) in patients, with some patients having multiple causes. Regardless of the etiology, ED has been successfully treated in many patients with the advent of oral phosphodiesterase-5 inhibitors (PDE5Is). With the release of avanafil, there are currently four PDE5I options available, and choosing between them should be based on patient-specific considerations and preferences.
Objective: To review the treatment of ED with PDE5Is, taking into account the effectiveness, safety, and patient satisfaction of these agents, as well as avanafil’s place in therapy.
Methods: A PubMed search was completed to find articles published in English studying patient satisfaction and adherence to ED medication. Additional searches looked specifically for any data regarding the use of avanafil.
Results: ED is effectively treated in most patients with PDE5Is, with the most common side effects from the medications being headache, flushing, and visual disturbances. Patients have identified many different factors, such as efficacy, side effects, duration of action, and daily use, in determining overall satisfaction and the right medication for them. While avanafil does not have any patient satisfaction trials to date, it has been proven to be a safe and effective treatment for ED with possibly the fastest onset of action and fewer visual disturbances than its competitors.
Conclusion: Avanafil along with the other PDE5Is has shown to be a safe and effective oral treatment for ED, with avanafil’s possible place in therapy for patients who want an on-demand option or as an alternative in patients who experience visual disturbances with the other agents.
