Codeine Extraction from Perduretas

[mrbigsexy]

I was wondering if anybody had any specific information on codeine extraction from Perduretas specifically. If anybody is familiar with them, they contain only codeine as the active ingredient. So you don't have to deal with APAP solubility. Also, most of the other ingredients and binders seem to be fairly insoluble (It uses arabic gum, or something like that as the time release mechanism).

Anyway, does anybody have any specific experience with Perduretas? It should be simpler, if not, easier than the tylenol extraction, but I just wanted to check with others for advice and any other unforseen problems.
