This course introduces the terms, concepts, and processes of pharmacodynamics. The class will focus upon the pathways by which drugs act upon the body. Factors affecting medication potency, efficacy, and response are emphasized, including age, body mass, gender, administration, genetic factors, and psychological factors are reviewed. The challenges of medication therapy in neonatal, pediatric, geriatric, pregnant, and lactating patients are considered. Specific disorders and abnormalities affecting the body are investigated, and actions and uses of drugs on each body system are covered. 

Topics include:

  • Definition of Pharmacodynamics, including the four pathways
    • Receptor complex
    • Site of Action
    • Mechanism of Action
    • Receptor Site
    • Agonists and Antagonists
    • Dose-Response Curve
    • Half-Life
    • Time-Response Curve
    • Potency
    • Efficacy
    • Therapeutic Index
    • Factors Altering Medication  Response
    • Neonatal and Pediatric Patients
    • Geriatric Patients
    • Pregnant and Lactating Patients
  • The Human Body
    • The Skin (Integumentary)
    • Eyes and Ears
    • Gastrointestinal
    • Musculoskeletal
    • Respiratory
    • Cardiovascular



Course Learning Objectives

Upon successful completion of this course, the student should be able to:

  • Define pharmacodynamics and the four basic pathways involved, including binding to receptor sites, changing physical properties, acting chemically through combining with other substances, and altering a normal metabolic pathway
  • Describe the factors affecting medication potency, efficacy, and response.
  • Explain the challenges of medication therapy in neonatal, pediatric, geriatric, pregnant, and lactating patients
  • Understand and correctly utilize medical terminology related to each body system.
  • Describe the structures, functions, pathologies, and pharmaceutical treatment of the body systems: 
    • The Skin (Integumentary)
    • Eyes and Ear
    • Gastrointestinal
    • Musculoskeletal
    • Respiratory
    • Cardiovascular
  • Define and describe the basic rules and elements of medical terminology as it relates to the body structure.
