Directly Compressible Excipient for Orally Disintegrating Tablets


Product Features

  • HiSORAD is a state-of-the-art co-processed excipient for orally disintegrating tablets designed to have well-balanced property between oral disintegration time and tablet hardness.
  • Composed of three compendial grade excipients, D-Mannitol, Microcrystalline cellulose and Croscarmellose sodium.
  • Regulatory status: US-DMF filed
  • Before

  • After


  • Excellent compactability
  • Well-balanced tablet property between OD time and hardness
  • High API loading capacity
  • Simple composition

How to use

HiSORAD is developed for direct compression by conventional manufacturing and packaging machineries.
HiSORAD consists of excipients that have already been chosen and processed to design ODTs. In the simplest case,
manufacturers only need to mix HiSORAD with APIs and lubricants before tableting.
As it helps in the formulation of ODTs, HiSORAD can be a time-saving tool for manufacturers.

Tablet Properties (Placebo)

  • High tablet hardness possible even at relatively low compression forces.
    HiSORAD is expected to be suitable for poorly compressible APIs.
  • Placebo tablet with HiSORAD draws water rapidly and disintegrates within 20 seconds.
