Isometamidium chloride is a triazene trypanocidal agent used in veterinary medicine.

It consists of a single ethidium bromide like subunit linked to a fragment of the diminazene molecule.[citation needed]

Resistance

The Gibe River Valley in southwest Ethiopia showed universal resistance between July 1989 and February 1993. This likely indicates a permanent loss of function in this area against the tested target, T. congolense isolated from Boran cattle.
