FURAGUNO AND FURAZADROL ARE THESE EXACTLY THE SAME?

[samva777]

I am curious are these exactly the same compounds or is there a slight difference I am not a chemistry major but it looks like on FURAZADROL at the end of the chemical nomenclature it has an ETHER added I think this is for absorbtion. Anyway does anyone have experence with both of these compounds and if so which is better or am I wrong and they are exactly the same.
