PKPD: The Foundation of Dosing Regimens for Drugs

PKPD or pharmacokinetics is the relationship between a dose of drug that's administered and the concentrations that are observed in the body. In the context of antimicrobials, PKPD is different to other drugs whereby the main action of an antibiotic is on a pathogen,. beta, bacteria, a fungus, or a virus, or whatever it may be. And so there's some slight differences in the definitions which people may apply to PKPD in that context.
