Mebendazole Winston
Mebendazole Winston Uses, Dosage, Side Effects, Food Interaction and all others data.
Mebendazole Winston is a synthetic derivative of benzimidazole with a potent anthelmintic activity against the most common nematodes and some cestodes. It is highly effective against ascariasis, enterobiasis, trichuriasis and hookworm infections. It is equally effective in single or in mixed infections. The effect of the drug is due to its ability to inhibit glucose uptake irreversibly but it does not affect blood glucose concentration in the host, even in high doses. Mebendazole Winston does not necessitate any dosage calculation since the same dosage is used for children and adults. It can be taken at any time and no special procedures such as purging, use of laxatives and/or dietary changes are required. Parasite immobilization and death occur slowly and clearance from the gastro-intestinal tract may not be completed up to 3 days after administration.
Mebendazole Winston is a (synthetic) broad-spectrum anthelmintic. The principal mode of action for Mebendazole Winston is by its inhibitory effect on tubulin polymerization which results in the loss of cytoplasmic microtubules.

Uses
Mebendazole Winston is used for the treatment of pinworm (Enterobius vermicularis), round worm (Ascaris lumbricoides), hookworm (Ancylostoma duodenale and Necator americanus), whip worm (Trichuris trichiura), tape worm (Taenia solium and taenia saginata) and threadworm (Strongyloides stercoralis) in single or mixed infections
Mebendazole Winston is also used to associated treatment for these conditions: Ancylostoma caninum infection, Ancylostoma duodenale infection, Ascaris lumbricoides infection, Capillariasis, Enterobius vermicularis infection, Filariasis, Giardiasis, Necatoriasis due to necator americanus, Strongyloides Stercoralis Infection, Taenia solium infection, Toxocariasis, Whipworm infection
How Mebendazole Winston works
Mebendazole Winston causes degenerative alterations in the tegument and intestinal cells of the worm by binding to the colchicine-sensitive site of tubulin, thus inhibiting its polymerization or assembly into microtubules. The loss of the cytoplasmic microtubules leads to impaired uptake of glucose by the larval and adult stages of the susceptible parasites, and depletes their glycogen stores. Degenerative changes in the endoplasmic reticulum, the mitochondria of the germinal layer, and the subsequent release of lysosomes result in decreased production of adenosine triphosphate (ATP), which is the energy required for the survival of the helminth. Due to diminished energy production, the parasite is immobilized and eventually dies.

Side Effects
Mebendazole Winston is well tolerated by adults and children. It has virtually no side effects. Transient abdominal pain and diarrhoea have been reported only rarely, in case of massive infestation and expulsion of worms.
Toxicity
Acute oral toxicity (LD50): 620 mg/kg [Mouse]. Symptoms of overdose include elevated liver enzymes, headaches, hair loss, low levels of white blood cells (neutropenia), fever, and itching.
Precaution
Hepatic impairment. Children. Pregnancy and lactation.
Interaction
Concomitant treatment with cimetidine may inhibit the metabolism of mebendazole in the liver, resulting in increased plasma concentrations of the drug especially during prolonged treatment.
Food Interaction
- Take with or without food.
Mebendazole Winston Disease Interaction
Elimination Route
Poorly absorbed (approximately 5 to 10%) from gastrointestinal tract. Fatty food increases absorption.
Half Life
2.5 to 5.5 hours (range 2.5 to 9 hours) in patients with normal hepatic function. Approximately 35 hours in patients with impaired hepatic function (cholestasis).
Elimination Route
In man, approximately 2% of administered mebendazole is excreted in urine and the remainder in the feces as unchanged drug or a primary metabolite.
Pregnancy & Breastfeeding use
Mebendazole Winston should not be administered during pregnancy and in women thought to be pregnant. It is not known whether mebendazole or its metabolites are secreted in human breast milk. Thus Mebendazole Winston should not be used during lactation unless the potential benefits are considered to outweigh the potential risk associated with treatment.
Contraindication
Mebendazole Winston is contraindicated in pregnancy and in patients who have shown hypersensitivity to the product or any of its components.
Acute Overdose
Symptoms: Alopecia, reversible liver function disturbances, hepatitis, agranulocytosis, neutropenia, glomerulonephritis, abdominal cramps, nausea, vomiting and diarrhoea.
Management: Within the 1st hr after ingestion, gastric lavage may be performed. Activated charcoal may be given if considered appropriate.
Storage Condition
Store between 20-25° C.
