Usefulness of a murine model of hepatic cystic echinococcosis for preclinical drug trials: Efficacy of albendazole vs albendazole nanocrystals.

Cystic echinococcosis is a zoonotic infection caused by the larval stage of Echinococcus granulosus sensu lato. The disease is characterized by the long-term growth of cysts, most commonly in the liver and lungs. Although an ideal model of cystic echinococcosis should induce the development of cysts in the liver and imitate the natural infection route, the murine model of intraperitoneal is still widely used in the field of experimental theraphy.

Anthelmintic Effect of Cannabidiol against .

Cystic echinococcosis is a global parasitic zoonosis caused by infection with the larval stage of . Cystic echinococcosis affects more than 1 million people worldwide, causing important economic costs in terms of management and livestock associated losses. Albendazole is the main drug used in treating human cystic echinococcosis.

Experimental treatment of cystic echinococcosis: Combination therapy with carvacrol and thymol versus albendazole.

Cystic echinococcosis is a worldwide zoonotic disease caused by Echinococcus granulosus sensu lato (s.l.), which produces serious health and economic problems.

The combination of carvacrol and albendazole enhanced the efficacy of monotherapy in experimental alveolar echinococcosis.

Alveolar echinococcosis is a helminthic zoonosis caused by the larval stage of Echinococcus multilocularis. When surgical resection of the parasite is not feasible, pharmacological treatment with albendazole is the only option. Due to the difficulties in achieving the success of treatment, it is necessary to find new drugs to improve the treatment of this disease.

Development of an improved anesthesia protocol to increase CF1 mice survival in a portal vein infection with sensu lato protoscoleces.

In order to optimize the survival rate of animals, the purpose of this study was to evaluate an injectable anesthesia protocol for the development of a murine model of hepatic cystic echinococcosis in female CF-1 mice. Three protocols of injectable anesthesia were evaluated during the infection of mice with sensu lato protoscoleces via the portal vein. The use or not of pre-anesthesia [atropine (0.

In vitro efficacy study of Cinnamomum zeylanicum essential oil and cinnamaldehyde against the larval stage of Echinococcus granulosus.

Hydatidosis or cystic echinococcosis is a disease caused by the larval stage of Echinococcus granulosus sensu lato. Chemotherapy can be used alone or in combination with surgery or percutaneous treatment. Benzimidazoles are the only agents used and approved for treatment, but their efficacy is extremely variable.

Albendazole solid dispersions against alveolar echinococcosis: a pharmacotechnical strategy to improve the efficacy of the drug.

Alveolar echinococcosis is a neglected parasitic zoonosis caused by Echinococcus multilocularis. The pharmacological treatment is based on albendazole (ABZ). However, the low water solubility of the drug produces a limited dissolution rate, with the consequent failure in the treatment of the disease.

Do albendazole-loaded lipid nanocapsules enhance the bioavailability of albendazole in the brain of healthy mice?

Neurocysticercosis is a neglected tropical disease that affects the central nervous system and is the most common cause of human epilepsy acquired in developing countries. Therapeutic failures attributed to medical management of neurocysticercosis with albendazole (ABZ) have been primarily linked to the poor drug absorption rate resulting in low drug level in plasma and brain tissue. The aim of the current work was to characterize and compare the brain pharmacokinetic behavior of ABZ formulated as a suspension or lipid nanocapsules (ABZ-LNCs) in healthy mice.

Drug repurposing for the treatment of alveolar echinococcosis: and effects of silica nanoparticles modified with dichlorophen.

Alveolar echinococcosis is a neglected parasitic zoonosis caused by the metacestode Echinococcus multilocularis, which grows as a malignant tumour-like infection in the liver of humans. Albendazole (ABZ) is the antiparasitic drug of choice for the treatment of the disease. However, its effectiveness is low, due to its poor absorption from the gastro-intestinal tract.

Albendazole-lipid nanocapsules: Optimization, characterization and chemoprophylactic efficacy in mice infected with Echinococcus granulosus.

Cystic echinococcosis (CE), which is caused during the metacestode larval stage of Echinococcus granulosus, is a life-threatening disease and is very difficult to treat. At present, the FDA-approved antihelmintic drugs are mebendazole (MBZ), albendazole (ABZ) and its principal metabolite ABZ sulfoxide (ABZSO), but as these have a therapeutic efficacy over 50%, underlining the need for new drug delivery systems. The aim of this work was the optimization and characterization of previously developed ABZ lipid nanocapsules (ABZ-LNCs) and evaluate their efficacy in mice infected with E.

Albendazole nanocrystals in experimental alveolar echinococcosis: Enhanced chemoprophylactic and clinical efficacy in infected mice.

Human alveolar echinococcosis is caused by the fox tapeworm Echinococcus multilocularis and is usually fatal if left untreated. Medical treatment with albendazole (ABZ) remains an effective option. However, due to its low aqueous solubility, ABZ is poorly and erratically absorbed following oral administration resulting in low drug levels in plasma and liver distribution.

Experimental cystic echinococcosis therapy: In vitro and in vivo combined 5-fluorouracil/albendazole treatment.

Human cystic echinococcosis is a zoonosis caused by the larval stage of the tapeworm Echinococcus granulosus sensu lato (s. l.).

In vitro and in vivo efficacy of carvacrol against Echinococcus granulosus.

Currently, benzimidazoles are used as chemotherapeutic agents and as a complement to surgery and PAIR in the treatment of cystic echinococcosis (CE). They are generally applied at high doses causing side effects and, 50% of cases do not respond favorably to such chemotherapy. The use of essential oils obtained by distillation from aromatic plants would be an effective alternative or complementary to the synthetic compounds, because would not bring the appearance of side effects.

Cystic echinococcosis therapy: Albendazole-loaded lipid nanocapsules enhance the oral bioavailability and efficacy in experimentally infected mice.

Therapeutic failures attributed to medical management of cystic echinococcosis (CE) with albendazole (ABZ) have been primarily linked to the poor drug absorption rate resulting in low drug level in plasma and hydatid cysts. Lipid nanocapsules (LNCs) represent nanocarriers designed to encapsulate lipophilic drugs, such as ABZ. The goals of the current work were: (i) to characterize the plasma and cyst drug exposure after the administration of ABZ as ABZ-LNCs or ABZ suspension (ABZ-SUSP) in mice infected with Echinococcus granulosus, and ii) to compare the clinical efficacies of both ABZ formulations.

In vivo activity of albendazole in combination with thymol against Echinococcus multilocularis.

Human alveolar echinococcosis (AE) is caused by the fox tapeworm Echinococcus multilocularis and is usually lethal if left untreated. The current strategy for treating human AE is surgical resection of the parasite mass complemented by chemotherapy with benzimidazole compounds. However, reliable chemotherapeutic alternatives have not yet been developed stimulating the research of new treatment strategies such as the use of medicinal plants.

Enhanced chemoprophylactic and clinical efficacy of albendazole formulated as solid dispersions in experimental cystic echinococcosis.

Cystic echinococcosis is a chronic, complex, and still neglected disease. Although albendazole has demonstrated efficacy, only about one-third of patients experience complete remission or cure and 30-50% of treated patients develop some evidence of a therapeutic response. Different strategies have been developed in order to improve the albendazole water solubility and dissolution rate.

Could thymol have effectiveness on scolices and germinal layer of hydatid cysts?

Scolicidal solutions remain indispensable in the treatment of hydatid cyst disease. Properties of an ideal solution would be inexpensiveness and the promotion of a rapid and complete scolicidal effect with an absence of local and systemic side effects. From this point of view, no ideal solution and agents have been described yet.
