RESPIRATORY SYSTEM
Preparations for the treatment of diseases in the respiratory system, i.e. the nose,
throat and lungs, are classified in this group. Their therapeutic use and hence their
classification are based either on the active substance or on the route of
administration and formulation.
Corticosteroids and cromoglicate preparations formulated as nasal sprays, nasal
drops or nasal inhalants for topical treatment or prevention of allergic rhinitis are
classified in QR01A - Decongestants and other nasal preparations for topical use.
Corticosteroids for systemic use, however, would be classified in QH02 -
Corticosteroids for systemic use. Cromoglicate, formulated as a nebulizer and used
as an antiasthmatic, would be classified in QR03BC01.
Preparations for nasal administration for systemic use, e.g. oxytocin, are classified
in QH - Systemic hormonal preparations, excl. sex hormones and insulins.
The group QR includes, for example, opium alkaloids and derivates used as cough
suppressants (noscapine), acetylcysteine used a mucolytic, adrenergics for systemic
use indicated for bronchial asthma (clenbuterol) and antihistamines (piperazine
derivates) for systemic use, used in motion sickness.
The use of above-mentioned preparations in veterinary medicine is well
established, but for many of the remaining preparations within this group the
classification is based on the ATC classification for human medicine.
