European Medicines Agency recommends discontinuation of Vimpat 15-mg/ml syrup

Vimpat 15-mg/ml syrup no longer available because of quality defect; other Vimpat presentations remain available for patients with epilepsy

The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended that Vimpat 15-mg/ml syrup should no longer be marketed. The CHMP’s recommendation follows the voluntary recall of Vimpat 15-mg/ml syrup on 15 September 2011. The recall was initiated because of a quality defect in some batches leading to uneven distribution of the active substance lacosamide in the syrup. As this defect could not be remediated, e.g. by changing storage conditions, the Committee concluded that the benefit of Vimpat 15-mg/ml syrup does not outweigh the risk that patients might receive either too much or too little of the active substance, and therefore recommended the permanent discontinuation of Vimpat 15-mg/ml syrup.

Patients should not stop taking their current medication or change their dose without speaking to their doctor.

Doctors should contact patients currently on Vimpat 15-mg/ml syrup as soon as possible to switch them to Vimpat film-coated tablets whenever possible. For patients who cannot take tablets, it may be possible to obtain the United States-approved Vimpat 10-mg/ml liquid formulation, which does not have this quality defect, on a named patient basis (an application for a marketing authorisation for this formulation in the European Union was submitted to the Agency in August 2011 and is currently under review by the CHMP). Otherwise, alternative anti-epileptic treatments may have to be considered.

Pharmacists should return any bottles of Vimpat 15-mg/ml syrup to their supplier.

Vimpat is used to treat partial-onset seizures (epileptic fits starting from one specific part of the brain) as an add-on to other anti-epileptic medicines in patients with epilepsy aged 16 years and older.

The review of the benefits and risks of Vimpat 15-mg/ml syrup started in July 2011. Previously, the Agency was informed by the marketing authorisation holder that a flake-like precipitate had been observed in bottles of Vimpat 15-mg/ml syrup. The precipitate consisted of the active substance lacosamide and was not a contaminant. Further analysis carried out by the company showed that the active substance was not evenly distributed in the syrup, which could lead to patients receiving either too much or too little of the active substance. Although no cases of adverse reactions related to the precipitate, the CHMP agreed to the company’s proposal to recall Vimpat 15-mg/ml syrup from the supply chain on 15 September 2011 as a precautionary measure.

Availability of a liquid formulation is essential for some patients. The Agency has therefore worked with the company to continue to make this important alternative formulation available to patients who need it. The application for a marketing authorisation for a 10-mg/ml liquid formulation is currently under review by the CHMP.

The CHMP’s opinion has now been forwarded to the European Commission for the adoption of a decision.

Notes

  • The recall of Vimpat 15-mg/ml syrup was agreed in July 2011 and initiated on 15 September 2011.
