Transdermal Hydrogel Microneedle Patch Development

Inquiry

At CD Formulation, we specialize in the cutting-edge development of transdermal hydrogel microneedle patches. This innovative technology is designed to optimize drug delivery, offering numerous benefits for researchers seeking advanced, non-invasive drug delivery systems.

About Transdermal Hydrogel Microneedle Patches

Hydrogel microneedles are made from cross-linked polymers that absorb interstitial fluid (ISF) upon insertion into the skin, forming a continuous, non-blocking hydrogel tube that can be removed intact. Compared to solid microneedles, hydrogel microneedles are more cost-effective and user-friendly. They also offer higher drug loading capacities than coated microneedles. Drugs can be incorporated either on the base of the microneedles or mixed with polymers, allowing for versatile drug delivery options.

Advantages of Transdermal Hydrogel Microneedle Patches

Leveraging advancements in micro-nano preparation technology, hydrogel microneedles provide an effective subcutaneous, minimally invasive transdermal drug delivery solution. Compared to traditional metal or silicon-based microneedles, hydrogel microneedles—made from biocompatible materials—offer the following benefits:

Our Transdermal Hydrogel Microneedle Patch Development Services

Custom Microneedle Patch Design and Development

Tailored Formulations: We create customized hydrogel and microneedle formulations to meet specific research needs, focusing on optimizing drug delivery and hydrogel properties like hydration, adhesion, and release profiles.
Prototype Development: Our services include developing and testing various prototypes, using different configurations and materials to meet specific application requirements and ensure compliance with regulatory standards.

Hydrogel Gelation Methods

Physical Crosslinking: Ensures biocompatibility and safety without the use of chemical agents.
Electrostatic Crosslinking: Allows for controlled drug release, ideal for specific research needs. However, the drug loading is small, and continuous drug release is required to achieve a considerable effect.
Chemical Crosslinking: Offers enhanced flexibility and precision in the gelation process, ensuring robust hydrogel matrices.

Preparation of Hydrogel Microneedles

Our hydrogel microneedles have a variety of preparation methods, which vary with the hydrogel materials and cross-linking mechanisms. The preparation materials include natural polymers (such as hyaluronic acid, gelatin, agar, etc.) and synthetic polymers (such as polyvinyl alcohol, sodium polyacrylate, methacrylic acid polymers, etc.). Molecules can form hydrogels through physical cross-linking, electrostatic interaction, or chemical cross-linking, and hydrogel microneedles are prepared by template method.

Why Choose CD Formulation?

Advanced Materials: We use innovative biocompatible and biodegradable polymers, enhancing drug delivery efficiency and safety.
Precision Engineering: Our high-precision manufacturing ensures optimal microneedle length, density, and distribution for effective drug administration.
Tailored Solutions: Customizable solutions designed to meet specific research requirements, such as varying drug dosages or release rates.

Results: Transdermal drug delivery (TDD) is one of the key approaches for treating diseases, avoiding first-pass effects, reducing systemic adverse drug reactions, and improving patient compliance. Microneedling, iontophoresis, electroporation, laser ablation, and ultrasound facilitation are often used to improve the efficiency of TDD. Among them, microneedling is a relatively simple and efficient means of drug delivery. Microneedles usually consist of micron-sized needles (50–900 μm in length) in arrays that can successfully penetrate the stratum corneum and deliver drugs in a minimally invasive manner below the stratum corneum without touching the blood vessels and nerves in the dermis, improving patient compliance. Hydrogel-forming microneedles (HFMs) are safe and non-toxic, with no residual matrix material, high drug loading capacity, and controlled drug release, and they are suitable for long-term, multiple-drug delivery. This work reviewed the characteristics of the skin structure and TDD, introduced TDD strategies based on HFMs, and summarized the characteristics of HFM TDD systems and the evaluation methods of HFMs as well as the application of HFM drug delivery systems in disease treatment.
