Cardiopulm Pharm Flashcards
Alpha Adrenergic Antagonists
Dilation of arterioles and veins -> Decrease BP
-sins
(doxazosin, prazosin, terazosin)
ACE Inhibitors
Decrease BP and afterload
-prils
(captopril, enalapril, lisinopril, ramipril)
Angiotensin II Receptor Antagonists
–> Vasodilation (decrease BP)
Losartan, candesartan, valsartan
Antiarrhythmic Agents
4 classes (sodium channel blockers, beta blockers, inhibiting K/Na channels, and calcium channel blockers)
Class III (K/Na channel inhibitors) most effective. Prolong repolarization (amiodarone)
Side effects: Exacerbation of arrhythmias
Anticoagulant Agents
Inhibit platelet aggregation
E.g. someone who has had a mechanical valve replacement
Heparin, coumadin (warfarin), Lovenox (enoxaparin)
Antihyperlipidemia Agents
5 categories
Most common: Statins
Side effects: HA, GI distress, myalgia, rash
Lipitor (atorvastatin), Zocor (simvastatin), Tricor (fenofibrate)
Antiplatelet/ Antithrombotic
Inhibit platelet aggregation (less strong than anticoagulant)
Bayer (aspirin), Plavix (clopidogrel)
Beta blockers
Decrease HR and contractility (block beta-adrenergic receptors)
Diminished HR and BP response to exercise
Atenolol, metoprolol (lopressor)
Calcium Channel Blockers
Decrease entry of Ca into smooth muscle –> vasodilation, decreased cardiac contractility
Side effects: Congestive heart failure/ fluid overload
Amlodipine, nifedipine, verapamil, diltiazem
Diuretics
Increase excretion of sidum and urine –> decrease BP
Thiazide: chlorothiazide
Loop: Lasix
Potassium Sparing: Dyrenium
Nitrates
Smooth muscle relaxation, dilation of peripheral vessels –> decrease ischemia
Nitroglycerin, isordil (isosorbide dinitrate), amyl nitrite solution
Positive inotropic agents
Increase force and velocity of myocardial contraction, slow heart rate, decrease sympathetic activation
Side effects: Arrhythmias
PT Implications: Monitor HR and teach patient to take their pulse. Rate should stay 60-100
Lanoxin (digoxin)
Thrombolytic Agents
Conversion of plasminogen to plasmin –> clot breakdown
Kinlytic (urokinase), Activase (alteplase)
Enhanced Extracorporeal Counterpulsation
Inflation of pressure cuffs on the LEs to assist with venous return to the heart.
Intra-aortic balloon counterpulsation
Inflation and deflation of a balloon surgically placed into the aorta, providing circulatory assistance for patients after infarction or with cardiogenic shock.
