Zydis® Bio

The ability through class leading Zydis® ODT technology to deliver fast dissolve formulations of large molecule allergens, viral vaccines, and peptides.

The challenges of oral delivery of proteins & peptides well documented and are not limited to:

  • pH
  • Peptidase & proteolytic enzyme activity
  • Potential interaction with other constituents of GI fluids
  • High molecular weight

Zydis®  Bio sub-lingual delivery overcomes these challenges:

  • Avoids harsh environment of GIT
  • Use of bio-adhesives / absorption enhancers
  • Pre-gastric delivery (e.g. buccal, sublingual, oesophageal)
  • pH relatively neutral (5.5 - 7.2 depending on salivary flow rate)

Benefits of Zydis®  Bio for peptide & protein drugs

  • Potential for sublingual / buccal absorption
  • Solid, unit doses presented in protective pack
  • Low temperature processing minimizes manufacturing losses of labile drugs
  • Solution / suspension dosing achieves good content uniformity for low dose actives
  • Solid dosage form and low water activity aids long term stability
  • Liquid processing facilitates containment of potent drugs in production
How It Is Made

Utilizing a unique lyophilization (freeze-drying) process to manufacture finished dosage units. Zydis® is produced via a four-stage process that includes:

  • 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.

Zydis Manufacturing Process

Catalent Services

Through expert analysis and interpretation of data, our Zydis®  fast dissolve technology team will fully characterize your API and associated Zydis® formulations throughout the development process to provide a robust data package in support of regulatory filings. 

  • Feasibility programs
    • Tailored to meet the known product requirements such as API unit dose
    • Consideration of the relevant API characteristics identified during the technical evaluation of preformulation data 
    • A range of prototype Zydis® formulations prepared under different processing conditions (bench-scale); analytical techniques applied as appropriate to determine the compatibility of a candidate API with the Zydis® technology 
    • Short-term (4 week) accelerated physical stability studies typically undertaken before recommendations for a full development program are made
  • Full in-house analytical and regulatory services 
    • Full characterization of your API and associated Zydis® formulations via expert analysis and interpretation of data throughout the development process to provide a robust data package in support of regulatory filings
  • Smart full-lifecycle management from molecule to market - with Lean efficiency standards 
  • Expert handling and maximization of potent and controlled drugs
  • Bench, pilot, and full-scale cGMP manufacturing in the U.S. and Europe
Catalent Capabilities

We employ the most advanced equipment for our Zydis® fast dissolve preformulations and formulations. The resulting data is used to direct the selection of Zydis® formulators and manufacturing process conditions.

  • Optical microscopy
    • Characterizes the API crystal form and identifies any changes during formulation and processing
  • Freeze-drying microscopy
    • Identifies critical formulation parameters such as collapse temperature, eutectic/glass transition temperature
  • Particle size analysis (laser diffraction)
    • Determines particle size ranges relevant to Zydis® suspension stability for insoluable API
  • Dynamic Vapor Sorption
    • Characterizes moisture sorption properties and physical stability of lyophilized formulation in humidity
  • Characterization of hydrates and polymorphs
  • X-ray powder diffraction (XRPD)
    • Characterizes solid-state phrase behavior
  • Characterization of moisture sorption properties and physical analytical chemistry (HPLC, UV, NIR, FTIR)
    • Chemical analysis of API in support of preformulation studies (e.g., solubility determinations, compatibility testing)
