Albendazole is a clinically important anthelminthic agent known to have variable and low oral bioavailability. The aim of this work was to determine whether albendazole, a CYP3A4 substrate, is also a substrate for the multidrug efflux transporter P-glycoprotein. Both in vitro and in vivo methods were used to assess the role of P-glycoprotein-mediated albendazole transport. In cultured LLCPK1, L...

The impact of albendazole (400 mg) and praziquantel (40 mg/kg body weight) treatment of schoolchildren was compared with placebo according to the presence of anaemia (haemoglobin concentration < 11. 0 g/dl) and heavy (> 5000 epg) or light (< 5000 epg) hookworm egg load. The study was conducted in rural Tanga. Medication was administered in September 1994 and children were followed-up in January...

A patient with intravitreous cysticercosis was treated with the new anthelminthic drug, praziquantel. A transient toxic effect on the cysticerus was observed, but the drug was unable to kill the parasite.

The hookworms Necator americanus and Ancylostoma duodenale infect approximately 1 billion people worldwide. The prevalence of hookworm infection increases with age in children, typically reaching a plateau in late adolescence, whereas the intensity of infection may continue to increase throughout adulthood. Hookworms cause intestinal blood loss in amounts proportional to the number of adult wor...

The anthelminthic efficacy of the crude aqueous extract of Acanthus montanus (Nees) T. Anders (Acanthaceae) against strongylid nematodes of small ruminants was investigated using the in-vitro egg hatch and larval growth inhibition assays. Faecal samples collected per rectum from sheep and goats were subjected to parasitological examination using the McMaster counting technique with a yield of 7...

Intervention measures against anemia available to plantation workers during pregnancy include fortified food supplements (thriposha) and iron-folate supplements containing 60 mg elemental Fe. The effectiveness of these intervention measures was studied in 195 subjects whose iron and nutritional status were assessed at < 24 and > 32 wk of gestation. Taking thriposha conferred no significant bene...

Schistosomiasis is a major neglected tropical disease. Control of schistosomiasis currently relies on a single drug, praziquantel, and despite its efficacy against the all schistosome species that parasitize humans, it displays some problematic drawbacks and alone is ineffective in counteracting adverse pathologies associated with infection. Moreover, due to the development of the potential eme...

A detailed investigation was performed with the aim to find out the indigenous medicinal plants having anthelminthic action. Ten (10) indigenous medicinal plants were primarily selected and the ethanol extracts were prepared for anthelminthic trial and determination of anthelminthic properties in vitro and in vivo against the gastro-instestinal nematodes in goat during the period from July 2006...
