Recarbrio

Recarbrio can only be obtained with a prescription and it should be used only after consulting a doctor with experience of managing infectious diseases.

Recarbrio is given by infusion (drip) into a vein over 30 minutes. It is given every 6 hours for 5 to 10 days or sometimes up to 14 days, depending on the nature of the infection.

For more information about using Recarbrio, see the package leaflet or contact your doctor or pharmacist.

One of the active substances in Recarbrio, imipenem, kills bacteria and the other two, cilastatin and relebactam, increase imipenem’s effectiveness in different ways.

Imipenem interferes with bacterial proteins that are important for building the bacterial cell wall. This results in defective cell walls that collapse and cause the bacteria to die. Imipenem is quickly broken down by the kidneys and the cilastatin in Recarbrio prevents this breakdown and so allows imipenem to work for longer. The third active substance, relebactam, blocks enzymes in the bacteria called beta-lactamases. These enzymes break down antibiotics such as imipenem and stop them working.

In a main study in 47 adults with infections caused by Gram-negative bacteria, 71% of patients treated with Recarbrio had a favourable outcome (based on their symptoms and test results) compared with 70% of patients treated with another combination (colistin, imipenem and cilastatin).

Patients in this study had serious infections that were resistant to treatment with imipenem plus cilastatin. Patients were treated for pneumonia caught in hospital, complicated intra-abdominal infection (infection that has spread in the belly with swelling and build-up of pus) and complicated urinary tract infection (infection extending beyond the bladder into the kidneys).

The most common side effect with Recarbrio (which may affect up to 1 in 10 people) is diarrhoea.

Recarbrio must not be used in patients who are hypersensitive (allergic) to imipenem and other carbapenem antibiotics (such as ertapenem and meropenem) or in patients who have had a severe allergic reaction to the broader class of beta-lactam antibiotics (such as penicillins and cephalosporins).

For the full list of side effects and restrictions, see the package leaflet.

The number of patients in the main study was too small to show conclusively that Recarbrio is effective against infections caused by Gram-negative bacteria that have become resistant to imipenem. However, studies on how the medicine works in the body provided more evidence of its effectiveness.

Recarbrio can therefore be useful when there is limited choice of treatment for bacterial infections resistant to imipenem and other carbapenem antibiotics. Recarbrio's side effects, which are similar to those of imipenem with cilastatin, are acceptable. The European Medicines Agency therefore decided that Recarbrio’s benefits are greater than its risks and it can be authorised for use in the EU.

Recommendations and precautions to be followed by healthcare professionals and patients for the safe and effective use of Recarbrio have been included in the summary of product characteristics and the package leaflet.

As for all medicines, data on the use of Recarbrio are continuously monitored. Side effects reported with Recarbrio are carefully evaluated and any necessary action taken to protect patients.

Recarbrio received a marketing authorisation valid throughout the EU on 13 February 2020.
