Controlled Release

Optimized Oral Dose Product Performance

11-VARIETY-S-Catalent-0578 v2

We offer a complete range of controlled release capabilities for tablets, capsule development, and manufacture. As the premier innovator of coated multi-particulate dosage forms and a world leader in the production of coated beads and tablets, we bring years of experience and a network of FDA-compliant facilities to empower your controlled-release success on every level. As we have the capacity to enter into your process at any stage of your product’s lifecycle, we encourage you to consider controlled-release capabilities early in development to proactively increase your product’s value, enhance patient compliance, and maximize your investment. With extensive experience working with potent and complex compounds, we aim to develop controlled-release formulations and processes that are scalable, economical, and easy to manufacture, with the end goal of shortening your time to market. 

Our controlled-release technologies and oral solids capability offers formulation, development, and manufacturing services for both oral solid tablets and hardshell capsules, as well as powders, pellets, beads, and granules. 

Catalent Benefits 

Customers are drawn to our controlled-release expertise and capabilities across the entire lifecycle of products: 

  • Unsurpassed capacity, quality, and formats  
  • Complete range of controlled-release capabilities for tablets, capsule development, and manufacture
  • Added expertise working with potent APIs, nonchlorinated solvents, and all schedules of DEA-controlled substances 
  • Smart lifecycle management at every stage
  • Manufacturing experience and track record, particularly around fluid bed technology

How It Works
  • Controlled-release process
    • Polymers used to coat tablets and beads or drug particles in capsules 
    • Dissolution of coating releases the API over time
  • Controlled-release types 
    • Extended release (XR) or long-acting (LA)
      • Allows for a decrease in dosing frequency that would be necessary if the product were in an immediate dose form
    • Sustained release (SR)
      • Specific amounts of the drug released at timed intervals
    • Delayed or enteric release 
      • API released at a specific point in the body based on pH or other characteristic - depending on the drug profile
      • Drugs released in the intestines formulated to release at a higher pH (more basic) than that found in the stomach (more acidic)
    • Repeat action or pulsed release 
      • Short-term and long-term action created by combining both immediate release and controlled-release products - combined into one dose form 
  • Controlled-release properties
    • Incompatibility barrier
    • Temperature-controlled release
    • Taste making
    • Delayed release
      • Enteric
      • Delayed “dump”
      • Pulse
    • Sustained release
    • Combination profiles via multiparticulates and bilayer tablets
