Readability (QRD) Testing of Patinet Information Leaflet (PIL)
Since 2005, marketing authorization holders of medicines are required to have the patient information leafets for their products readability tested. The European Directive 2004/27/EC (a revision of Directive 2001/83/EC) defines it as follows: 'The package leaflet shall reflect the results of consultations with target patient groups to ensure that it is legible, clear and easy to use' .
