[Pharmacokinetic considerations in critically ill patients]

Area of Science:

• Pharmacology
• Critical Care Medicine
• Clinical Pharmacy

Context:

• Intensive Care Units (ICUs) manage critically ill patients with complex conditions.
• These patients often have comorbidities, organ failure, and drug-drug interactions.
• Standard pharmacokinetic data may not apply, complicating drug therapy.

Purpose:

• To review essential pharmacokinetic considerations for acute ICU patients.
• To highlight how altered pharmacokinetics impact drug efficacy and safety.
• To guide appropriate drug selection and dosage adjustments in critical care.

Summary:

• Critically ill patients exhibit altered pharmacokinetics, differing from healthy individuals.
• Factors like organ failure and comorbidities significantly change drug absorption, distribution, metabolism, and excretion.
• This necessitates a review of pharmacokinetic principles for effective and safe drug management in ICUs.

Impact:

• Optimizing drug therapy in ICUs improves patient outcomes.
• Reduces the risk of sub-therapeutic dosing and drug toxicity.
• Provides a foundation for evidence-based medication management in critical care settings.
