A single-layer drug-in-adhesive transdermal patch integrates the drug and adhesive into one layer, providing an efficient, user-friendly method to deliver drugs systemically through the skin. With over two decades of formulation expertise, CD Formulation specializes in single-layer drug-in-adhesive transdermal patch development, ensuring optimized drug delivery and performance.

Typically, a transdermal patch can be composed of single or multiple layers of solid or semi-solid structures. The configuration of these layers determines the diffusion of the active ingredient through the skin. A single-layer drug-in-adhesive transdermal patch refers to a system where the adhesive layer itself contains the drug. This layer ensures that the patch adheres to the skin while facilitating the controlled release of the drug into the bloodstream through the epidermis and dermis. The backing layer protects the adhesive side prior to application, ensuring the drug is securely contained.
These patches offer controlled drug release, reducing potential side effects and enhancing patient compliance. Their ability to bypass the liver reduces systemic exposure and improves safety.

We offer a full range of transdermal patch development services, ensuring precision and effectiveness in each step:
We can modify the drug as needed, such as nano, to improve its solubility and permeability, thereby enhancing the efficacy of the drug and reducing side effects.
Design the adhesive matrix to control the release of the drug through diffusion or dissolution mechanisms.
Design the adhesive layer to provide sufficient adhesion to the skin while allowing controlled release of the drug.
Selection of suitable polymers for the adhesive matrix that provides good adhesion to the skin and controls the release of the drug at the desired rate.

Results: In a single-layer drug-in-adhesive system, the adhesive layer not only functions as the sticky element but also houses the medication. This adhesive layer facilitates drug release while affixing the multiple layers of the system onto the skin. The adhesive layer is surrounded by a temporary liner and backing for the patch. An instance of this type of transdermal product is Daytrana®, a patch containing methylphenidate.
The single-layer drug-in-adhesive patch is absorbed directly through the skin surface, reducing the side effects of drugs on the liver and other organs, and improving the safety of use. During the product development process, we conducted comprehensive toxicological studies and safety assessments to ensure that the single-layer transdermal patch was safe. At the same time, the effectiveness and safety of the product were verified through clinical trials.
