Toxicodynamics, termed pharmacodynamics in pharmacology, describes the dynamic interactions of a toxicant with a biological target and its biological effects. [1] A biological target , also known as the site of action, can be binding proteins, ion channels , DNA , or a variety of other receptors.
It is an application of pharmacokinetics to determine the relationship between the systemic exposure of a compound and its toxicity.It is used primarily for establishing relationships between exposures in toxicology experiments in animals and the corresponding exposures in humans.

Toxicodynamics (TD) and pharmacodynamics (PD) link a therapeutic agent or toxicant, or toxin (xenobiotic)'s dosage to the features, amount, and time course of its biological action. [11] The mechanism of action is a crucial factor in determining effect and toxicity of the drug, taking in consideration the pharmacokinetic (PK) factors. [12]
