The debate between me and a hard to prove friend is what is the common usage or are they both right. He says that it is completely wrong grammar to say Happy memorial day weekend. He is near impossible to prove so any reference would be great.
Noun. 1. pharmacokinetics-the study of the action of drugs in the body: method and rate of excretion; duration of effect; etc. materia medica, pharmacological medicine, pharmacology-the science or study of drugs: their preparation and properties and uses and effects. Translations.
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.n indication of the ability of drugs to reach the receptor is obtained from pharmacokinetic parameters that characterize the absorption, distribution, and clearance of a drug. There may not be a simple temporal correlation between plasma concentration of a drug and its therapeutic effect.
