    Short video providing an overview of Tris Pharma’s proprietary LiquiXR® technology, which was used in the development of Tris Pharma’s branded ADHD products.

What is LiquiXR® Technology?

LiquiXR® drug delivery technology utilizes an ion-exchange resin

  • Ion-exchange resins are made of negatively charged, polystyrene​.
  • Any active moiety that can be protonated and is water-soluble can complex with the ion-exchange resin to form micron-sized drug-resin particles.

Drug-resin particles can be coated with a polymer of varying thickness

  • Portions of drug-resin particles can be coated with an aqueous, pH-independent polymer​
  • Polymer coating applied to drug-resin particles is of varying thickness​
  • These micron-sized, drug-resin particles can be formulated into a variety of dosage forms (tablets, liquids, films, capsules)​

Millions of immediate-release and extended-release particles enable targeted pharmacokinetic profiles​

  • Solid, uncoated particles provide for immediate-release of active drug product.​
  • The variable thickness of the polymer-coated particles allows for programmed, extended release of active drug product. ​

Active drug moiety is released from the drug-resin particles via ion exchange and diffusion​​

  • Once ingested, positively charged ions from the gastrointestinal tract, like sodium, diffuse across the polymer coating and displace the drug from the resin. ​
  • The drug then diffuses back across the coating to the gastrointestinal tract.​​

Extended-release coating of variable thickness slows the diffusion of ions entering and exiting the particles

  • The extent of drug release is based on diffusion rate across the polymer coating which is pH-independent​
  • The mechanism of drug release allows for rapid absorption and sustained plasma levels after once-daily dosing​
  • Technology allows for development of customizable release profiles ​
  • Release profiles can last up to 24 hours​
  • The ion-exchange resins are excreted unchanged in the feces​
