Insights

Pharmacist-to-dose (PTD) protocols did not significantly change target anti-Xa levels in pediatric enoxaparin patients. However, PTD improved the accuracy and speed of achieving therapeutic anticoagulation, demonstrating pharmacists' equal quality of care.

Area of Science:

  • Pediatric pharmacology
  • Pharmacokinetics
  • Anticoagulation therapy

Background:

  • Enoxaparin pharmacokinetics vary in pediatric patients, necessitating anti-Xa level monitoring for effective anticoagulation.
  • Pharmacist-to-dose (PTD) protocols are crucial for optimizing enoxaparin therapy in children for venous thromboembolism prophylaxis and treatment.

Purpose of the Study:

  • To evaluate the impact of implementing a pharmacist-led enoxaparin dosing protocol (PTD) on achieving target anti-Xa concentrations in pediatric patients.
  • To compare the rates of therapeutic anti-Xa concentrations before and after PTD protocol implementation.

Main Methods:

  • Retrospective review of inpatient pediatric enoxaparin use (January 2016-September 2023) at a children's hospital.
  • Assessment of enoxaparin indication, dosing, administration, and anti-Xa concentration timing and goal achievement.
  • Analysis of secondary outcomes including number of anti-Xa levels drawn, dose adjustments, accuracy, and time to goal.

Main Results:

  • No significant difference was observed in the rate of achieving goal anti-Xa concentrations before and after PTD protocol implementation.
  • A higher frequency of appropriately drawn anti-Xa concentrations and a shorter time to goal were noted post-PTD, though not statistically significant.

Conclusions:

  • Implementation of a PTD protocol did not alter the primary outcome of achieving target anti-Xa concentrations.
  • The consistent use of dose adjustment guidelines contributed to similar therapeutic outcomes.
  • Pharmacist involvement, even without altering goal achievement rates, positively impacts the efficiency of monitoring and achieving therapeutic anticoagulation.

Factors Affecting Drug Response: Overview

When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

Nonlinear Pharmacokinetics: Dependence of Elimination Half-Life and Dose Clearance

The elimination half-life and drug clearance of drugs following nonlinear kinetics can vary with dosage. The Michaelis-Menten parameters and drug concentration influence these factors. As the dose increases, the elimination half-life tends to lengthen, resulting in a reduction in clearance and a disproportionately larger area under the curve. The total clearance can be derived from the Michaelis-Menten equation for drugs following a one-compartment model.

Nonlinear Pharmacokinetics: Overview01:19

Nonlinear Pharmacokinetics: Overview

Nonlinear or dose-dependent pharmacokinetics is a phenomenon that occurs when the pharmacokinetic parameters of certain drugs deviate from linear pharmacokinetics at higher doses. These drugs do not follow the expected first-order kinetics, where the rate of drug elimination is directly proportional to the drug concentration. Instead, they exhibit a nonlinear relationship, which can be attributed to several factors.
Nonlinearity can arise due to the saturation of plasma protein-binding or...

Renal Failure: Dose Adjustments01:11

Renal Failure: Dose Adjustments

In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
