Opioids Is it possible to separate codeine from chlorpheniramine and pseudoephedrine?

OK.

This is a weird one.

Here in my country I've a lot of these codeine syrups, but they come with monstrous doses of pseudoephedrine and chlorpheniramine. So I was wondering, if maybe something like a cold water extraction (CWE) could be done? Or would it be too complicated process that would not be worth it?

Spoiler

For non-bilinguals: each teaspoon of syrup (5 mL) brings:

- Pseudoephedrine = 7.5 mg
- Chlorpheniramine = 0.75 mg
- Codeine = 10 mg

Basically, it brings a lot of shit.
