Single compartment drug delivery

Area of Science:

• Pharmacology
• Biomedical Engineering
• Drug Delivery Systems

Background:

• Systemic drug administration faces challenges due to similar molecular targets in healthy and diseased tissues.
• Poor drug partitioning and rapid metabolism limit the efficacy of systemic treatments.
• Certain body compartments are inherently difficult to reach with systemically administered drugs.

Purpose of the Study:

• To review drug delivery methods that physically target drugs to specific body compartments.
• To discuss the rationale and examples of single compartment drug delivery for various organs.
• To provide a translational and technological perspective on localized drug administration.

Main Methods:

• Focus on drug delivery methods enabling physical targeting to individual body compartments.
• Review of procedures and devices for direct drug administration.
• Discussion of examples across different development stages, from research to clinical practice.

Main Results:

• Identification of specific compartments (bladder, peritoneum, brain, eye, skin) as key targets for localized drug delivery.
• Overview of diverse approaches and technologies for direct drug administration into these compartments.
• Examples illustrating the progression of single compartment drug delivery from preclinical to clinical applications.

Conclusions:

• Single compartment drug delivery offers a promising strategy to enhance therapeutic outcomes for diseases localized in specific tissues.
• Technological advancements are enabling more effective and targeted drug administration to previously inaccessible or "privileged" body compartments.
• This approach holds significant potential for improving disease management across various medical fields.
