Discussion Dosing Al. Following the WHO guidelines for the treatment of malaria (WHO, 2006, pages 23–24) the recommended dose for artemether/lumefantrine tablets (Coartem®) when used for children between 5 and 14 kg is 1 tablet at time 0 h and 1 tablet at time 8 h followed by two tablets a day for two days (24, 36, 48 and 60 h). Calculated as mg artemether per kg body weight (bw), this means that for a child of 5 kg a dose of 8 mg artemether/kg per day spread over two doses is given. Evidence that this high dose of more than 4 mg/kg bw of artemether is needed for small babies (± 5 kg) is scanty or non existent. Moreover, this "overdosing" situation is in contrast with the adult dose of 8 pills a day divided over two intakes. This means that an adult of 50 kg takes a dose of 3.2 mg/kg of artemether and an adult of 75 kg takes one of 2.1 mg/kg per day. There is no dose finding study published that we could find to justify this variation in dosing.
