Cu/LDPE Composite IUD | The Contraceptive Pipeline Database

Product Overview

Alternative Name: Nanocomposite Copper (Cu) IUD

Description: A blend of copper and low-density polyethylene (LDPE) nanocomposite material in an IUD shape. The new materials are designed to control the release rate of copper ions, without decreasing the efficacy of the IUD, but reducing the clinical side effects.

Updated date: May 30, 2018

Vertical Tabs

Product Details

Inactive material: polyethylene

Duration: 5 years

Status

Began discovery in: 2003

Status Details:
In 2013, the Cu/LDPE Composite IUD was registered by the Chinese FDA.

Programmatic Considerations

Considerations:
Nanotechnology prevents burst release of copper ions, which should result in fewer side effects and premature removals.

After years of research on copper ion release in simulated uterine environments, animal experiments and clinical trials, the result showed that the side effect rate with the new composite product was much lower than a standard copper IUD.

Sells for approximately US $300.
