Epinephrine Secretion Inhibition

**Semantic type:** Phenomenon or Process

**Definition:** Epinephrine Secretion Inhibition consists of interference with, or restraint of, activities involved in release across the cell membrane into the bloodstream from the adrenal medulla of a sympathomimetic hormone (epinephrine) that stimulates the alpha- and beta- adrenergic systems, causes systemic vasoconstriction and gastrointestinal relaxation, stimulates the heart, and dilates bronchi and cerebral vessels. Alteration of positive or negative feedback mechanisms can affect hormone release.
