Several PDE5i are available (sildenafil, tadalafil, vardenafil, avanafil), each with distinct pharmacokinetic properties and side effect profiles, along with different formulations (film-coated, oro-dispersible film) and a wide range of dosages [6], allowing for a tailored treatment strategy. Nonetheless, most men with ED discontinue therapy within the first year due to medical and psychosocial factors (e.g., cost, relationship issues, concerns about loss of spontaneity in intercourse) [8].
