QN02B
OTHER ANALGESICS AND ANTIPYRETICS
See general considerations under QN02.
Combinations with opioid analgesics should be classified in QN02A or in

2. Bucetin
3. Dipyrocetyl
4. Paracetamol

classified in QN02BE51 - paracetamol, combinations excluding psycholeptics and
not in QN02BB51 - phenazone, combinations excluding psycholeptics.
Dextropropoxyphene, plain and in combination with other analgesics, is classified
in QN02AC - diphenylpropylamine derivatives.
