Abstract:
ED treatment has changed fundamentally since phosphodiesterase type 5 inhibitor (PDE5-I) came into clinical use. There are three kinds of PDE5-I available at present, Sildenafil, Vardenafil and Tadalafil. Tadalafil distinguishes from the other two by its uniquely long half-life, which lasts 17.5h, which a pharmacodynamic duration of 36h and not influenced by food and alcohol. Thus it may enable ED patients to accomplish a spontaneous intercourse without the need of prior preparation without, which can boost their confidence and self-esteem and, the most important, improve the relationship with their partner. To know patient preference counts quite a lot in optimizing the medication ED treatment.
