Cardiovascular Drugs

Cardiovascular drugs play a crucial role in managing various heart conditions, including arrhythmias, hypertension, and heart failure. These medications are classified based on their mechanism of action and therapeutic use.

Cardiovascular Drugs

Cardiovascular Drugs

AntiAngina

Diltiazem/Cardizem
- Dromotropic
- Inotropic
- Chronotropic
Decreases Angina from coronary artery spasm
lowers HR in A-fib or flutter
Calcium Channel Blocker
Beta Blockers
Nonselective not for COPD or asthma
Lower contractibility
Lower HR
Nitroglycerine/Nitrostat
Cardiac and BP monitoring + Call MD if Systolic < 90
Viagra + Nitro = VERY BAD DAY
Decreases workload
Reduces preload
Dilates Blood vessels
For Angina

Pipes (Blood Vessels)

Plasma (Blood Volume)

Diuretics
Mannitol/Osmitrol

ICP

filter needle, keep warm r\t crystals

Osmotic

Lower fluid levels FAST

EMERGENCY DRUG

Spironolactone/Aldactone (ATI)

Collecting tubial

Triamterene/Dyrenium

Weak

Collecting Tubial

Potassium Sparing

Hydrochlorothiazide/Diuril

2 Hours

Na, Cl, H2O excretion @ distal tubial

For HTN and Peripheral Edema

Furosemide/Lasix

Na, H2O excretion at loop

HTN, Edema, renal disease

Can increase renal blood flow 40%

fast action

High Ceiling Diruetic

Pump (Cardiac Contraction)

Antidysrhythmics
IV Calcium Channel Blockers

Diltiazem/Cardizem, Verapamil/Calan

Atrial Fib and Flutter

slows conduction

increase refractory period of AV node

Decrease excitability and contractility of myocardium

III  Prolong Repolarization

Amiodarone/Cordarone  (one)

prolongs action potential

increases refractory period

Emergency treatment of V-fib and V arrhythmias

II  Beta Blockers (lol)

Acebutolol (Sectral), Metoprolol (Lopressor), Propranolol (Inderal) (non-selective)

Blocks Beta-1 (antagonist)

High BP

Angina

Dysrhythmias (especially Ventricular)

Block effect Catecholamines

Slow heart rate

I  Fast sodium channel blockers A,B,C

C. No Prototype

Suppress PVC

B. Lidocain/Xylocain

raises ventricular firing threshold

Prolongs repolarization

Slows conduction

A. Procainamide/Pronestyl & quinidine

Lessens likelihood of ectopic beats

increases time for repolarization

decreases conduction velocity & automaticity

Cardiac Glycocides
Dobutamine/Dobutrex

Emergency Drug

Monitor BP and Heart

+inotropic, CHF

+ Beta 1 agonist

Digoxin/Lanoxin

Antidote Digibind

- dromotropic

- chronotropic

+ Inotropic
