Introduction of Transethosomes Delivery System
Transethosomes are innovative, ultra-deformable nanovesicles designed explicitly for enhanced drug permeation across biological membranes, particularly the skin. These elastic carriers are structurally advanced, combining the benefits of ethosomes (containing high ethanol concentrations) and transferosomes (containing edge activators like surfactants).
Fig.1 Various lipid-based nanocarriers with phospholipid, ethanol, and surfactant.1,4
Structure and Mechanism: The composition—typically phosphatidylcholine, a high concentration of ethanol (20–45% v/v), and an edge activator —confers exceptional elasticity. The ethanol acts as a skin permeation enhancer by fluidizing the intercellular lipids of the stratum corneum, while the edge activator increases the deformability of the vesicle membrane. This synergy allows the nanovesicles, often in the 50 nm to 300 nm range, to squeeze through microscopic pores and tight junctions in the skin barrier that are otherwise impenetrable to rigid carriers. The deformability index is a critical quality attribute we meticulously control to guarantee performance.

| Component | Examples | Uses |
|---|---|---|
| Phospholipids | Lecithin, soybean lecithin, phosphatidylcholine, sunflower phospholipids, Lipoid S 100 | Vesicle forming agent |
| Surfactant | Tweens, Spans, oleyl alcohol, Sodium deoxycholate, oleic acid, diacetyl phosphate, Cetyl Trimethyl Ammonium Bromide | Edge activator |
| Alcohol | Ethanol, isopropyl alcohol | Penetration enhancer |
| Stabilizer | Hydroxypropyl-β-cyclodextrin | Imparts stability |
The clinical and scientific community has recognized the immense potential of these systems. Research highlights the ability of transethosomes to deliver compounds up to 100 times more effectively than conventional liposomes. This enhanced penetration capability is critical for achieving therapeutic concentrations in deep tissues, joints, and systemic circulation, validating transethosomes as a superior platform for transdermal drug delivery.
Applications of Transethosomes Delivery Systems
The unique properties of transethosomes make them ideal for solving complex delivery challenges across multiple therapeutic areas, enabling the non-invasive delivery of both small molecules and biologics.
Transdermal and Systemic Drug Delivery
Localized Disease Treatment
They are exceptionally suitable for local delivery applications where deeper penetration is required. This includes anti-inflammatory agents for conditions like arthritis and psoriasis, or potent antifungal agents for deep-seated dermal and nail infections (onychomycosis).
Delivery of Biologics and Macromolecules
Transethosomes can successfully encapsulate and deliver large, fragile molecules such as therapeutic peptides, proteins, and nucleic acids (siRNA, mRNA). The non-invasive, protective nature of the vesicle is essential for maintaining the structural integrity and bioactivity of these sensitive payloads until they reach the target cells.
Oncology
They are explored for topical and locoregional cancer therapy (e.g., skin cancer or deeper tumor masses), allowing high local drug concentrations while minimizing systemic exposure and associated toxicity.

This study developed Azithromycin-loaded nano-transethosomes (AZM-NTEs) as an improved system for treating bacterial skin infections. The AZM-NTE formulation showed significant enhancements in entrapment efficiency, stability, and ex vivo permeation across rat skin compared to a conventional gel, suggesting superior localized drug concentrations for effective infection management.2,4

Researchers explored the use of Rivastigmine-loaded transethosomes (a drug used to treat Alzheimer's disease) for transdermal patch application. The transethosomes demonstrated enhanced skin permeation and bioavailability ex vivo and in vivo compared to traditional formulations, suggesting a non-invasive, sustained-release alternative to oral administration for neurodegenerative diseases.3,4
What We Can Offer: Comprehensive Transethosomes Services
Transethosomes represent a significant leap forward in vesicular drug delivery, overcoming the limitations of first-generation liposomes and ethosomes. At Creative Biolabs, we specialize in leveraging the unique, highly flexible structure of transethosomes—composed of phospholipids, ethanol, and an edge activator—to achieve deep dermal and systemic penetration of previously challenging compounds.
Our assistance focuses on three core deliverables crucial for project success:
Enhanced Bioavailability
We formulate systems that ensure maximum drug penetration through the stratum corneum, dramatically improving the therapeutic index for topical and systemic treatments.
Payload Protection and Stability
Our proprietary formulation techniques protect fragile payloads, including peptides and nucleic acids, from enzymatic degradation, ensuring the active pharmaceutical ingredient (API) remains intact until it reaches the target site.
Customized Targeting Strategy
We engineer the vesicle surface for specific targeting capabilities, allowing for focused accumulation in localized disease sites like tumors, joints, or fungal infections, minimizing off-target toxicity.
By partnering with Creative Biolabs, you gain access to a validated platform designed to bypass biological barriers and transform your therapeutic candidate into a highly effective, non-invasive drug product.
FAQs
How do these deformable vesicles ensure the drug reaches systemic circulation if they are applied topically?
The ultra-deformable nature of the vesicles, combined with the presence of a permeation enhancer, allows them to navigate the narrow intercellular routes within the stratum corneum (the skin's outermost barrier). Once past this barrier, the vesicles can either release their payload into the dermal layers for localized action or penetrate further into the microcirculation, achieving therapeutic concentrations in the bloodstream for systemic effect.
What are the main stability concerns for this type of system, and how are they managed during development?
The primary concerns relate to physical stability, such as vesicle fusion, aggregation, or leakage of the encapsulated drug. Stability is mitigated by careful selection of the edge activator and lipid components, optimizing the charge (zeta potential), and rigorous storage condition testing. Our formulation scientists engineer the vesicle to maintain a robust yet deformable structure, ensuring longevity and efficacy.
Can these systems successfully encapsulate sensitive macromolecules like peptides or RNA?
Yes, these systems are highly effective for macromolecules. The lipid bilayer provides a protective barrier against enzymatic degradation in the skin and underlying tissues. Furthermore, the encapsulation process is gentle, preserving the structural integrity of sensitive payloads, which is crucial for maintaining their biological activity upon reaching the target site.
How does this technology compare to traditional liposomes for transdermal applications?
Traditional liposomes are generally rigid and accumulate primarily in the upper layers of the skin. This limits their effectiveness for reaching deeper targets or systemic circulation. In contrast, the high elasticity and unique composition of these advanced vesicles enable them to pass through the skin barrier efficiently, resulting in significantly deeper penetration and higher bioavailability.
What initial information is necessary to begin a feasibility study for a new drug candidate using this platform?
To initiate a successful project, we typically require basic physiochemical data on the drug candidate, including its solubility (hydrophilic or hydrophobic), molecular weight, and preliminary stability data. Information regarding the intended therapeutic target and desired route (local or systemic) is also essential for tailoring the optimal vesicle composition.
