I am sure they just compounded with another chemical to make it into topical form.
According to WebMD, papaverine is used to treat, “Lack of Blood Supply to the Brain, and Peripheral Vascular Disease.” Also according to WebMD, ” Papaverine is a vasodilator. It works by relaxing the muscles in the blood vessels.”
I would use the cream if given the opportunity. It appears the study is taking place in China. I am sure the Chinese doctors in charge would allow someone to give it a try. Unfortunately, I don’t live in China.
Oddly enough, if you look online on some patent sites, there are exact directions on how to make topical papaverine cream specifically for ED. It is not easy.
I also would use the cream if I could get a hold of some. Maybe in time(sooner than later) it will be easily obtained; something along the lines of generic viagra/cialis.
