WORMOL (Mebendazole)

Advertisement

Mebendazole is a benzimidazole carbamate derivative with broad spectrum anthelmintic activity. It is particularly active against gastro-intestinal nematodes (roundworms) and some cestodes (tapeworms). Activity against some larval stage and ova has also been demonstrated.

It appears to act by irreversible inhibition of glucose uptake in susceptible worms resulting in depletion of their energy stores, glycogen and adenosine triphosphate, resulting in their slow death.

Pharmacokinetics

Mebendazole is poorly absorbed from the gastro-intestinal tract and undergoes extensive first-pass elimination, being metabolized in the liver, eliminated in the bile as unchanged drug and metabolites and excreted in the faeces.

Only about 2% of a dose is excreted unchanged or as metabolites in the urine.
