  • Title: Determination of the antimalarial arteether and its deethylated metabolite dihydroartemisinin in plasma by high-performance liquid chromatography with reductive electrochemical detection.
    Author: Melendez V, Peggins JO, Brewer TG, Theoharides AD.
    Journal: J Pharm Sci; 1991 Feb; 80(2):132-8. PubMed ID: 2051315.
    Abstract:
    A rapid, sensitive, and specific reversed-phase HPLC method using reductive electrochemical detection has been developed for the determination of arteether and its O-dealkylated metabolite dihydroartemisinin (DQHS) in plasma. The internal standard assay was validated between 25 and 1000 ng/mL, with a coefficient of variation of greater than 10% for both intra- and interday accuracy and precision. An assay for determination of arteether only, using the n-propyl ether of DQHS as internal standard, was also developed and validated from 5-500 ng/mL. A new automated sample deoxygenation and injection system is used to greatly increase sample throughput. These methods have been used to study the pharmacokinetics of arteether after intravenous and intramuscular administration.
