Choice of medications for the treatment of ED
There are a variety of medications available for the treatment of ED. The choice of medication will depend on the cause of the problem and on the individual's response to different types of medication.

The most common type of medication for treating ED is phosphodiesterase inhibitors, or PDE inhibitors. These medications work by increasing blood flow to the penis, which helps to produce an erection. PDE inhibitors include sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra).
All three medications are effective in treating ED, but they may not be equally effective in every person. Some people find that one particular drug works better than another, while others have no preference.
If one type of PDE inhibitor doesn't work well or causes side effects, another type can be tried instead.
