Transdermal formulation, also known as the transdermal drug delivery system (TDDS), involves the absorption of drugs through the skin into systemic circulation to achieve effective blood concentrations for local or systemic therapeutic effects. It is the third-largest drug delivery route after oral administration and injection. CD Formulation, a leader in transdermal drug delivery technology, is committed to supporting the research and development of innovative transdermal formulations.

The transdermal drug delivery process consists of three main steps: the release of active ingredients, penetration through the skin or mucosa, and absorption into systemic circulation. First, the active ingredient is released from the formulation and diffuses to the skin's surface. Then, it penetrates the epidermis to reach the dermis and subcutaneous tissues. Finally, it is absorbed into the bloodstream or lymphatic vessels, circulating throughout the body to exert therapeutic effects.
Compared to injections and oral formulations, transdermal formulations offer the following benefits:
Fig.2 Advantages of Transdermal Formulations (CD Formulation)
We conduct thorough evaluations of the physicochemical properties, solubility, and pharmacokinetics of drug molecules to identify candidates suitable for transdermal delivery.
We specialize in matrix selection, drug release regulation, and permeability enhancer optimization, ensuring that the prepared formulations achieve stable and effective drug delivery.
Using advanced in vitro skin models, we evaluate the formulation's absorption, release rate, and distribution across the skin.
We analyze the drug's release rate and mechanism in different transdermal formulations to ensure controlled and sustained delivery.

Results: This article will initially discuss each transdermal enhancement method used in first-generation products. These methods include drug/vehicle interactions, vesicles and particles, stratum corneum modification, energy-driven methods, and stratum corneum bypassing techniques. Through suitable design and implementation of active stratum corneum bypassing methods, notably microneedle technology, transdermal delivery systems have been shown to deliver both low and high-molecular-weight drugs. Microneedle technology platforms have proven themselves to be more versatile than other transdermal systems with opportunities for intradermal delivery of drugs/biotherapeutics and therapeutic drug monitoring. These have shown that microneedles have been a prospective strategy for improving transdermal delivery systems.
Transdermal drug delivery systems are safe and controllable, and combined with their advantages and characteristics, they have become a research hotspot for many scientific researchers in the pharmaceutical industry.
