English

Subject field(s)
  • Toxicology
  • Pharmacy
  • Environmental Studies and Analyses
DEF

The quality of exerting deleterious effects on an organism or tissue.

CONT

Toxic means able to cause harmful health effects. Toxicity is the ability of a substance to cause harmful health effects. Descriptions of toxicity (e.g. low, moderate, severe, etc.) depend on the amount needed to cause an effect or the severity of the effect.

CONT

In order to achieve therapeutic effects, however, some drugs must be given in amounts that approach the toxic range or that may even reach it for some patients. Accordingly, appropriate observations are needed to detect the approach or onset of toxicity, to reverse it, and to avoid its progression to intolerable proportions.
