Artesunate suppositories work with artemisinin suppositories in severe malaria was conducted in Viet Nam in the early 1990s, and clinical trials of rectal artesunate followed by mefloquine treatment in moderately severe malaria were conducted in the mid-1990s in Thailand. A major placebo-controlled clinical trial published in 2009 found that "if patients with severe malaria cannot be treated orally and access to injections will take several hours, a single inexpensive artesunate [rectal] suppository at the time of referral substantially reduces the risk of death or permanent disability."
