Development of Coated Copper T

Abi Santhosh Aprem of HLL Lifecare Ltd. in India will attempt to eliminate the side effects associated with copper T intrauterine devices by coating the copper with biodegradable polymers. The polymers could prevent bulk shedding of copper ions that cause bleeding, cramping and pain, leading to increased acceptance of this highly effective contraceptive device. In this project's Phase I research, Aprem determined the optimal polymer film and coating technique and demonstrated that it was safe and effective in controlling copper ion release at the required daily levels. In Phase II, clinical trials will be conducted to assess the safety, efficacy and acceptance of the coated copper T intrauterine device.
