Adhesive Patches

Platform technology that supports TTS

An adhesive patch is a transdermal preparation placed on the skin to deliver compounds by absorption into the skin. Adhesive patches are a popular method of drug delivery because they have fewer adverse effects on the digestive system, cause less pain, and are more patient-friendly than oral administration or injections.
During adhesive patch development, advanced technologies are needed to create products that meet multiple requirements including fewer adverse skin reactions, sustained adhesiveness, and efficient absorption of active compounds.
With years of experience researching transdermal therapeutic systems (TTS), CosMED Pharmaceutical has established “medical adhesive technology” and “gelation technology” as essential technologies in adhesive patch development. CosMED Pharmaceutical is committed to developing optimized products.

Transdermal preparations, such as poultice-type patches and tape-type patches, are created on a platform of “medical adhesive technology” that combines adhesive technology and technology that ensures active compounds penetrate the skin.
Because adhesive patches may remain in contact with the skin for long periods of time, advanced specifications and designs are needed that meet a variety of requirements, including few adverse skin reactions, sustained adhesion without peeling, and resilience against external factors such as patient activity and weather. With extensive experience in the research and development of transdermal drug delivery systems, CosMED Pharmaceutical has acquired the technology and expertise needed to design optimal pharmaceutical preparations.

Gelation technology is an essential element in creating skin-friendly transdermal therapeutic systems that attach to the skin with an appropriate level of adhesion without causing adverse skin reactions while also being user-friendly. CosMED Pharmaceutical’s gelation technology softens and gelates macromolecular polymers with active compound components, and uses the resulting gel preparation as the base material for adhesive patches. This approach has been used to develop a wide range of products in not only the medical and pharmaceutical domains, but also the health and beauty domains, with the functional characteristics of these products receiving widespread recognition.

Friendly medical care, one patch at a time

In aging societies, there is a growing demand for drug delivery via adhesive patches, as drugs can be administered more conveniently to elderly patients who have difficulty swallowing, and compliance is easier to verify for caregivers. Self-medication is also considered an important factor in increasing healthy lifespans, and adhesive patches are garnering interest in this area as they offer a simple means of providing nutritional support via the skin. Advances are being made in techniques for the transdermal absorption of large-molecule drugs including peptides, nucleic acids, and proteins, and the emergence of adhesive patches that can offer this functionality is expected.
As an expert in the field with advanced technologies and extensive expertise in adhesive patches, CosMED Pharmaceutical is working hard to create innovative adhesive patch solutions.
