Popis: Pharmaceutical residues can harm the environment. Therefore any Marketing Authorisation Application (MAA) for a medicinal product for human use shall be accompanied by an “indication of any potential risks presented by the medicinal product for the environment” according to Article 8(3)(g) of the Directive 2001/83/EC. Since 2006 a guideline document from the European Medicines Agency (EMA, formerly EMEA) is available for this task, which is now called the “Environmental Risk Assessment” (ERA). Recently the EMA released a draft revision of an updated ERA guideline. The present paper provides a summary of the intended innovation. A number of options have been discontinued, but some of them cannot be easily recognised, even though they are potentially affecting the MAA and its costs in a relevant way. A new specifically tailored experimental testing course for antibiotics and a secondary poisoning assessment is introduced. The selection of required study types is altered and the environmental fate evaluation is adapted to the scientific progress. In the recent situation it is suggested that marketing authorisation applicants may reconsider the conduct of water/sediment studies for substances not requiring these according to the guideline revision. The new tailored testing approach for antibiotics avoids any vertebrate use, because it demands no fish study, therefore it may be applied henceforth. If the new prescriptions are not yet in force at the point in time of the MAA submission, appropriate waivers should be stated in the ERA. No further HPLC-study types and acute earthworm toxicity tests should be performed, since the guideline update draft does not accept them. In preclinical toxicity and pharmacokinetic studies, additional data gathering on metabolites should be considered in order to avoid unnecessary leaflet warnings. The cost for ERA may change significantly, with a tendency to increase for generic pharmaceutical MAA, but with a possible reduction for substances of low environmental concern. Earlier consideration of ERA in the drug development process is recommended.
