Medical Applications: Nanoparticle for Drug Administration
Nanoparticles Unique Properties in drug administartion:
- Improved efficacy of drugs
- Extension of drug half-life
- Reduced toxicity
- Active or passive targeting
- Product lifecycle management
- Improved solubility of drugs
The Food and Drug Administration (FDA)-approved oral, local, topical, and systemic (e.g., intravenous) administration methods for the delivery of nanoparticles:
- oral delivery of particles has been approved clinically for imaging applications (e.g., Gastromark),
- local delivery of particles has been widely used in the clinic as depot delivery systems for the extended delivery of a variety of biologics including peptides and other small molecules (e.g., DepoCyt),
- topical application of particles has been approved clinically to increase penetration of biologics across the skin barrier (e.g., Estrasorb),
- systemic delivery of particles has been approved clinically for treating a variety of cancers (e.g., Doxil) (Anselmo, 2016)
