Tromethamine, commonly known as THAM, is a parenteral systemic alkalizing agent historically used for the prevention and correction of severe metabolic acidosis in critical care settings. It has specific applications, particularly during cardiac bypass surgery and cardiac arrest, where it helps sustain vital functions by neutralizing excess acid.

Norepinephrine, marketed under brand names like Norad and Levophed, is a critical sympathomimetic drug used in medical emergencies to increase and maintain blood pressure. We give Norad injections primarily to combat life-threatening hypotension caused by conditions such as septic shock and cardiac arrest, when fluid resuscitation alone is not enough.

Norepinephrine, also known as noradrenaline, acts as both a neurotransmitter and a hormone, playing a vital role in regulating the body's fight-or-flight response. Understanding what is the main purpose of norepinephrine is key to comprehending its widespread effects on alertness, attention, stress, and blood pressure.
