Guidelines for ATC classification and DDD assignment - WHOCC

S01CB Corticosteroids/antiinfectives/mydriatics in combination
250
This group is built up as S01CA.
S01CC Antiinflammatory agents, non-steroids and antiinfectives in combination
S01E ANTIGLAUCOMA PREPARATIONS AND MIOTICS
This group comprises preparations for local and systemic treatment of
glaucoma.
Drugs used for producing miosis are classified in this group, even if the
main indication is not glaucoma.
The DDDs are based on single dose (or single package) and
administration frequencies. A single dose is defined as two eye
drops (one in each eye) corresponding to 0.1 ml. For eye drops
administered once daily the DDD is 0.1 ml, for eye drops
administered twice daily the DDD is 0.2 ml, etc. For single use
packages one dose is the volume of one package. This also applies
for combinations. In eye ointments one dose corresponds to about
10 mm (20 mg) per eye thus corresponding to 40 mg for both eyes.
S01EA Sympathomimetics in glaucoma therapy
Preparations containing parasympathomimetics in combination with
epinephrine, are classified in S01EB.
S01EB Parasympathomimetics
Combinations with beta blocking agents are classified in S01ED.
The DDD for pilocarpine lamellas has been obtained by dividing
two lamellas by seven days (the recommended dose is 1 lamella/
eye/week).
S01EC Carbonic anhydrase inhibitors
The DDDs are based on the average recommended doses in the
treatment of chronic glaucoma.
