From BioSim we positively value the mere initiative of the Permanent Pharmacy Commission of the Interterritorial Council to propose a series of measures that promote the use of biosimilar medicines in the National Health System, materialized through the Action Plan to promote the use of medicines market regulators in the SNS. Likewise, it deserves a positive assessment that the Plan is the result of consensus between the Ministry and the CCAAs within the CISNS, regardless of their political persuasion.
