Change not granted to the marketing authorisation for Basiron AC (benzoyl peroxide 5% and 10% gel) in the EU

On 28 March 2019, the European Medicines Agency completed a review of Basiron AC (benzoyl peroxide) following a disagreement among EU Member States regarding a change in the marketing authorisation of this medicine. In particular, the Agency was requested to make a recommendation on a change in the medicine’s formulation that would allow for greater stability in warmer countries. As the Agency could not conclude whether the change would impact on the effectiveness and safety of the medicinal product, the change in formulation cannot be granted.
