Indications & Uses

Remazin treats filariasis (including lymphatic filariasis), pulmonary eosinophilia, loiasis, and toxocariasis.

Pharmacology

Mechanism of action: diethylcarbamazine appears to work by sensitising the microfilariae to phagocytosis. One study found that its activity against Brugia malayi microfilariae depends on inducible nitric-oxide synthase and the cyclooxygenase pathway. This confirmed that the arachidonic acid metabolic pathway plays an important part in the drug's mechanism of action in vivo, and showed that, besides acting on the 5-lipoxygenase pathway, it also targets the cyclooxygenase pathway and COX-1.
