Is levamisole harmful to humans?
Although not available for human use, levamisole remains widely used in veterinary medicine for treating worms in livestock and domesticated animals. The drug can cause agranulocytosis, as well as vasculitis, which prompted the FDA ban on human use.
What is the mechanism of action of levamisole?
The mechanism of action of levamisole as an antiparasitic agent appears to be tied to its agnositic activity towards the L-subtype nicotinic acetylcholine receptors in nematode muscles. This agonistic action reduces the capacity of the males to control their reproductive muscles and limits their ability to copulate.
What is levamisole induced vasculitis?
Levamisole-induced vasculitis is a cutaneous vasculitis that has been reported with smoked crack cocaine and inhaled cocaine powder. It has a greater frequency in women (male to female ratio 1:3), with a mean age of presentation of 44 years.
Is levamisole a stimulant?
The neuropharmacological profile of LVM is also suggestive of an agent with modest reinforcing and stimulant effects that could enhance cocaine’s addictive effects.
Why is levamisole in Coke?
One explanation for the addition of levamisole to cocaine is that it increases the amount of product and enhances profits.
Is levamisole an immunosuppressant?
Levamisole can act either as an immunostimulant agent or an immunosuppressive agent. These apparently paradoxical effects depend upon the dose administered, the timing of its administration, the experimental assay used to measure effects, and the host genetic background.
What does levamisole look like?
Levamisole is an imidazothiazole chemical most frequently used as an antihelminthic agent in cattle. Over the last decade, levamisole has been increasingly encountered as an additive in both powder and crack cocaine. A white powder with a “fish scale” appearance, the chemical is physically similar to powder cocaine.
How long does levamisole take to work?
Levamisole is readily absorbed from the gastrointestinal tract and metabolized in the liver. Its time to peak plasma concentration is 1.5–2 hours.
Is levamisole the same as ivermectin?
In addition, both of the 2 drugs were found to be more efficacious for migrating larvae than for encapsulated larvae. In the mass, ivermectin was superior to levamisole with regard to decreasing both free and encapsulated larvae.
Why is levamisole used?
Levamisole is an immunomodulatory agent that was used to treat various cancers before being withdrawn from the United States market in 2000 because of adverse effects. Levamisole is currently approved as an antihelminthic agent in veterinary medicine, but is also being used illicitly as a cocaine adulterant.
What is levamisole adulterated cocaine vasculopathy?
Levamisole-adulterated cocaine vasculopathy is exclusively reported in cocaine users, more often with chronic use and in those smoking and snorting contaminated cocaine [6,7]. It can also occur when cocaine is injected. The average age of patients at presentation is 44 years old [1].
Who is at risk for levamisole-induced vasculitis?
Any person who uses cocaine is at risk for developing levamisole-induced vasculitis. Since its presence in cocaine was first documented in the United States in 2003, and soon thereafter in Europe and Canada, the percent of cocaine cut with levamisole has steadily increased.
How do you test for levamisole in urine?
Urine levamisole is detected by gas chromatography mass spectrometry and must be performed within 48 hours. It is only detected in 13% of patients with suspected levamisole-adulterated cocaine vasculopathy [6,12]. Urinalysis may reveal proteinuria, haematuria and cellular casts [2,12].
Is levamisole legal in the US?
Levamisole is an anthelmintic medication currently only licensed in the United States and Canada for use in veterinary medicine, due to reports of adverse events including agranulocytosis (severely decreased white blood cell count), facial retiform purpura and serological abnormalities in humans.
