Market Surveillance Studies (MSS)

This activity involves the General European OMCL Network only.


Market Surveillance Studies (MSS) are carried out on commercialised medicines, particularly on those having a national marketing authorisation.

Products are tested according to a common protocol and on the basis of national sampling procedures.

To ensure that the same types of medicines are of comparable quality in the different member states, these studies are multilateral. Several are organised yearly. They look at different types of finished products for a given active substance and at herbal drugs.
Where a need is identified, the results of these studies could support revision of the relevant European Pharmacopoeia monographs and/or general chapters and methods.
