Extracting codeine when mannitol is present

[weedar]

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
