30g paste syringe.

Active Ingredients:

Each gram contains 4.0mg Abamectin, 50.0mg Praziquantel and 200.0mg Oxfendazole.


Abamectin stimulates the release of the neurotransmitter GABA in roundworms, which increases the membrane permeability of neurons to chloride ions. Normal neural transmission is thus inhibited causing paralysis and death of the parasite. Praziquantel affects the attachment of tapeworms to the host tissues by causing spastic paralysis. It also damages the tegument and as a result increases the permeability of the membrane to certain cations. The tapeworms are then destroyed in situ. Oxfendazole destroys Abamectin resistant Parascaris equorum by inhibiting tubulin synthesis in the parasite, which then causes death by starvation.
