How It Is Made

Utilizing a unique lyophilization (freeze-drying) process to manufacture finished dosage units, Zydis®  units are produced via a four-stage process:

  • Stage 1 - Mixing 
    • The bulk API is formulated into a liquid solution or suspension.
  • Stage 2 - Filling and freezing
    • The liquid is precisely filled into pre-formed blisters and passed through a specially designed cryogenic freezing process to control the ultimate size of the ice crystals. 
  • Stage 3 - Lyophilization
    • The frozen units are then transferred to large-scale freeze dryers for the lyophilization process. 
  • Stage 4 - Sealing
    • The blisters containing the dried Zydis® units are then sealed via a heat-seal process to protect the product from varying environmental conditions and ensure long-term stability.
