Targeting the intestinal lymphatic system (ILS) with specialized drug vehicles can overcome poor oral bioavailability. This strategy enhances drug absorption and therapeutic efficacy for various clinical applications.
Area of Science:
- Pharmacology
- Drug Delivery Systems
- Gastroenterology
Background:
- Oral drug administration is preferred for patient convenience and safety.
- Poor oral bioavailability due to gastrointestinal challenges limits the effectiveness of many drugs.
- The intestinal lymphatic system (ILS) plays a key role in absorbing and transporting lipids and certain medications.
Purpose of the Study:
- To review targeted drug delivery vehicles for the intestinal lymphatic system (ILS).
- To explore strategies for enhancing oral drug bioavailability and targeted delivery via the ILS.
- To discuss the clinical potential of ILS-targeted therapies, including cancer treatment and oral vaccines.
Main Methods:
- Literature review of studies on ILS structure, physiology, and barriers.
- Analysis of various spatially precise drug vehicles designed for ILS targeting.
- Examination of methods to modulate the ILS for improved drug transport.
Main Results:
- The ILS presents unique opportunities and challenges for drug absorption.
- Targeted vehicles can enhance drug bioavailability and reduce first-pass metabolism.
- Strategies exist to open the ILS 'window' for therapeutic interventions.
Conclusions:
- Targeting the intestinal lymphatic system (ILS) with advanced drug vehicles is a promising strategy.
- These approaches can significantly improve oral drug bioavailability and therapeutic outcomes.
- ILS-targeted drug delivery holds potential for significant clinical advancements, particularly in oncology and vaccinology.

Drug Delivery: Enteral Route
Drug Delivery: Overview
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...
Routes of Drug Administration: Enteral
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,...
Drug Delivery: Miscellaneous Routes
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.
Transdermal patches transport drugs...
Additional Routes of Drug Administration
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...
Routes of Drug Administration: Parenteral
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
