what is pharmacodynamics quizlet
of pharmacodynamics and pharmacokinetics. It will identify the main targets for drug action and allow you to develop an understanding of drug absorp-tion, distribution, metabolism and excretion. Put simply: pharmacodynamics is the effect that drugs have on the body; while pharmacokinetics is the study of the way in which drugs move through the body dur-
Pharmacodynamics is the study of the biochemical and physiologic effects of drugs and their mechanisms of action. It considers both drug action, which refers to the initial consequence of a drug-receptor interaction, and drug effect, which refers to the subsequent effects.The drug action of digoxin, for example, is inhibition of membrane Na + /K + -ATPase; the drug effect is augmentation of cardiac contractility.t considers both drug action, which refers to the initial consequence of a drug-receptor interaction, and drug effect, which refers to the subsequent effects.
