Adrenaline targets various organs,mainly - the Heart, Blood vessels, Smooth muscles(of bronchi, uterus, gastrointestinal tract,bladder etc.), the eye (radial muscles of iris), skeletal muscles (central nervous system also, but weak effect is seen there), metabolic actions (via liver)
It acts via various alpha and beta receptors present at these target organs.
Its main actions can be simplified as below:
Heart-via beta 1 receptors-Adrenaline increases the Heart rate, force of contraction, cardiac output and conduction velocity
Blood vessels-via alpha and beta2 receptors causes constriction mainly in vessels of skin, kidneys and dilatation in vessels of skeletal muscles, liver.
Bronchial smooth muscles - via beta2 receptors- causes broncho dilatation.
Blood pressure- overall rise in blood pressure
Eye- via alpha1 receptors- contraction of radial muscles if iris,therefore increases size of pupil (mydriasis)
CNS- restlessness, apprehension, tremors
Metabolic action- rise in blood glucose levels, lactic acid level, free fatty acid levels.
