Guidelines for ATC classification and DDD assignment - WHOCC

J01 ANTIBACTERIALS FOR SYSTEMIC USE
This group comprises antibacterials for systemic use, except antimycobacterials,
which are classified in J04. The antibacterials are
classified according to their mode of action and chemistry.
Combinations of two or more systemic antibacterials from different third
levels are classified in J01R, except combinations of sulfonamides and
trimethoprim, which are classified at a separate 4th level, J01EE.
Combinations of antibacterials with other drugs, including local
anesthetics or vitamins, are classified at separate 5th levels in the
respective antibacterial group by using the 50-series. Common cold
preparations containing minimal amounts of antibacterials are classified
in R05X.
Inhaled antiinfectives are classified here based on the fact that
preparations for inhalation can not be separated from preparations for
injection.
J01A TETRACYCLINES
J01AA Tetracyclines
This group comprises tetracycline antibacterials inhibiting the bacterial
protein synthesis through binding to the 30-S part of ribosomes.
The tetracyclines have different DDDs due to kinetic differences.
The use of tetracyclines in long-term, low dose treatment of acne is
not taken into account in the assignment of DDDs.
J01B AMPHENICOLS
J01BA Amphenicols
This group comprises amphenicol antibacterials inhibiting the bacterial
protein synthesis.
Thiamphenicol acetylcysteinate glycinate for inhalation is classified in
J01BA52.
