what are pharmacodynamic properties of a drug
Abstract. Drugs may interact with other drugs or any diet or dietary supplement taken at the same time. Interactions may be pharmacodynamic in which interaction is close to the target organ and involves direct antagonism or addition of pharmacological properties.rug interactions are usually described as pharmacodynamic (where changes in drug action occur in the area of the target tissue) or pharmacokinetic (when one drug affects the absorption, distribution or excretion of another).
