Norepinephrine also known as noradrenaline is a excitatory neurotransmitter that is produced by the adrenal medulla or made from dopamine. High levels of norepinephrine are linked to anxiety, stress, high blood pressure, and hyperactivity. Low levels are linked to lack of energy, focus, and motivation. Neurotransmitter Levels

Low-dose dopamine should not be used for renal protective effects. Level 2. Maintain mean arterial pressure (MAP) ≥ 65 mmHg or as needed to achieve adequate end-organ perfusion (e.g. cerebral perfusion pressure, abdominal perfusion pressure, urinary output). Norepinephrine is the first line agent when vasopressors are indicated.

Dopamine can be converted to norepinephrine, which can be converted to epinephrine. Norepinephrine causes the fight-or-flight response, while epinephrine has the opposite effect. Serotonin: Like the catecholamines, synthesized from an amino acid (tryptophan). Depression is linked to abnormally low serotonin activity. Glutamate/GABA:

Norepinephrine is a more potent alpha 1. agonist than dopamine and may be more effective at treating hypotension in patients with septic shock. Dopamine may be particularly useful in patients with compromised systolic function but causes more tachycardia and may be more arrhythmogenic.

Low dose dopamine should NOT be used for renal protection. Norepinephrine has better outcomes than dopamine with no affect on dopamine receptors in the brain. Phenylephrine and Epinephrine should not be used as first line agents in septic shock.

Low levels of norepinephrine are associated with a loss of alertness, poor memory, and depression. Norepinephrine appears to be the neurotransmitter of “arousal” and for that reason, lower-than-normal levels of this neurotransmitter produce below-average levels of arousal and interest, a symptom found in several psychiatric conditions ...

Low levels of Dopamine make concentration and focus very difficult with low levels also associated with Attention-Deficit Hyperactivity Disorder (ADHD). On the other end of the Dopamine dipstick, as Dopamine levels in the brain begin to raise, we become excited/energized, then suspicious and paranoid, then finally hyperstimulated by our ...
