Mechanism of Action
Natural catecholamine with both a- and b-adrenergic agonist activity.
Can produce the following cardiovascular responses
Increased systemic vascular response
Increased systolic and diastolic BPs
Increased electrical activity in the myocardium
Increased coronary and cerebral blood flow
Increased strength of myocardial contraction
Increased myocardial oxygen requirements
Increased automaticity
Indications
Improved coronary and cerebral profusion is the primary beneficial effect of
epinephrine during cardiac arrest. May also increase automaticity and make
VF more susceptible to DC countershock.
Infusions can be used to treat profound symptomatic bradycardia.
Used IVP in the treatment of severe anaphylaxis.
