Levamisole Wikipedia. Levamisole, sold under the trade name Ergamisol among others, is a medication used to treat parasitic worm infections. Specifically it is used for ascariasis and hookworm infections. It is taken by mouth. Side effects may include abdominal pain, vomiting, headache, and dizziness. Use is not recommended during breastfeeding or the third trimester of pregnancy. Serious side effects may include an increased risk of infection. It belongs to the antihelmintic class of medications. Levamisole was discovered in 1. It is on the World Health Organizations List of Essential Medicines, the most effective and safe medicines needed in a health system. The wholesale cost in the developing world is about 0.

It is not commercially available in the United States. Levamisole is also used as a dewormer for livestock. Medical useseditLevamisole was originally used as an anthelmintic to treat worm infestations in both humans and animals. Levamisole works as a nicotinic acetylcholine receptoragonist that causes continued stimulation of the parasitic worm muscles, leading to paralysis. In countries that still permit the use of levamisole, the recommended dose for anthelmintic therapy is a single dose, with a repeated dose 7 days later if needed for a severe hookworm infection. Most current commercial preparations are intended for veterinary use as a dewormer in cattle, pigs, and sheep. However, levamisole has also recently gained prominence among aquarists as an effective treatment for Camallanusroundworm infestations in freshwatertropical fish. After being pulled from the market in the U. S. and Canada in 1. Evidence from clinical trials support its addition to fluorouracil therapy to benefit patients with colon cancer. In some of the leukemic cell line studies, both levamisole and tetramisole showed similar effect. Levamisole has been used to treat a variety of dermatologic conditions, including skin infections, leprosy, warts, lichen planus, and aphthous ulcers. An interesting adverse side effect these reviewers reported in passing was neurologic excitement.

Later papers, from the Janssen group and others, indicate levamisole and its enantiomer, dexamisole, have some mood elevating or antidepressant properties, although this was never a marketed use of the drug. Adverse effectseditOne of the more serious side effects of levamisole is agranulocytosis, or the depletion of the white blood cells. In particular, neutrophils appear to be affected the most. This occurs in 0. There have also been reports of levamisole induced necrosis syndrome in which erythematous painful papules can appear almost anywhere on skin. It has been used as an adulterant in cocaine resulting in serious side effects. MetabolismeditLevamisole is readily absorbed from the gastrointestinal tract and metabolized in the liver. Its time to peak plasma concentration is 1. The plasma elimination half life is fairly quick at 34 hours which can contribute to not detecting Levamisole intoxication. The metabolite half life is 1. Levamisoles excretion is primarily through the kidneys, with about 7. Only about 5 is excreted as unchanged levamisole. Drug testing of racehorse urine has led to the revelation that among levamisole equine metabolites are both pemoline and aminorex, stimulants that are forbidden by racing authorities. Further testing confirmed aminorex in human and canine urine, meaning that both humans and dogs also metabolize levamisole into aminorex. The stimulant properties of aminorex contribute to the use of levamisole as a cocaine adulterant, potentiating the reinforcing effects of cocaine. Detection in body fluidseditLevamisole may be quantified in blood, plasma, or urine as a diagnostic tool in clinical poisoning situations or to aid in the medicolegal investigation of suspicious deaths involving adulterated street drugs. About 3 of an oral dose is eliminated unchanged in the 2. A post mortem blood levamisole concentration of 2. L was present in a woman who died of a cocaine overdose. Illicit useeditLevamisole has increasingly been used as a cutting agent in cocaine sold around the globe with the highest incidence being in the USA. In 2. 00. 82. 00. Drug Enforcement Administration DEA. By April 2. 01. 1, the DEA reported the adulterant was found in 8. Levamisole adds bulk and weight to powdered cocaine whereas other adulterants produce smaller rocks of cocaine and makes the drug appear purer. In a series of investigative articles for The Stranger, Brendan Kiley details other rationales for levamisoles rise as an adulterant possible stimulant effects, a similar appearance to cocaine, and an ability to pass street purity tests. Levamisole suppresses the production of white blood cells, resulting in neutropenia and agranulocytosis. With the increasing use of levamisole as an adulterant, a number of these complications have been reported among cocaine users. Levamisole has also been linked to a risk of vasculitis,3. Levamisole tainted cocaine was linked to several high profile deaths. Toxicology reports showed levamisole, along with cocaine, was present in DJ AMs body at the time of his death. Andrew Koppel, son of newsman Ted Koppel, was also found with levamisole in his body after his death was ruled a drug overdose. In 2. 01. 4 it was suspected to be involved in the death of a Sydney teenager. In response to the dangers, The Stranger, Peoples Harm Reduction Alliance and Dance. Safe began producing tests to identify levamisoles presence in cocaine. The kits include a survey postcard, and one revealed its presence in a 14 kg block of cocaine, indicating both users and dealers were using the kits. ChemistryeditThe original synthesis at Janssen Pharmaceutica resulted in the preparation of a racemic mixture of two enantiomers, whose hydrochloride salt was reported to have a melting point of 2. C the free base of the racemate has a melting point of 8. C. The racemic mixture is referred to as tetramisole levamisole refers only to the levorotatory enantiomer of tetramisole. ToxicityeditThe LD5. Laboratory useeditLevamisole reversibly and noncompetitively inhibits most isoforms of alkaline phosphatase e. It is thus used as an inhibitor along with substrate to reduce background alkaline phosphatase activity in biomedical assays involving detection signal amplification by intestinal alkaline phosphatase, for example in in situ hybridization or Western blot protocols. It is used to immobilize the nematode C. In a C. elegans behavioral assay, analyzing the time course of paralysis provides information about the neuromuscular junction. Levamisole acts as an acetylcholine receptor agonist, which leads to muscle contraction. Continuing activation leads to paralysis. The time course of paralysis provides information about the acetylcholine receptors on the muscle. For example, mutants with fewer acetylcholine receptors may paralyze slower than wild type. ResearcheditIt has also been studied as a method to stimulate the immune system as part of the treatment of cancer. ReferenceseditKeiser, J Utzinger, J 2. April 2. 00. 8.
