Production-related contamination with N-nitrosodiethylamine (NDEA) in the active ingredient valsartan from the manufacturer "Mylan Laboratory Limited".

Safety warnings | Medicines | 23/11/2018

"Valsartan/HCT ratiopharm 80 mg/12.5 mg Film-Coated Tablets" and "Valsartan/HCT ratiopharm 160 mg/25 mg Film-Coated Tablets" (active ingredient: valsartan) have been approved for the treatment of hypertension since August 16, 2013.

In the course of further sartan reviews (a specific class of blood pressure medication), an impurity with N-nitrosodiethylamine (NDEA) was detected in the valsartan active ingredient from the manufacturer "Mylan Laboratory Limited" in Hyderabad, India. NDEA and its related compound N-nitrosodimethylamine (NDMA) are classified as probable human carcinogens by the WHO International Agency for Research on Cancer and the EU.

As a result, the European Directorate for the Quality of Medicines (EDQM) has lifted the existing CEP (= Certificate of Suitability for Quality Control in the Manufacture of an Active Substance) of the active substance manufacturer "Mylan Laboratory Limited" in order to prevent the further use of the active substance valsartan manufactured there in the EU.

Therefore, an EU-wide recall and investigations concerning the extent of contamination of the affected proprietary medicinal products have been initiated.

An initial scientific assessment of the hazard potential is currently taking place at the European level. However, since such contamination cannot be tolerated on the basis of the precautionary principle, a recall of all potentially affected medicinal specialties is being carried out. Further investigations are currently underway throughout Europe and are being coordinated by the European Medicines Agency (EMA) and agreed jointly with the member states. The aim of the procedure is to take harmonized measures throughout Europe to protect patients.

Patients taking valsartan-containing medicinal products should never discontinue the medicinal products without consulting their attending physician, as the health risk of discontinuation is many times higher than the potential risk of contamination. According to current knowledge, there is no acute patient risk.

Measures at EU level

Due to the identification of the impurity and the resulting withdrawal of the CEP by the EDQM and the publication of the EMA(, the marketing authorization holders have withdrawn the affected batches from the market.

Situation in Austria

In Austria, the following proprietary medicinal products are affected:

  • Valsartan/HCT ratiopharm 80 mg/12.5 mg film-coated tablets.
  • Valsartan/HCT ratiopharm 160 mg/25 mg Film-Coated Tablets

Not all batches contain the active ingredient of the manufacturer "Mylan Laboratory Limited", which is why only the affected batches are being recalled for these two medicinal specialties.

The batches with active ingredient of the alternatively used manufacturer "Jubilant Generics Limited" in India are not affected by this contamination and therefore not subject of the current recall.

The marketing authorization holder "Teva B.V." is recalling the following batches from the market at pharmacy level in close coordination with the Federal Office for Safety in Health Care:

BASG has not received any adverse event reports from Austria.

Recommendations of the BASG

Recommendations for Patients: Patients taking valsartan-containing proprietary medicinal products should never discontinue the proprietary medicinal products without consulting their treating physician, as the health risk of discontinuation is many times higher than the potential risk from contamination. According to current knowledge, there is no acute patient risk.
