Pharmacodynamics
Also known as: pd
What the drug does to the body: the relationship between concentration and effect.
In plain terms
Pharmacokinetics is the dose reaching the receptor; pharmacodynamics is what happens once it arrives. The two together explain why doubling a dose rarely doubles an effect — receptors saturate.
