Study Notes
Nanoparticles in Drug Delivery
- Primary objective of developing nanoparticles: to achieve site-specific targeting and reduce side effects and toxicity.
Composition of Nanoparticles
- Nanoparticles are primarily composed of lipids, polymers, or metals.
Site-Specific Targeting
- Nanoparticles achieve site-specific targeting by attaching targeting ligands to their surface, which bind to specific receptors on target cells.
- Manipulating surface and particle size characteristics enables passive and active drug targeting, increasing specificity and reducing side effects.
- Site-specific targeting reduces systemic toxicity and increases therapeutic efficacy.
Controlled Drug Release
- Nanoparticles can effectively control or sustain drug release, allowing for tailored pharmacokinetics and pharmacodynamics.
Reducing Side Effects and Toxicity
- Nanoparticles contribute to reducing side effects and toxicity by minimizing off-target effects and decreasing drug accumulation in non-target tissues.
- The characteristic advantage of nanoparticles in drug delivery is their ability to reduce side effects and toxicity while increasing therapeutic efficacy.
Particle Size and Characteristics
- The range of particle size for nanoparticles is 1-100 nanometers.
- Manipulating surface and particle size characteristics is significant in drug delivery, as it enables site-specific targeting and reduces side effects and toxicity.
