Controlled drug delivery implants enhance treatment efficacy and reduce side effects. This review highlights hybrid bone substitutes, vascular stents, cochlear implants, and in-situ forming implants as key examples.

Area of Science:

  • Biomedical Engineering
  • Materials Science
  • Pharmacology

Background:

  • Controlled drug delivery systems are crucial for optimizing therapeutic outcomes.
  • Conventional drug delivery methods often face challenges with efficacy and side effect management.
  • Implants offer a promising platform for localized and sustained drug release.

Purpose of the Study:

  • To present diverse strategies for controlled drug delivery using implants.
  • To illustrate the advantages of implant-based drug delivery over traditional methods.
  • To showcase innovative applications in bone regeneration, cardiovascular disease, hearing loss, and periodontal treatment.

Main Methods:

  • Review of existing literature and case studies on implantable drug delivery systems.

  • Exemplary presentation of four distinct implant strategies: hybrid bone substitutes, polymer-coated vascular stents, cochlear implants for dexamethasone delivery, and in-situ forming implants for periodontitis.
  • Discussion of the comparative benefits of these advanced systems.

    • Main Results:

    • Hybrid bone substitutes integrate hydroxyapatite and chitosan for enhanced bone regeneration.
    • Vascular stents utilize bio-inspired polymers for targeted drug release, improving cardiovascular treatment.
    • Cochlear implants enable localized dexamethasone delivery to manage inflammation post-surgery.
    • In-situ forming implants provide a minimally invasive approach for periodontitis management.

    Conclusions:

    • Implant-based controlled drug delivery systems offer significant advantages in therapeutic efficacy and safety.
    • The presented strategies represent a fraction of the potential applications for advanced drug-releasing implants.
    • Further development in this field promises to revolutionize medical treatments across various disciplines.
