What is oxamniquine used for?

Oxamniquine is an “antihelmintic,” or anti-worm, medication. It prevents worms from growing or multiplying in your body. Oxamniquine is used only to treat infections caused by the worm Schistosoma mansoni. This is an uncommon infection usually acquired through contact with freshwater in Africa.

What is the mode of action of oxamniquine?

Oxamniquine causes worms to shift from the mesenteric veins to the liver where the male worms are retained; the female worms return to the mesentery, but can no longer release egg. Oxamniquine may associate with an irreversible inhibition of the nucleic acid metabolism of the parasites.

What is the frequency of Oxamniquine?

We found homozygous parasites predicted to be phenotypically OXA-R at a frequency of 5.26% (3/57) in East Africa and 1.06% (2/189) in South America only (Fig 5).

What does praziquantel treat?

This medication should take effect within 1 to 2 hours; however, effects may not be noted outwardly and therefore laboratory tests may need to be done to evaluate this medication’s effectiveness.

Is mebendazole the same as praziquantel?

Although the efficacy of mebendazole is lower than praziquantel, its egg negative conversion rate also reaches 71.4-85%. Mebendazole-medicated salt can be used for treating Echinochasmus fujianensis infection as the presence of co-infection with nematodes.

How effective is niclosamide?

Niclosamide is the drug of choice for treatment of T. saginata and Taenia solium (pork tapeworm) infection; cure rates are approximately 90%. It is not absorbable and thus is nontoxic.
