概要
Both drugs can prolong the QT interval, and posaconazole may also increase artemether exposure. Together they raise the risk of torsades de pointes.
この相互作用をわかりやすく説明すると
Artemether and Posaconazole are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
