Insights

Pediatric emergency departments see age-related differences in oral antibiotic formulations. Tablet/capsule use surpasses suspensions around age 14, informing prescribing for better adherence.

Area of Science:

  • Pediatric Emergency Medicine
  • Pharmacology
  • Clinical Pharmacy

Background:

  • Oral antibiotics are frequently prescribed in the United States.
  • Formulation choice (suspension vs. tablet/capsule) can impact medication adherence and treatment effectiveness in children.

Purpose of the Study:

  • To describe the distribution of oral antibiotic formulation administration among children in the emergency department (ED).
  • To identify the age at which tablet/capsule formulations become more common than suspensions for pediatric patients.

Main Methods:

  • Retrospective single-center study of children (<18 years) discharged from a pediatric ED between 2016-2022.
  • Included encounters prescribed 7 common oral antibiotics in suspension or tablet/capsule forms, excluding specific patient groups.
  • Analyzed antibiotic administration and prescription data to determine formulation preference shifts by age.

Main Results:

  • 12,900 eligible encounters were analyzed, with common diagnoses including ear, throat, and skin infections.
  • Across all antibiotics administered in the ED, the age threshold where tablet/capsule use exceeded suspensions was 14 years.
  • Specific age thresholds varied by antibiotic, ranging from 10 years for trimethoprim-sulfamethoxazole to 16 years for amoxicillin.

Conclusions:

  • Significant age-related differences in oral antibiotic formulation preferences exist in pediatric ED settings.
  • These findings can guide prescribing practices to enhance medication adherence and treatment outcomes.
  • Understanding formulation distribution is crucial for clinical decision support, shared decision-making, and managing medication shortages.

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...

Drug Delivery: Enteral Route01:18

Drug Delivery: Enteral Route

The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...

Routes of Drug Administration: Overview01:22

Routes of Drug Administration: Overview

Drug administration involves delivering drugs to the body through various routes, such as enteral, parenteral, and topical.
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...

Routes of Drug Administration: Parenteral01:25

Routes of Drug Administration: Parenteral

The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
