Determination of Multiple Dosing Parameters: Steady-State, Minimum and Maximum Concentrations

Determination of Multiple Dosing Parameters: Steady-State, Minimum and Maximum Concentrations

Gentamicin, an aminoglycoside antibiotic, is commonly administered via intermittent intravenous infusion to treat severe infections. An intermittent one-hour infusion of gentamicin, administered at eight-hour intervals, allows for precise control of plasma drug concentrations, minimizing toxicity while ensuring therapeutic efficacy. Pharmacokinetic principles govern the dynamics of plasma concentrations and can be mathematically described using specific equations.The plasma drug concentration...

Pharmacokinetics in Pediatric Patients: Drug Excretion

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Estimation of k and VD of Aminoglycosides

Estimation of k and V_D of Aminoglycosides

Aminoglycosides are a class of antibiotics used to treat various bacterial infections. Clinicians must determine the elimination rate constant (k) and volume of distribution (VD) to optimize therapeutic efficacy and minimize toxicity. The k value represents the rate at which the drug is removed from the body, and the VD reflects the degree to which the drug distributes into body tissues. Accurately estimating these parameters allows healthcare professionals to tailor drug dosing to individual...

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

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...

Drug Dosing: Infants and Children

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Pharmaceutical Poisoning: Treatment Strategies

Pharmaceutical Poisoning: Treatment Strategies

Treatment strategies for poisoning are a critical aspect of emergency medicine, focusing on preventing the absorption of toxins and enhancing their elimination. When a poisoning incident occurs, the first response is to halt exposure and decontaminate the patient, particularly through gastrointestinal (GI) methods if the poison was ingested.Gastrointestinal Decontamination Techniques:Activated charcoal is the cornerstone of GI decontamination. It works through adsorption, binding the toxin to...

Summary

A child experienced a gentamicin overdose but recovered fully after prompt hemodialysis. This case highlights hemodialysis as an effective treatment for high gentamicin levels, preserving renal and auditory function.

Background:

Gentamicin is a critical antibiotic for severe infections but carries risks of nephrotoxicity and ototoxicity.
Accidental overdoses can lead to dangerously high serum concentrations.
Monitoring and timely intervention are crucial for managing gentamicin toxicity.

Observation:

A 14-month-old girl received a significant gentamicin overdose (56 mg/kg).
Despite normal baseline renal function, serum gentamicin levels reached 89 mg/L.
The patient presented with a unique case of extremely high gentamicin levels in a healthy child.

Findings:

Prompt hemodialysis initiated 4 hours post-administration effectively reduced serum gentamicin levels from 89 mg/L to 3.4 mg/L within 4 hours.
Post-hemodialysis gentamicin levels continued to decline, reaching 2.3 mg/L four hours after treatment cessation.
Three months later, the child exhibited normal renal function (serum creatinine 0.3 mg/dl) and normal hearing bilaterally.

Implications:

This case demonstrates the efficacy of hemodialysis in rapidly clearing gentamicin, even at extremely high concentrations in patients with normal renal function.
Early intervention with hemodialysis may prevent potential long-term adverse effects on renal and auditory health.
Highlights the importance of vigilant monitoring and prompt management strategies for aminoglycoside overdoses.
