Medications-Hemodynamics Flashcards
LABETALOL-Category of drug and Mechanism
alpha and Beta-blocker Decrease HR and SV because it blocks both this prevents reflex tachycardia
LABETALOL-COMMON SIDE EFFECT/S
hypotension
HYDRALAZINE- Category of drug and Mechanism
arterial vasodilator
HYDRALAZINE- COMMON SIDE EFFECT/S
reflex tachycardia
METOPROLOL Category of drug and Mechanism
Beta-blocker Decrease HR and SV
DIGOXIN-Category of drug and Mechanism
works in myocardial cells to increase contractility (inotrope)
DIGOXIN COMMON SIDE EFFECT/S
toxicity
NITROGLYCERIN-Category of drug and Mechanism
potent Venoodilator
NITROGLYCERIN COMMON SIDE EFFECT/S
may cause headache
reflex tachycardia
hypotension
AMIODARONE Category of drug and Mechanism
treatment of atrial and ventricular dysrhythmias
AMIODARONE COMMON SIDE EFFECT/S
hypotension
liver functions
NOREPINEPHRINE-Category of drug and Mechanism
Predominantly an alpha-agonist, with some beta-agonism as well.
Inoconstrictor
DOBUTAMINE-Category of drug and Mechanism
Inodilator Beta 1 inotropic increases contractility Slight beta 2 – mild vasodilation Little effect on HR Inodilator
EPINEPHRINE-Category of drug and Mechanism
Inoconstrictor
At lower doses the beta-agonist effects may predominate; with ongoing up-titration there are increasing alpha-agonist effects as well.
EPINEPHRINE COMMON SIDE EFFECT/S
angina, ventricular dysrthmias in ishchemic hearts
MILRINONE-Category of drug and Mechanism
Phosphodiesterase inhibitor
Increases contractility
Causes vasodilation
+Inotrope
Inodilator
MILRINONE COMMON SIDE EFFECT/S
atrial and ventricular dysrhthmias
DOPAMINE Category of drug and Mechanism
Inoconstrictor Inotropic (beta 1) Vasoconstrictive (alpha) higher doses >10mcg/min
Vassopressin Category of drug and Mechanism
V1 receptors – vasoconstriction
phenylephrine
Pure alpha-agonist, causes arterial and venous vasoconstriction.
