Pharmacokinetics and Pharmacodynamics
Pharmacokinetics is defined as the process of uptake of drugs by the body and the biotransformation, distribution of drugs and their metabolites from the body over a time period. It tells us about how a drug is being affected by the organism intake. Pharmacodynamics on the other side tells us how a drug affects the organism. The effects can include those manifested within humans, animals, microorganisms, or combinations of organisms.
