科学分野:
- 薬の配達とナノテクノロジー
- 材料科学
- 医薬品科学
背景:
- 水性薬,特に抗ウイルス薬は,溶解性や生理学的障壁が悪いため,口腔および肺経路での投与に問題があります.
- 既存の投与方法は,分解,pH,経路時間,またはクリアランスメカニズムにより,治療効果が限られていることが多い.
研究 の 目的:
- 耐水性抗ウイルス剤の持続的な投与のための新しい複合システムを開発する.
- 脂質ナノカプセル (LNC) とヒドロゲルマトリックスを使用してエファビレンズ (EFV) の放出を封じ,制御する.
- シミュレートされた生理学的条件下でシステムの性能を評価し,安全性を評価する.
主な方法:
- 脂質ナノカプセル (LNC) は,エファビレンズ (EFV) を封じ込めるために作られました.
- EFVを積んだLNCはキトーサン/イオタカラーゲンヒドロゲルに埋め込まれ,複合体を作りました.
- 薬剤の溶解性,粒子の大きさ,水凝土の腫れ,封じ込め効率,薬剤の放出運動性,および細胞毒性を評価した.
主要な成果:
- LNCは,水に比べてEFVの溶解性を有意に増加させた (p < 0.0001) で,ドロップレットのサイズが制御された (57. 4 ± 0.5 nm).
- ハイドロゲル複合物は約53%の封じ込み効率と最適化された膨張比率 (約300g/g) を達成した.
- 複合剤からEFVの放出は,未成形薬と比較して異なるpH条件において有意に延長され (p < 0. 0001) 複合剤は細胞相容性を示した.
結論:
- 開発されたLNC-ヒドロゲル複合物は,溶解性を効果的に高め,水害性抗ウイルス薬の放出を制御します.
- このシステムは,粘膜保持の改善と口腔と肺経路による持続的な薬物の投与の可能性を示しています.
- 溶解性が低い薬剤を投与する際の課題を克服し,治療効果を高めるための多用途のプラットフォームです.

In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Poison can be effectively removed from the gastrointestinal (GI) tract through various decontamination procedures.
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.

Diarrhea, a condition marked by frequent loose or watery bowel movements, can be triggered by multiple factors such as viral or bacterial infections, food intolerances, anxiety, medications, and digestive disorders. Symptoms may include abdominal pain, bloating, nausea, and cramping. Severe or prolonged diarrhea can lead to complications like electrolyte imbalances, malnutrition, and dehydration if left untreated.

Bioavailability Enhancement: Drug Stability Enhancement and GI Retention
332
Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions
423
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...

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...
