OK, I didn't do the homework (that's our job but many of us lay it off on you), but relied on your last mention here of NN1731, which styled it "short-acting" vice "fast-acting": >NVO has scrapped NovoSeven in favor of NN1731 (a short-acting FVIIa analogue)< <a href="http://investorshub.advfn.com/boards/read_msg.aspx?message_id=28922135" target="_blank">http://investorshub.advfn.com/boards/read_msg.aspx?message_id=28922135</a> It's a good thing though that we get reminded that rapidity of onset and duration of effect are completely separate issues. <!--Beg_Sig-->
