We enable our global clients to accelerate therapeutic delivery optimization, bioavailability enhancement, and pharmacokinetics improvement using liposome-based vectors across various routes of administration and disease targets.

Step-by-Step Process of Liposome-based Drug Delivery Solutions

Our approach to liposome-based drug delivery systems is methodical and tailored to each project's needs. The process involves several critical steps, each designed to ensure optimal formulation and performance.

1. Initial Consultation and Requirement Analysis

We begin by understanding your specific drug delivery goals and therapeutic needs. This phase includes reviewing the drug's characteristics, desired release profile, and target tissue.

2. Liposome Design and Formulation

Based on the drug's properties, our team designs the optimal liposome formulation, selecting the appropriate lipid composition, size, charge, and encapsulation method.

3. Liposomal Encapsulation

This critical phase involves the efficient encapsulation of your therapeutic payload—whether hydrophilic, lipophilic, or amphiphilic—into liposomal carriers. We optimize encapsulation based on solubility, pH gradients, and loading techniques (e.g., passive vs. active loading), ensuring high encapsulation efficiency and minimal drug leakage.

4. Surface Modification and Targeting

For targeted drug delivery, we modify the surface of the liposomes with ligands, antibodies, or polymers to enhance cellular uptake by specific receptors.

5. In Vitro & In Vivo Evaluation

After formulation, we conduct in vitro tests to evaluate the stability, drug release kinetics, and efficacy of the liposomal system. We perform preclinical studies to assess the pharmacokinetics, biodistribution, and therapeutic efficacy of the liposomes in relevant animal models.

6. Scale-Up and Manufacturing Feasibility

Pilot-scale production under cGMP-like conditions (for preclinical supply), maintaining reproducibility and quality standards.

7. Regulatory Support Documentation

Full characterization dossiers to facilitate Investigational New Drug application submissions where required.

Applications of Our Liposome-based Drug Delivery Solutions

Liposome-based drug delivery systems offer transformative solutions across a variety of therapeutic areas, providing unique benefits that enhance the efficacy, precision, and safety of drug formulations. The versatility of liposomes as drug carriers allows them to be tailored for specific needs, resulting in a broad spectrum of applications, particularly in complex diseases that require targeted and controlled delivery.

Targeted Cancer Therapy

Liposomes enable targeted delivery of chemotherapeutic agents directly to tumor sites, reducing systemic toxicity. By modifying their surface, liposomes can be designed to bind specifically to cancer cells.

• Example: Liposomal formulations like Doxil, containing doxorubicin, deliver higher drug concentrations to tumors, minimizing side effects.

Gene and RNA Delivery

Liposomes efficiently deliver DNA, RNA, and siRNA, protecting these fragile molecules from degradation. This makes them ideal for gene therapies and mRNA vaccine delivery.

• Example: Liposomes are used to deliver mRNA vaccines, ensuring stability and effective antigen presentation.

Central Nervous System (CNS) Drug Delivery

Liposomes can cross the blood-brain barrier (BBB), delivering drugs directly to the brain, improving treatments for neurological disorders like Alzheimer's and Parkinson's.

• Example: Liposomal formulations for neuroprotective agents improve brain bioavailability, enhancing efficacy while reducing side effects.

Immunotherapy and Vaccine Delivery

Liposomes can cross the blood-brain barrier (BBB), delivering drugs directly to the brain, improving treatments for neurological disorders like Alzheimer's and Parkinson's.

• Example: Liposomal formulations for neuroprotective agents improve brain bioavailability, enhancing efficacy while reducing side effects.

Anti-inflammatory and Pain Management

Liposomes can deliver anti-inflammatory drugs directly to the site of action, offering sustained release and reducing side effects commonly associated with systemic administration.

• Example: Liposomal formulations of NSAIDs like diclofenac provide targeted pain relief with reduced gastrointestinal irritation.

Cardiovascular Drug Delivery

Liposomes target vascular tissues, improving the delivery of cardiovascular drugs like statins and anticoagulants, reducing systemic side effects.

• Example: Liposomal formulations of statins enhance bioavailability, enabling more efficient treatment of heart disease with fewer side effects.

FAQs – Insights about Our Liposome-based Drug Delivery Solutions

What types of drug molecules can be encapsulated in liposomes?

Liposomes can encapsulate both hydrophilic and hydrophobic drugs, such as small molecules, peptides, nucleic acids (e.g., mRNA, siRNA), and proteins. This versatility enables their use in a broad range of drug development programs, from oncology to gene therapy.

Can BOC Sciences customize liposome formulations for specific drug delivery needs?

Yes. We offer fully customized liposome formulation services based on drug physicochemical properties, target tissue, and delivery route. Our formulations can be tailored for parameters such as particle size, surface charge, PEGylation, targeting ligands, and release kinetics.

Can liposomes be engineered for targeted delivery to specific tissues or cells?

Yes. Using ligand-functionalized liposomes (e.g., antibody, peptide, sugar moieties), we design delivery systems that recognize and bind specific receptors overexpressed on target cells—ideal for cancer, CNS, and immune therapies.
