N NERVOUS SYSTEM
N02 ANALGESICS

This group comprises general analgesics and antipyretics.

All salicylic acid derivatives except combinations with corticosteroids (M01B) or opioids (N02AJ) are classified in N02BA - Salicylic acid and derivatives, as it is difficult to differentiate between the use of salicylates in rheumatic conditions and other therapeutic uses of salicylates.

All plain ibuprofen preparations are classified in M01A, even if they are only intended for use as pain relief.

There are a number of combined preparations, which contain analgesics and psycholeptics. These are classified in N02, as pain relief must be regarded as the main indication. Analgesics used for specific indications are classified in the respective ATC groups. E.g.:

A03D/
A03EA - Antispasmodic/psycholeptics/analgesic combinations
M01 - Antiinflammatory and antirheumatic products
M02A - Topical products for joint and muscular pain
M03 - Muscle relaxants

Lidocaine indicated for postherpetic pain is classified in N01BB.
