Mechanism of Action
Diethylcarbamazine is an inhibitor of arachidonic acid metabolism in filaria. This makes the filaria more susceptible to immune attack.
Diethylcarbamazine is indicated for treatment of individual patients with certain filarial diseases. These diseases include: lymphatic filariasis caused by infection with Wuchereria bancrofti, Brugia malayi, or Brugia timori; tropical pulmonary eosinophilia, and loiasis.
In cases of onchocerciasis, another common filarial parasite, the drug is not used. This is because the itching associated with the dead subcutaneous parasites causes intense and unbearable itching.
Diethylcarbamazine continues to be the mainstay for treatment of patients with lymphatic filariasis and loiasis. Diethylcarbamazine is also used in the prevention of dogheartworm Dirofilaria immitis.
