Silicone Elastomers for Controlled Drug Delivery Systems

The engineering of drug delivery systems has allowed for specific targeting and controlled release of drugs that are introduced into the body resulting in more desired therapeutic effects. Silicones can be used in the manufacturing of drug delivery device applications due to their ability to store and release drugs within the body.

  • A wide range of applications and development of drug delivery systems can include diabetes management, contraception, HIV/AIDS prevention, chronic pain management, cardiology, oncology, and central nervous system health, etc.
  • Elkem Silicones is committed to participating in advanced medical innovations like drug delivery and implantable devices. In addition to a comprehensive series of Silbione™ Biomedical M series Liquid Silicone Rubber (LSR) and High Consistency Rubber (HCR), which support the long-term implantable device applications, Elkem offers the Silbione™ Biomedical LSR D series that supports the drug delivery applications.
  • These silicone materials are manufactured in an ISO 9001 registered facility, in controlled environments under GMP principles. Type IV Drug Master Files (DMF) have been filed at FDA.
  • Elkem routinely works with customers to provide custom formulation development projects as many of the specific drug molecules may require customization of silicone elastomer for robust controlled release.
