to take certain measures for ensuring the safe use of the medicinal product to be included in the risk management system;
to conduct post-authorisation safety studies;
to comply with obligations on the recording or reporting of suspected adverse reactions which are stricter than those referred to in Title IX;
any other conditions or restrictions with regard to the safe and effective use of the medicinal product;
the existence of an adequate pharmacovigilance system;
to conduct post-authorisation efficacy studies where concerns relating to some aspects of the efficacy of the medicinal product are identified and can be resolved only after the medicinal product has been marketed.

The marketing authorisation shall lay down deadlines for the fulfilment of these conditions where necessary.]
