Summary
This study introduces a molecular communication model for targeted drug delivery (TDD) using nanocarriers. The model enhances drug delivery to sites lacking specific trigger stimuli, improving therapeutic outcomes.
Area of Science:
- Biomedical Engineering
- Nanotechnology
- Pharmacokinetics
Background:
- Liposomes are versatile nanocarriers for targeted drug delivery (TDD).
- Effective TDD relies on stimuli-responsive drug release at target sites.
- Challenges exist for TDD at sites lacking significant trigger stimuli.
Purpose of the Study:
- To present a molecular communication-based TDD model.
- To address drug delivery to sites with or without trigger stimuli.
- To provide analytical expressions for delivered drug concentration.
Main Methods:
- Developed nanotransmitter and nanoreceiver models for molecular communication.
- Utilized a compartmental pharmacokinetics model for nanocarrier transport.
- Investigated drug delivery effectiveness on tissue surfaces.
Main Results:
- The proposed model enables TDD to multiple sites, including those without trigger stimuli.
- Analytical expressions for delivered drug concentration were derived.
- Model effectiveness was evaluated based on various design and environmental parameters.
Conclusions:
- Molecular communication offers a novel approach for TDD.
- Model performance is sensitive to nanocarrier design and microenvironment characteristics.
- This framework advances TDD strategies for challenging therapeutic targets.

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.

Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells.

01:23Modified-Release Drug Delivery Systems: Classification
233
Modified-release drug delivery systems improve drug efficacy and minimize side effects by controlling the rate and location of drug release. These systems fall into three categories: rate-programmed, stimuli-activated, and site-targeted.Rate-programmed systems release drugs at a predetermined rate, maintaining consistent therapeutic levels and reducing fluctuations that could lead to toxicity or subtherapeutic effects. These systems use polymeric matrices, reservoir-based designs, or osmotic...

01:24Cellular Membranes and Drug Transport
2.0K
Drugs must traverse multiple biological barriers, such as multi-layered skin, single-layered intestinal epithelium, and the plasma membrane, to reach their target sites within the body. The plasma membrane, a highly structured composite of phospholipids, carbohydrates, and proteins, is the cell's protective boundary, facilitating selective substance exchange.
Phospholipids arrange themselves into a bilayer, with hydrophilic heads oriented outward and hydrophobic tails facing inward.

11.2K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

1.5K
Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...
