Q

Adrenaline Mechanism

A
  1. Stimulates alpha (heart) and beta (lungs) receptors.

Alpha receptor binding causes smooth muscle contraction, Vasoconstriction. Furthermore, increases in inotropy (cardiac contraction), increase in heart rate and increase in condition of electrical impulses to the heart.

Beta simulation cause smooth muscle relaxation, skeletal muscle vasodilation, bronchodilation and stabilising mast cell membrane reducing histamine response.
