[Availability in Spain of "one pill killers" and other highly toxic drugs in infants].

Objective: To prepare a list of highly toxic drugs in infants (HTDs) marketed in Spain, comparing those that reach the lethal dose in a child of 10kg with the ingestion of 1 to 3 units.

Method: HTDs are defined as those capable of causing severe or lethal poisoning in children less than 8-year-old. Severe poisoning is considered as that corresponding to Grade 3 in the Poisoning Severity Score classification and to the "major effects" category in publications in the American Association of Poison Control Centers.
