National Legislation


The conduct of clinical trials on medicines for human use is governed by Law no. 21/2014 of 16 April that implements Directive 2001/20/EC of the European Parliament and of the Council of 4 April in Portuguese legislation.

In addition to the above legislation there are a series of guidelines covering various matters related to clinical trials which can be found in Volume X of Eudralex.

To that end, and as part of the harmonised European system, the conduct of clinical trials in Portugal requires authorisation from INFARMED, I.P. and a prior favorable opinion from CEIC (Ethics Committee for Clinical Research).
