Pharmacology- PK & PD approach

Pharmacodynamics and pharmacokinetics are the two principal areas of pharmacology. Pharmacodynamics is the study of the molecular, biochemical, and physiological effects of drugs on cellular systems and their mechanisms of action. Pharmacokinetics focuses rather on how the body affects the drug, in terms of its absorption, metabolism, distribution and elimination. Today, pharmacologists use a variety of techniques, including genetics, molecular biology and chemistry, to explain and manipulate the pharmacological action of substances for health purposes. BA and BE frequently rely on pharmacokinetic measures such AUC to assess extent of systemic exposure and Cmax and Tmax to assess rate of systemic absorption.

It has a broad scope, from the discovery of new target molecules, to the effects of drug usage in whole populations. Clinical pharmacologists work in a variety of settings in academia, industry and government. In the laboratory setting they study biomarkers, pharmacokinetics, drug metabolism and genetics. Bioanalytical method techniques and validation plays a vital role in the evaluation and interpretation of bioequivalence, pharmacokinetics, and toxicokinetic studies. Clinical and experimental pharmacology deals with Clinical drug developments & therapeutics. Pharmacogenomics is the study of how genetic variation influences responses to drugs. This includes how genetic variants affect drug metabolism, efficacy and toxicity, with the goal of improving and personalizing drug therapy.
