Abstract

Insights

Reducing antibiotic use is a public health priority. This study identified shortest effective antibiotic treatment durations for common infections, aiding antimicrobial stewardship efforts.

Area of Science:

  • Infectious Diseases
  • Antimicrobial Stewardship
  • Public Health

Background:

  • Reducing antibiotic consumption is a key public health goal.
  • Shortening antibiotic treatment duration is a strategy to decrease overall consumption.
  • Current guidelines often recommend a 1:2 ratio for treatment durations.

Purpose of the Study:

  • To review and recommend the shortest feasible antibiotic treatment durations for common infections.
  • To support antimicrobial stewardship initiatives by optimizing treatment lengths.
  • To address the public health priority of reducing antibiotic use.

Main Methods:

  • Systematic literature search of guidelines in French and English on PubMed.
  • Analysis of articles published up to August 31, 2015.
  • Focus on identifying clinically supported shortest treatment durations.

Main Results:

  • Shortest treatment durations were identified for numerous infections, including respiratory tract, bloodstream, endocarditis, meningitis, intra-abdominal, urinary tract, reproductive tract, bone and joint, skin/soft tissue, and febrile neutropenia.
  • Detailed findings were presented in tables.
  • The study synthesized evidence for optimizing antibiotic courses.

Conclusions:

  • Further well-designed studies are needed to evaluate treatment durations for certain common infections.
  • The Recommendation Group of the French Infectious Diseases Society (SPILF) proposes specific research directions.
  • Evidence-based recommendations for shorter antibiotic courses can contribute to antimicrobial stewardship.

Pharmacokinetic–Pharmacodynamic Relationship: Influence of Elimination Half-Life on Effect Duration

Drug elimination from the body primarily occurs through metabolic and excretion pathways. Hepatic metabolism transforms lipophilic drugs into hydrophilic forms for excretion, typically via enzymatic processes classified as phase I (modification) and phase II (conjugation). Renal excretion eliminates drugs and metabolites through filtration and secretion in the kidneys. Impairment in liver or kidney function can hinder these processes, delaying drug clearance and extending the drug’s...

Combined Effects of Drugs: Synergism01:27

Combined Effects of Drugs: Synergism

Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.
Such synergistic combinations...

Pulmonary Tuberculosis V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Dosage Interval and Administration Route: Determination Methods

A medication’s effectiveness largely depends on its appropriate dosage and the route of administration. Dosage ensures that a sufficient drug concentration is maintained in the bloodstream to elicit the desired therapeutic effect without causing toxicity. The route of administration affects the drug's bioavailability, rate of absorption, and onset of action, which are crucial for achieving optimal therapeutic outcomes. Drug dosage calculations are critical to tailoring therapy to...

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...

Pharmacokinetic–Pharmacodynamic Relationship: Duration of Dose-Effect Relationship

For drugs producing a quantal response, onset occurs when plasma concentration reaches a minimum effective level (Cmin). The drug's action duration depends on how long the plasma concentration remains above Cmin.Two primary factors influence this duration: dose size and the rate of drug removal from the action site. Both depend on the drug's redistribution to poorly perfused tissues and elimination processes. A larger dose promotes rapid onset and prolongs the effect's duration.Consider a...
