Drug Interactions Part 3 (Pharmacodynamic Interactions). Pharmacodynamics describes the actions of a drug on the body and the influence of drug concentrations on the magnitude of the response. 16. The majority of drugs either (a) mimic or inhibit normal physiological/biochemical processes or inhibit pathological processes in animals or (b) inhibit vital processes of endo- or ectoparasites and microbial organisms. This is the concentration of drug when 50% of receptors are occupied: A low K D value indicates that a lower concentration of drug is required to occupy 50% of the receptor, indicating that the drug has a high affinity for the receptor. - Title: Pharmacokinetics and pharmacodynamics Author: Claire Simms Last modified by: Claire Simms Created Date: 1/10/2015 3:09:05 AM Document presentation format, The Nursing Process and Drug Therapy Karen Ruffin RN, MSN.
