This course dives into the practical use of atropine, glycopyrrolate, and scopolamine in the perioperative setting, with a focus on how their pharmacokinetics and pharmacodynamics translate into real-world decision making. You’ll review how to choose the right anticholinergic for secretion control, bradycardia prevention, PONV management, and neuromuscular blockade reversal—while minimizing CNS effects and hemodynamic instability. By the end, you’ll be able to confidently match each agent to its ideal clinical role, compare onset and duration profiles, and refine your anesthetic plans to optimize safety and outcomes for your patients.
