Alprostadil
erectile dysfunction
"I'm 66,  in good health except for high blood pressure, and have been using Edex for almost 4 years now at the lowest dosage. It works most of the time,  giving a fast erection (in 5 minutes or less) and a reasonably long-lasting one.  This isn't as effective (neither as hard nor as long-lasting) as the "cocktails" found at the various "men's medical clinics"  you hear advertised on the radio, but if it's covered by insurance it's far less expensive.  Sometimes there is a lingering pain in the penis for several hours afterwards with the alprostadil,  but the results are worth it!"
