まとめ
ドネペジル (DPZ) の鼻から脳への投与は,血脳障壁を回避することによって,アルツハイマー病 (AD) の治療を改善します. 鼻内投与は脳の薬剤濃度と治療効果を著しく高め,毒性が低い.
科学分野:
- 神経科学
- 薬理学について
- 薬物投与システム
背景:
- ドネペジル (DPZ) は,アルツハイマー病 (AD) の治療に使用されるアセチルコレネステラス (AChE) 阻害剤です.
- 経口用DPZ製剤は,血脳障壁 (BBB) 透過性が悪いため,生物利用性が限られている.
- DPZの直接的な脳標的化を強化するために新しい薬剤投与システムが必要です.
研究 の 目的:
- ドネペジル (DPZ) の鼻から脳 (N2B) への投与システムを検討し分析する.
- アルツハイマー病 (AD) に対する鼻内 (IN) DPZ製剤の有効性と安全性を評価する.
- N2B技術の進歩について議論する
主な方法:
- DPZ製剤に関するN2B研究の体系的レビュー
- 脂質ベースの,固体粒子ベースの,溶液ベースの,ゲルベースの,フィルムベースの様々なIN配給システムの分析.
- 脳への薬物濃度と直接投与比率に関するインビボデータの評価
主要な成果:
- 他の経路と比較して,鼻内 (IN) 投与は15分以内に2倍以上の脳薬剤濃度を達成しました.
- N2Bシステムの直接配送比率は80.32%でした.
- 開発されたDPZ製剤は低毒性とADに対する高い治療効果を示した.
結論:
- 鼻から脳への投与 (N2B) は,アルツハイマー病 (AD) の治療を強化するための非常に有望なアプローチです.
- 鼻内 (IN) 投与はBBBをバイパスし,生体利用性と中枢神経の標的化を改善します.
- N2B製剤の最適化により,粘膜の持続時間とADの治療効果が向上する.

01:18Drug Delivery: Enteral Route
709
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.

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Choosing the appropriate route of drug administration is significantly influenced by two key factors: the therapeutic objectives and the inherent properties of the drug being used.
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...

01:29Drug Delivery: Parenteral Route
827
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

01:16Drug Delivery: Overview
422
The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...

Medications can be administered through the enteral route using liquids, capsules, or tablets.
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...
