PHARM - Cardiac, Respiratory, Endocrine Flashcards
Types of heart drugs (6)
- Beta blockers
- ACE inhibitors/ARB inhibitors
- Nitrates/vasodilators
- Calcium channel blockers
- Anti-arrhythmics
- Anti-coagulants/anti-platelets
Common heart conditions (12)
- cardiomyopathy
- cholesterol
- AAA
- Atrial fibrillation
- Arrhythmias
- cardiac arrest
- STEMI
- angina
- HTN
- endocarditis
- pericarditis
- non-ischemic chest pain - can be related to any of the above conditions (primarily endocarditis and pericarditis; and breathing disorders like pneumonia)
Anti-arrhythmic drugs
- Class 2 Beta blockers that block impulses that cause irregular heart beats
- interferes with hormonal influences such as adrenaline on the heart cells
- helps reduce BP and rate
- Suppresses abnormal rhythms of the heart (beating too quickly or slowly)
Conditions warranting use of anti-arrhythmics
- Atrial fibrillation
- Atrial flutter
- SVT
- Irregulary bradycardia
- uncontrolled tachycardia
Drug names: anti-arrhythmics
- amiodarone
- procainamide
- metoprolol - does not fall into anti-arrhythmics family but is a BETA BLOCKER with anti-arrhythmic qualities
- Verapamil
Adverse reactions and side effects of anti-arrhythmics
- arrhythmia worsens
- slower heart rates can sometimes be dangerous (may put your heart into asystole before SA node starts firing again to put heart back into NSR)
- chest pains
- diplopia
- edema to lower extremities - backflow and improper circulation
Beta-blockers
- known to block Beta -1 adrenergic ?blocking agents (did she mean receptors)
- help reduce BP
- work by blocking effects of hormone epinephrine and norepinephrine
- heart beats more slowly and with less force thereby reducing BP
- some affect HR while others affect HR and blood vessels (depends on your comorbidities and hx)
- Use of BB can also result in bronchoconstriction in patients with asthma
- this is because although it works on beta-1 receptors it may also work on some other beta cell (such as beta-2 leading to bronchoconstriction and potentially asthma attacks)
- varied in effects (mild to significant BBs)
Family name for Beta-blockers
-lol or -olol
Effect of beta-blockers (i.e. chronotropic, ionotropic, etc.)
-ve chronotropic, -ve ionotropic
Beta-blockers usually keep HR in what range
50-60 BPM range; never over 80-100 BPM
Describe the physiological changes that occur with use of beta blockers.
- beta blockers bind to beta-1 receptors which do not allow norepinephrine and epineprhine to bind to receptors (affects receptors in the heart and blood vessels)
- arteries are dilated which lowers blood pressure
- beta blockers also slow SA node whcih allows the left ventricle to fill completely, lowering heart workload

Conditions for Beta blockers
- chest pain (from a variety of cardiac conditions)
- HTN
- Post STEMI
- Cardiomyopathy
- Arrhythmias such as a-fib
The LOLs
- Acebutolol
- Atenolol
- Bisoprolol
- Metoprolol
- Propanolol
- Nadolol
Adverse Reactions and Side Effects of Beta-blockers
- dizziness, weakness
- drowsiness or fatigue
- cold hands or feet - can result in gangrene, with increased risk in those with some sort of peripheral vascular disease)
- dry mouth, skin and eyes
- headache
- upset stomach
- diarrhea or constipation (depending on diet)
You come on scene to a patient whom is feeling faint. His medications include: atenolol, bisoprolol, and lasix. He most likely has a hx of?
a) MI
b) HTN
c) CA (cancer)
d) enlarged prostate
can be a) or b)
+ this patient is on lasix which is a diuretic for reducing high BP or getting water out of the heart after surgeries/heart attack
ACE Inhibitors
- aka Angiotensin Converting Enzyme Inhibitors
- stop the body’s ability to convert angiotensin I to angiotensin II (working at the lungs)
- works by binding with smooth musles of arteries, allowing arteries to relax and dilate, increasing the amount of blood your heart pumps - raises blood flow and return
- helps to lower heart’s work load and lowers blood pressure
- also treats heart failure - because it works on our kidneys
Angiotensin Converting Enzyme (ACE)
- central component of the renin angiotensin system which controls BP by regulating volume of fluids in the body
- Angiotensinogen released from liver, renin that is released from kidney acts on angiotensinogen to convert it to angiotensin I
- converts Angiotensin I to active vasoconstrictor angiotensin 2 at the lungs
- primarily works on the kidneys to increase sodium and water retention, and everyone has ACE!

Common adverse effect of ACE inhibitors
This adverse effect would cause which population to not be a candidate for ACE inhibitors?
dry tickly cough
this is an adverse effect rather than a side effect because if the coughing can’t be stopped then this can lead to COPD exacerbations which are equivalent to significant asthma attacks - therefore those with COPD or emphysema would not be a candidate for ACE inhibitors
Family name for ACE inhibitors
-pril
Conditions for ACE inhibitors
- heart failure
- HTN
- prevention of kidney damage from DM
- prevention of continuous damage after MI
The PRIL’s
- Captopril
- Enalapril
- Fosinopril
- Lisinopril
- Quinapril
- Ramipril
- these can be marketed (aka have brand names)
Adverse Reactions and Side Effects of Prils
- dry cough
- hyperkalemia
- fatigue
- dizziness
- headaches
- loss of taste
Angiotensin Receptor Blocker (ARB)
- Angiotensin 2 receptor blocker helps lower BP
- works the same as ACE inhibitors but without the “dry tickly cough”
- blood vessels dilate and BP is reduced
Family name for Angiotensin Receptor Blocker (ARB)
Sartan
