Pharmacological management of the Heart and Vascular Diseases Flashcards
What do Alpha Adrenergic Antagonist Agents do?
It reduces peripheral vascular tone by blocking alpha-1-adrenergic receptors
It dilates arterioles and veins, DECREASING BLOOD PRESSURE
what are indications to use Alpha Adrenergic Antagonist Agents?
hypertension
benign prostatic hyperplasia
What are side effects of Alpha Adrenergic Antagonist Agents?
dizziness
palpitations
ORTHOSTATIC HYPOTENSION
drowsiness
What are implications in PT for pts using Alpha Adrenergic Antagonist Agents?
possible dizziness or orthostatic hypotension when rising from sitting or lying position
closely monitor during exercise
What decreases blood pressure and afterload by suppressing the enzyme that converts angiotensin I to angiotensin II
Angiotension-Converting Enzyme (ACE) Inhibitor Agents
What are indications to use ACE inhibitor agents?
hypertension
CONGESTIVE HEART FAILURE
what are side effects of using ACE Inhibitor Agents?
hypotension
dizziness
dry cough
hyperkalemia
hyponatremia
What are implications for Pt with ACE Inhibitor Agents?
avoid sudden changes in posture due to risk of dizziness and fainting from HYPOTENSION
Pts with heart failure should avoid rapid increases in physical activity.
What is the action of Angiotensin II Receptor Antagonist Agents?
It blocks angiotensin II receptors which limit vasoconstriction and stimulation of vascular tissue
What are indications for Angiotensin II Receptor Antagonist Agents?
hypertension
congestive heart failure
What are side effects of Angiotensin II Receptor Antagonist Agents?
dizziness
back and leg pain
angina pectoris
What are examples of Angiotensin II Receptor Antagonist Agents
Cozaar (losartan)
Atacand (candesartan)
Diovan (valsartan)
What is a class I antiarrhythmic agent?
Sodium channel blocker that controls cardiac excitation and conduction
What is a class II antiarrhythmic agent?
It is a beta blocker which inhibits sympathetic activity by blocking B-adrenergic receptors
What is a class III antiarrhythmic agent?
It prolongs repolarization by inhibiting both potassium and sodium channels
What is a class IV antiarrhythmic agent?
It is a calcium channel blocker which depresses depolarization and slow conduction through the AV node
Which is the MOST EFFECTIVE antiarrhythmic agent?
Class III
What is the indication to use antiarrhythmic agents?
cardiac arrhythmia
What are sides effects of antiarrhythmic agents?
exacerbation of cardiac arrhythmias
dizziness
hypotension
Implications of antiarrhytmic agents in PT
Encourage pts to adhere to prescribed dosing schedule and immed report any adverse reactions
What are examples of sodium channel blockers?
Quinidine (generic
Xylocaine (lidocaine)
What are examples of beta blockers?
Tenormin (atenolol)
What are examples that provide prolonged repolarization
Cordarone (amiodarone)
What are examples of Calcium channel blockers?
Cardizem (diltiazem)
What do anticoagulant agents do?
They inhibit platelet aggregation and thrombus formation
