QS
SENSORY ORGANS
Preparations for topical treatment of diseases in the sensory organs, i.e. the eyes and
the ears, are classified in this group. The therapeutic main groups are classified as
ophthalmologicals, group QS01, and otologicals, group QS02. Preparations used to
treat both eye and ear diseases are classified in group QS03.
A formulation approved both for use in the eye/ear is classified in S03, while
formulations only licensed for use in the eye or the ear are classified in S01 and
S02, respectively.
The therapeutic subgroups include, for example, antiinfectives, antiinflammatory
agents, miotics, mydriatics, antiglaucoma preparations, surgical aids (for eyes) and
local anesthetics. Some of the preparations classified as surgical aids, e.g.
QS01KA - Viscoelastic substances, might also be classified as medical devices.
Systemic preparations for treatment of glaucoma is classified in QS01E.
