Current chemotherapy of human African trypanosomiasis

Abstract

Human African trypanosomiasis is a fatal disease caused by Trypanosoma brucei gambiense and Trypanosoma brucei rhodesiense that has re-emerged in recent years. However, very little progress has been made in the development of new drugs against this disease. Most drugs still in use were developed one or more decades ago, and are generally toxic and of limited effectiveness. The most recently introduced compound, eflornithine, is only useful against sleeping sickness caused by T. b. gambiense, and is prohibitively expensive for the African developing countries. We present here an overview of today's approved and clinically used drugs against this disease.
