Area of Science:

  • Pharmaceutical Technology
  • Materials Science

Background:

  • Traditional pelletization methods can be time-consuming and complex.
  • There is a need for efficient and adaptable manufacturing processes for pharmaceutical dosage forms.

Purpose of the Study:

  • To develop and optimize a novel hot melt direct pelletization method.
  • To characterize the process for producing flexible pellet dosage forms.

Main Methods:

  • Utilized statistical experimental design for process screening and optimization.
  • Employed carnauba wax (CW) and HPMC K100M mixtures with melted Gelucire 50-13 as a binding material (BM).
  • Investigated factors including spray rate, BM quantity, and powder feeding rate.

Main Results:

  • Successfully developed and optimized a fast and efficient hot melt pelletization process.
  • Identified key process parameters influencing pellet formation.
  • Demonstrated the reproducibility and predictability of the novel method.

Conclusions:

  • The novel hot melt direct pelletization is a viable, agile manufacturing approach.
  • Enables the production of flexible pellet dosage forms with tunable release rates (immediate to modified).
  • Offers a predictable and efficient alternative for pharmaceutical manufacturing.
