Frequently asked questions
What does ATC code C03 mean?
C03 stands for Diuretics in the WHO ATC system. The code says nothing about the Swiss authorisation or dispensing category, only about the substance class.
How many medicines with ATC C03 are authorised in Switzerland?
30 medicines, data as of 01 September 2026. The count covers authorisations, not pack sizes or strengths.
Where is the ATC code of a medicine stated?
The Swissmedic export records the ATC code per pack size, and the product information on swissmedicinfo.ch lists it. Not every medicine has an ATC code: homeopathic products and some diagnostics do not.
