Surinerts are inert cores made following Good Manufacturing Practices for bulk pharmaceutical excipients


Inert microgranules made of pharmaceutical grade sucrose and corn starch

Pharmaceutical companies use Surinerts as cores in sustained and controlled release formulations in solid-oral dosage forms.


Project Design

  • Surface: roughness and sphericity to ensure uniform application; no porosity, cracks or holes;
  • Reproducibility: Reliable and reproducible uniformity for batch-to-batch consistency;
  • Different Particle sizes: for different pharmaceutical dosages;
  • Minimum humidity content;
  • Low friability and hardness to withstand fluid bed processing;
