Diethylcarbamazine is an orally active microfilaricidal agent used originally in onchocerciasis and lymphatic filiariasis. Diethylcarbamazine reduces eosinophil trafficking to the lung tissue and exerts anti-allergic effects. Diethylcarbamazine reduces serum levels of leptin, TNF-alpha, IL-6, MCP-1, glucose, insulin, and triglycerides, and ameliorates insulin resistance without altering body, liver, or adipose tissue weights. Diethylcarbamazine enhances reactive oxygen intermediate expression by polymorphonuclear neutrophils, increases lymphocyte proliferation, and inhibits actinomycetoma lesion development. Diethylcarbamazine can be used for the researches of bronchial asthma, insulin resistance and infection[1][2][3].
