Mectizan® procurement and delivery for onchocerciasis mass drug administration programmes

The discovery of Mectizan has engendered a safe onchocerciasis chemoprevention tool. To make the drug available promptly to people at risk of onchocerciasis, a procurement and delivery mechanism has been put in place around the Mectizan Donation Program, which oversees the Merck donation of Mectizan. The number of yearly approved treatment doses has increased rapidly since 1988 from 255,000 to more than 80 million in 2007 and 2008. Cumulatively, from 1987 to 2008 more than 697 million treatment doses have been approved corresponding to 1.5 billion Mectizan tablets shipped. Although the current demand for treatment is met, the ultimate goal is to cover all people at risk. A comprehensive drug policy from recipient countries is still needed to back up the current efficient procurement and delivery mechanism in order to attain the ultimate to goal, and is equally important for scaling up mass drug administration as part of national neglected tropical disease control/elimination strategies.
