Summary
Elastic vesicles enhance topical drug delivery by increasing skin penetration. These formulations, including Transfersomes® and ethosomes, improve drug quantity and depth, overcoming the stratum corneum barrier.
Area of Science:
- Pharmacology
- Materials Science
- Dermatology
Background:
- The skin's stratum corneum presents a significant barrier to topical and transdermal drug delivery.
- Low drug diffusion rates limit the efficacy of conventional topical formulations.
- Elastic vesicles offer a promising strategy to enhance drug permeation.
Purpose of the Study:
- To review the role of elastic liposomes in enhancing drug penetration through the skin.
- To elucidate the mechanisms by which elastic vesicles improve transdermal drug delivery.
- To discuss factors influencing the efficacy of elastic vesicle formulations.
Main Methods:
- Review of existing literature on elastic vesicles for transdermal drug delivery.
- Analysis of different types of elastic vesicles, including phospholipid-based (Transfersomes®, ethosomes) and detergent-based formulations.
- Examination of physicochemical properties affecting elastic vesicle performance.
Main Results:
- Elastic vesicles significantly enhance the penetration of both low and high molecular weight drugs into the skin.
- The quantity and depth of drug delivery are improved by using elastic vesicle formulations.
- Physicochemical properties like composition, application parameters, and entrapment efficiency are critical for optimal drug delivery.
Conclusions:
- Elastic vesicles represent an effective approach to overcome the skin barrier for enhanced topical and transdermal drug delivery.
- Understanding the physicochemical properties and mechanisms of action is key to optimizing elastic vesicle-based drug delivery systems.
- Further research into elastic vesicle formulations can lead to improved therapeutic outcomes for various skin conditions.

01:18Transdermal 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...
01:22Drug 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.

01:23Ophthalmic Drug Delivery Systems
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
01:16Drug 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...

01:24Site-Targeted Drug Delivery Systems: Polymeric Carriers
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. Monoclonal...
01:24Modified-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.
