Key meds Flashcards by Darius Pettiford

Esmolol

Beta-Blockers
“-lol_ drugs
Esmolol, Metoprolol, Labetalol, Atenolol, Propranolol
Antagonists of the beta receptors in the heart and lungs
Causes decreased inotropic(contractility), chronotropic(rate), dromotropic(conduction) effects on heart(good thing): bronchospasm in lungs (bad)

Nicardipine(Cardene)

Calcium Channel Blockers
Diltiazem(cardizem), Nicardipine(Cardene), Verapamil(Calan), Nifedipine(Procardia)

Acts by blocking Ca++ influx into vascular smooth muscle
	Vascular smooth muscle relaxation, especially at coronary arteries
Negative dromotropic effects
	Slowing impulses through SA and AV nodes Vasodilation

Dopamine

Inopressors
Sympathomimetic (adrenergic) agents-
Example: Dopamine, Norepinephrine
Actions-Stimulation of beta-1 receptors
Increased contractility
Increased HR
Indications
Acute LV failure
Low CO states-low perfusion states
Vasogenic shock

Dobutamine

Inodilators
Sympathomimetic(adrenergic) agents
Dobutamine, Milrinone
Actions-stimulation of beta -1 receptors, higher inotropic effects than chronotropic effects
Increase contractility
Dobutamine causes vasodilation
Indications
Acute LV failure
Pulmonary vasoconstriction
High pulmonary vascular constriction
Low Q states-low perfusion states

Phenylephrine

Vasopressors
Sympathomimetic (adrenergic) agents
Neo-synephrine, Vasopressin, Methylene Blue
Actions-stimulation of Alpha -1 & Alpha 2 receptors
Increased vasoconstriction
Very low beta properties
Inhibitors of Nitric oxide-(methylene blue)
Indications
Profound neurogenic shock
Push dose pressors
Vasogenic shock states
Refractory septic shock
