- リネゾリドは多剤耐性グラム陽性感染症の治療に不可欠です.
- 重症患者の薬理学的な変動は,不適切な曝露または毒性を引き起こす可能性があります.
- 治療薬モニタリング (TDM) は,パーソナライズされたラインゾリド投与に不可欠です.
研究 の 目的:
- 集中治療室 (ICU) の患者におけるラインゾリドの極端な個体内 farmakokinetic 変動のケースを記述する.
- 治療用ラインゾリド濃度を達成し,毒性を回避する課題を強調する.

主な方法:
- ヴァンコミシン耐性エンテロコッカス・フェシウム (VRE) による腹膜炎とエンピーエマを治療した66歳のICU患者の症例報告
- リネゾリドの投与量を調整し,中断投与から継続注射 (CI) に切り替える.
- クリアランスと曲線の下の面積を含むラインゾリド濃度と薬動学的パラメータの監視.
主要な成果:
- ラインゾリドの初期標準投与は,サブセラピュティックな濃度をもたらした.
- 連続注入 (CI) は治療的レベルを達成したが,超治療的曝露と毒性をもたらした.
- リネゾリドのクリアランスは非線形排出で,腎機能以外の要因の影響を受けていた.
- PKパラメータは,臨床改善と相互作用する薬剤の離脱後に安定した.
結論:
- リネゾリドは,重篤な疾患において,個体内での有意な薬物動態の変動を示している.
- メカニズムは,CYP2J2のアップレギュレーション,自己抑制,および薬物相互作用を含む可能性があります.

Rational Dosage Regimen: Maintenance Dose and Loading Dose
4.4K
A rational dosage regimen considers a drug's pharmacokinetics, including its absorption, distribution, metabolism, and elimination from the body. By understanding these factors, the appropriate dosage can be determined, and the dosing schedule can be designed to achieve and maintain the desired therapeutic effect while minimizing adverse effects.
In most cases, drugs are administered repetitively or infused continuously to maintain a steady-state concentration in the body. At a steady...

Drug Concentration Versus Time Correlation
1.2K
The plasma drug concentration-time curve is a crucial tool in pharmacokinetics, representing the drug's concentration in plasma at different time intervals post-administration. This curve illustrates the drug's journey from absorption into the systemic circulation, distribution to body tissues, and eventual elimination through excretion or biotransformation.
Two pivotal parameters are the minimum effective concentration (MEC) and the minimum toxic concentration (MTC). The MEC is the...

Drug Concentrations: Measurements
580
Drug concentration is the quantity of a drug present in a biological sample. Measuring drug amounts in biological samples allows the clinician to understand how a drug is absorbed, distributed, metabolized, and excreted. Samples can be obtained through invasive or non-invasive methods. Invasive techniques involve surgical or parenteral interventions to gather blood, cerebrospinal fluid, or tissue biopsy. Conversely, non-invasive approaches provide samples like urine, feces, and saliva.

Drug Dosage Regimen: Overview
3.8K
A drug dosage regimen describes the specific instructions and schedule for administering a drug to a patient. It considers factors such as drug dosage, frequency, route of administration, and duration of treatment. Designing an appropriate dosage regimen for a patient aims to achieve a target drug concentration at the site of action.
Typically, the starting dose and dosing interval are guided by the manufacturer's recommendations based on clinical trials conducted during and after drug...

Time Course of Drug Effect
2.2K
The progression of a drug's impact can be analyzed by examining both the concentration-time course and the effect-time course. The concentration-time course is determined by the drug's half-life and is influenced by factors such as its pharmacokinetics, including absorption, distribution, metabolism, and elimination. The effect of the drug is often related to its concentration in the plasma and is calculated using the maximum drug effect and the plasma concentration that generates 50...
