After one or more equivalent medicines of a medicine reimbursed by the SSN, whose patent protection has lapsed, have been authorized, AIFA includes both the original medicine and its equivalents in a list, which is up-dated monthly, called the "transparency list". It is available on the AIFA web site,
http://www.agenziafarmaco.it/section8983.html.
In this list the original medicine and its equivalents are listed together, with their corresponding reference price. The medicines grouped together on the transparency list can be substituted. This list therefore attests the fact that the listed medicines are considered equivalent and, as a consequence, sanctions their substitution.
