Effect of alpha,beta-arteether against primary amoebic meningoencephalitis in Swiss mice.

ABSTRACT

Artemisinin and its derivative alpha, beta-arteether have been evaluated for activity against experimental primary amoebic meningoencephalitis. In vivo experiments have shown that amphotericin B at dose of 2.5 mg/kg for 5 days produced 100% protection. Artemisinin and alpha, beta-arteether, even when tested at a high doses (60-120 mg/kg x 5 days and 90-180 mg/x 5 days) respectively, were not curative and showed only slight protection as indicated by extension of mean survival time.
