Pharmacology is the branch of biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous molecule which exerts a biochemical or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals. The fie
Two Primary Branches of Pharmacology. The two major branches of pharmacology are: pharmacodynamics and pharmacokinetics. Pharmacodynamics-The study of the relationship between concentrations of drug and the biologic effects (physiological or biochemical) with time.In operational terms âwhat drugs do to the bodyâ.xamples of multiple mechanisms for drug action include: chemical interactions with other molecules due to a drugs acidic or basic properties (e.g. antacids, or Protamine sulfate-a heparin antagonist), their ability to act as a membrane surfactant (amphotericin B), or their ability to denature proteins (astringents).
