N02B
OTHER ANALGESICS AND ANTIPYRETICS
ATC/DDD code N02B for OTHER ANALGESICS AND ANTIPYRETICS
See general considerations under N02.
Combinations with opioid analgesics should be classified in N02A at separate 5th levels, using the corresponding 50-series (combinations excl. psycholeptics) or the 70-series (combinations with psycholeptics)
or in N02AG - Opioids in combination with antispasmodics.
Combinations with codeine or dihydrocodeine are, however, classified in this group if the codeine or dihydrocodeine content per unit dose is less than 20 mg. Otherwise these combinations are classified in N02AA.
Combinations with muscle relaxants are classified in M03B.
Combined preparations which contain more than one analgesic, should be classified by using the following ranking:
1. Phenacetin 2. Bucetin 3. Dipyrocetyl
4. Paracetamol
5. Acetylsalicylic acid
6. Phenazone
7. Salicylamide
8. Propyphenazone
This means that a product containing paracetamol and phenazone should be classified in N02BE51 - paracetamol, combinations excl.
psycholeptics and not in N02BB51 - phenazone, combinations excl.
psycholeptics.
Dextropropoxyphene plain, and in combination with other analgesics, is classified in N02AC.
Cold preparations with therapeutic levels of analgesics are classified in this group at separate 5th levels by using the 50-series.
Preparations are subdivided on 4th levels according to chemical structure.
Combinations with ascorbic acid (i.e. 50 mg or more per unit dose) are classified at separate 5th levels using the corresponding 50-series.
Products containing less than 50 mg per unit dose are classified at the plain level of the analgesic component.
The DDDs are based on approved dose recommendations.
When establishing DDDs for combination products in the 50-
series, all analgesic components are taken into consideration if the amount of each component is a therapeutic dose.
The DDD expressed in UD, should normally not exceed the approved dose recommendations for any of the components. See list of DDDs for combinations products, www.whocc.no.
For combination products with codeine (i.e. less than 20 mg per unit dose), the amount of codeine is not taken into account when assigning a DDD.
