Customized Membrane Permeation Controlled Systems

CD Formulation is committed to providing one-stop integrated solutions for drug delivery system development, from research and evaluation, proposal development, process development, and product delivery, CD Formulation has established a comprehensive process service system.


In membrane permeation controlled systems, the drug reservoir is completely encapsulated in a shallow compartment made of a metal-plastic laminate that is impermeable to the drug and molded with a rate-controlled polymer membrane (e.g., ethylene vinyl acetate with defined drug permeability). The drug is released only through the microporous or nonporous rate control membrane. In the drug reservoir, the drug solids are either dispersed in a solid polymer matrix or suspended in a viscous liquid medium, forming a paste-like suspension. A layer of drug-compatible, hypoallergenic adhesion polymer can be applied to the outer surface of the polymer membrane (rate control membrane) to achieve close contact between the transdermal system and the skin surface.

Our Services

CD Formulation can customize polymeric membrane permeation control systems, where each component can find a corresponding product customization pathway in our company, or if not, feel free to contact our staff and we will develop a specific product solution for you. At the same time, our experienced drug delivery system development department can also provide polymer membrane modification products and modification process development services to help improve polymer membrane properties for drug delivery by changing the composition of the polymer, permeability coefficient and thickness of the rate-controlled membrane to adjust the release rate of this type of transdermal drug delivery system.
