Pharmacia-Leiras has launched Mirena, a hormone-releasing intra-uterine device, in the UK. The contraceptive action of the T-shaped device relies on local delivery of levonorgestrel from a cylindrical reservoir around the stem of the implant. The hormone is released at a rate of 20 ug/day and plasma concentrations are lower than those experienced with oral contraceptives. The device is designed to last for five years. Product launches in Belgium and Switzerland are planned this year.
