Walden University Wk 2 Pharmacokinetics and Pharmacodynamics Discussion
A professional who prescribes medications must have an exhaustive
knowledge of pharmacology. Even though you may not need as deep an
understanding of pharmacology as such a professional, obtaining a
fundamental knowledge enables you to provide relevant and useful
information regarding medications as you interact with patients. In
this Discussion, you apply your learning from this week’s resources as
you analyze the pharmacology of a particular medication.
Select a medication relevant to this course, and consider how and
why you think it is relevant. Research online for the medication
package insert or label (typically a PDF version of the package insert
or label information can be found on the drug company’s website).
Write the name of the medication you
selected, explaining why you think it is relevant to the course. Then,
describe the routes of administration, pharmacokinetics, and
pharmacodynamics of the medication you selected, being sure to explain
how the medication’s routes of administration, dose-response curves,
ED50, and LD50 interact.
Finally, identify two facts about this medication that you might
address with a patient, explaining why you might address them and how.
