Taken from wikipedia:
'Because of various expression of α₁or β₂receptors, depending on the patient, administration of adrenaline may raise or lower blood pressure, depending whether or not the net increase or decrease in peripheral resistance can balance the positive inotropic and chronotropic effects of adrenaline on the heart, effects which respectively increase the contractility and rate of the heart'
No citation, so it could be pure poop. Can't find anything else about it on the net.
How would that work? How common is it to have low blood pressure as response to adrenaline?
