Introduction to Polymers in Novel Drug Delivery Systems:
Polymers are large molecules made of repeating monomers and are essential in NDDS, which enhances drug delivery by optimizing efficiency, targeting, and safety.
Roles in NDDS:
Controlled Release: Polymers can form degradable matrices for sustained drug release.
Targeted Delivery: Surface modifications enable targeting specific cells or tissues.
Protection: Polymers protect drugs from degradation in the body.
Solubility Enhancement: Certain polymers improve solubility of poorly water-soluble drugs.
Advantages of Polymers in NDDS
Controlled Release Profiles:
Polymers can be engineered to provide specific release rates.
Protection of Labile Drugs:
Polymers can shield drugs from degradation in harsh environments.
Targeted Delivery:
Surface modification of polymers allows for targeting specific tissues or cells.
Versatility:
Wide range of polymers enables customization for various drugs and delivery routes.
