Insights

Convection-enhanced delivery (CED) shows promise for brain diseases, but technical challenges hinder clinical success. Future trials will explore improved drug delivery methods for better therapeutic outcomes.

Area of Science:

  • Neurology
  • Neurosurgery
  • Pharmacology

Background:

  • Convection-enhanced delivery (CED) is a promising strategy for treating malignant gliomas and non-neoplastic neurological diseases.
  • Initial clinical trials using CED have not demonstrated survival benefits for new therapeutic agents.
  • Numerous technical and technological challenges impede the widespread adoption and success of CED.

Purpose of the Study:

  • To address the technical and technological limitations of convection-enhanced delivery (CED).
  • To explore novel approaches for optimizing drug distribution and efficacy in neurological treatments.
  • To pave the way for more successful clinical applications of CED.

Main Methods:

  • Simultaneous development of novel technologies and therapeutic agents for CED.
  • Planning of new trials to investigate coinfusion of agents with radiographic tracers.
  • Development of novel catheters designed to prevent backflow and improve drug distribution.

Main Results:

  • While initial clinical trials faced challenges, earlier stage research has identified numerous technical issues.
  • Ongoing research focuses on overcoming limitations in drug delivery and distribution.
  • Planned trials aim to validate new technologies for more reliable CED.

Conclusions:

  • CED remains a viable strategy for neurological diseases, but requires further technological advancement.
  • Addressing technical challenges is crucial for realizing the full potential of CED in clinical settings.
  • Future research and technological innovations are expected to enhance the efficacy and reliability of CED.

Drug Delivery: Parenteral Route01:29

Drug Delivery: Parenteral Route

The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

Additional Routes of Drug Administration

Choosing the appropriate route of drug administration is significantly influenced by two key factors: the therapeutic objectives and the inherent properties of the drug being used.
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
Drug Delivery: Miscellaneous Routes01:22

Drug Delivery: Miscellaneous Routes

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection,  and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs through the...

Modified-Release Drug Delivery Systems: Site-Targeted

Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.
Drug Delivery: Overview01:16

Drug Delivery: Overview

The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the gastrointestinal...
Transdermal Drug Delivery Systems01:18

Transdermal Drug Delivery Systems

Transdermal drug delivery systems (TDDS) enable the controlled release of drugs across the skin into systemic circulation. They are particularly advantageous for drugs with short half-lives or narrow therapeutic indices, as they maintain consistent plasma concentrations and reduce the risk of subtherapeutic or toxic levels.TDDS are categorized into monolithic, reservoir, and mixed systems. Monolithic systems embed the drug in a polymer matrix, where diffusion governs release. Reservoir systems...
