The PPR Panel noted that there is no case documented in the scientific literature where independent action provided more conservative predictions of combination effects than dose addition, and where at the same time independent action also produced accurate predictions. The use of independent action as an assessment concept for combination effects requires demonstration that modes of action of individual substances in a mixture are strictly independent, a condition that can rarely be met in practice.
