Analysis of the antimalarial, mefloquine, in blood and plasma using high-performance liquid chromatography

Journal of Chromatography
I M KapetanovicM H Heiffer


An analytical method is described for the quantitation of mefloquine, a new antimalarial agent, in plasma and blood. A structurally similar quinolinemethanol compound, WR 184,806, is used as the internal standard. The method employs a three-step extraction procedure followed by reversed-phase high-performance liquid chromatography, and octanesulfonate is used as an ion-pairing reagent. Detection is achieved at 222 nm. The entire procedure is relatively simple and requires only 1 ml of sample. Good accuracy and precision are obtained over the wide concentration range tested.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration
