Definition of erectile dysfunction

Erectile dysfunction is defined as a persistent inability to achieve or maintain an erection sufficient for sexual intercourse, occurring in at least three quarters of sexual encounters. It has a significant impact on the individual or their partner.

Overview from a medical expert

Dr. Antoine Faix, a urologist-andrologist and president of the French Association of Urology, explains that the management of erectile dysfunction includes hygienic-dietary measures, treatment of related health conditions, psychosexual support, and pharmacological treatment. The first-line treatment involves IPDE5s, a class of medications.

Choosing the right IPDE5 medication

The choice of IPDE5 medication depends on several factors, including cost, as these drugs are not covered by insurance. Sildenafil, tadalafil, and vardenafil are available as generics, while avanafil is not. Other considerations include the speed and duration of action, as well as patient preferences.

Tailoring treatment to lifestyle

The timing and frequency of sexual activity influence the choice of IPDE5. For couples with planned encounters, occasional use of IPDE5 after specific events may be suitable. For men with more spontaneous activity, a daily dose of 5 mg tadalafil is often recommended. Some doctors prescribe two options to allow the patient to choose based on their needs.

Form and side effects of IPDE5s

The form of the medication can affect patient comfort, with orodispersible tablets being easier and more discreet for some. Side effects vary by molecule, with tadalafil more likely to cause digestive or muscle issues, while sildenafil and vardenafil are more commonly associated with headaches and facial flushing.

Important considerations for pharmacists

Pharmacists should check for contraindications like recent cardiovascular events or uncontrolled hypertension and be cautious of interactions with certain medications. They should also emphasize the importance of sexual stimulation for the drugs to work and clarify the timing of administration, especially for tadalafil.

When to reassess treatment effectiveness

IPDE5s are typically considered ineffective after 4 to 6 unsuccessful attempts. However, if a patient experiences significant distress or avoidance of sexual encounters after three failures, referral to a doctor may be appropriate.
