It is important to make the distinction that a tablet contains a variety of other potentially inert substances apart from ...
In the fields of medicine, biotechnology, and pharmacology, drug discovery is the process by which new candidate medications are discovered. [ 1 ] Historically, drugs were discovered by identifying the active ingredient from traditional remedies or by serendipitous discovery, as with penicillin .
Pharmacokinetics is based on mathematical modeling that places great emphasis on the relationship between drug plasma concentration and the time elapsed since the drug's administration. Pharmacokinetics is the study of how an organism affects the drug, whereas pharmacodynamics (PD) is the study of how the drug affects the organism.
