Other countries or regions applying FDA post-approval change and EMA post-approval variation guidelines have timelines of 6 months or less (Hoath et al, 2016, Murray, 2016). The research aims to identify opportunities for alignment of the post-approval changes categories of Central America (CA) and Dominican Republic (DR) National Regulatory Agencies (NRA) with the riskbased categories of FDA and EMA as encouraged by the ICH. The FDA and EMA are considered reference authorities for many countries, as they are Stringent Authorities.enPost-approval changeDominican RepublicCentral AmericaNational Regulatory AgenciesUniversity of Western Cape
