Levamisole Usage And SynthesisPharmacology and mechanism of actionLevamisole is the L-isomer of tetramisole and is more active than the racemic mixture. It was introduced in 1966 as a veterinary drug and a little later as a human anthelminthic drug against ascariasis. The drug has also shown to be effective against hookworms (Ancylostoma duodenale and Necator americanus), but results of reported studies are inconsistent ^[1]. The mechanism of action of levamisole in helminthiasis is through its stimulation of autonomic ganglia (nicotinic receptors) of the worms. On exposure to the drug, immature and adult worms show spastic contraction followed by tonic paralysis. This mechanism seems to be common to other anthelminthics such as pyrantel and bephenium hydroxynaphthoate ^[2]. In higher doses, levamisole acts as an immunostimulant. It restores depressed cell-mediated immune mechanisms in peripheral T-lymphocytes, but may have marginal effects in immunologically competent individuals ^[3]. The clinical implication of this effect in the treatment of helminthiasis is unknown.IndicationsMonoinfections with Ascaris lumbricoides. In polyinfections, mebendazole is the drug of choice.Side effectsDuring the treatment of nematode infections the drug produces minor side effects including nausea, vomiting, abdominal pain and headache^{[4, 5]}. During prolonged treatment as an immunomodulator in rheumatic arthritis and in cancer patients, serious side effects such as blood disorders (agranulocytosis, neutropenia and thrombocytopenia), kidney damage, influenza-like reactions, vasculitis, photosensitivity and allergy to the drug have been reported ^{[6, 7]}.Contraindications and precautionsThe drug should be avoided in patients allergic to the drug. Administration of levamisole may provoke a reaction similar to that seen after intake of alcohol together with disulfiram. During long-term treatment, patients with kidney damage or with blood disorders may experience exacerbation of their diseases.InteractionsLevamisole has been reported to displace the protein binding of rifampicin in vitro^[8]. The clinical significance of this is as yet unknown.PreparationsAvailable as levamisole hydrochloride: 118 mg is equivalent to 100 mg base.

Synonyms of this drug are decaris, tetramizole, and others.
Levimasole is also a drug of choice for ascardiasis. Numerous investigations show that a single dose of levamisole heals from 90 to 100% of patients with ascardiasis, in particular those infected with A. duodenale. It is less effective against ancylostomiasis and strongyloidiasis. However, it is not effective against N. americanus. It seems likely that it has a gangliostimulating effect on parasite tissues in both the parasympathetic and sympathetic regions. Moreover, it is presumed that this drug has an immunomodulatory effect on the host organism. Synonyms of this drug are decaris, solacil, ergamisol, tramisol, immunol, and others.
