Area of Science:

  • Nanotechnology
  • Pharmaceutical Sciences
  • Materials Science

Background:

  • Dendrimers are highly branched, synthetic macromolecules with unique three-dimensional structures.
  • Drug delivery systems face challenges in solubility, bioavailability, and targeted delivery.
  • Interactions between drugs and dendrimers offer potential solutions to these challenges.

Purpose of the Study:

  • To review the interactions between drugs and dendrimers.
  • To discuss the applications of dendrimer-drug complexes in pharmaceutical formulations.
  • To highlight the role of dendrimers in enhancing drug delivery.

Main Methods:

  • Review of scientific literature on drug-dendrimer interactions.
  • Analysis of drug entrapment within dendrimer architecture.
  • Examination of electrostatic and covalent complexation methods.

Main Results:

  • Dendrimers can effectively entrap drugs within their structure.
  • Electrostatic and covalent bonding facilitate drug complexation to dendrimer surfaces.
  • These complexes demonstrate enhanced drug solubility and bioavailability.

Conclusions:

  • Dendrimer-drug complexation is a promising strategy for improving drug delivery.
  • Complexes serve as effective vehicles for controlled drug release and targeted delivery.
  • Further research into dendrimer applications in nanomedicine is warranted.
