Rectal Methylphenidate Bioavailability

I'm curious

sincerity
oral = 30%
nasal = 50-60%
iv = 100%
rectal = ????

You really like your speedy ADHD medications, don't you? lol

a cursory search of google didn't lead me to any studies or any information consolidating any percentages but i would assume it's considerably high given the anecdotes i've read.

if anyone has anything conclusive to the rectal BA of the drug please pm one of us mods and we can reopen the thread and address it in the BA Thread that's in OD (the link is found in the directory link in my signature).
