Summary
Developing affinity-based drug delivery systems offers a promising strategy for treating central nervous system (CNS) disorders by enabling targeted drug release. These advanced systems leverage molecular interactions for enhanced therapeutic efficacy in the brain and spinal cord.
Area of Science:
- Neuroscience
- Biomaterials Science
- Pharmacology
Background:
- Central nervous system (CNS) disorders present significant therapeutic challenges due to their complexity.
- Current drug delivery methods often fail to achieve targeted, localized release in the brain and spinal cord, limiting clinical translation.
Purpose of the Study:
- To review the potential of affinity-based drug delivery systems for CNS disorders.
- To explore methods for enhancing drug delivery and efficacy within the CNS.
Main Methods:
- Examination of various affinity-based delivery approaches: hydrogels, micro- and nanoparticles, and functionalized biomaterials.
- Analysis of design considerations for effective affinity-based systems.
Main Results:
- Affinity-based systems demonstrate potential for local, sustained release of therapeutic agents like proteins and growth factors.
- Biochemical modification and optimization of physical/chemical properties are key to improving therapeutic outcomes.
Conclusions:
- Affinity-based drug delivery systems hold significant promise for overcoming CNS treatment challenges.
- Careful design and optimization are crucial for developing effective systems for targeted CNS drug delivery.

01:29Drug Delivery: Parenteral Route
460
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...

01:26Targets for Drug Action: Overview
6.1K
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...

01:23Factors Affecting Drug Distribution: Physiological Barriers
195
Drug distribution in the body is intricately regulated by various physiological barriers that control the passage of substances. These include the capillary endothelial barrier, the blood-brain, blood-cerebrospinal fluid, blood-placental, and blood-testis barriers.
The capillary endothelial barrier allows only smaller molecules below 600 Da (Daltons) to pass through. It also restricts drugs like heparin that are bound to blood components, limiting their movement within the bloodstream.

01:22Drug Delivery: Miscellaneous Routes
333
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...

01:16Drug Delivery: Overview
281
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...

01:23Mechanisms of Drug Absorption: Paracellular, Transcellular, and Vesicular Transport
491
Drugs need to permeate cell membranes to reach their target sites after administration. Orally administered drugs must transcend intestinal epithelial membrane barriers to infiltrate the systemic circulation. Drugs with a molecular weight of less than 500 Daltons diffuse through gaps between neighboring cells, called paracellular pathways.
However, most drugs use the transcellular route, traversing directly through the cell membranes via two mechanisms: passive and active transport. Passive...
