How It Works

This medicine works by passive immunisation. It contains purified immunoglobulin fragments (mainly Fab or F(ab')2) raised in horses against the venom of Naja naja and Bungarus caeruleus. These antibodies bind to venom toxins in the bloodstream and neutralise them, preventing them from reaching their target tissues such as neuromuscular junctions and cardiac muscle. The immune complexes formed are then cleared by the reticuloendothelial system.

Mechanism Steps

1
Binding to venom toxins: Antibody fragments in this medicine specifically bind to venom proteins from cobra and krait.
2
Neutralisation: The binding blocks the active sites of the toxins, preventing them from interacting with acetylcholine receptors or other targets.
3
Clearance: The antibody-venom complexes are removed from circulation by the liver and spleen.
