CEN cardiac pharmacology Flashcards
Chronotropes affect
heart rate at SA node
Cardizem is a
Chronotrope
Inotropes affect…
contractility (force of contraction)
2 inotropes are
dopamine and dobutamine
Dromotropes affect
automaticity (electrical impulse) of the AV node
Beta-blockers (-olol)
type 1 affects the heart
type 2 affect heart and lungs
beta-blockers may mask…
signs of shock and hypoglycemia
ACE inhibitors work on RAAS
blocks conversion of angiotensin 1 to angiotensin 2
ACE inhibitor side effects (least to worst)
dry non-productive cough to angioedema
ARBs (sartans)
inhibits angiotensin 2 receptors-vasodilation-lower BP
Calcium channel blockers (dipine)
ventricular rate control for a-fib and HTN
Nitroglycerine
coronary artery vasodilator
four things nitroglycerine does
reduces preload, afterload, BP and oxygen consumption
nitroglycerine contraindications
within 24 hours of phosphodiesterase inhibitor use (viagra, levitra, cialis)
nitroprusside is a
vasodilator
