Tadalafil is a medication used to treat male sexual performance problems such as erectile dysfunction and enlarged prostate. It works by increasing blood flow to the genital area, thus helping to get and maintain erections. Sildenafil is a similar medication in the same class but works faster than tadalafil for ED.

Tadalafil is not a prostaglandin inhibitor like other agents that are used to treat Erectile Dysfunctions and unlike Sildenafil, it does not lead to the development of visual disturbances and sensory conditions. When Tadalafil is used for the treatment of ED, its duration of action can last to up to 36 hours which is longer than the action span of both Sildenafil and Vardenafil. Since PDE5 inhibitors only facilitate an erection as a response to sexual stimulation, Tadalafil’s longer duration of action generates a more spontaneous sexual stimulation and sexual action. Tadalafil is prefered if ED has become chronic. In most cases Tadalafil is a better candidate the other medications of similar class.
