Codeine facts for kids
Codeine or methylmorphine is an opiate used for its analgesic properties. It is also used to treat coughing and diarrhea. It is marketed as the salts codeine sulfate and codeine phosphate. Codeine hydrochloride is more commonly marketed in continental Europe and other regions.
Codeine is an alkaloid found in opium in concentrations ranging from 0.3 to 3.0 percent. Codeine can be extracted from opium. Today, most codeine is synthesized from morphine through the process of O-methylation.
Uses
Codeine is used to treat the following:
- Cough, though its efficacy in low dose over the counter formulations has been disputed.
- Diarrhea
- Moderate to severe pain
- Irritable bowel syndrome
Compound analgesics
Codeine is often marketed as drugs in combination with paracetamol (acetaminophen) as co-codamol (best known in North America as Tylenol 3). Research has shown the combination to be very much more effective than paracetamol, and much less addictive that pure codeine.
There are similar combinations with aspirin as co-codaprin or with ibuprofen. These combinations provide greater pain relief than either agent alone. Drug synergy is an important principle.
