CD Formulation boasts extensive project experience in the development of transdermal drug formulations, equipped with relevant transdermal and analytical instruments to offer professional and efficient services in nucleic acid drug development, modification, and analysis.
Transdermal Drug Delivery Systems (TDDS) represent a unique route of administration that employs skin as a conduit for drug absorption, allowing direct entry into the bloodstream for disease prevention or treatment. TDDS is recognized for its safety and good tolerance, combining the dosage accuracy and simplicity of oral formulations with the potential to deliver therapeutics non-metabolically to plasma associated with parenteral routes. Transdermal formulations include patches, ointments, plasters, paints, and aerosols.
Unique Advantages of Transdermal Nucleic Acid Formulation Development
Items | Descriptions |
---|---|
Reservoir-Type Transdermal Drug Formulation Development | This type of percutaneous delivery system involves drugs or transdermal absorption enhancers encapsulated in a controlled-release membrane or other release-controlling materials. The rate of drug release is regulated by the properties of the membrane or materials used. |
Matrix-Type Transdermal Drug Formulation Development | In this form of skin-based delivery system, the active substance is either dissolved or evenly distributed throughout a polymer framework, with its release rate being governed by the composition of this structure. |
CD Formulation can create transdermal penetration enhancers customized to meet client requirements. We select various types of enhancers based on specific applications and develop appropriate formulations.
The typical classifications of these enhancers are outlined below:
Perform both prolonged and accelerated stability evaluations in varying environmental conditions to ensure formulation components remain intact and avoid degradation throughout storage and use.
Precisely assess formulation attributes like pH, electrical conductivity, and viscosity to confirm its uniformity and dependability across different conditions.
Verify that the transdermal formulation remains microorganism-free during its production and storage phases, achieving sterility or minimal microbial presence as per regulatory standards.
In vitro evaluation focuses on determining content, release rate, transdermal permeability, and adhesion properties. In vivo evaluation involves assessing bioavailability and conducting studies on in vitro-in vivo correlation.
Quick-stick force refers to a TDDS (transdermal drug delivery system) system's ability to adhere to the skin with minimal pressure. Various methods include:
Cohesion relates to the shear strength of pressure-sensitive adhesives (PSA) and is measured by their ability to resist creep under shear stress, known as holding power. Adequate cohesion ensures that the TDDS system remains in place during use and leaves no residue upon removal.

Combining customer needs with the characteristics of nucleic acid drugs, we design appropriate types of transdermal delivery formulations (such as reservoir type or matrix type), determine suitable transdermal absorption enhancers, and develop preliminary formulation schemes.
We conduct initial preparation of transdermal delivery formulations, testing for drug content and absorption rate, and examine the formulation's stability and safety under various conditions.
Based on preliminary test results, we optimize the formulation and release system, conduct pilot scale-up tests to verify the feasibility and consistency of the formulation in mass production.
Conduct comprehensive in vitro evaluations, including release rate, permeability, and adhesion performance tests, and use in vivo evaluation methods to study bioavailability and consistency.
After passing all quality control tests, we perform process validation and prepare for mass production, ensuring the controllability and consistency of all quality indicators during the production process.
Our platform covers the preparation process of nucleic acid drugs, involving the selection of suitable materials and processes to ensure the stability and effectiveness of formulation development.
Our platform focuses on the application of analytical technology, using advanced tools and methods to evaluate the quality and performance of nucleic acid formulations, ensuring product reliability and consistency.
