EMA requests clearer safety guidance for Pradaxa

The European Medicines Agency (EMA) has requested a label update to provide clearer guidance on the safe use of the anticoagulant Pradaxa (dabigatran).

The review has confirmed the drug’s positive benefit-risk balance as a stroke prevention treatment for certain patients, but stated the need for clearer notes on the medicine’s risks and what to do in case of bleeding.

The Boehringer Ingelheim drug is recommended for patients with non-valvular atrial fibrillation or following hip or knee replacement.

Because all blood-thinning drugs can cause bleeding, the EMA has maintained close post-market surveillance of this product.

The EMA’s scientific advisory committee, the CHMP, found that the incidence of fatal bleedings with Pradaxa in post-marketing data was significantly lower than in the clinical trials that led to the drug’s authorisation in 2008.

In November 2011, a safety review concluded that the drug should be used with caution, and at lower doses, with patients who were elderly or had moderate renal impairment.

Pradaxa “remains an important alternative to other blood-thinning agents,” the EMA said.

However, the guidance for doctors and patients should be strengthened to include details of the risks, when the drug must not be used, and how to manage patients if bleeding occurs.

In particular, patients taking Pradaxa should seek urgent medical attention of they fall or suffer any injury.

The European Commission is expected to confirm this opinion.
