Vetodium-1gm

Indications

• Trypanosomiasis in cattle
• Prevention of African sleeping sickness in livestock

Dosage

Children: Refer to the BNF for Children for specific dosing recommendations.

Adults: Refer to the BNF for specific dosing guidelines as it varies based on the condition and species treated.

Mechanism of action

Isometamidium acts by intercalating into the DNA of the parasite, disrupting replication and transcription processes. This impairs the synthesis of essential proteins and nucleic acids, leading to the death of the trypanosome.

Pharmacodynamics

The pharmacodynamics of isometamidium involve its selective toxicity to trypanosomes, which are more susceptible to its effects compared to mammalian cells. The drug's high affinity for the DNA of the parasites ensures that it efficiently inhibits their growth and replication. The efficacy of isometamidium is influenced by factors such as the strain of the trypanosome and the pharmacokinetic profile of the drug.

Pharmacokinetics

Isometamidium is administered parenterally, and it exhibits a relatively long half-life, allowing for sustained therapeutic levels in the bloodstream. The drug is distributed widely in body tissues, including the liver and kidney, where it can exert its effects against the parasites. It is metabolized in the liver and excreted primarily through urine, although specific metabolic pathways remain to be fully elucidated.

Pregnancy

Isometamidium should only be used if the potential benefit justifies the potential risk to the fetus. Consult relevant guidelines for use during pregnancy.

Breast-feeding

The effects on breastfeeding infants are unknown. Caution is advised when administering to nursing mothers.

Storage

Store in a cool, dry place away from light. Keep out of reach of children.
