[Acute nicardipine and nifedipine poisoning. Multicenter study. Cooperative study by the french poison control centers and the ARIT].

A study, that was realized by the French Association of Poison Control Centers, tried to estimate the toxicity of Dihydropyridine derivatives towards human beings, in comparison with other calcium antagonists, said to be more toxic. Though, the toxicity of the Dihydropyridine derivatives happens to be far less important considering the rarity or absence of their cardiac effects, it must not however be underestimated in the case of a mass ingestion, or if they are taken simultaneously with psychotropic or cardiotropic drugs.
