Tryparsamide is an arsenic compound with activity against Spirochaetes bacteria. Tryparsamide is used in the treatment of syphilis and African sleeping sickness. For decades Tryparsamide remained the standard treatment for trypanosomiasis. Tryparsamide has two remarkable properties: first, it increases the resistance of the individual by improving his general physical status; and, second, the high penetrability for nervous tissue which it possesses may increase the potential spirocheticidal action of the drug.
