まとめ

患者の耐性を考慮した新しいメタドン再開プロトコルは,安全性や保持に影響を与えることなく,より高い用量をもたらしました. このアプローチはオピオイド使用障害の治療結果を改善する可能性があります.

科学分野:

依存症医学
薬理学について
公衆衛生

背景:

オピオイド治療プログラム (OTP) では,メタドンの投与を忘れた後に再開することが一般的です.
現在のガイドラインでは,耐性維持を無視して,多くの場合,投与量を大幅に減らすことを推奨しています.
これは患者の安全性と治療の有効性に影響を及ぼします.

研究の目的:

新しいメタドン再開プロトコルの安全性と治療継続性を評価する.
個別化された用量調整が患者の結果に与える影響を評価する.
新しいプロトコルと以前の標準的な慣行を比較する.

主な方法:

公的OTPでの2022年プロトコル変更前の (2021) と後の (2023) 患者を比較したコホート研究.
新規のプロトコルには患者による非処方オピオイド使用と個別評価が含まれています
治療の継続も測定された.

主要な成果:

新しいプロトコルでは,再開時に小量の減少が認められた (3. 4% vs 32. 8%).
治療後のグループでは7日以内に緊急治療室への訪問が著しく減少した (6. 1% vs 9. 5%).
90日間の死亡率と治療継続率は,患者と臨床医の満足度が高かった.

結論:

中間オピオイド耐性を考慮した個別化されたメタドン再開プロトコルは安全で有効です
このアプローチは,患者の安全性や治療継続を損なうことなく,より高い再開用量を可能にします.
長期的な治療結果の改善を確認するには,さらなる研究が必要である.

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...

Opioid Analgesics: Synthetic and Semisynthetic Opioids

421

Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

Phase II Reactions: Methylation Reactions

339

Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...

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...
