The way a medicine is processed in the body is known as pharmacokinetics. So, how is the medicine absorbed, how is it dispersed throughout the body, where is it disseminated, how is it metabolized, and how is it eliminated? It is primarily concerned with the medication and the human body. The intricate interactions between the drug, the human body, and then the pathogen that may be causing an infection in the patient are taken into account by pharmacodynamics. So, how does the antibiotic destroy the pathogen that may be causing the infection, and how can we dose the medicine to maximize that killing activity profile?”
Pharmacokinetics can be defined as "what the body does to the drug." The intensity of a drug's impact in relation to its concentration in a body fluid, usually at the site of action, is referred to as pharmacodynamics. It can be summarized as follows: "what the medicine does to the body."
