Parenteral drug delivery systems aim to improve drug safety and efficacy. This review compares three technologies and proposes a novel nanocrystalline ceramic system for advanced drug delivery.

Area of Science:

  • Biomedical Engineering
  • Materials Science
  • Pharmaceutical Sciences

Background:

  • Parenteral drug delivery systems are crucial for enhancing drug safety and effectiveness.
  • Over 30 years of research highlight the need for efficient systems, intensified by current healthcare fiscal constraints.

Purpose of the Study:

  • To compare and contrast three leading parenteral drug delivery technologies.
  • To consider the biophysical constraints influencing these systems.
  • To propose a novel model solution system.

Main Methods:

  • Review and comparative analysis of prodrug/zymogen-like systems, soluble macromolecular systems, and particulate multicomponent systems.
  • Evaluation of biophysical limitations for each technology.
  • Description of a surface-modified nanocrystalline ceramic system.

Main Results:

  • Prodrug systems offer targeted delivery but can have complex activation.
  • Soluble macromolecular systems provide controlled release but may face immunogenicity issues.
  • Particulate systems allow for complex formulations but require precise control over particle characteristics.

Conclusions:

  • No single current technology fully addresses all parenteral drug delivery challenges.
  • Surface-modified nanocrystalline ceramics present a promising platform for next-generation parenteral drug delivery.
  • Further research is needed to optimize the proposed ceramic system for clinical application.
