In this episode of the NewlyMeds Podcast, we go back to pharmacology basics with a focused deep dive into two critical medications we’re seeing more and more in EMS: norepinephrine (Levophed) and cefazolin (Ancef).

We break down how norepinephrine works at a physiologic and cellular level, why it’s become a first-line vasopressor in shock, and what matters when titrating pressors in critically ill patients. We also walk through cefazolin from the ground up, including bacterial cell wall physiology, beta-lactam antibiotics, and why early antibiotic administration plays a major role in trauma, sepsis, and septic shock outcomes.
