Albenza (Albendazole) - Summary

 



ALBENZA SUMMARY

Albenza (albendazole) is an orally administered broad-spectrum anthelmintic.

Albenza (albendazole) is indicated for the treatment of the following infections:

Neurocysticercosis.
   Albenza is indicated for the treatment of parenchymal neurocysticercosis due to active lesions caused by larval forms of the pork tapeworm, Taenia solium.

Lesions considered responsive to albendazole therapy appear as nonenhancing cysts with no surrounding edema on contrast-enhanced computerized tomography. Clinical studies in patients with lesions of this type demonstrate a 74% to 88% reduction in number of cysts; 40% to 70% of albendazole-treated patients showed resolution of all active cysts.

Hydatid disease.
   Albenza is indicated for the treatment of cystic hydatid disease of the liver, lung, and peritoneum, caused by the larval form of the dog tapeworm, Echinococcus granulosus.

This indication is based on combined clinical studies which demonstrated non-infectious cyst contents in approximately 80-90% of patients given Albenza for 3 cycles of therapy of 28 days each. (See DOSAGE AND ADMINISTRATION.) Clinical cure (disappearance of cysts) was seen in approximately 30% of these patients, and improvement (reduction in cyst diameter of >/=25%) was seen in an additional 40%.

NOTE: When medically feasible, surgery is considered the treatment of choice for hydatid disease. When administering Albenza in the pre- or post-surgical setting, optimal killing of cyst contents is achieved when three courses of therapy have been given.

NOTE: The efficacy of albendazole in the therapy of alveolar hydatid disease caused by Echinococcus multilocularis has not been clearly demonstrated in clinical studies.

Published Studies Related to Albenza (Albendazole)

Comparison of prednisolone plus albendazole with prednisolone alone for treatment of patients with eosinophilic meningitis. [2009.09]
Corticosteroid and the combination of corticosteroid and antihelminthic drug are safe and beneficial in relieving headaches in patients with eosinophilic meningitis. However, clinical trials comparing the efficacies of these regimens have never been reported.Prednisolone plus albendazole is no better than prednisolone alone for treatment of patients with eosinophilic meningitis.

Combination therapy with albendazole and praziquantel versus albendazole alone in children with seizures and single lesion neurocysticercosis: a randomized, placebo-controlled double blind trial. [2009.05]
CONCLUSIONS: A combination therapy for albendazole and praziquantel was statistically comparable to sole therapy with albendazole in eradicating lesions and preventing seizures.

A randomised, double-blind field trial of ivermectin alone and in combination with albendazole for the treatment of Mansonella perstans infections in Uganda. [2009.03]
The effect of a single dose of ivermectin alone (150-200microg/kg body weight) or in combination with albendazole (total of 400mg) in Mansonella perstans infection was assessed in a randomised, double-blind field trial in two endemic communities in Mukono and Luwero districts of Uganda... However, in general both treatment regimens in both communities had limited effect on microfilarial intensities, and only one individual (given combination treatment in Luwero) was mf-negative at 6 months and 12 months after treatment.

Patterns of soil-transmitted helminth infection and impact of four-monthly albendazole treatments in preschool children from semi-urban communities in Nigeria: a double-blind placebo-controlled randomised trial. [2009.02.19]
BACKGROUND: Children aged between one and five years are particularly vulnerable to disease caused by soil-transmitted helminths (STH). Periodic deworming has been shown to improve growth, micronutrient status (iron and vitamin A), and motor and language development in preschool children and justifies the inclusion of this age group in deworming programmes. Our objectives were to describe the prevalence and intensity of STH infection and to investigate the effectiveness of repeated four-monthly albendazole treatments on STH infection in children aged one to four years... CONCLUSION: Results from this study show that the moderate prevalence and low intensity of STH infection in these preschool children necessitates systematic treatment of the children in child health programmes.

Randomized controlled trial of albendazole in new onset epilepsy and MRI confirmed solitary cerebral cysticercal lesion: Effect on long-term seizure outcome. [2009.01.15]
No trials to date have focused on long-term seizure outcome in solitary cerebral cysticercal lesion (SCCL), which is believed to produce a relatively benign form of epilepsy. This is a prospective randomized controlled study to evaluate the effect of Albendazole on long-term seizure outcome in patients with MRI-confirmed solitary cerebral cysticercal lesion (SCCL)...

Clinical Trials Related to Albenza (Albendazole)

Effectiveness of Combined Albendazole and Ivermectin Treatment for Intestinal Worm Infections [Completed]
The aim of this study is to compare the efficacy and impact on growth of two drug treatments against intestinal worms in schoolchildren from a rural area of Guatemala. According to the World Bank, these intestinal worms are one of the top causes of childhood health problems in many areas of the developing world (The World Bank, 1993). Infected children are more likely to have inadequate nutrition due to the worm infections and are more likely to be shorter in height and weigh less than children who are not infected. After collecting height and weight information, we will split the children into two groups. One group will receive albendazole and the other group will receive combined albendazole/ivermectin. Both groups will be receiving albendazole, the current standard of care treatment. Ivermection is expected to improve efficacy and nutritional benefit as well as add increased scope of treatment for the worm Strongyloides, and ectoparasites such as scabies and head lice. Both treatment regimens and the combination have been used millions of times in the developing world and are safe to use. Co-administration of drugs would be a more efficient use of the opportunity to access schoolchildren and provide deworming treatment.

Effect of Albendazole Dose on Treatment of Lymphatic Filariasis [Recruiting]
This study is conducted in Kerala, India. It will determine whether a new treatment regimen of albendazole and diethylcarbamazine (DEC) for lymphatic filariasis can eliminate the disease more quickly than the standard regimen. Lymphatic filariasis is caused by infection with very small parasitic worms that are spread by mosquitoes. The disease can cause swelling of the arms, legs, breast and scrotum and can progress to permanent swelling of the legs or arms called elephantiasis. The study will see if a higher and more frequent dose of albendazole is better at clearing filarial worms from the blood than the current treatment.

Healthy people between 18 and 55 years of age who are in good health and who are infected with filarial worms may be eligible for this study.

Participants undergo the following procedures:

3-day hospital stay at the Filariasis Chemotherapy Unit of the T. D. Medical College Hospital in Kerala, India

- Random assignment to receive either: 400 mg albendazole and DEC 300 mg given once a

year for 2 years (standard treatment); or 800 mg albendazole and DEC 300 mg given once a year for 2 years; or 800 mg albendazole and DEC 300 mg given twice a year for 2 years.

- Urine pregnancy test for women of childbearing age .

- Ultrasound test to look for filarial worms.

- Treatment dose.

- Monitoring for symptoms

A Double-Blind, Placebo-Controlled Trial of Albendazole in HIV-Positive Patients With Intestinal Microsporidiosis [Completed]
To evaluate the efficacy (stool frequency) and safety (adverse experiences) of albendazole, administered for 28 days, compared to placebo and for 62 days in open-label fashion, in treating intestinal microsporidiosis in HIV-positive patients. To assess the effect of albendazole on stool volume, weight gain, microsporidial counts in small bowel biopsies, and on the relationship between microsporidial counts in stool and stool frequency and volume. To correlate microsporidial counts with the clinical course of microsporidiosis.

Efficacy Albendazole and Levamisole Against STH on Unguja [Completed]
Field epidemiological studies undertaken during 2005 in four village locations in Northern Unguja, Zanzibar examined mothers and their pre-school aged children for helminth infections.

The prevalence of Ascaris lumbricoides was found to have remained relatively high despite community-wide treatment with the mass administration of Albendazole (a WHO recommended de-wormer) in coordination with community vitamin A supplementation.

One hypothesis for this is that the children and mothers had Ascaris infections more tolerant to Albendazole that subsequently failed to clear. It is necessary to compare the present drug efficiency of Albendazole (first-line de-wormer) with Levamisole (second-line de-wormer) on STH infections such patients a case-control setting to shed light on the putative resistance of local Ascaris/Trichuris to albendazole.

In so doing, this should clarify whether there is resistance developing towards Albendazole and have possible implications for introducing combination therapies of Levamisole and Albendazole for first line de-worming mothers and their children in the future.

Ivermectin Versus Albendazole for Chronic Strongyloidiasis [Recruiting]
A prospective controlled trial to compare the efficacy and safety of 7-day albendazole, single dose ivermectin, and 2-single dose ivermectin in 72 patients with chronic strongyloidiasis will be conducted at Siriraj Hospital, Bangkok, Thailand.
