[Drug interactions in intensive care medicine]
Summary
Managing polypharmacy in elderly patients is crucial to prevent adverse drug events and drug-drug interactions. Understanding both pharmacokinetic and pharmacodynamic interactions is key for safe medication management.
Area of Science:
- Pharmacology
- Geriatrics
- Clinical Pharmacy
Context:
- Elderly patients with multiple comorbidities often receive polypharmacy.
- An increased number of prescribed drugs correlates with higher risks of adverse effects and drug-drug interactions.
- Collaboration among medical and pharmaceutical professionals is increasingly vital for critically ill patients' drug therapy.
Purpose:
- To highlight the significance of drug-drug interactions in elderly patients undergoing polypharmacy.
- To emphasize the need for a comprehensive understanding of medication management as a collaborative task.
- To underscore the importance of considering both pharmacokinetic and pharmacodynamic interactions to optimize patient therapy and mitigate negative outcomes.
Summary:
- Drug-drug interactions (DDIs) are a significant concern in elderly patients with multiple health conditions who are prescribed numerous medications (polypharmacy).
- Higher drug quantities increase the likelihood of adverse effects and DDIs.
- Drug interactions can be pharmacokinetic, involving enzymes like cytochrome P450 and transport proteins, or pharmacodynamic, such as additive drug effects.
Impact:
- Improved patient outcomes through safer medication management.
- Reduced incidence of adverse drug events and drug-drug interactions in vulnerable patient populations.
- Enhanced interprofessional collaboration for more effective and safe drug therapy, particularly for critically ill patients.

01:25Pharmacokinetics: Drug–Drug Interactions
812
Drug interactions occur when the pharmacological effect of one drug is altered by another substance, either enhancing or diminishing its activity. The drug whose activity is altered is known as the object drug, and the substance causing the alteration is called the agent drug or the precipitant. The net effects of these interactions are mostly undesirable, leading to decreased effectiveness or increased adverse effects. In rare cases, interactions can be beneficial, such as the enhanced...

01:30Drug toxicity: Drug–Drug Interaction
422
Drug–drug interactions can precipitate toxicity through multiple mechanisms. Absorption interactions alter how drugs enter the body, exemplified when ranitidine increases the absorption of basic drugs, while cholestyramine decreases the levels of propranolol. Protein binding interactions occur when drugs share the same binding sites on plasma proteins. Drugs like aspirin and warfarin, when bound in excess, can lead to increased free drug concentrations, enhancing the potential for...

01:26Pharmacokinetics: Drug–Food and Drug–Viral Interactions
683
A drug interaction occurs when the concurrent use of another drug, food, or an external substance alters the pharmacological activity of a drug. This interaction can modify the action of the original drug, affecting its effectiveness and safety.Drug–food interactions are significant as they impact drug absorption, metabolism, and excretion. For example, grapefruit juice is a well-known disruptor of drug metabolism. It inhibits the cytochrome P450 3A4 enzyme, crucial for the metabolism of...

01:24Drug Accumulation During Multiple Dosing: Intermittent IV Infusions
421
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...
