Used primarily as an antiprotozoal agent in veterinary medicine, especially for the treatment of trypanosomiasis in cattle and other livestock. It is effective against a range of protozoan parasites including Trypanosoma species. It acts by inhibiting the replication of parasite DNA, preventing multiplication and leading to parasite death. Commonly administered by injection, it helps control parasitic infections that affect animal productivity and health in tropical and subtropical regions. Also shows activity against some Babesia and Anaplasma species, making it useful in treating tick-borne diseases in animals. While effective, caution is advised due to potential side effects such as injection site irritation or neurotoxicity at high doses. Its use in humans is limited due to toxicity concerns.
