Antianginal Agents Flashcards
Used to manage angina pectoris and work by relaxing blood vessels.
Drug Classification
Nitrates
What are the therapeutic actions of nitrates?
Relax and dilate veins, arteries, and capillaries
This action helps in reducing blood pressure and alleviating angina.
How do nitrates work in the body?
Act directly on smooth muscle to cause relaxation and depress muscle tone of blood vessels.
Indications for nitrates include ________.
Prevention & treatment of angina pectoris attacks.
Contraindications for nitrates include ________.
Severe anemia, head trauma/cerebral hemorrhage.
Cautions when using nitrates include ________.
Pregnancy/lactation, hepatic/renal disease, hypotension, hypovolemia, conditions that limit cardiac output.
Drug interactions with nitrates include ________.
Ergot derivatives, heparin, ED drugs: sildenafil, tadalafil, vardenafil.
Common adverse effects of nitrates include ________.
CNS – headache, dizziness, weakness; GI – nausea/vomiting; CV – hypotension; Misc. – flushing, pallor, increased perspiration.
What is the nursing process consideration for nitrates (ADPIE)?
Assessment, Diagnosis, Planning, Implementation, Evaluation.
Drug Classification: ________
Beta-blockers
Beta-blockers are commonly used for hypertension and heart conditions.
What are the therapeutic actions of beta-blockers?
They reduce heart rate and contractility, lowering blood pressure.
Indications for beta-blockers include ________.
Hypertension, angina, heart failure.
Contraindications for beta-blockers include ________.
Severe bradycardia, heart block, asthma.
Cautions when using beta-blockers include ________.
Diabetes, liver impairment.
Common adverse effects of beta-blockers include ________.
Fatigue, dizziness, bradycardia.
Drug Classification: ________
Calcium Channel Blockers
Calcium channel blockers are used to treat hypertension and angina.
What are the therapeutic actions of calcium channel blockers?
They inhibit calcium influx into cardiac and smooth muscle, causing relaxation.
Indications for calcium channel blockers include ________.
Hypertension, angina, certain arrhythmias.
Contraindications for calcium channel blockers include ________.
Severe hypotension, heart block.
Cautions when using calcium channel blockers include ________.
Heart failure, liver impairment.
Common adverse effects of calcium channel blockers include ________.
Dizziness, flushing, peripheral edema.
