Aims:
Additional risk minimization measures (aRMMs) may be needed to ensure that the benefits continue to outweigh the risks for medicines associated with serious risks. Prior research showed an increasing trend in medicines with aRMMs. We assessed whether the European pharmacovigilance legislation may have impacted the number and type of aRMMs.
Methods:
We included new active substances approved between 1 January 2010 and 31 December 2015. Information extracted from the summary of the Risk Management Plan at the time of licensing included date and type of marketing authorization, presence and type of aRMMs. We tested for differences using Pearson's Χ2 test and segmented Poisson regression.
Results:
We identified 231 medicines approved during the study period, of which 30% had aRMMs at the time of licensing. ARMMs were in place for 38% of medicines before July 2012 and for 28% after (p = 0.16). Segmented Poisson regression did not show changes in trend or level of medicines with aRMMs.
Discussion And Conclusion:
During the study period, no significant differences in the proportion or trend of products with aRMMs at the time of licensing before and after the pharmacovigilance legislation were identified.

01:19Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

Conjugate addition results in a thermodynamically stable product. The reaction retains the stronger C=O bond at the expense of the weaker C=C π bond. The process is slow as the β carbon is less electrophilic than the carbonyl carbon.
Direct addition products are...
