Pharmacokinetics and Pharmacodynamics in Drugs

Pharmacokinetics is currently defined because the study of the time course of drug absorption, distribution, metabolism, and excretion. Clinical pharmacokinetics is that the appliance of pharmacokinetic principles to the safe and effective therapeutic management of drugs during a private patient. Primary goals of clinical pharmacokinetics include enhancing efficacy and decreasing toxicity of a patient’s drug therapy. the event of strong correlations between drug concentrations and their pharmacologic responses has enabled clinicians to use pharmacokinetic principles to actual patient situations. Pharmacodynamics refers to the connection between drug concentration at the situation of action and thus the resulting effect, including the time course and intensity of therapeutic and adverse effects. The effect of a drug present at the situation of action is set by that drug’s binding with a receptor.
