Zebra: I believe your estimate of Viagra's effectiveness (30%) is understated.

A summary of the Viagra Phase III studies (being reviewed by the FDA and published in brokers' reports) indicate an efficacy of 48% to 81% depending of the cause of ED. The spinal studies were particularly impressive (75% efficacy for Viagra versus 0% for placebo). Click here for my prior post on this subject. www3.techstocks.com

Here's my basic theory why a systemic ED drug may be able to target the penis and not significantly effect other parts of the body:

The chemical reactions and enzymes needed to create and reduce an erection are centered almost totally in the penis. If they weren't, the ears, nose, fingers, and toes of males would become erect when sexually stimulated. Not a pretty sight! If you found an oral agent that focused on the specific enzymes that impact erections and was safe, it would be a major advance in the treatment of erectile dysfunction. Only time and widespread usage will tell if Viagra is that agent.

How will the availability of Viagra effect MUSE? ED is too complex for any one agent to be 100% effective or accepted totally by physicians. Best guess: although some initial usage will be lost to Viagra, there will a greatly expanding ED market for MUSE to develop. Accordingly, it is very probable that sales of MUSE will increase with the introduction of Viagra.
