Antimicrobial resistance

The emerging and steady increase of microbes that are resistant to antimicrobial treatments has become a global public health concern that threatens the effective treatment of infectious diseases. Combatting this threat, particularly resistance to antibiotics, is a high priority for the European Medicines Agency (EMA) and the European medicines regulatory network.

Antimicrobial resistance is when a microbe evolves to become more or fully resistant to antimicrobials which previously could treat it. Antimicrobials include antibiotics, which kill or inhibit the growth of bacteria.

A well-known example of a bacterium that is resistant to a number of antibiotics is meticillin-resistant Staphylococcus aureus (MRSA), which has caused infections that are difficult to treat across the European Union (EU).

The emerging and steady increase in the occurrence of bacteria that are resistant to multiple antibiotics has become a global public health threat due to the lack of therapeutic options to treat certain infections in humans.

Infections by multidrug-resistant bacteria are estimated to cause 33,000 deaths in the EU every year. Amtimicrobial resistance also places a tremendous burden on healthcare systems and society, with an annual cost due to healthcare expenditures and productivity losses estimated at approximately €1.5 billion in the EU.

Although the development of resistance occurs naturally when microorganisms replicate themselves erroneously or when resistant traits are exchanged between them, the use and misuse of antimicrobials accelerates the emergence of resistant strains.

The lack of new antibiotics entering the market exacerbates the problem.

Antimicrobial resistance affects both humans and animals and resistance can also spread from animals to humans through the food chain or direct contact.

EMA role

EMA plays a vital role in the global response to the threat of antimicrobial resistance, by:

  • supporting the development of new medicines and treatment approaches;
  • promoting responsible use of existing antibiotics;
  • collecting antimicrobial consumption data to guide policy and research.

EMA supports a 'One Health' approach, promoting a close and integrated cooperation between the human and veterinary fields. For more information on the Agency's work in each sector, see:

European Commission action plan

Factsheet - One health action plan from European CommissionEMA supports the European Commission's 'One Health' action plan against antimicrobial resistance published on 29 June 2017. For more information, see:

The European Commission also published EU guidelines on the prudent use of antimicrobials in human medicine. This follows the guidelines on prudent use of antimicrobials in veterinary medicines published in 2015.

EMA also supported the European Commission's previous action plan against the rising threats from antimicrobial resistance, by providing scientific input and recommendations on the use of antibiotics in animals, in partnership with other relevant EU bodies, including the European Centre for Disease Prevention and Control (ECDC) and the European Food Safety Authority (EFSA).

Public awareness

To mark European Antibiotic Awareness Day in 2021, EMA updated its set of info-cards with recommendations on what patients, healthcare professionals, veterinarians, public health leaders and the pharmaceutical industry can do daily to make sure these important medicines remain available as effective treatments for EU patients.

EMA encourages users to follow these recommendations and to share them with others.

In June 2016, the European Commission published the results of a Eurobarometer survey on the use and perceptions of antibiotics in the EU. These showed a 6% decrease in antibiotic consumption in the EU in the preceeding seven years, but highlighted a persistent lack of knowledge on the effect of antibiotics among Europeans.

To raise public awareness on antimicrobial resistance, the Dutch Ministry of Health, Welfare and Sport has published short animated online videos on its website.

Working with international partners

EMA, the Japanese Pharmaceuticals and Medical Devices Agency (PMDA) and the United States' Food and Drug Administration (FDA) are working together to facilitate a single development program for new antibacterials that satisfies the regulatory requirements of each of the three agencies.

At a third meeting between the three agencies in October 2017, they agreed to align how clinical trials should be designed to study the effects of new antibiotics in certain indications, such as uncomplicated gonorrhoea or uncomplicated urinary tract infections.

They also committed to working together to explore how to better streamline paediatric development of new antibacterial agents. For more information, see:

At their second meeting in April 2017, the agencies agreed to align their data requirements for certain aspects of the clinical development of new antibiotics in order to stimulate the development of new treatments. For more information, see:

The agencies first met in September 2016 to discuss regulatory approaches for the evaluation of antibacterial agents.

They concluded that a comprehensive and multifaceted response is needed to encourage and accelerate development of new antibacterial medicines, and agreed to explore common regulatory approaches. For more information, see:

Translatlantic cooperation

The EU and the United States (US) established the Transatlantic Task Force on Antimicrobial Resistance (TATFAR) as a result of the 2009 US-EU summit to intensify cooperation in the fight against antimicrobial resistance. By 2021, government agencies from Canada, Norway, and the United Kingdom also joined. EMA is a member of TATFAR.

The taskforce aims to increase levels of communication, coordination and cooperation between the EU and the US on human and veterinary antimicrobials.
