Inotropes and vasopressors are essential pharmacological agents used to treat shock, a condition characterized by reduced perfusion to vital organs, leading to multiorgan dysfunction and potentially death. Vasopressors function by inducing vasoconstriction, thereby increasing systemic vascular resistance (SVR), mean arterial pressure (MAP), and organ blood flow. Inotropes enhance cardiac contractility and improve cardiac output (CO), which supports the maintenance of MAP and perfusion. These agents are vital for restoring hemodynamic stability in critically ill patients. This activity reviews the mechanisms of action, pharmacology, and clinical indications for inotropes and vasopressors. Adverse event profiles, appropriate patient populations, and monitoring strategies are described to optimize therapeutic outcomes. The interprofessional team’s role in selecting, administering, and monitoring these agents is emphasized to ensure effective management of conditions requiring vasopressors and inotropes. Objectives: Evaluate the mechanisms of action of various inotropes and vasopressors. Identify the indications for initiating inotropic and vasopressor therapy. Identify the contraindications for vasopressor and inotropic therapy. Implement effective collaboration and communication among interprofessional team members to improve outcomes and treatment efficacy for patients who might benefit from inotropes and vasopressor therapy.

Patients currently taking an MAOI will have a decreased metabolism of adrenergic vasopressors and will require lower doses to avoid toxicity.[6] Most of the medications mentioned above are naturally occurring compounds. There are no common toxicological issues directly related to the medications, metabolites, or preparations of the medications described above.[15][16]

Inotropes and vasopressors are commonly used in the intensive care unit. Since their indications and adverse effects can be critical, an interprofessional team should be involved in ordering, dosing, administering, and monitoring. While clinicians order these medications, patient monitoring is performed by nurses trained in critical care. Pharmacists should verify dosing and check for interactions and contraindications to their use. In addition to vital signs, patient body weight, fluid status, renal function, and peripheral perfusion require continuous monitoring. Regular patient assessment is needed to ensure that the inotropes and vasopressors are tapered if not needed.[17][18] These examples of interprofessional coordination can improve outcomes when patients receive vasopressors and inotropic medications with fewer adverse events.
