Improving drug solubility is crucial for new active pharmaceutical ingredients (APIs). Nanoparticle engineering, particularly top-down approaches, offers significant advantages over traditional micronization for enhancing drug dissolution rates and market viability.

Area of Science:

  • Pharmaceutical Science
  • Materials Science
  • Chemical Engineering

Background:

  • Increasing numbers of new active pharmaceutical ingredients (APIs) face market entry challenges due to poor solubility.
  • Traditional methods like salt formation and cosolvents offer limited improvement for low-solubility compounds.
  • Mechanical reduction of particle size (micronization) is a standard but often insufficient technique.

Purpose of the Study:

  • To review and compare bottom-up and top-down techniques for nanoparticle production.
  • To highlight the advantages of top-down approaches for industrial-scale drug solubility enhancement.
  • To discuss specific top-down methods and their impact on pharmaceutical usability.

Main Methods:

  • Review of existing literature on drug particle size reduction techniques.
