his chapter examines the relationships between the cardiovascular, nervous, and renal systems. It then describes diagnostic criteria for hypertension patients, drugs used to treat hypertension and possible adverse reactions, monitoring patient response, and patient education.

This chapter begins by exploring factors that contribute to chronic stable angina, types of drugs used in treatment, and diagnostic criteria for initiating drug therapy. It also examines methods for monitoring patient response to treatment and educating patients on self-care.

This chapter examines the process of prescribing drugs to treat heart failure and explores effects of prescribed drugs, proper dosages, and possible adverse reactions.

This chapter covers drug therapy options for three disorders requiring anticoagulants: venous thromboembolism, atrial fibrillation, and ischemic stroke. It also explains the process of initiating and managing drug therapy for patients with these disorders.

================================================================================================================
Consider the following case studies:
Case Study 1:
Patient AO has a history of obesity and has recently gained 9 pounds. The patient has been diagnosed with hypertension and hyperlipidemia. Drugs currently prescribed include the following:
Atenolol 12.5 mg daily
Doxazosin 8 mg daily
Hydralazine 10 mg qid
Sertraline 25 mg daily
Simvastatin 80 mg daily
Case Study 2:
Patient HM has a history of atrial fibrillation and a transient ischemic attack (TIA). The patient has been diagnosed with type 2 diabetes, hypertension, hyperlipidemia and ischemic heart disease. Drugs currently prescribed include the following:
Warfarin 5 mg daily MWF and 2.5 mg daily T, TH, Sat, Sun
Aspirin 81 mg daily
Metformin 1000 mg po bid
Glyburide 10 mg bid
Atenolol 100 mg po daily
Motrin 200 mg 1–3 tablets every 6 hours as needed for pain
Case Study 3:
Patient CB has a history of strokes. The patient has been diagnosed with type 2 diabetes, hypertension, and hyperlipidemia. Drugs currently prescribed include the following:
Glipizide 10 mg po daily
HCTZ 25 mg daily
Atenolol 25 mg po daily
Hydralazine 25 mg qid
Simvastatin 80 mg daily
Verapamil 180 mg CD daily
================================================================================================================
To prepare:
1))Review Chapters 19 and 20 of the Arcangelo and Peterson text.
2))Select one of the three case studies, as well as one the following factors: genetics, gender, ethnicity, age, or behavior factors.
3))Reflect on how the factor you selected might influence the patient’s pharmacokinetic and pharmacodynamic processes.
4))Consider how changes in the pharmacokinetic and pharmacodynamic processes might impact the patient’s recommended drug therapy.
5))Think about how you might improve the patient’s drug therapy plan based on the pharmacokinetic and pharmacodynamic changes. Reflect on whether you would modify the current drug treatment or provide an alternative treatment option for the patient.
================================================================================================================
Post an explanation of how the factor you selected might influence the pharmacokinetic and pharmacodynamic processes in the patient from the case study you selected. Then, describe how changes in the processes might impact the patient’s recommended drug therapy. Finally, explain how you might improve the patient’s drug therapy plan.
