Erectile Dysfunction


Oral medications are often the first line of treatment for erectile dysfunction. For most men who have trouble keeping an erection firm enough for sex (erectile dysfunction), these medications work well and cause few side effects. Sildenafil, Vardenafil, Tadalafil and Avanafil are oral medications that reverse erectile dysfunction by enhancing the effects of nitric oxide, a natural chemical body produces that relaxes muscles in the penis. This increases blood flow and allows erection in response to sexual stimulation.
