Pharmaceutical Inert Cores
for Drug Layering
Pharmaceutical-grade inert cores with controlled particle size, high sphericity and low friability, designed to support reliable drug layering and coating processes
Inert Cores for Pharmaceutical Drug Layering
SURINERTS® provides pharmaceutical inert cores designed to support subsequent drug layering and functional coating processes.
High surface uniformity, controlled particle size distribution and mechanical resistance help ensure reliable processing and consistent performance throughout pharmaceutical manufacturing.
SURINERTS® supplies inert cores and excipients only and does not perform API drug layering activities on customer products.
Key Characteristics for Drug Layering and Coating
-
High Sphericity and Surface Uniformity
Roughness and sphericity to ensure uniform drug layering and coating; no porosity, cracks or holes -
Outstanding Mechanical Strength and Low Friability
Minimizing particle breakage during handling, transportation and high-shear manufacturing processes. -
Controlled Particle Size
A wide range of standard and special particle sizes is available to support different drug layering and coating requirements. -
Reliable Batch-to-Batch Reproducibility
Controlled manufacturing processes support consistent physical characteristics and reliable pharmaceutical processing.
SURINERTS® Inert Core Solutions
Pharmaceutical Sugar Spheres
SURINERTS® Sugar Spheres are neutral inert pellets manufactured using pharmaceutical-grade sucrose and maize starch under controlled production conditions.
They are available in standard and special sizes from 300 µm to 1700 µm, with additional customized sizes available according to project requirements.
Tartaric Acid Pellets
SURINERTS® 100% Tartaric Acid Pellets are GMP-manufactured inert cores designed for pharmaceutical use.
They are designed to support dissolution enhancement of poorly soluble basic APIs through localized acidification and are suitable for multiparticulate drug delivery systems requiring acidic micro-environment control.
Standard and special sizes are available from 300 µm to 1000 µm, with customized sizes evaluated according to project requirements.
Particle Size Selection and Formulation Compatibility
SURINERTS® supports pharmaceutical companies in identifying the most suitable Sugar Sphere or Tartaric Acid Pellet grade according to the required mesh size, application requirements and manufacturing process.
Key parameters considered during technical evaluation include particle size distribution, sphericity, flowability, mechanical resistance and suitability for subsequent drug layering or functional coating processes.
The SURINERTS® portfolio includes standard, special and customized inert core solutions.
