Fenbendazole vs mebendazole

Mebendazole MBZ is a medication used to treat a number of parasitic worm infestations. Mebendazole is usually well tolerated. Mebendazole came into use inafter it was developed by Janssen Pharmaceutica in Belgium. Mebendazole is a highly effective, broad-spectrum antihelmintic indicated for the treatment of nematode infestations, including roundworm, hookworm, whipworm, threadworm, pinworm, and the intestinal form of trichinosis prior to its spread into the tissues beyond the digestive tract.

Other drugs are used to treat worm infections outside the digestive tract, as mebendazole is poorly absorbed into the bloodstream. It kills parasites relatively slowly, and in those with very heavy infestations, it can cause some parasites to migrate out of the digestive system, leading to appendicitis, bile duct problems, or intestinal perforation.

To avoid this, heavily infested patients may be treated with piperazine, either before or instead of mebendazole. Piperazine paralyses the parasites, causing them to pass in the feces. Evidence for effectiveness for this disease, however, is poor. Mebendazole and other benzimidazole antithelmetics are active against both larval and adult stages of nematodes, and in the cases of roundworm and whipworm, kill the eggs, as well.

Paralysis and death of the parasites occurs slowly, and elimination in the feces may require several days. Mebendazole is pregnancy category C, which means it has been shown to cause ill effects in pregnancy in animal models, and no adequate studies of its effects in human pregnancy have been conducted. Whether it can be passed by breastfeeding is unknown. Mebendazole sometimes causes diarrhea, abdominal pain, and elevated liver enzymes.

In rare cases, it has been associated with a dangerously low white blood cell count, low platelet countand hair loss, [12] [13] with a risk of agranulocytosis in rare cases. Carbamazepine and phenytoin lower serum levels of mebendazole. Cimetidine does not appreciably raise serum mebendazole in contrast to the similar drug albendazoleconsistent with its poor systemic absorption.

Stevens—Johnson syndrome and the more severe toxic epidermal necrolysis can occur when mebendazole is combined with high doses of metronidazole. Poor absorption in digestive tract makes mebendazole an efficient drug for treating intestinal parasitic infections with limited adverse effects.

However mebendazole has impact on mammalian cells mostly by inhibiting polymeration of tubulin dimers, thereby disrupting essential microtubule structures such as mitotic spindle. Mebendazole is available as a generic medication. In the developing world the wholesale cost is between USD 0. InAmedra also bought the U. The result of these acquisitions created a monopoly on these medications and the price increased dramatically.

Several studies show mebendazole exhibits potent antitumor properties. MBZ significantly inhibited cancer cell growth, migration, and metastatic formation of adrenocortical carcinomaboth in vitro and in vivo.

What Is the Difference between Albendazole and Mebendazole?

From Wikipedia, the free encyclopedia. Medication for parasitic worm infestations. IUPAC name. Interactive image.This is a remarkable story about a little pill that began use as a worm treatment for children, and became a medicine to treat, and prevent, cancer.

Most of us are familiar with this medication. It is usually used to treat pinworms, roundworms, whip worms, and hookworms. Children sometimes acquire these parasites adults can as welland the whole family is given a prescription for mebendazole. I have written for this medication many times over the past 32 years for the treatment of these parasites. Mebendazole has been in common use for over forty years as an antiparasitic, and has a good safety profile.

It is fairly inexpensive, at about dollars a pill. This little pill, known for its good safety profile and few side effects, has been used to treat, and prevent, cancer. The fact is we all get cancer in our lifetime….

Our immune system quickly identifies and destroys these abnormal cells, as long as our immune system is in optimal shape. This is why I write so much about diet, lifestyle, and natural supplements that boost the immune system, especially when its comes to boosting natural killer NK cells.

Mebendazole kills cancer cells, even those that are unresponsive to other chemotherapy, without causing harm to normal cells, and with little or no side effects.

Scientists have long known how MBZ works to kill parasites, and as it turns out, cancer cells have something in common with parasites. MBZ selectively targets the spindles of both, while leaving healthy cells untouched. What is a cellular spindle? Great question! Spindles are a type of scaffold-ladder system in our cells. They are also called microtubules. This network of rigid microtubules inside a cell give shape and structure to the cell.

The spindles also transfer various molecules to different parts of the cell, functioning like an interstate system.Remember Me Forgot your password? Forums Blogs Articles Groups. Sport Horse Spotlight. Real Estate Spotlight.

Keep conversations productive, on topic and civil.A serendipitous finding in lab mice made by research professor Gregory Riggins and neurosurgeon Gary Gallia is creating excitement as a possible treatment for glioblastoma, an aggressive brain tumor.

Ordinarily, he and his colleagues have no trouble triggering glioblastoma cells to proliferate in mice. But over the course of several months inthey encountered one group of mice in which the tumors would not grow.

After some investigating, the scientists discovered that the mice had been treated with the veterinary antiparasitic drug fenbendazole. Searching the literature, they found reports that fenbendazole had been shown to inhibit cancer growth.

Then, by trial and error, they determined that the related drug mebendazole—which has been used for the last 60 years to treat parasites in the human gastrointestinal tract—might also hold potential for stalling glioblastoma.

With that, Riggins, Gallia and their research team launched a program to understand the drug, improve its effectiveness against glioblastoma cells and have it manufactured for testing in patients. The scientists believe the drug helps obstruct tumors by inhibiting formation of strands of tubulin—proteins needed by cancer cells to grow.

Glioblastoma is a fast-moving cancer. He and his team are looking to pair it with other drugs. They expect that their formulation of mebendazole will also work in pediatric cases. Challenge: To find an effective drug to combat glioblastoma, an aggressive brain tumor. Approach: Riggins and Gallia are using mebendazole, a drug in the family of compounds that includes fenbendazole, a veterinary antiparasitic that had serendipitously been discovered to prevent tumor growth in lab mice.

Progress: A phase 1 clinical trial of mebendazole, involving 24 patients, is currently underway. View our phone directory or find a patient care location. Privacy Statement.

I Want ToMounting research is showing how the drug fenbendazole, most typically used as a canine deworming drug in veterinary practice, can block sugar uptake in cancer cells, kill cancer cells, reduce tumour size and even overcome cancer drug resistance, making it another 'repurposed drug' that can be used to treat cancer.

Back ina team of researchers at top American Hospital Johns Hopkins was trying to grow tumours in laboratory mice. Except with one group of mice, they failed. The reason they discovered, was that the mice had been de-wormed 1 with an anti-parasitic drug.

They read more about the drug, only to find that anti-cancer activity had previously been reported writes Gilly Bertram. Fenbendazole comes from a class of drugs called benzimidazoles, which are commonly used in veterinary medicine for anti-worm and parasite treatments.

They are used effectively to kill worms such as roundworms, hookworms, whipworms and some tapeworms as well as parasites. Fenbendazole is branded under names like Panacur and Safe-Guard. Research suggests that fenbendazole inhibits tumour growth by inducing apoptosis cell death of tumour cells.

Researchers are also finding that fenbendazole could be useful for overcoming drug resistance which is a common setback in conventional cancer therapies. In a paper published in Nature 2the authors report that fenbendazole appears to act as a destabilising agent of microtubules which are important structural proteins making up the cytoskeleton of cells and these proteins allow the microscopic organs inside our cells called organelles to move throughout the cell.

Mebendazole: From Pinworm Cure To Cancer Cure?

The researchers conclude that there is evidence of cancer cell death by the modulation of multiple cellular pathways, which may lead to the effective elimination of cancer cells. The use of anthelminthic drugs with cancer, however, is nothing new.

Scientific literature prior to the Nature paper demonstrated the effective use of fenbendazole for various types of cancer cells such as Non-small Cell Lung Cancer 3Lymphoma 4 Metastatic prostate cancer cells 5 and Glioblastoma, or GBM 6. A further anti-cancer mechanism the researchers found with fenbendazole was that it blocked the uptake of glucose in cancer cells, depriving them of their primary fuel.

This discovery supports the use of fenbendazole as an complementary therapy to chemotherapy and radiotherapy as well as metabolic therapies. Joe took a combination of nutrients alongside fenbendazole, while deciding not to change his diet. It worked! Febendazole toxicity and safety in humans. Although the original clinical approval for fenbendazole was for intestinal parasites and not for cancer, the drug has already gone through human clinical trials and so all of the clinical trial work related to toxicity has already been done and febendazole has been deemed safe for human consumption for many years.

There is no doubt it has strong properties but some cancer experts prefer to use Mebendazole, which they obviously feel has more. Go to: Repurposed drugs as cancer treatments. Subscribe Free e-Newsletter. Market Place. Instant confirmation. Book now - pay when you stay.

Active bacteria including L. Para-Free plus. Triple action kills parasites, yeasts and a colon cleanse.Mebendazole, a well-known anti-helminthic drug in wide clinical use, has anti-cancer properties that have been elucidated in a broad range of pre-clinical studies across a number of different cancer types. Significantly, there are also two case reports of anti-cancer activity in humans. The data are summarised and discussed in relation to suggested mechanisms of action.

Based on the evidence presented, it is proposed that mebendazole would synergise with a range of other drugs, including existing chemotherapeutics, and that further exploration of the potential of mebendazole as an anti-cancer therapeutic is warranted.

A number of possible combinations with other drugs are discussed in the Appendix. Mebendazole MBZ is a broad-spectrum benzimidazole anti-helminthic drug, in the same class as albendazole, flubendazole, oxfendazole, and others. It is commonly prescribed to treat a range of parasitical worm infections, including threadworm, tapeworms, roundworms, and other nematode and trematode infections in humans and domestic animals. For human use, the most common formulation of MBZ is as mg chewable tablets.

The dosage varies according to the type of helminthic infection being treated. Pinworms are treated with a single mg treatment, whereas roundworms or hookworms are treated with mg twice a day for three days. MBZ, along with albendazole, is also used on a long-term basis for the treatment of human cystic and alveolar echinococcosis also known as hydatid disease.

Indeed, there are documented cases of treatment periods of ten or more years [ 12 ]. MBZ has low toxicity, though patients may suffer from transient symptoms, such as abdominal pain and diarrhoea in cases of massive infection and excretion of parasites.

Hypersensitivity reactions, such as rash, urticaria, and angioedema, have been observed on rare occasions. MBZ is contraindicated during pregnancy. Caution is also recommended in treating infants below the age of 2, primarily due to a lack of data in such cases [ 3 ].

fenbendazole vs mebendazole

In the case of long-term administration of MBZ for echinococcosis, the evidence is that, in general, the treatment is well tolerated, but the specific treatment for some patients has to be discontinued. For example, in one open-labelled observational study, the patients treated with MBZ for alveolar echinococcosis average: 24 months experienced few adverse reactions, and in only three patients of 17the treatment was changed to albendazole due to intolerable side effects reversible alopecia, psychological disturbance, and drop in performance [ 4 ].

Dosing with a high-fat meal is known to modestly increase bioavailability [ 5 ]. Chronic dosing of MBZ increases plasma concentration by a factor of between two and three compared to single dose [ 36 ].

For patients not on chronic treatment, an initial treatment of MBZ at the same dose produced a mean peak plasma level of The poor bioavailability has long been recognised, and strategies to improve this remain actively researched, these strategies have included alternative formulations with vegetable oils [ 7 — 9 ], altering the crystalline structure of MBZ [ 10 ] and investigations into PEGylation [ 11 ]. Albendazole and MBZ interact with cimetidine, which inhibits metabolism and has been documented to increase MBZ plasma levels, maximum serum levels rose to This may be an important interaction with clinical relevance in that it suggests a strategy to increase bioavailability should that be required to increase the anti-cancer effect.

Given that cimetidine may also have some anti-cancer activity [ 13 ], it also suggests that an investigation into possible synergies with MBZ over and above the effect on bioavailability would be an interesting avenue to explore. High intra- and inter-patient variability may be an important factor in assessing response to MBZ as a possible anti-cancer therapeutic.

However, it is clear that plasma levels achieved by chronic and high-dosing schedules are in the range necessary for clinical activity based on the pre-clinical evidence assessed in the following section. Cells were arrested in the G2-M phase before undergoing apoptosis. Overall, the in vitro results showed that MBZ inhibited lung cancer cell growth 5-fold compared to controls.

Additionally, the authors confirmed the growth inhibitory effects of MBZ against breast, ovary, colon carcinomas, and osteosarcoma, producing IC50s that varied from 0. Treated animals showed a dose-dependent arrest in tumour growth. The experiment was also repeated with C3H mice and the K mouse cell line, and MBZ inhibited tumour growth in this syngeneic mouse model also.

Mice treated with MBZ showed no side effects. Finally, the investigators also assessed whether MBZ might inhibit the formation of lung metastases and injected A cells into the tail vein of mice. In untreated controls, approximately metastatic colonies appeared in the lungs by 21 days. Treatment with the established anti-microtubule agent paclitaxel showed no such reduction in colony formation. Further pre-clinical evidence of MBZ anti-cancer activity was shown in adrenocortical cancer in [ 16 ], both in vitro and in vivo.

HR, SW and WI normal fibroblast cells lines were treated with different concentrations of MBZ in vitroand the two cancer cells lines showed dose-dependent growth arrest, with IC50 of 0.I have cancer. Stage 4 perotonial cancer. I am not a number.

You are not a number. And cancer is beaten at every stage. I live in Houston. I have had my blood drawn more times than I can count, a colonoscopy not as bad as I thought it would beand two CT scans … one of those scans with a tube up my butt. Not fun. In any case, I am in this thing, like it or not. So if you or a loved one is fighting cancer, know that I am fighting it right next to you.

Benzimidazoles

I have a wife, three kids, parents, and extended family that I love — plenty of reasons to keep fighting. I am proceeding with conventional cancer treatment but I have also been exploring complementary and alternative methods to improve my outcome.

I want to tackle my cancer from every angle possible. I am not going to make it easy on cancer. Reading through the wealth of knowledge online and within several books, I came across the use of off-label drugs to assist in the fight against all kinds of cancers.

Off-label refers to the use of drugs for a purpose not intended by the pharmaceutical company. Off-label drugs can be over-the-counter or prescription drugs.

Doctors have the legal ability to prescribe off-label drugs if they deem fit, including controlled substances. Jane has beat cancer not once, but twice. Jane attributes her miraculous defeat of cancer with the use of off-label drugs and a variety of supplements. Many years ago, she was told she had a few weeks to live and decided to take matters into her own hands and it made all the difference.

In this post, I want to focus on two drugs, one of which Jane took, that I am finding very interesting because numerous success stories are being linked to this family of drug. The drugs of interest are mebendazole and fenbendazole. Jane took mebendazole, more on fenbendazole later.

Mebendazole is traditionally used to kill parasitic worms and other parasites living inside the body. In the medical world, antiparasitical drugs are referred to as anthelmintic. Specifically, mebendazole is a benzimidazole which is technically a compound composed of benzene and imidazole.

The associated drugs include albendazole, thiabendazole, riclabendazole, flubendazole, mebendazole and fenbendazole. Jane McLelland is an advocate of mebendazole and states in her book that mebendazole is a chemical compound that slows down fast cell division and works similarly to some chemotherapy drugs but without the same toxicity.

According to Jane, and many others, there is evidence that mebendazole reduces abnormal cell signaling Sonic Hedgehog which in turn helps to destroy cells associated with tumors that suppress immunity.

The Care Oncology Clinic COCwhich Jane is a staunch supporter of, includes mebendazole in their cocktail of four off-label drugs used to stave off a wide variety of cancers. I currently take mebendazole with a prescription but supplement it with Vitamin E. I will explain later why I supplement with Vitamin E.
