Final answer:
The study of drug interaction with mechanisms of the body is known as pharmacokinetics, which covers ADME characteristics and involves studying a drug's bioavailability, metabolism, and excretion. The correct answer is option: b. pharmacokinetics.
Step-by-step explanation:
The study of drug interaction with mechanisms of the body is best described by the term "pharmacokinetics."
Pharmacokinetics is an essential aspect of the drug discovery and development process, examining how a drug is absorbed, distributed, metabolized, and excreted (ADME) by the body. It involves determining the drug's bioavailability, clearance, elimination half-life, and possible interactions with other substances.
Also, pharmacokinetics integrates with pharmacodynamics to understand a drug's pharmacology through assessing different species in pre-clinical trials as well as examining multiple-dose attributes and the metabolic profile in humans during clinical trials.
