CEHTRA offers comprehensive ERA services to ensure pharmaceutical products meet environmental standards. Minimize environmental impact and maximize compliance with our expert guidance. Environmental Risk Assessment (ERA) ERA assesses environmental risks posed by pharmaceutical products. It minimizes drug impact, identifies risk measures, and ensures proper disposal. CEHTRA provides expert guidance and independent study monitoring for compliance.

E-mail Company Your message Send Thank you for your submission! EU's Proposal to Strengthen Environmental Risk Assessment (ERA) for Pharmaceutical Products In the EU, an Environmental Risk Assessment (ERA) has been required since 2006 (CPMP/SWP/4447/00, 20061) for any new application for marketing authorization (MA) for a drug, or when there is a potential for a significant increase in environmental concentrations following changes in use of existing MAs (e.g. addition of new indications). Drugs authorized before this date do not currently require an ERA. To achieve the environmental sustainability ambitions of the European Green Deal, the pharmaceutical industry will have to limit the negative impact of its products (and processes) on the environment, biodiversity and human health. Scientific evidence shows that pharmaceutical products are present in the environment as a result of their manufacture, use by patients and inappropriate disposal. The proposal to reform pharmaceutical legislation (Proposal for a DIRECTIVE OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL on the Union code relating to medicinal products for human use, and repealing Directive 2001/83/EC and Directive 2009/35/EC) meets a number of commitments on the strategic approach to pharmaceuticals in the environment. It strengthens the ERAof medicinal products to ensure better evaluation and limit the potential negative impacts of medicinal products on the environment and public health. In summary, the EU wishes to strengthen ERA for the marketing of pharmaceutical products by : Strengthening the ERA , by introducing a ground for refusal of marketing authorization when companies fail to provide sufficient evidence for ERA, or if the proposed risk mitigation measures are not sufficient to address the risks. Establish clearer requirements for ERA, including compliance with scientific guidelines, regular ERA updates and post-authorization obligation for additional ERA studies. Extend the scope of ERA to environmental risks arising from antibiotic manufacturing. Extend ERA to all products already on the market and potentially harmful to the environment. (COMMUNICATION FROM THE COMMISSION TO THE EUROPEAN PARLIAMENT, THE COUNCIL, THE EUROPEAN ECONOMIC AND SOCIAL COMMITTEE AND THE COMMITTEE OF THE REGIONS, Reform of the pharmaceutical legislation and measures addressing antimicrobial resistance, 26.4.2023) The aim of an ERA for pharmaceutical products is to : minimize the amount of drug released into the environment through appropriate measures. identify specific risk minimization measures to be undertaken by users. appropriate labeling, to facilitate proper disposal of the drug by patients/healthcare professionals (e.g. ensuring that drugs are disposed of in special containers or returned to pharmacies). The ERA is divided into 3 phases: Phase I: aims to identify the total environmental exposure of pharmaceutical products based on dosage and prevalence of the targeted pathology, and to study their potential for bioaccumulation and persistence in the environment. If specific risks are identified (estimated concentration in the environment greater than 0.01 µg/L, PBT substance or substance of concern), further assessment and a number of studies must be carried out (Phase IIA). Phase IIA: Phase II tests identify the fate of drugs in the environment and their potential effects on representative aquatic and terrestrial organisms, in order to assess whether the risk is acceptable. Phase IIB: If the risk is not considered acceptable, a refined assessment must be carried out (additional studies, modeling of environmental concentrations, risk management measures to be implemented). At CEHTRA, our ecotoxicologists can help you to prepare your ERA dossiers and monitor the studies required We have completed dozens of ERA dossiers in accordance with current guidelines. We are 100% independent of CROs , so we help our customers to carry out only the essential tests . The monitoring of studies by our consultants also ensures that our study reports are as robust as possible .

EU POISON CENTER NOTIFICATION (PCN) Annex VIII to CLP regulation was released in March 2017 to harmonise the variations between poison centre notifications among members states and the new harmonised system became effective from January 2021 (extended from January 2020). Importers and downstream users placing hazardous mixtures (with a health and/or physical effect classification) on the EU market are to provide specific information on your mixtures to the centralized EU poison centre before placing theses mixture on the market. They will have to: Register a unique formula identifier (UFI), Include the UFI on the label for professional and consumer use, Include the UFI in section 1.1 of the Safety Data Sheet (SDS) for industrial use. Provide and submit to the ECHA harmonised submission portal: The full chemical composition of the mixture Toxicological information of the mixture (SDS Section 11) Product category (according to the new EU product categorization system EUPCS) The safety data sheet and label in the country’s language The UFI (a 16-character alphanumeric code that uniquely identifies a formula (mixture composition) in the EU and can be generated on the UFI generator ECHA created) The obligation lies with EU Legal entity (non-EU supplier of the mixture cannot replace the EU-based duty holder). A duty holder can entrust a third party (e.g. CEHTRA) to complete the PCN on their behalf. Importers and downstream users placing mixtures on the market not already notified under national legislation must comply with Annex VIII of the Regulation from the following dates: Hazardous mixtures for consumer and professional use: January 1, 2021 Hazardous mixtures for industrial use: January 1, 2024. If the mixture is already on the market and already notified to the local poison centre of the Member State, the date of compliance is 1st January 2025.
