Comprehensive Services for Liposomal Transdermal Drug Delivery System Development

At BOC Sciences, we provide specialized services tailored to the development of liposomal transdermal drug delivery systems (TDDS), aimed at overcoming the unique challenges of dermal drug penetration. Our comprehensive suite of services is designed to support the preclinical phases of transdermal formulation development, focusing on optimizing liposomal characteristics to enhance drug delivery efficiency through the skin barrier.

Custom Liposomal Formulation Design for Transdermal Delivery

  • Design and Production of Liposomes and LNPs for Transdermal Delivery

We develop unilamellar, multilamellar , and deformable liposomes that enhance skin permeation. Depending on the drug's physicochemical properties, we carefully select lipid compositions such as phospholipids , cholesterol , and surfactants to create a liposomal formulation that facilitates deep dermal or epidermal penetration while minimizing skin irritation. Special formulations like ethosomes, transfersomes, and ultradeformable liposomes are engineered for enhanced skin absorption and retention.

Whether the drug is hydrophilic, lipophilic, or amphipathic, our liposomal formulations are designed to effectively encapsulate a broad range of compounds, including small molecules, peptides, nucleic acids, and biologics. For each API, we choose the optimal lipid composition to ensure high encapsulation efficiency and sustained release over extended periods.

  • Customization for Specific Delivery Needs

Our formulations can be optimized for controlled release, localized action, or long-lasting dermal retention. Whether the goal is to enhance the absorption of drugs for local skin treatment, systemic therapy, or targeted therapy (e.g., in dermatological or oncology applications), we tailor the liposome properties accordingly.

In Vitro and Ex Vivo Skin Permeation and Retention Testing

Accurate skin permeation and retention testing are critical to ensuring the success of a liposomal transdermal delivery system. We provide extensive in vitro and ex vivo skin models to assess and validate the efficacy of liposomal formulations:

  • Ex Vivo Porcine and Rat Skin Models

We utilize porcine skin and rat skin (commonly used for transdermal delivery studies) to evaluate the penetration profile, drug absorption, and retention of liposomal formulations. These animal models mimic human skin in many ways and provide highly relevant data for the permeation and deposition of liposomes within different skin layers.

  • Franz Diffusion Cell Studies

Our Franz diffusion cells, equipped with suitable membrane models, enable us to quantitatively assess flux rates, cumulative drug delivery, and skin deposition over time. These studies are pivotal for understanding the release kinetics and penetration depth of liposomal drugs, ensuring targeted delivery for the intended application.

  • Quantification of Drug in Skin Layers

Post-testing, we employ high-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS) to accurately quantify drug levels in stratum corneum, epidermis, dermis, and subcutaneous layers, offering a detailed pharmacokinetic profile.

At BOC Sciences, our liposomal transdermal drug delivery system development services are tailored to meet the unique needs of your project, whether it is for dermatological, oncological, or cosmetic applications.

Step-by-Step Process of Liposomal Transdermal Drug Delivery System Development

Our development process for liposomal transdermal drug delivery systems follows a systematic approach designed to ensure precision and consistency at every stage.

1. Initial Consultation and Requirement Analysis: Our team of experts collaborates with clients to understand the specific requirements for the transdermal system, including drug properties, target therapeutic areas, and desired release profiles.

2. Liposome Formulation Development: Based on the drug's chemical characteristics, we select and optimize the lipid components to create the ideal liposomal formulation. The formulation is tested for encapsulation efficiency, particle size, and stability under various conditions.

3. Liposomal Characterization and Evaluation: The liposomal formulations undergo rigorous characterization to determine their size distribution, surface charge, and encapsulation efficiency. Stability studies are performed to assess long-term shelf-life and storage conditions.

4. In Vitro Penetration Testing: We use various animal skin samples to evaluate the ability of the liposomal formulations to penetrate the skin. Penetration data helps to refine the formulation for maximum efficacy.

5. Optimization and Scale-Up: Once a suitable formulation is identified, we optimize the liposomes for enhanced drug release profiles. We then scale up the production to meet larger preclinical and clinical trial needs.

6. Safety and Toxicity Testing: Preclinical toxicity testing is conducted to ensure the safety of the liposomal formulation. Our extensive experience in safety evaluations guarantees that the formulations comply with regulatory standards.

Benefits of Our Liposomal Transdermal Drug Delivery System Development

Applications of Our Liposomal Transdermal Drug Delivery System Development

Liposomal transdermal systems have demonstrated broad utility across multiple therapeutic areas, particularly for drugs that benefit from localized delivery or require avoidance of first-pass hepatic metabolism.

Pain Management

Liposomal TDDS enables sustained, localized delivery of non-steroidal anti-inflammatory drugs (NSAIDs), local anesthetics (e.g., lidocaine), or opioids (e.g., buprenorphine), reducing peak plasma concentrations and systemic toxicity. This is particularly valuable for models of chronic pain, arthritis, or musculoskeletal disorders, where targeted transdermal application improves therapeutic outcomes and reduces the need for invasive administration routes.

Hormonal Therapies

Liposomal formulations facilitate the controlled transdermal release of sex hormones such as estrogen, progesterone, and testosterone. In preclinical models of hormonal imbalance, menopause, or hypogonadism, these systems offer stable plasma concentrations over extended periods, mimicking physiological rhythms more effectively than oral or injectable forms. BOC Sciences offers customized liposome designs to optimize hormone encapsulation efficiency and skin absorption kinetics.

Antimicrobial and Antifungal Delivery

Skin and mucosal infections can benefit significantly from liposomal TDDS. Our systems have been employed for the delivery of agents like acyclovir (antiviral), clotrimazole (antifungal), and mupirocin (antibacterial), achieving high local drug concentrations at the infection site with minimal systemic exposure. This is especially critical in drug-resistant infections where localized action reduces resistance pressure.

Wound Healing and Regenerative Medicine

Delivering growth factors (e.g., EGF, VEGF), peptides, or anti-fibrotic agents via liposomal TDDS allows for precise control over dermal remodeling and tissue repair. These systems are extensively used in studies involving diabetic wounds, surgical recovery, and skin graft regeneration. Our expertise ensures optimal encapsulation of sensitive biomolecules with preserved bioactivity.

Dermatology and Cosmeceuticals

In the realm of dermatological science and cosmetic research, liposomal carriers are instrumental in enhancing the delivery of active ingredients such as retinoids, niacinamide, hyaluronic acid, and antioxidants. These formulations penetrate deeper skin layers, improving efficacy in studies focused on hyperpigmentation, photoaging, and skin barrier repair. BOC Sciences provides formulation strategies for both hydrophilic and lipophilic compounds to maximize dermal bioavailability.

Vaccines and Immunotherapy

Liposomes serve a dual role in vaccine development—as carriers and immunological adjuvants. When applied transdermally via microneedle-assisted or passive delivery systems, liposomal vaccines stimulate potent immune responses without the need for intramuscular injection. BOC Sciences supports the development of transdermal vaccine delivery systems for peptide antigens, DNA vaccines, and protein-based immunotherapeutics in preclinical settings.

Supplementary Knowledges: Transdermal Drug Delivery

Examples of transdermal drugs

Transdermal systems have been successfully used to deliver a range of therapeutic agents. Notable examples include fentanyl for chronic pain management, nicotine for smoking cessation, estradiol and testosterone for hormone replacement therapy, clonidine for hypertension, and scopolamine for motion sickness. Emerging candidates include insulin analogs, peptides, and anti-inflammatory agents, which benefit from enhanced bioavailability and patient compliance when formulated with liposomal carriers.

What is the difference between transdermal and topical drug delivery systems?

The key difference lies in the site of action and systemic exposure.

  • Topical delivery is intended for localized effects on the skin or mucous membranes (e.g., anti-fungal creams, corticosteroid ointments).
  • Transdermal delivery is designed to deliver the drug across the skin barrier into systemic circulation for therapeutic effects throughout the body. Liposomal systems enhance both routes, but in transdermal applications, they are specifically engineered to penetrate deeper skin layers and bypass the stratum corneum efficiently.

What are the problems with transdermal drug delivery?

Several challenges hinder effective transdermal delivery:

  • Stratum corneum barrier: The outermost skin layer resists the penetration of most drug molecules, especially hydrophilic or high molecular weight compounds.
  • Limited drug loading capacity: Only a narrow range of drug types (typically lipophilic and low molecular weight) are suitable without advanced delivery systems.
  • Skin irritation and sensitization: Prolonged exposure or use of penetration enhancers can lead to adverse skin reactions.
  • Variable absorption: Inter-individual differences in skin physiology and hydration levels can affect drug uptake.

Liposomal formulations address many of these issues by improving permeability, modulating drug release, and reducing irritation through biocompatible lipid matrices.
