2- Nor epinephrine (NE) (Levarterenol, (Nor adrenaline) - It is the chemical mediator librated by postganglionic sympathetic N.ending & act directly on the effector cells. - In therapeutic doses: α R effect and similar β1R effect (on heart) but no β 2 R.
Action of Nor adrenaline (NA) C.V.S : NA increase PR due to intensive vasoconstriction of most vascular bed ( including kidney via α 1R), which lead to increase both S & D Bdp (with increase mean Bdp). This lead to compensatory vagal reflex by stimulation to the baroreceptor reflex , which cause decrease contraction of heart & decrease HR ( called reflex bradycardia).
