Mechanism Of Action
Epinephrine acts on both alpha and beta-adrenergic receptors.
Through its action on alpha-adrenergic receptors, epinephrine lessens the vasodilation and increased vascular permeability that occurs during anaphylaxis, which can lead to loss of intravascular fluid volume and hypotension.
Epinephrine also alleviates pruritus, urticaria, and angioedema and may relieve gastrointestinal and genitourinary symptoms associated with anaphylaxis because of its relaxer effects on the smooth muscle of the stomach, intestine, uterus and urinary bladder.
When given subcutaneously or intramuscularly, epinephrine has a rapid onset and short duration of action.
