>>...how practical is it to use a drug like secretin for ADHD? << Sorry, rkrw, I meant to say a Secretin trial is underway in OCD (Obsessive Compulsive Disorder), not ADHD. Please see <a href='read_msg.asp?message_id=4127301'>#msg-4127301</a>. My opinion about this trial’s likely outcome is as stated. I think Secretin is just a placebo, and I doubt it will truly work in any CNS indication.
