Particle Micronization: A Tool for Enabled Pharmaceutical Formulations

Micronization is an enabling technology providing effective particle engineering for a range of pharmaceutical formulation applications. Micronization of crystalline API is a well-established approach for increasing the surface area, thereby improving the oral bioavailability of drugs whose absorption is dissolution-rate limited, i.e. developability classification system (DCS) IIa drugs. The technology is complementary to other delivery technologies for bioavailability enhancement, such as solid amorphous dispersions, that are applicable to drugs whose absorption is solubility-limited. Other micronization applications for oral delivery include jet milling of API or excipients for microparticle coating applications where particle size distribution is critical. Micronization can be tailored to the optimum particle size, distribution, and fine particle fraction required for specific applications and target product profile desired.
 
Here's what you'll learn as we present:
  • Various applications for particle micronization in pharmaceutical formulations and its use with a range of complementary technologies.
  • The application of micronization to enable specific drug formulations as described through representative case studies.
  • The range of milling process and equipment choice and capabilities, including choice of mill type and process parameters, containment/high potency requirements, and scale-up considerations.
