N01BX Other local anesthetics
206
Capsaicin products indicated for the symptomatic treatment of
peripheral neuropathic pain (incl. postherpetic neuralgia) are classified
in N01BX. See also M02AB.
N02 ANALGESICS
This group comprises general analgesics and antipyretics.
All salicylic acid derivatives except combinations with corticosteroids
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 ibuprofen preparations are classified in M01A, even if they are only
intended for use as pain relief.
Salicylic acid derivatives in combination with corticosteroids are
classified in M01B.
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
See comments to these groups.
Lidocaine indicated for postherpetic pain is classified in N01BB.
