Based on the impending shift in the oral PDE5 inhibitor market from brand to generic products, patients and providers will have more freedom of choice, and cost will be a lesser consideration. Although multiple reports suggest general equivalency of efficacy and safety between the four major PDE5 inhibitors, tadalafil with optimal use has been suggested to be preferable, providing increased efficacy in the ability to insert and the successful completion of intercourse. AEs, onset and duration of action, administration considerations, precautions, and cost are all key factors in individualizing therapy.

Further studies comparing these agents are needed to distinguish the possible benefits of each, particularly in specific subsets of patients.
All PDE5 inhibitors allow for flexibility in prescribing and patient preference based on individual response and need. Specific characteristics of each agent (cost, ease of use, and adverse effects) should be used to guide appropriate treatment.
