Niclosamide Usage And Synthesis
Anti-parasitic disease drugNiclosamide belongs to the taeniafuge drugs of the anti-parasitic disease drugs , it is less toxic, it has a high efficacy on a variety of tapeworm, tapeworm mechanism is hampering tapeworm Krebs cycle, so that lactic acid is accumulated which can cause the death of the parasites, it is drug of choice in livestock and poultry, pet tapeworm prevention . Oral absorption from the gastrointestinal tract is very little, so it can maintain a high concentration in the intestine, it has a strong insecticidal action against the pork tapeworm, and beef tapeworm short Hymenolepis . Low concentrations of the drug can promote parasite uptake, while high concentrations of the drug can inhibit mitochondrial oxidative phosphorylation of the parasite, and hinder the absorption of glucose uptake,and result in tapeworm head and proximal segments death, and elimination with the feces from the intestinal wall . Mainly it is used for tapeworm infection, but it is also used as molluscidal drugs which can kill snails and snail eggs, cercariae and miracidia. It has high rate of snail eradication , slow effect, long residual effect, it is used for the prevention of schistosomiasis, the temperature above 20 ℃ is better. In addition ,the product is friendly to human, animal and plant,it is very toxic to fish, so use in the fish ponds is forbidden .
1960 Germany reported a synthetic chemical repellent-Niclosamide whose code is Bayer 73 the drug is pale yellow powder, odorless, tasteless. Insoluble in water, slightly soluble in alcohol, ether and chloroform,it can be dissolved in hot ethanol, cyclohexanone and an aqueous solution of sodium hydroxide, the compound is stable.Niclosamide have a better effect on beef tapeworm, pork tapeworm, H. nana and Diphyllobothrium tapeworm, . Few drug absorption occurs in the gastrointestinal tract, when the drug is exposed with parasites, parasites die soon. Therefore, when the medication, the tablets should be chewed, so drugs can make full contact with tapeworm parasites, and a lot of water immediately should be avoided, in order to maintain a high concentration of upper small intestine where lies the parasitic tapeworm . The drug can kill adults tapeworm rather than eggs tapeworm , in order to prevent vomiting, which make the eggs reflux into stomach , and cause the risk of cysticercosis occurring, anti-emetics should be added before the medication . 2 hours after administration, it should be served magnesium sulfate for catharsis, to get rid of the parasite and the cleaved head section and debris. The drug has low toxicity, rat oral LD50 of 5g/kg. This product can also be made with amino ethanol to serve as soluble snail drugs under the trade name niclosamide (bayluscide),in the country, Niclosamide and alkali waste pulp can be made for soluble pastes, called schistosomiasis-67. These can be used to kill the snail which is the intermediate host of Schistosoma japonicum. Regardless of spraying or soaking ,the amount of snail, is 1g/m2. Pulp paste for live use (ie schistosomiasis-67), accounts for 50% of Niclosamide . Oral adverse reactions are mild, except for gastrointestinal reactions, occasional dizziness, chest tightness, fever and other discomfort occur. There is no liver, kidney, blood system injury.

Pharmacology and mechanism of actionNiclosamide is a chlorinated salicylanilide derivative which was introduced during the 1960s. It is an anthelminthic drug highly effective against beef tapeworm (Taenia (T.) saginata), pork tapeworm (T. solium), fish tapeworm (Diphyllobothrium (D.) latum) and dwarf tapeworm (Hymenolepis (H.) nana). The mechanism of action of the drug is not clearly known. It interferes with the energy metabolism of helminths, possibly by inhibiting adenosine triphosphate (ATP) production. It also inhibits glucose uptake by the parasites [1].
IndicationsInfections caused by T. saginata, D. latum, and H. nana. The drug is also effective against T. solium, but the danger of cysticercosis makes praziquantel preferable.
Side effectsNiclosamide is generally free of undesirable effects. Minor gastrointestinal complaints such as nausea, vomiting, abdominal pain, diarrhoea, light-headedness and pruritus are rarely encountered.
Contraindications and precautionsDrugs which cause vomiting should not be taken simultaneously with niclosamide to avoid retrograde infection by eggs. Use of niclosamide against T. solium infection may expose the patient to the risk of cysticercosis. In such a case, special precautions are needed (see Dosage below).
