Innovative Drug Delivery Technologies

Drug delivery is the action of administering a pharmaceutical drug into the body for a therapeutic effect through various routes. Drug delivery technologies modify drug release profiles, pharmacokinetic parameters for the benefit of improving product efficacy and safety, as well as patient convenience and compliance. Conventional routes cannot deliver compounds such as proteins, antibodies, vaccine and gene based drugs because these routes are susceptible to enzymatic degradation or cannot be absorbed into the systemic circulation efficiently due to large molecular size and charge issues.

Technologies include digitally controlled needle-free devices, sustained and controlled transdermal delivery technology, fiber-based technology for implantable devices, targeted penetration matrix technology for non-invasive delivery and location-specific nano devices for chemotherapy delivery. Many innovative technologies for effective drug delivery have been developed, including implants, nanotechnology, cell and peptide encapsulation, micro fabrication, chemical modification.
Biotechnology advances are leading to develop medications that can target diseases more effectively and precisely. If a drug is more targeted, the chance of triggering drug resistance is lower, a cautionary concern surrounding the use of broad-spectrum antibiotics.

Nanotechnology delivers drugs to targeted cells using nanoparticles. The overall drug consumption and side-effects are lowered significantly by depositing the active drug in the particular site and preventing administration of booster doses. Nanotechnology based devices are less invasive, can be safely implanted inside the body and biochemical reaction times are much shorter.
