DrugDeliveryTräger

DrugDeliveryTräger refers to systems designed to transport and release therapeutic agents at specific sites in the body, aiming to improve bioavailability, protect active substances from degradation, and enable controlled or targeted release. These carriers can modify pharmacokinetics, enhance therapeutic effectiveness, and reduce systemic toxicity.

Common classes of DrugDeliveryTräger include lipid-based carriers (such as liposomes, solid lipid nanoparticles, and nanostructured lipid carriers), polymeric carriers (including nanoparticles made from biocompatible polymers like PLGA and PEGylated systems, as well as dendrimers), inorganic carriers (for example mesoporous silica nanoparticles, gold nanoparticles, and iron oxide particles), and biological carriers (such as exosomes or virus-like particles). Additional carrier forms include hydrogels, micelles, and implantable depots that provide local or sustained release.

Targeting and release mechanisms encompass passive approaches, such as the enhanced permeation and retention effect in tumors, and active targeting using ligands that recognize specific receptors. Many systems are designed to respond to stimuli such as pH, enzymes, temperature, or redox conditions to trigger payload release, and some carriers are capable of crossing physiological barriers like the blood–brain barrier.

Advantages and challenges accompany DrugDeliveryTräger. Benefits include improved pharmacokinetics, increased site concentration, reduced off-target effects, and protection of labile drugs. Challenges involve manufacturing complexity, safety and immunogenicity concerns, regulatory classification, scalability, and ensuring reliable, reproducible performance across patients.

Applications span oncology, central nervous system disorders, vaccines, antimicrobial therapies, and other areas where controlled or targeted delivery offers clinical value. Ongoing research explores multifunctional, personalized, and theranostic carrier systems.
