  • the composition is used in a method of reducing an HIV viral load in a human subject infected with HIV, by administering an oral dose of the composition to the subject.
  • Praziquantel, lUPAC name: 2-(Cyclohexylcarbonyl)-1 H,2H,3H,6H,7H,1 1 bH- piperazino (2,1 -a) isoquinolin-4-one is an anthelminthic effective against tapeworm infections and against Schistosome (S. haematobium, S. mansoni and S. japonicium) and many cestode infestations.
  • Praziquantel affects the permeability of the cell membrane resulting in the contraction of schistosomes. The drug further causes vacuolization and disintegration of the schistosome tegument. The effect is more marked in adult worms compared to juvenile worms.
  • Niclosamide is an anthelminthic effective in the treatment of tapeworm and intestinal fluke infections, including Beef Tapeworm (Taenia saginata), Pork Tapeworm (Taenia solium), Fish Tapeworm (Diphyllobothrium latum) and the Dwarf Tapeworm (Hymenolepis nana).
  • Niclosamide works by killing tapeworms on contact. Adult worms are rapidly killed due to uncoupling of oxidative phosphorylation or stimulation of ATPase activity. The killed worms are then passed in the stool or sometimes destroyed in the intestine of a human subject.
  • Albendazole, lUPAC name: methyl N-[6-(propylsulfanyl)-1 H-1 ,3-benzodiazol- 2-yl]carbamate is a broad spectrum anthelminthic that is effective in the treatment of parenchymal neurocysticercosis due to active lesions caused by larval forms of the Pork Tapeworm ( Taenia solium) and for the treatment of cystic hydatid disease of the liver, lung and peritoneum, caused by the larval form of the Dog Tapeworm (Echinococcus granulosus).
  • Albendazole causes degenerative alterations in the tegument and intestinal cells of the worm by binding to the colchicine-sensitive site of tubulin, thus inhibiting its polymerization or assembly into microtubules.
  • the loss of the cytoplasmic microtubules leads to impaired uptake of glucose by the larval and adult stages of the susceptible parasites, and depletes their glycogen stores.
  • Degenerative changes in the endoplasmic reticulum, the mitochondria of the germinal layer, and the subsequent release of lysosomes result in decreased production of adenosine triphosphate (ATP), which is the energy required for the survival of the helminth. Due to diminished energy production, the parasite is immobilized and eventually dies.
  • ATP adenosine triphosphate
  • helminthic infections are believed to significantly suppress the immune mechanisms of the human body thereby further compromising the immune systems of subjects with already compromised immune systems.
  • Such helminthic infections are particularly prevalent in developing countries in which large numbers of people live under poor living conditions and sanitation and where poor nutrition, poverty and lack of education are further contributing factors to the relatively high incidence of helminthic infections.
  • the composition and medicinal product as defined and described hereinabove are thus specifically intended for use as complementary medicaments in the treatment of subjects with compromised immune systems.
  • RNA copies per millilitre (cps/mL) of blood plasma were obtained:
  • the treatment can be provided in blister pack form.
  • the blister pack can be printed with Monday, Tuesday, Wednesday, Thursday, Friday and Saturday, to indicate daily treatments to a user.
  • the invention extends to a dosage form for use in a method of reducing an HIV viral load in a human subject infected with HIV.
  • the dosage form comprises, for administering to persons aged 6 - 18 years, 300mg praziquantel, 250mg niclosamide and 200mg albendazole.
  • the dosage form comprises administering to persons aged older than 18 years, 600mg praziquantel, 500mg niclosamide and 400mg albendazole.
  • the invention extends further to a kit for use in a method of reducing an HIV viral load in a subject infected with HIV as described hereinabove, the kit comprising separate dosage forms of praziquantel, niclosamide and albendazole in the abovementioned amounts for persons aged 6 - 18 years and older than 18 years.
  • the invention extends yet further to a pharmaceutical composition comprising praziquantel, niclosamide and albendazole in the amounts referred to above in relation to the composition in accordance with the first aspect of the invention.
