artemisinin
Artemisinin () and its semisynthetic derivatives are a group of drugs used in the treatment of malaria due to Plasmodium falciparum. It was discovered in 1972 by Tu Youyou, who shared the 2015 Nobel Prize in Physiology or Medicine for her discovery. Artemisinin-based combination therapies (ACTs) have become standard treatment worldwide for P. falciparum malaria as well as malaria due to other species of Plasmodium. Artemisinin can be extracted from the herb Artemisia annua (sweet wormwood), which is used in traditional Chinese medicine. Alternatively, it can be prepared by a semi-synthetic met

lumefantrine
Lumefantrine (or benflumetol) is an antimalarial drug. It is only used in combination with artemether. This combination is frequently the first-line medication for Plasmodium falciparum malaria. Lumefantrine has a much longer half-life compared to artemether (3-6 days vs. 2 hours), and is therefore thought to clear any residual parasites that remain after combination treatment.
artemether
Artemether is a medication used for the treatment of malaria. The injectable form is specifically used for severe malaria rather than quinine. In adults, it may not be as effective as artesunate. It is given by injection in a muscle. It is also available by mouth in combination with lumefantrine, known as artemether/lumefantrine.
dihydroartemisinin
Dihydroartemisinin (also known as dihydroqinghaosu, artenimol or DHA) is a drug used to treat malaria. Dihydroartemisinin is the active metabolite of all artemisinin compounds (artemisinin, artesunate, artemether, etc.) and is also available as a drug in itself. It is a semi-synthetic derivative of artemisinin and is widely used as an intermediate in the preparation of other artemisinin-derived antimalarial drugs. It is sold commercially in combination with piperaquine and has been shown to be equivalent to artemether/lumefantrine.
pyronaridine
Pyronaridine is an antimalarial drug. It was first made in 1970 and has been in clinical use in China since the 1980s.
piperaquine
Piperaquine is an antiparasitic drug used in combination with dihydroartemisinin to treat malaria. Piperaquine was developed under the Chinese National Malaria Elimination Programme in the 1960s and was adopted throughout China as a replacement for the structurally similar antimalarial drug chloroquine. Due to widespread parasite resistance to piperaquine, the drug fell out of use as a monotherapy, and is instead used as a partner drug for artemisinin combination therapy. Piperaquine kills parasites by disrupting the detoxification of host heme.
