Alternative Drug Delivery Systems

Drug release, absorption, distribution, and elimination profiles to improve product efficacy and safety, as well as patient convenience and compliance, can be modified through drug delivery technologies. Oral and parenteral are the most common routes of drug delivery, but alternative drug delivery is preferred in many situations. SRI Biosciences has expertise in the development of these specialized drug delivery systems:

  • Nasal formulations

  • Vaginal formulations

  • Polymeric films and microspheres

  • Biodegradable implants

  • Transdermal delivery

  • Transmucosal bioadhesive delivery

  • Nanoparticle drug delivery

  • Gels

  • Ointments

  • Creams

SRI has been working on formulation and delivery approaches to enable currently approved drugs to take advantage of more economical and practical drug delivery technology in an approach sometimes referred to as “IV to PO.” We have had great success in reformulating IV drug products into oral dosage forms.
