Microcrystalline Cellulose and Tartaric Acid Pellets

Microcrystalline cellulose and tartaric acid pellets are used to create advanced drug formulations when used as starter cores for drug layering and coating. ACTILLETS™ MCC pellets have low friability, high sphericity, and smooth surfaces for consistent coating. SPI's TAP® tartaric acid pellets can be used to improve the solubility of weakly basic pharmaceutical actives.


SPI Pharma’s ACTILLETS™ microcrystalline cellulose pellets and tartaric acid pellets combine our unique formulation and material science expertise with CELLETS® and TAP® pellet technology from ADD Advanced Drug Delivery Technology Ltd.




SPI has expertise in developing excipient materials and in oral dose development, and we have combined this expertise with MCC and tartaric acid spheres that have superior physical properties.

SPI is a leader in technologies focused to pediatric or patient-friendly dose forms.  ACTILLETS™ and TAP® pellet technology offer a promising solution for the development of oral drug formulations that require precise control over drug release and dosing.

Our MCC and tartaric acid spheres production benefits from the requirements of manufacturing GMP Excipients.
