We report on 64 patients who did not achieve erections adequate for satisfactory sexual intercourse from among a total of 243 patients who were prescribed PDE5 inhibitors for erectile dysfunction (ED). Intracavernous injection (ICI) of PGE was performed in this non-responder group. An ICI of 20 or 40 mcg of PGE1 in 1 ml saline was performed and the responses evaluated. Forty-nine out of 64 (77 percent ) cases responded to 20 mcg of PGE1. Forty mcg of PGE was injected into the 15 non-responding cases, and 9 patients responded favorably. The overall effective rate was 58/64 (91 percent ). No major adverse effects were observed.
