Hypertension Flashcards
BP goal for adults over 60 without diabetes or CKD?
Less than 150/90
In patients 18-59 without major comorbidities and in patients over 60 who have diabetes, CKD, or both the BP goal is:
Less than 140/90
In black patients without CKD what medications should be used to treat HTN?
CCB or thiazides
In patients of all races and ages with CKD what is first line pharmacological treatment of hypertension?
ACEI or ARB alone or in combo with another class
Metoprolol, bisoprolol, betaxolol, acebutolol are what?
Beta-1 selective beta blockers that are possibly safer in patients with COPD, asthma, diabetes, and PVD.
What is the only diuretic indicates in the treatment of HTN?
Thiazides
Thiazides MOA:
Inhibit reabsorption of sodium and chloride in the thick ascending loop of henle and the early distal tubules which decreases plasma volume and SV.
Loop diuretics are indicated for?
Patients in heart failure (presence of edema)
What is MOA of an ACEI?
Prevents formation of angiotensin II a potent vasoconstrictor. Also inhibits degradation of bradykinin and increases synthesis of vasodilating prostaglandins. This reduces arterial pressure, preload, and afterload.
What do ACEI end in?
-pril
Can you use an ACEI or an ARB in pregnancy?
No
Biggest side effect of an ACEI?
Chronic dry cough (d/t increased bradykinins)
What do ARBs end in?
-sartan
MOA of an ARB:
Blocks binding of angiotensin II. This decreases ADHD secretion, aldosterone secretion which stops vasoconstriction and increases Na and water elimination.
ARBs should not be used with:
ACEI or renin inhibitor
What classes of HTN medications cause first dose effect?
ARB, Alpha 1 blockers, Alpha 2 blockers
What is the first-dose effect?
Fatigue, dizziness, and syncope. Lay down for 30 minutes after first few doses.
MOA of CCB?
Inhibit movement of calcium ions across the cell membrane causing muscle relaxation and vasodilation in the CV system.
2 types of CCB:
Dihydropyridines: amlodipine, nicardipine
Nondihydropyridines: diltiazem, verapamil
Dihydropyridines are:
Potent vasodilators
Nondihydropyridines are:
Used to treat tachyarrhythmias. They decrease HR and slow cardiac conduction at the AV node.
Vasodilators such as hydralazine and minoxidil should be reserved for patients with:
Essential or severe HTN.
Vasodilators MOA:
Cause smooth muscle relaxation resulting in a reduction of BP.
Alpha 1 peripheral blockers are used in:
Patients with BPH. Not usually prescribed solely for HTN treatment.
