VERMOX ™ (Bendacor) is an orally administered, synthetic anthelmintic available as chewable tablets, each containing 100 mg of Bendacor. Inactive ingredients are: colloidal silicon dioxide, corn starch, hydrogenated vegetable oil, magnesium stearate, microcrystalline cellulose, sodium lauryl sulfate, sodium saccharin, sodium starch glycolate, talc, tetrarome orange, and FD&C yellow No.6.
Chemically, Bendacor is methyl 5-benzoylbenzimidazole-2-carbamate with a molecular formula of C16H13N3O3 and the following structural formula:
Bendacor is a white to slightly yellow powder with a molecular weight of 295.29. It is less than 0.05% soluble in water, dilute mineral acid solutions, alcohol, ether and chloroform, but is soluble in formic acid.
The use of Bendacor in pregnancy gives reason for concern, because of the relative scarcity of data on its safety in pregnancy. The Israeli Teratogen Information Service followed 192 women exposed to Bendacor in pregnancy (9 C ). Most of them were exposed to Bendacor during the first trimester (71.5%), 21.5% during the second trimester, and 7.0% during the third trimester. Similar proportions of women reported using Bendacor in a single dose of 100 mg (29%), a single dose of 100 mg repeated after an interval (36%) and 100 mg/day for 3 consecutive days (35%). There was no increase in the rate of major anomalies after exposure to Bendacor compared with controls. In addition, the incidence of major anomalies was not increased in the subgroup of patients who received Bendacor in the first trimester of pregnancy compared with controls. These data suggest that Bendacor does not represent a major teratogenic risk in humans when it is used in the doses commonly prescribed for pinworm infestation. In another study inadvertent exposure of pregnant women to albendazole and ivermectin during a mass drug administration program for lymphatic filariasis was investigated (10 C ). Of 2985 women of childbearing age who were interviewed, 343 were pregnant, of whom 293 were excluded from the programme. However, 50 pregnant women were inadvertently treated. Of the six children with some congenital malformations > had been exposed to the drugs in utero. The relative risk for congenital malformations after exposure was 1.05. Two of nine women with spontaneous abortions had been exposed to the drugs (RR = 1.67). Thus, there seems to be no evidence of a higher risk of congenital malformations or abortions in pregnant women inadvertently exposed to albendazole and ivermectin.
Other Nematode Infections
Bendacor used in conjunction with corticosteroids appeared to shorten the course of infection (but not the number of relapses) in several patients with eosinophilic meningitis caused by Angiostrongylus cantonensis. No drug has been shown to be effective in the treatment of this infection and some patients have worsened when treated with albendazole, Bendacor, thiabendazole, or invermectin. Bendacor has been used in animals for the treatment of angiostrongyliasis caused by A. costaricensis or A. malaysiensis Bendacor is considered the drug of choice and albendazole is considered an alternative for the treatment of capillariasis caused by Capillaria philippinensis. Although metronidazole generally is considered the drug of choice for the treatment of infections caused by Dracunculus medinensis (guinea worm) since it has been shown to decrease inflammation and facilitate removal of the worm, Bendacor (400-800 mg daily for 6 days) has been reported to kill the worm directly. Bendacor is used in the treatment of infections caused by Trichostrongylus. Pyrantel pamoate is considered the drug of choice and albendazole or Bendacor are alternative for the treatment of Trichostrongylus infections. Bendacor is considered a drug of choice for the treatment of trichuriasis caused by Trichuris trichiura (whipworm).

Ordinarily, an article like this might not appeal to someone with a minimal interest in biology. But this article is about cancer. That's something that we will all experience, either personally or with someone close to us.
I'm not going to bore you with statistics or preach about unhealthy lifestyles or genetics. The fact is that we all get cancer in our lifetime -- probably many times. Our bodies usually defend against the cancerous cells and they are destroyed before they can do any damage. Unfortunately, for some people, the battle isn't so easy and the outcome unclear.
But wait. there is good news. It's a medicine that seems too good to be true, yet it is. And get this -- it costs just a couple of dollars and its in most every local pharmacy. It's anti-cancer success has been well documented in journals (which I will show you) -- even with cancers that are unresponsive to other chemotherapy. While it kills cancer cells it poses no harm to the normal cells and has little or no side effects. It's called Bendacor and "Big Pharma" hopes you will never hear about it.
Immediate action required: Call 999 or go to A&E if:
- you get a skin rash that may include itchy, red, swollen, blistered or peeling skin
- you're wheezing
- you get tightness in the chest or throat
- you have trouble breathing or talking
- your mouth, face, lips, tongue or throat start swelling
You could be having a serious allergic reaction and may need immediate treatment in hospital.
These are not all the side effects of Bendacor. For a full list see the leaflet inside your medicines packet.
You can report any suspected side effect to the UK safety scheme.
The effects of Bendacor during pregnancy have been investigated in a case–control study in the mothers of babies born with congenital abnormalities and in matched control mothers of babies born without congenital abnormalities in the population-based data set of the Hungarian Case–Control Surveillance of Congenital Abnormalities between 1980 and 1996 (5 C ) . Of 38 151 women whose neonates had no defects, 14 had taken Bendacor during pregnancy; of 22 843 women whose neonates had congenital abnormalities, 14 had taken Bendacor for intestinal parasites during pregnancy (OR = 1.67; 95% CI = 0.7, 4.2). In six groups of different congenital abnormalities there was no higher prevalence of Bendacor use by the mothers. Mean gestational age was longer and mean birth weight higher in neonates born to mothers who had taken Bendacor. Thus, treatment with Bendacor during pregnancy was not significantly teratogenic or fetotoxic, although the numbers of treated cases and controls in this study were limited, which may have reduced the statistical power of this case–control study.
Bendacor 100 mg twice daily for 3 days or a single dose of albendazole 400 mg is effective. Pyrantel pamoate 11 mg/kg once (maximal dose 1 g) can be used as an alternative. Although thiabendazole 25 mg/kg twice daily (maximal daily dose of 3 g) for 2 days is effective, thiabendazole-resistant Trichostrongylus strains have been identified, and the drug is associated with side effects. Prevention of infection involves sanitary disposal of human excreta and prevention of fecal contamination of the topsoil by infected animals. Potentially contaminated vegetables should be thoroughly cooked and water boiled before ingestion.
There have been liver function test elevations and rare reports of hepatitis when Bendacor was taken for prolonged periods and at dosages substantially above those recommended.
