Pharmacokinetics is the study of how an organism affects a drug, whereas pharmacodynamics (PD) is the study of how the drug affects the organism.
<h3><u>What is </u><u>
pharmacodynamics ?</u></h3>
The study of a drug's biochemical and physiological effects is known as pharmacodynamics (PD) (especially pharmaceutical drugs). Animals (including humans), microbes, or mixtures of species may exhibit the effects (for example, infection).
The two primary subfields of pharmacology, which is a discipline of biology concerned with the study of how chemical compounds, both endogenous and exogenous, interact with living things, are pharmacodynamics and pharmacokinetics.
Pharmacodynamics, in particular, is the study of how a medication affects an organism; pharmacokinetics, on the other hand, is the study of how the drug impacts the organism. Together, they have an impact on dosage, benefits, and negative effects. When used together, such as when discussing PK/PD models, pharmacodynamics and pharmacokinetics are commonly referred to as PD and PK, respectively.
