The Active Form of Tryparsamide, TPB, in the Treatment of Human Trypanosomiasis

View More View Less


TPB represents the “active form”, i.e. the arsenoxide of tryparsamide in a stabilized and detoxified form, combining high trypanocidal activity towards the trypanosomes in blood and lymph and CSF, with the propensity to clear up readily the trypanosome meningo-encephalitis.

TPB is without effect on tryparsamide resistant trypanosomes.
