Drug Delivery: Parenteral Route

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...

Background:

The central nervous system is protected by the blood-brain barrier (BBB), which regulates homeostasis but limits drug delivery.
This barrier prevents effective treatment for many neurological disorders by restricting molecular transport.
Developing methods to bypass or utilize the BBB is crucial for therapeutic interventions.

Purpose of the Study:

To review the emerging strategy of using nanoparticles for drug delivery across the BBB.
To discuss the structural and physiological characteristics of the BBB relevant to drug transport.
To explore the potential neurotoxicity and future applications of nanoparticles in brain drug delivery.

Main Methods:

Literature review of nanoparticle-based drug delivery systems for the brain.
Analysis of the blood-brain barrier's structure and function.
Discussion of various nanoparticle types used in medical applications.
Evaluation of potential neurotoxicity and future technological advancements.

Main Results:

Nanoparticles represent a promising multifunctional system for enhancing drug transport across the BBB.
Various nanoparticles are being utilized, with ongoing research into their efficacy and safety profiles.
Understanding BBB physiology is key to designing effective nanoparticle delivery systems.

Conclusions:

Nanoparticle-based drug delivery holds significant potential for treating neurological diseases by overcoming BBB limitations.
Further research into nanoparticle safety and efficacy is essential for clinical translation.
Continued investment in this technology is warranted to advance preclinical findings to clinical applications.
