• Verwenden

  Levamisole hydrochloride is an anthelmintic. The activity of levamisole is about twice as high as that of abscisicidal, and the toxicity and side effects are lower. Levamisole can cause muscle paralysis of roundworms and then excrete them in the feces. It is mainly used as an anti-worm and anti-hookworm.

• Verwenden

  Biological response modifier with anthelmintic activity. Anthelmintic (nematodes); immunomodulator.

• Definition

  ChEBI: Levamisole hydrochloride is an organic molecular entity.

• synthetische

  Levamisole hydrochloride was prepared from racemic tetraimidazole by splitting, alkali analysis and acidification into salt.
  Dibenzoyl-D-tartaric acid is boiled in water for 40min, hydrolyzed and neutralized with sodium hydroxide solution to pH 7.5, and then added to racemic tetraimidazole. The levamisole is precipitated by generating salt with bisbenzoyl-tartaric acid. After separation, add sodium hydroxide solution to PH=9 and decompose levamisole. Then dissolved in dilute hydrochloric acid solution, after decolorization by activated carbon, the filtrate was concentrated nearly dry, and crystallized by adding acetone and cooling to 0℃. Filtered and dried to obtain levamisole hydrochloride.

• Therapeutic Function

  Antiinflammatory

• Biochem/physiol Actions

  Shows both immunostimulant and immunosuppressant effects, depending on several controllable factors. Very effective in treatment of ascariasis (hookworm infestation). Useful in chemotherapy of colorectal cancers, possibly due to its stimulation of IL-1 production and direct activation of macrophages.

• Pharmakologie

  Levamisole Hydrochloride is the hydrochloride salt of the synthetic imidazothiazole derivative levamisole with anthelminthic and immunomodulating activities. In immunosuppressed states, levamisole may restore immune function by: 1) stimulating antibody formation, 2) stimulating T-cell activation and proliferation, 3) potentiating monocyte and macrophage phagocytosis and chemotaxis and 4) increasing neutrophil mobility, adherence, and chemotaxis.

• Pharmakokinetik

  Levamisole is rapidly absorbed from all routes of administration, with peak blood levels occurring within an hour followed by rapid metabolism and depletion principally via urinary excretion, with an elimination half-life of approximately 4 h.

• Mode of action

  Levamisole is a cholinergic receptor agonist and elicits spastic muscle paralysis due to prolonged activation of the excitatory nicotinic acetylcholine receptors (nAChR) on nematode body wall muscle.

• Toxicity evaluation

  Symptoms of levamisole toxicity mimic organophosphate toxicity (salivation, lacrimation, urination and defecation, hyperesthesia, seizures and irritability). There is no antidote for levamisole toxicity.
  The World Health Organization reviewed hematological studies in animals and humans and derived acceptable daily intake for levamisole as 0.006 mg/kg body weight. This suggests a person can ingest 0.36 mg of levamisole/day over a lifetime without any appreciable risk.
