Mini-tablets are transforming complex drug delivery with unparalleled flexibility in dosing and release profiles. Yet scaling from lab concept to commercial production presents significant technical challenges—from achieving content uniformity at low drug loads to maintaining high-precision filling at manufacturing scale.

At Crystal Pharmatech, our integrated mini-tablet technology platform addresses these complexities head-on, delivering precision-engineered solutions from formulation development through commercial manufacturing.

Engineering Excellence: Our Technical Foundation

Our approach combines science-driven formulation with advanced process engineering:

Precision Formulation Development

We optimize material flow properties and particle size distribution (PSD) to achieve superior content uniformity, consistently meeting specifications at drug loads as low as 0.7%—a critical capability for potent APIs and pediatric formulations.

Compaction Simulation & Quality by Design

Leveraging compaction simulation technology, we optimize lubrication strategies and address high ejection forces early in development. Quality by Design (QbD) principles are embedded throughout our process, ensuring robust, scalable formulations.

Proprietary Equipment Modifications

We don't simply operate equipment—we optimize it. Our proprietary modifications to tableting presses eliminate common scale-up issues including chipping, breakage, and tablet defects, maximizing yield and reducing waste.

High-Precision Capsule Filling

Our filling systems achieve stable, reproducible filling of as few as 4 mini-tablets per capsule, meeting the most stringent industry standards for dose accuracy and consistency.
