For this Discussion, you reflect on a case from your past clinical experiences and consider how a patient’s pharmacokinetic and pharmacodynamic processes may alter his or her response to a drug.
By Day 3 of Week 1
Post a description of the patient case from your experiences, observations, and/or clinical practice from the last 5 years. Then, describe factors that might have influenced pharmacokinetic and pharmacodynamic processes of the patient you identified. Finally, explain details of the personalized plan of care that you would develop based on influencing factors and patient history in your case. Be specific and provide examples.
*Include 3 sources*
MUST BE: A primary, secondary source or Scholarly, peer-reviewed journal
When selecting articles for course assignments, you are advised (unless you are referencing seminal information) to focus on work published within the past five years
As a medical professor, it is important to understand the principles of pharmacokinetics and pharmacodynamics and how they apply to patient care. In this case study, we will reflect on a past clinical experience and consider how pharmacokinetic and pharmacodynamic processes may alter a patient’s response to a drug. We will also discuss factors that might have influenced these processes and develop a personalized plan of care based on this information.
Mrs. J is a 67-year-old female with a history of hypertension and type 2 diabetes. She was prescribed metoprolol, a beta-blocker, to treat her hypertension. However, after a week of taking the medication, she reported feeling dizzy and lethargic, and her blood pressure was still elevated.
Several factors may have influenced the pharmacokinetic and pharmacodynamic processes of Mrs. J. Firstly, her age may have resulted in a decrease in hepatic metabolism and renal excretion, which could have resulted in increased drug levels in her body. Secondly, her diabetes may have altered the absorption and distribution of the drug due to possible gastrointestinal motility changes. Thirdly, she may have had genetic variations in her drug metabolizing enzymes, which could have altered her response to the medication.
Personalized Plan of Care:
To develop a personalized plan of care for Mrs. J, we first need to investigate her drug metabolizing enzymes to determine if she has any genetic variations. We may also consider monitoring her drug levels in her blood to determine if she is receiving the appropriate dose of medication. Additionally, we may need to adjust or change the medication based on potential adverse effects or drug interactions. Lastly, we would work with her to incorporate lifestyle modifications, such as exercise and diet changes, to aid in her blood pressure management.
