Extracting codeine when mannitol is present
« on: October 15, 2004, 05:33:00 AM »
I've read about the cold-water extraction of codeine, to
remove paracetamol - but I discovered some pills containing:
400mg paracetamol
30mg codeine
mannitol q.s.

My question is as follows: Would it bee necessary to
remove the mannitol, seeing as it is a diuretic, or could
one do a normal cold-water extraction? Is the mannitol
a problem, if so how does one easily remove it? :)

try the extraction like you normaly would then compare the actual yield to the theroretical yield and see if thier is any excess  thats the best i could sugest sorry
